12(5+2y)=4y-(6-9y) How to Solve

kvv77 [185]

Answer:

y = -6

Step-by-step explanation:

12 (5 + 2y) = 4y- (6 - 9y)

= 60 + 24y = 4y - 6 + 9y

= 60 + 24y = 13y - 6

= 24y - 13y = -6 - 60

= 11y = -66

y = -6

Y = x - v/b ; solve for x

elena-s [515]

Answer:

x = y + v/b

Step-by-step explanation:

You can solve for x by adding v/b to both sides since that is what will isolate x the quickest and that is what you want to do when you need to solve for something.

By adding v/b to both sides, you will end up with x=y+v/b and that’s your answer!

Hope this helps!

The formula for a trapezoid relates the area A, the two bases, a and b, and the height, h. A=h ( a+b ) 2 Solve for b.

Lelu [443]

I believe the right equation for determining the area of a trapezoid is as below,
A = h(a + b)/2

To determine the expression for b which is the length of one of its bases, we multiply the equation by 2.

2A = h(a + b)

Then, divide both sides of the equation by h,

2A/h = a + b

Then, subtract a from both sides of the equation,
2A/h - a = b

Lastly, interchange the sides of the equation to reveal the answer.
<em> </em>
<em> b = 2A/h - a </em>

PLS HELP WILL MARK BRAINLIST IF ANSWER IS CORRECT !! :) FILL IN THE BLANKS

andrew-mc [135]

Answer:

Part 1) The volume of the storage body is 576 cubic feet

Part 2) To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box

Part 3) Sheila can fit 64 boxes into the truck

Step-by-step explanation:

step 1

Find the volume of the storage body

we know that

The volume of the of the storage body is equal to the volume of two rectangular prism

The volume of a rectangular prism is equal to

$V=LWH$

First rectangular prism (top)

$V=(15)(6)(8-6)=180\ ft^3$

Second rectangular prism (bottom)

$V=(15-4)(6)(6)=396\ ft^3$

The volume of the storage body is

$V=180+396=576\ ft^3$

step 2

we know that

To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box

step 3

substitute the given values

$\frac{576}{9}= 64\ boxes$

therefore

Sheila can fit 64 boxes into the truck
