DISTRIBUTIVE PROPERTY AND COMBINING LIKE TERMS(SIMPLIFY EACH EXPRESSION)

1 answer:

3 0

The distributive property: a(b + c) = ab + ac

-3(7b + 1) - 4(-b + 3) = -3(7b) - 3(1) - 4(-b) - 4(3)

= -21b - 3 + 4b - 12 = -17b - 15

V-10=-3 solve the equation

Evgesh-ka [11]

Answer:

v =7

Step-by-step explanation:

Simplifying

v + -10 = -3

Reorder the terms:

-10 + v = -3

Solving

-10 + v = -3

Solving for variable 'v'.

Move all terms containing v to the left, all other terms to the right.

Add '10' to each side of the equation.

-10 + 10 + v = -3 + 10

Combine like terms: -10 + 10 = 0

0 + v = -3 + 10

v = -3 + 10

Combine like terms: -3 + 10 = 7

v = 7

Simplifying

v = 7

At Micaela's Printing Company LLC there are two kinds of penting presses: Model A which can print 60 books per day and Model B w

devlian [24]

A+B=15 —>A+15=B(plug this into the other equation)
60a+30b=600
60a+30(a+15)=600
60a+30a+150=600
90a+150=600
90a=450
A=5 (plug back in to first equation)
A+B=15
5+B=15
B=10

They have 5 of the Model A and 10 of model B.

I'm stuck on this homework question. I forgot the formula to find the side. This is 9th grade geometry.

dexar [7]

Answer:

x = 2root(22)

see image.

Step-by-step explanation:

The triangle shown is one big triangle cut into two more smaller triangles: one medium-sized and one smaller.

ALL THREE TRIANGLES ARE SIMILAR BY AA.

Set the two smaller triangles up so you can see the corresponding sides. x is the short leg in one triangle and it is the long leg in the smallest triangle. Set up a proportion.

22/x = x/4

crossmultiply

x^2 = 22•4

x^2 = 88

square root both sides.

x = sqroot(88)

x = 2sqroot(22)

see image.
