Answer:

The distributive property makes it possible

Step-by-step explanation:

Step one:

given the expression a(b + c )

the first step is to open the bracket, that is multiply all the terms in the bracket by a, so multiply b by a and c by a also.

Step two:

Thus, this property is called the distributive property of multiplication

a*b+ca

Which expression uses the greatest common factor and distributive property to find 10+50?

Rudiy27

Ab+ac=a(b+c) where a is the greatest common factor
find greatest common factor of 10 and 50
10=1,2,5,10
50=1,2,5,10,25,50
greatest common is 10
a=10
10(1)+10(5)=10(1+5)=10(6)=60

Solve, 3y(4y−1)−2y(6y−5)=9y−8(3+y)

igomit [66]

Answer:

3y(4y-1)-2y(6y-5)=9y-8(3+y)

12y∧2-3y-12y∧2+10y=9y-24-8y

12y∧2-12y∧2-3y+10y=9y-8y-24

7y=y-24

7y-y=-24

6y=-24

y=-24/6=-4

Type the correct answer in each box. Use numerals instead of words. if necessary, use / for the fraction bar(s).

Marrrta [24]

Answer:

$\frac{11}{12} - \frac{1}{3} = \frac{7}{12}$

Step-by-step explanation:

Given

See attachment for question

Required

Solve

We have:

$\frac{11}{12} - \frac{1}{3}$

Take LCM and solve

$\frac{11}{12} - \frac{1}{3} = \frac{11 - 4}{12}$

$\frac{11}{12} - \frac{1}{3} = \frac{7}{12}$
