First you need to set up your equation.

If you read the question it states one equation IS THE SAME AMOUNT of another equation so here it is:

3x+7= 2x+18

You want to find out x in both equations so I’ll help step by step

1. Subtract 2x from both sides

This leaves you with x+7=18

2. Then subtract 7 on both sides

This leaves you with x=11

So x equals 11 for equations.

You can check by plugging in 11 in x. If you get 40 on both sides....

CONGRATS!! You did it

I hope this helped. Have a great day!

If d=3 what is the answer? 7b to the power of three +10
Sati [7]

Answer:

199 if it's 7b^3 + 10

9271 if it's (7b)^3 + 10

Step-by-step explanation:

You just substitute the 3 in for d. If your expression was 7b^3 + 10, then only b is being raised to 3.

So 3^3 is 27, 27*7 is 189, 189+10 is 199.

If the expression was (7b)^3 + 10, then first you multiply 7 and 3 to get 21. Then you raise 21 to the power of 3, which is 9261. Then you add 10, which is 9271.

iragen [17]

Given that,

Alonzo is $120 in debt. He makes $15 per hour. He wants to have at least $75 left over after he has paid off his debt.

To find,

The inequality and the solution.

Solution,

Let he make $x per hour. Here, $120 is fixed. $15 is added per hour.

ATQ,

120 + 15x\ge 75

For atleast, we use \ge.

Subtract 120 from both sides.

120 + 15x-120\ge 75-120\\\\15x\ge -45\\\\x\ge -3

So, the required answer is greater than -3.
