Answer:

Correct option is:

a. 3/2

Step-by-step explanation:

We have to determine the number which must be multiplied to the equation

\dfrac{2}{3}x=10

to form the equation x=15

Clearly the left hand side of the equation is converted to x

Hence, on multiplying the original equation by 3/2, we get

\dfrac{2}{3}x\times \dfrac{3}{2}=10\times \dfrac{3}{2}

which is equal to

x=15

Hence, Correct option is:

a. 3/2

Find the midpoint of A and B where A has coordinates (-7, 1)<br> and B has coordinates (3,-5).
zepelin [54]

Answer:

A (-7, 1) = (X1, Y1)

B (3, -5) = (X1, Y2)

Now,

Mid point = (X1 + X2÷2, Y1 + Y2 ÷ 2)

= {-7+3÷2, 1+(-5)÷2}

= (-4÷2, 1-5÷2)

= (-4÷2, -4÷2)

= (-2, -2)

Step-by-step explanation:

I hope it will help you to study.
