Step-by-step explanation:
22=-2x+4(-4x-17)
solve for x pls
Answer:
x=-5
Step-by-step explanation:
22=-2x+4(-4x-17)
We move all terms to the left:
22-(-2x+4(-4x-17))=0
We calculate terms in parentheses: -(-2x+4(-4x-17)), so:
-2x+4(-4x-17)
We multiply parentheses
-2x-16x-68
We add all the numbers together, and all the variables
-18x-68
Back to the equation:
-(-18x-68)
We get rid of parentheses
18x+68+22=0
We add all the numbers together, and all the variables
18x+90=0
We move all terms containing x to the left, all other terms to the right
18x=-90
x=-90/18
x=-5
Answer:
Step-by-step explanation:
22 = -2x + 4(-4x - 17)
22 = -2x + 4*(-4x) - 4*17
22 = -2x - 16x - 68 {Combine like terms}
22 = -18x - 68 {Add 68 to both sides}
22 + 68 = -18x
90 = -18x {Divide both sides by (-18)
90/-18 = x
x = -5

Answer:
$284.99 should go to Mr. Aceves’ class, $174.41 should go to Mrs. Baca’s class, and $140.60 should go to Mr. Canyon’s class.
Step-by-step explanation:
Firstly, to calculate the portions each class should have, we should find the proportion each class takes up.
Hence, let's say A represents Mr. Aceves' class, B represents Mrs. Baca's class, and C represents Mr. Canyon's class.
The total number of box tops collected would be 3760 + 2301 + 1855 = 7916 box tops.
Therefore, the total proportions would be:
A = [tex]\frac{3760}{7916}[/tex]
B = [tex]\frac{2301}{7916}[/tex]
C = [tex]\frac{1855}{7916}[/tex]
Hence, we can finally multiply these proportions with the total prize to find the appropriate division:
Mr. Aceves' class gets [tex]\frac{3760}{7916} \cdot 600 \approx 284.99[/tex].
Mrs. Baca's class gets [tex]\frac{2301}{7916} \cdot 600 \approx 174.41[/tex].
And Mr. Canyon's class gets [tex]\frac{1855}{7916} \cdot 600 \approx 140.60[/tex].
Finally, $284.99 should go to Mr. Aceves’ class, $174.41 should go to Mrs. Baca’s class, and $140.60 should go to Mr. Canyon’s class.
Hope this helped!
△ABC has vertices A(–2, –2), B(1, –1), and C(2, 0). Find the image of △ABC after a dilation centered at the origin with a scale factor of 2.
Answer:
see explanation
Step-by-step explanation:
since the dilatation is centred at the origin , then multiply each of the coordinates of A, B, C by the scale factor 2, that is
A' = (2(- 2), 2(- 2) ) = A'(- 4, - 4 )
B' = (2(1), 2(- 1) ) = B'(2, - 2 )
C' = (2(2), 2(0) ) = C'(4, 0 )

Step-by-step explanation:
In ΔFGH, \text{m}\angle F = (6x-14)^{\circ}m∠F=(6x−14) ∘ , \text{m}\angle G = (4x-8)^{\circ}m∠G=(4x−8) ∘ , and \text{m}\angle H = (x+15)^{\circ}m∠H=(x+15) ∘ . Find \text{m}\angle F.M∠F.
Answer:
[tex]\angle F =\bold{88^\circ}[/tex]
Step-by-step explanation:
Given a [tex]\triangle FGH[/tex] with the following angles:
[tex]\text{m}\angle F = (6x-14)^{\circ}[/tex]
[tex]\text{m}\angle G = (4x-8)^{\circ}[/tex]
[tex]\text{m}\angle H = (x+15)^{\circ}[/tex]
To find:
[tex]\text{m}\angle F[/tex] = ?
Solution:
Here, we can simply use the angle sum property of a triangle to find the value of [tex]\text{m}\angle F[/tex].
As per the angle sum property of a triangle, the sum of all the interior angles a triangle is equal to [tex]180^\circ[/tex].
[tex]\angle F + \angle G + \angle H = 180^\circ[/tex]
Putting all the given values in the above equation, we get:
[tex](6x-14)^{\circ} + (4x-8)^{\circ} + (x+15)^{\circ} = 180^\circ\\\Rightarrow 11x-7=180^\circ\\\Rightarrow 11x=180+7\\\Rightarrow 11x=187\\\Rightarrow x = \bold{17}[/tex]
Putting the value of [tex]x[/tex] in [tex]\angle F[/tex]
[tex]\text{m}\angle F = (6x-14)^\circ\\\Rightarrow \text{m}\angle F = (6\times 17-14)^\circ\\\Rightarrow \text{m}\angle F = \bold{88^\circ}[/tex]
In the diagram below, determine the value of x:
9514 1404 393
Answer:
55°
Step-by-step explanation:
130° is an external angle to the small triangle at lower left, so is the sum of the remote interior angles. The unmarked interior angle at the bottom of that triangle is then 130° -30 = 100°.
That is an exterior angle of the large triangle that has remote interior angles of 45° and x°. So, ...
x° + 45° = 100°
x° = 100° -45°
x° = 55°
_____
Alternate solution
The sum of the interior angles of a quadrilateral is 360°. Three of the angles in the bounding quadrilateral are x°, 45°, 30°. The fourth is the reflex angle that is (360° -130°) = 230°. So, we have ...
x° +45° +230° +30° = 360° . . . . . angles CCW from lower right
x° = 360° -305°
x° = 55°

Slope = -7;(4,-30)
Answer:
y=-7x-2
Step-by-step explanation:
I assume you need the equation for the line, so that's what I'm solving for here.
1. Start by putting the slope and the coordinates into point slope form, which is y-y1=m(x-x1)
y+30=-7(x-4)
2. Distribute -7 to (x-4) (or multiply x and -4 by -7).
y+30=-7x+28
3. Subtract 30 from both sides to get y by itself.
y=-7x-2
A unicycle wheel has a diameter of 16 inches. How many inches will the unicycle travel in 7 revolutions?
Use π = 3.14 and round your answer to the nearest hundredth of an inch.
Answer:
The unicycle will travel 351.68 inches in 7 revolutions
Step-by-step explanation:
The circular shape moves a distance equal to its circumference in each revolution, then the rule of the distance of the circular shape travels n turns is D = π d n, where
d is the diameter of the circular shapen the number of revolution∵ A unicycle wheel has a diameter of 16 inches
∴ d = 16 inches
∵ The unicycle will travel 7 revolutions
∴ n = 7
→ Substitute them in the rule of the distance above
∵ D = π(16)(7)
∵ π = 3.14
∴ D = 3.14(16)(7)
∴ D = 351.68 inches
→ No need to round it, it is in the hundredth of an inch
∴ The unicycle will travel 351.68 inches in 7 revolutions
Which equation represents this problem? The time it takes Tomás to bike to the community center is 2 minutes less than half the time it takes him to bike to the city park. It takes Tomás 18 minutes to bike to the community center. Let p = the time it takes Tomás to bike to the park.
A. 2p+12=18
B.12p+2=18
C.2p–12=18
D.12p–2=18
Answer:
The equation that represents this problem is [tex]\frac{1}{2}[/tex] p - 2 = 18 ⇒ D
Step-by-step explanation:
Let us solve the question
∵ p is the time it takes Tomás to bike to the park
∵ The time it takes Tomás to bike to the community center is 2 minutes
less than half the time it takes him to bike to the city park
→ That means multiply p by [tex]\frac{1}{2}[/tex] , then subtract 2 from it
∴ The time to the community center = [tex]\frac{1}{2}[/tex] (p) - 2
∴ The time to the community center = [tex]\frac{1}{2}[/tex] p - 2
∵ It takes Tomás 18 minutes to bike to the community center
→ Equate The time to the community center by 18
∴ [tex]\frac{1}{2}[/tex] p - 2 = 18
∴ The equation that represents this problem is [tex]\frac{1}{2}[/tex] p - 2 = 18

Betty is making a quilt made of various patterns . She buys 3 sheets of fabric that each have an area of 30 square feet. She cuts them up into sections that are each 2/5 of a square foot . How many sections will she have total
Answer:
She will have 12 sections per fabric and 36 sections in all
Step-by-step explanation:
Betty buy 3 fabrics of 30 ft²
If she cut each to 2/5 of 1 ft²
Then she will have
30 × 2/5
= 6 × 2
= 12
She will have 12 for each fabric and for the 3 fabrics, she will have
12 × 3 = 36
Step-by-step explanation:
Answer:
225 sections
Step-by-step explanation:
Each fabric has an area of 30 sq ft.
All 3 fabrics have a total area of 3 * 30 sq ft = 90 sq ft.
Each sections has an area of 2/5 sq ft.
number of sections = total area of fabric / area of each section
90/(2/5) = 90 * 5/2 = 450/2 = 225
Answer: 225 sections

Answer:
2. Definition of supplementary angles
3. [tex]\angle 1 + \angle 2 = \angle 1 + \angle 3[/tex]
4. [tex]\angle 2 = \angle 3[/tex]
5. Definition of congruent angles
Step-by-step explanation:
Required
Fill in the gaps
1. Given
Supplementary angles: [tex]\angle 1[/tex] and [tex]\angle 2[/tex]
Supplementary angles: [tex]\angle 1[/tex] and [tex]\angle 3[/tex]
2. Supplementary angles add up to 180.
So:
[tex]\angle 1 + \angle 2 = 180[/tex]
[tex]\angle 1 + \angle 3 = 180[/tex]
3. Apply transitive property on (2)
[tex]\angle 1 + \angle 2 = 180[/tex] and [tex]\angle 1 + \angle 3 = 180[/tex], then
[tex]\angle 1 + \angle 2 = \angle 1 + \angle 3[/tex]
4. Subtract [tex]\angle 1[/tex] from both sides
[tex]\angle 1 - \angle 1 + \angle 2 = \angle 1 + \angle 3 - \angle 1[/tex]
[tex]\angle 1 - \angle 1 + \angle 2 = \angle 1 - \angle 1+ \angle 3[/tex]
[tex]\angle 2 = \angle 3[/tex]
This property is called the subtraction property
5. If [tex]\angle 2 = \angle 3[/tex],
Then [tex]\angle 2[/tex] and [tex]\angle 3[/tex] are congruent
