ASAP HELP Which equation is equivalent to: 3r=90−5 ?
A. 3r+5=90
B. −3r=−90−5
C. −3r=90+5
D. 3r=90+5

Answer: 94, 86

Step-by-step explanation:

x + x/2 + 39 = 180

x + x/2 = 180 - 39

x = 94

Other angle is 180 - 94 = 86

Answer:

A) 9 => 6 => 3 => 0 => -3 => -6

B) Using Formula

[tex]a_{n}= a_{1} + d(n-1)[/tex]

=> [tex]a_{n } = 9+3(n-1)[/tex]

=> [tex]a_{n}= 9+3n-3\\a_{n} = 3n+6[/tex]

Answer: [tex]a_{n }= 3n+6[/tex]

Answer:

x = 11.5

Step-by-step explanation:

Given

2x - 3 = 20 ( add 3 to both sides )

2x = 23 ( divide both sides by 2 )

x = [tex]\frac{23}{2}[/tex] = 11.5

Answer:

x = 44°

Step-by-step explanation:

Since this is an isosceles triangle, the other angle that isn't defined is also 68°. So, since all the angles add up to 180°,

x + 68(2) = 180

x + 136 = 180

x = 44°

Answer:

44 is the answer

Step-by-step explanation:

First option is the correct answer

Answer:

its the first option 2 1/3

Step-by-step explanation:

Answer:

Because the dashed triangle is smaller than the original it's a reduction. The scale factor is 1/3 because if we look at the altitudes of the triangle, the original is 6 and the dilated is 2 and 2 / 6 = 1 / 3.

Answer:

The single transformation that maps a onto c is the reflection of the triangle a  about the line y = -x

Step-by-step explanation:

To answer the question, we note that the result of reflection of a point (x, y) across the x axis is given as follows;

Coordinates before reflection = (x, y), Coordinates after reflection = (x, -y)

Also, when we rotate a  point, (x, y), 90° clockwise, we have;

Image point before 90° clockwise rotation = (x, y), Image point after 90° clockwise rotation = (y, -x)

Therefore, the rotation of the point (x, -y), 90° clockwise will give

Image point before 90° clockwise rotation = (x, -y), Image point after 90° clockwise rotation = (-y, -x)

Which gives the combined transformation as (x, y) → (-y, -x) which is the rule equivalent to reflection about the line y = -x.

Answer:

B have 5 more cranes than Ava.

Step-by-step explanation:

As per question statement:

Number of cranes with Ava = 100

Number of cranes with B = [tex]\frac{3}{4}[/tex] of the paper cranes that Ava has

[tex]\therefore[/tex] Number of cranes with B = [tex]\frac{3}{4}\times 100 =75[/tex]

Now, let us proceed step by step.

Step 1: Ava gave [tex]\frac{9}{20}[/tex] of her cranes to B:

i.e. [tex]\frac{9}{20} \times 100 = 5 \times 9 =45[/tex] cranes given to B

Now, number of cranes with Ava = 100 - 45 = 55

Number of cranes with B = 75 + 45 = 120

Step 2: B gave [tex]\frac{1}{4}[/tex] of her paper cranes to Ava:

i.e. [tex]\frac{1}{4} \times 120 = 30[/tex] cranes given to B

Now, number of cranes with Ava = 55 + 30 = 85

Number of cranes left with B =  120 - 30 = 90

So, the answer is:

Number of cranes that B have more than that of Ava = 90 - 85 = 5

Answer:

area of triangle

= 1/2 × base × height

= 1/2 × 3 units × 4 units

= 6 units²

Answer:

40 ft

Step-by-step explanation:

Triangle ABC is given by AB = 13 ft, BC = 10 ft, ∠ACB = 50° and AC = b. Let AB = a = 13 ft, BC = c = 10 ft

Since two sides are given and one angle is given, to find the other side, we use the cosine formula. The cosine formula is given by:

[tex]c^2=a^2+b^2-2abcos(C)\\b^2=c^2-a^2+2abcos(C)\\substituting\ values:\\b^2=13^2-10^2+2*10*bcos(50)\\b^2=169-100+12.86b\\b^2-12.86b=69\\b^2-12.86b-69=0\\ solving\ simultaneously\ gives:\\b=16.93\ ft[/tex]

The perimeter of the triangle is given by:

Perimeter = AB + BC + AC = 13 + 10 +16.93 = 39.93 ft ≈ 40 ft

Answer:

[tex] \tan(a) = \frac{28}{45} [/tex]

look from the tan A angle , the opposite is 28 and adjacent is 45

Answer:

x ≈ 4

Step-by-step explanation:

We use tan∅ to solve this:

tan30° = x/7

7(tan30°) = x

x = 4.04145

Remember that tangent is opposite over adjacent.

Answer:

x over quantity 2x plus 3 equals 40 over 60

Step-by-step explanation:

Let light clothes=x

Number of dark clothes = 2x + 3,

Dark clothes are 60% of total clothes

Light clothes=100%-60%

=40%

Light clothes / dark clothes = percentage of light clothes / percentage of dark clothes

x / 2x+3 = 40 / 60

x over quantity 2x plus 3 equals 40 over 60

    Expression for this situation will be [tex]\frac{x}{2x+3}=\frac{60}{40}[/tex].

Let the number of dark cloths = y

And the number of light cloths = x

"The number of dark cloths is three more than twice the number of light cloths".

Therefore, equation will be,

y = 2x + 3 ----- (1)

"The laundry is 60% dark cloths"

Equation for this statement will be,

y = [tex]\frac{60}{100}(x+y)[/tex]

y = 0.6x + 0.6y

y - 0.6y = 0.6x

0.4y = 0.6x

[tex]\frac{y}{60}=\frac{x}{40}[/tex]

Now substitute the value of y from equation (1),

[tex]\frac{2x+3}{40}=\frac{x}{60}[/tex]

[tex]\frac{2x+3}{x}=\frac{40}{60}[/tex]

[tex]\frac{x}{2x+3}=\frac{60}{40}[/tex]

  Therefore, expression for this situation will be [tex]\frac{x}{2x+3}=\frac{60}{40}[/tex].

Answer:

Step-by-step explanation:

A 2 × 2 matrix has 2 rows and 2 columns

Let us assume that matrix A is expressed as

a b

c d

The determinant of matrix A would be

(a × d) - (b × c)

Given that the determinant of matrix A is 3, it means that

ad + bc = 3

If we switch the rows, the first row becomes cd and the second row becomes ab. If we multiply the first row by 6 and the second row by 2, the matrix becomes

6c 6d

2a 2b

The determinant would be

(6c × 2b) - (2a × 6d)

Determinant = 12bc - 12ad

Answer:

-14

Step-by-step explanation:

First make sure the fractions on the right have the same denominator.

LCM of 3 and 4 = 12.

So,

Numerator of fractions = 8x-4 and 9x

Now they have the same denominator, combine both fractions.Now you have

-x-4/12=5/6

Rearrange and solve

-x-4 = 10

-x = 14

x = -14
