5. 25 = x + 3
It is a one step equation. You just need to subtract 3 on both sides to get x.
6. 2b - 7 = 15
This is a two step equation. You need to add 7 on both sides and then divide both sides by 2 to get b.
7. 10m = 90
Finally, this is a one step equation. You need to divide both sides by 10 to find m.
If it was a 75% discount, then u r actually paying 25%
so....25% of the original price is $ 11
0.25x = 11
x = 11 / 0.25
x = 44 <=== the original price
Answer:
37/5
Step-by-step explanation:
Q = p(r + s)
Use the distributive property
Q = pr + ps
Q = p x r + p x s
Q = p x p + r x s
Q = p^2 + rs
Subtract rs from both sides
Q - rs = p^2
Square root both sides
sqrt Q - rs = p
