Answer:

x=1

Step-by-step explanation:

First find a common denominator between 7 and 4 which is 28, Multiply both equations by 28 eliminating the denominators so now you have theses two equations: 4(2x + 12) = 7(3x + 5) distribute these equations to get:

8x + 48 = 21x +35 now you want to get the x's on one side so 8-21 = -13 which as an equation so far would be -13x + 48 = 35 now do 35-48 = -13 so you can have 13x alone on one side. Your final equation now before you solve is

-13x = -13 the divide -13 by -13 to get 1.

Hope this helps you understand it better

What is the equation shown in the graph? Explain your answer.
Yuliya22 [10]

Answer:

y=x

Step-by-step explanation:

The graph is going 1 up and 1 to the right. You can plug in a value for x and get y. So if you plug in 1 for x, you get 1 for y and if u plug in 2 for x, you get 2 for y, so when you graph (1, 1) and (2, 2) you know the graph is y=x.

Big Smiles Toy Company needs to pack marbles into a box. The company has two boxes they can use. Box A is 9 inches wide, 13 inch
shtirl [24]

Answer:

Big Smiles Toy Company should choose Box B as its volume is  82.5 inch^3 larger than Box A

Step-by-step explanation:

Given

Dimension of Box A= 9 inches width, 13 inches length, 11.5 inches height

Dimension of Box B =14 inches width, 8.5 inches length, 12 inches height

Volume of Box A= Length\timeswidth\times height=9\times13\times11.5= 1345.5 inches^3

Volume of Box B =Length\times width\times height= 14\times8.5\times12= 1428 inches^3

Difference = Volume of Box B - Volume of Box A = 1428 - 1345.5 = 82.5inches^3

Box B has 82.5 inch^3 volume larger than Box A

What is the solution set for 2X - 1 > 7?
Mariana [72]
2x - 1 > 7 ; Start
2x > 8       ; Add 1 to each side of the inequality
x > 4          ; Divide both sides by 2

So, x have to be less than 4 in order to be in the solution set.
