Step-by-step explanation:

 4          7          28

  x     =    <===

3            7          21

u can find equivalent fractions by multiplying the numerator and denominator by the same number

4/3 * 2/2 = 8/6...this would be equivalent

4/3 * 3/3 = 12/9so is this

I could go on, but I think u get it

another way this could be done is proportionsbecause they are nothing but equivalent fractions

4 / 3 = x / 21cross multiply and solve for x

(3)(x) = (4)(21)

3x = 84

x = 84/3

x = 28 <===

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

44
