(5s)/7=30
mutiply both sides by 7, that makes it cancel the fraction
(5s)7/7=30 times 7
5s times 7/7=210
5s times 1=210
5s=210
divide both sides by 5
5s/5=210/5
s times 5/5=42
s times 1=42
s=42

Answer:

d) (9*3/4)+y

Step-by-step explanation:

b) 9+y*(3/4)

This expression is not equivalent, as the original expression, y+9*\frac{3}{4} , has 9 multiplied to \frac{3}{4} instead of y. You can interchange values like this when it comes to addition, but not multiplication.

c) (y+9)(3/4)

This expression is also not equivalent. After opening up the parentheses, it would again result in y being multiplied to \frac{3}{4}.

(y+9)(3/4)\\= y(3/4)+9(3/4)

d) (9*3/4)+y

This expression is equivalent, as 9 and \frac{3}{4} are still being multiplied together and y is added to the product. We can actually rearrange this to look like the original expression:

(9*3/4)+y\\=y+(9*3/4)\\=y+(9*\frac{3}{4} )\\=y+9*\frac{3}{4}

I hope this helps!

m - 3 = 3(b - 3)
m - 3 = 3b - 9
m + 6 = 3b
m/3 + 2 = b

5 years from now:
m + 5 = 2(b + 5)
m + 5 = 2b + 10
m - 5 = 2b
m/2 - 5/2 = b

combine:
m/3 + 2 = m/2 - 5/2

1. multiply by 6
2m + 12 = 3m - 15

2. add 15 - 2m to both sides
27 = m

Marry is 27 years old.
