In 3-10 use the distributive property to find each missing factor
Elanso [62]

The missing factor in the equation is -21

<h3>What is a distributive factor?</h3>

The Distributive Property introduces the multiplication operator an existing mathematical statement that involves the addition operator.

From the complete question, the equation is given as:

6 \times x= (3 \times 7) + (x \times 7)

Where x represents the missing factor.

So, we have:

6x= (21) + (7x)

Remove brackets

6x= 21 + 7x

Collect like terms

6x-7x= 21

Evaluate the like terms

-x= 21

Divide both sides by -1

x= -21

Hence, the missing factor in the equation is -21

The ratio of girls to boys in the grade is 9 to 10. If there are 225 girls, how many boys are there?
MArishka [77]

Answer:

250 boys

Step-by-step explanation:

We know that the ratio is 9:10 from girls to boys

Take 225 and divide it by 9

225 ÷ 9 = 25

So we know that 25 is a factor of 225

We can the number of boys and multiply it by 25 to get 250

If we put it in the ratio form:

225:250 = 9/10

Check work:

25 x 9 = 225

25 x 10 = 250
