Answer:

a) 3x - 11

b) 10x + 4

Step-by-step explanation:

a) The negative sign before the (x+5) means to subtract those values. Reverse the signs. Then combine like terms:

4x –6 –x –5. 4x–x–6–5

3x –11

b) Put all the x terms together.

Put all the integers together.

Add. Adding a negative is the same as subtracting.

4x+x+5x = 10x

+6-2 = 4

Combine them:

10x + 4

GalinKa [24]

Let, number of solid color gift sold is x and printed gift wrap is y.

Also, number of printed paper sold , 325.

Expressing, it in mathematical equation :

y = 325    ....... 1)

Also, The band needs to earn $2,500 for an upcoming competition.

So ,

3.5x + 5y = 2500    ....... 2)

Solving equation 1 and 2 :

3.5x + 5(325) = 2500

3.5x = 2500 - 1625

3.5x = 875

x = 250

Therefore, number of solid paper they must sell is 250.

Hence, this is the required solution.

4 feet by 4 feet by 8 feet what is the volume in cubic feet?
dusya [7]
Volume is computed by multiplying the length, the width, and the height of an object.

In this case, 4 feet by 4 feet by 8 feet means these are the measures of length, width, and height of an object.

Volume = 4 ft * 4 ft * 8 ft = 128 ft³ or 128 cubic feet.

Finger [1]

Answer:

x=2

Step-by-step explanation:

Substitute y=0    0=0.5(x-2) 21

multiply the numbers     0=10.5(x-2)        *(21x0.5)

remove the parenthesis     0=10.5x-21

move the variable      -10.5x=-21

divide both sides by   -10.5

solution     x=2
