Answer:
w = 4
Step-by-step explanation:
you would do this by re-arranging the equation
6 = 5w-10-w (move w to the other side)
6 = 4w-10 (because 5w-w = 4w)
6+10=4w (move 10 to the other side)
16 = 4w (add 6 and 10)
4 = w (divide both sides by 4)
Answer:
22.5
Step-by-step explanation:
find the scale factor
13.5/9 = 1.5
or
18/12 = 1.5
Then times 15 by this to get x
15 x 1.5 = 22.5
Answer:
x = 3
Step-by-step explanation:
x*6 = 6x, then we divide both sides by 6 to get x alone. 6x/6 = 18/6.
x = 3, 18 divided by 6 is 3.
25% of what is 9.50..
0.25x = 9.50
x = 9.50 / 0.25
x = 38
so Johns bill was $ 38
Let's start by turning it into a decimal.
- to turn any percent into a decimal you move the decimal point two places to the left.
Decimal= 5.85
To turn into fraction you know 5 is the whole number and you have 85 hundredths. Just put that in fraction form.
5 and 85/100
Now simplify by dividing both by 5
Answer is
5 and 17/20
