Answer:

Not equivalent

Step-by-step explanation:

A fraction is a part of whole .

Two fractions are said to be equivalent if their lowest forms are same .'A fraction is said to be in lowest form if .

Given :

Number of girls = 12

Number of boys = 16

So, fraction =

 =

Number of girls = 26

Number of boys = 14

So, fraction =

As , these fractions are not equivalent .

The equivalent expression after combining the like terms of the expression 9y+y is 10y.

Given an expression:

9y + y

It is required to find the equivalent expression for this expression after combining the like terms.

Like terms are the terms in an expression or an equation that has the same variable to it or is constant.

They can be operated together.

Here, 9y and y are having the same variable, y.

So, they are like terms.

So, add 9y and y.

9y + y = y(9 + 1)

          = 10y

Hence the expression is 10y.

Answer:

D  -1

Step-by-step explanation:

3(x+1) = 2(x-1)

Use distributive property and get;

3x+3 = 2x-2

Add 2 to both sides,

3x+5 = 2x+4

Subtract 2x from both sides

1x+5 = 4

Subtract 5 from both sides

1x=-1

x = -1
