Step-by-step explanation:
5(2x + 1) = 50 what is x
Answer:
4.5
Step-by-step explanation:
multiply inside the brackets
5 × 2x = 10x, 5 × 1 = 5
10x + 5 = 50
subtract 5 on both sides (50 - 5 = 45) to give
10x = 45
divide 10 on both sides
45 ÷ 10 = 4.5, so x = 4.5

Step-by-step explanation:
a line goes through the point (8,3) and has a slope m=4. Write an equation that represents that line.
Answer:
y=4x-29
Step-by-step explanation:
y-y1=m(x-x1)
y-3=4(x-8)
y=4x-32+3
y=4x-29
Answer:
y = 4x - 29
Step-by-step explanation:
You will use the slope-intercept form y = mx + b
Your point (8, 3) will be substituted for (x, y) and 4 will be substituted for the slope(m)
y = mx + b
3 = (4)(8) + b
Simplify
3 = 32 + b; now subtract 32 from both sides to keep a balanced equation.
3 - 32 = 32 + b - 32
-29 = b
Finally, substitute your slope(m) = 4 and the y-intercept(b) = -29 back into the slope-intercept form
y = 4x - 29

Step-by-step explanation:
Since 1/3 of 12 is 4, we are trying to find the two thirds of an unknown number x that equals 4. We can represent this as the equation 2/3*x=4. Multiplying three on both sides, we get 2x=12. Dividing two on both sides, we get x=6. Therefore, the answer is 2/3 of 6.

Step-by-step explanation:
a. 24/31, 20/27
(31 is prime)
b. 8/9, 24/36
(this one doesn't work since it would have to be 3/4) which isn't a proportion

A rectangle has a height of 8 inches and a base of 12 inches. If we double the height, by how many inches will the perimeter increase?
Perimeter is the total sum of the 4 sides.

During a sale, a store offered a 15% discount on a tablet computer that originally sold for $460. After the sale, the discounted price of the tablet computer was marked up by 15%. To the nearest whole number, what percent of the original price was the price after markup?
The percent of the original price after markup is 98%
Mark up and discountsGiven the following parameters
Original price of tablet = $460If during a sale, a store offered a 15% discount on a tablet, the new price after discount will be:
New price = 0.85 * 460
New price = $391If the tablet computer was marked up by 15% after the discount, then the price after the markup is given as:
Price after markup = 1.15 * 391To get the required percent;
x% of 460 = 450

Brandon has a jar of quarters and dimes with a total value of $10.05. The number of quarters is 3
less than twice the number of dimes. How many quarters and how many dimes does Brandon
have?
Answer:
Brandon has 18 Dimes and 33 Quarters [Beware: The problem does not state that Brandon owns the coins - he just has them. Check your pockets]
Step-by-step explanation:
Let D and Q stand for the numbers of Dimes(D) and Quarters(Q). I'll use pennies instead of dollars, so avoid the clutter of decimal points.
We are told that:
Q = 2D - 3 [The number of quarters is 3 less than twice the number of dimes.]
and
25Q + 10D = 1005 [total value of $10.05]
Substitute the value of Q in the first equation in the second, so that we have an equation with just one unknown, D.
25(2D-3) + 10D = 1005
50D - 75 + 10D = 1005
60D = 1080
D = 18
Q = 2D - 3
Q = 2(18) - 3
Q = 33
=============================
Check
25Q + 10D = 1005
25(33) + 10(18) = 1005 ?
825 + 180 = 1005 YES
----
Q = 2D - 3 ?
33 = 2(18) - 3 YES

What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The inequality is given as,
(5/8) m > −40
Solve the inequality, then we have
(5/8) m > −40
m > −40 × 8 / 5
m > −8 × 8
m > −64

A cross section of an attic is shaped like a trapezoid. It has an area of 37.4 square meters. One base is 6.4 meters and the other base 12.3 meters long. What is the height of the cross section
Answer:
4m
Step-by-step explanation:
see image. The area of the trapezoid is
Area=1/2 (b1 + b2)h
We can fill in the area and the two bases that were given. Then we solve for h to find the height.
37.4 = 1/2 (6.4+12.3)h
Add inside the ( ).
37.4 = 1/2 (18.7)h
Multiply
the 1/2 × 18.7
37.4 = 9.35h
Divide by 9.35
37.4/9.35 = h
4 = h
The height is 4 meters

From the problem we know
a + c = 128
and
$5.40c + $9.20a = $976.20
1) solve the equation to alpha
a+c-c = 128 -c
a+0=128-c
a=128-c
2) substitute (128 - c) for a in the second equation and solve to c
$5.40c + $9.20a = $976.20 become
$5.40c + $9.20(128 - c) = $976.20
$5.40c + ($9.20 × 128) - ($9.20 - c) = $976.20
$5.40c - $9.20c + $ 1177.6 = $976.20
