Answer:
x=2 or x=
4/5
Step-by-step explanation:
Negative case: -(5x-7) = 3
Multiply
-5x+7 = 3
Rearrange and Add up
-5x = -4
Divide both sides by 5
-x = -(4/5)
Multiply both sides by (-1)
x = (4/5)
Then find the positive case: (5x-7) = 3
Rearrange and Add up
5x = 10
Divide both sides by 5
x = 2
Hi there, seems that you need help. I'm going to put these in parts!
Part A: <span>Create an equation that shows the amount of wages earned, W, for working x hours in a week when there is no overtime.
</span>Part A: W =6x
<span>Part B: Create an equation that shows the amount of wages earned, S, for working y hours of overtime. Hint: Remember to include in the equation the amount earned from working 40 hours.
</span>Part B: Since without overtime it is 6 $ per hour and you need to make 40 hours
you would multiply 6 *40 = 240
So <span>S = 240 + 9y
</span>
<span>Part C: Andrew earned $330 in 1 week. How many hours (regular plus overtime) did he work?
</span>Part C: [Substitute]
Since Andrew earned 330 you would substitute it for S
<span>
330 = 240 + 9y</span> <--- solve for y
330 ( - 240 ) = 240 ( - 240 ) 9y < ---- subtract 240 from each side
90 = 9y
90 / 9 = 9y / 9 <----- divide by 9
10 =y Andrew worked 10 hours for overtime
Check
330 = 240 + 9(10)
330 = 240 + 90
330 = 330 <-- your answer is <span>10</span>
Answer:
Its A= B * H
Step-by-step explanation:
Which means Area = (Your base times your height)
Answer:
1 y=-1/10x
2 y=-x-8
3 y= 7/3x or 2 1/3x
Step-by-step explanation:
1 -x=10y
divide -x and 10 by 10
2 y+8=-x
subtract 8
3 -4+7x+4=3y
divide everything by 3
