Answer:

Step-by-step explanation:

Equation

2x + 3x + 8 + 7x - 2 = 90

Solution

Combine like terms on the left

12x + 6 = 90 Subtract 6 on both sides

12x = 90 - 6

12x = 84 Divide by 12

x = 84/12

x = 7

I think there are no solutions - firstly, you can't add two numbers and get one solution, and add the same two numbers up again and get a different solution!

also, if you plot the two lines on a graph they never intersect, showing there are no values of x or y that satisfy both equations.

14. Andrew earns $6.25 per hour. He works 4 hours per day, 5 days

swat32

Answer:

$125 per week

Step-by-step explanation:

Andrew earns $6.25 per hour. If he works for 4 hours, solution will be:

$6.25 × 4 = $25 per day.

If Andrew works 5 days per week, then he earns

$25 × 5 = $125 per week.

Therefore by estimate, Andrew earns $125 per week.

Solve for Y in General 12x − 3y = −6

ella [17]

Answer:

y = 4x + 2

Step-by-step explanation:

$12x - 3y = -6\\\rule{150}{0.5}\\12x-12x-3y=-6-12x\\\\-3y=-6-12x\\\\\frac{-3y=-6-12x}{-3}\\\\y = 2 + 4x\\\\\boxed{y = 4x + 2}$

Hope this helps.

Is Y=7.5x proportional or non proportional

kipiarov [429]

Hi , the answer is proportional , every time when you see an equation that has the Y first then a number next to a x , that equation tells you that there is a proportional relationship.
