Answer:
x = 7
Step-by-step explanation:
We are told one quarter of x is equal to 7 , then the equation is
x = 7 ( multiply both sides by 4 to clear the fraction )
x = 28
Answer:
r<-8
Step-by-step explanation:
Answer:
32.6 - y= 10.2
Step-by-step explanation:
The equation to solve this problem can be written as
32.6 - y= 10.2
Where y is the number that was substracted from 32.6.
If we make y subject of formula we have
y= (32.6-10.2)
y=22.4
Which means the number that was substracted from 32.6 is 22.4 and there difference is 10.2
Answer:
<em>-5/4</em>
Step-by-step explanation:
7(x + 4) + 1x - 9 * 2 = -8x + -10
Distribute 7 on left side. Multiply 9 * 2 on left side.
7x + 28 + 1x - 18 = -8x + -10
Combine like terms on left side.
8x + 10 = -8x + -10
Add 8x to both sides. Subtract 10 from both sides.
16x = -20
Divide both sides by 16.
x = -20/16
Reduce the fraction.
x = -5/4
