Both of the first 8 - N = 22 N - 8 = 22 Represent the difference between a number and 8 is 22 as it is not mentioned that either 8 or the unknown number N is greater so both of the first two represent the difference between a number and 8 is twenty two.

Answer:

The Answer is N - 8 = 22

this is because the question ask the difference of a <em>number</em> and <em>eight</em> is twenty-two, which means a number (N) comes first before the difference ( - ) is eight (8) is (=) twenty two (22) following this order gives the answer above in bold.

The expression 120-15x represents how many invitations Luanne has to address after x days. The expression 120 + 15(7-x) represen

Aloiza [94]

Answer:

not possible.

Step-by-step explanation:

number of invitations luanne has to address after x days = 120-15x

number of invitations Darius has to address after x days = 120 + 15(7-x)

so, if the number of invitations should be the same for both of them,

we have to equate their number of invitations

120-15x = 120 + 15(7-x)

subtracting 120 from both the sides,

-15x = 15(7-x) = 105 -15x

adding we 15x on both sides, we wont find any solution for x.

so, this isnt possible or the question must be wrong.

A teacher runs a total of 48 city blocks in a rectangular pattern. If the width of the run is 3x and the length of the run is 5x

Ghella [55]

Answer:

P = 16x + 8

Step-by-step explanation:

Perimeter of a rectangle

= 2(L + W)

Given

L = 5x + 4 and

W = 3x

Therefore

Perimeter = 2(5x + 4 + 3x)

Rearrange the expression

P = 2(5x + 3x + 4)

P = 2(8x + 4)

Now expand the bracket

P = 2 x 8x + 2 x 4

P = 16x + 8
