Question

Find the value of x

Answer 1

Answer:

4) 4

5) 6.5

6) 14

Step-by-step explanation:

Question 4 equation: $(\frac{12*5}{2} * 2) + (\frac{5x}{2} *2) = 80$ ⇒ $60 + 5x = 80$ ⇒ $5x = 20$ ⇒ $x=4$.

Question 5 equation: $16x=104$ ⇒ $x=6.5$.

Question 6 equation: $\frac{10x}{2} = 70$ ⇒ $5x=70$ ⇒ $x=14$.
