Answer:

It cannot be answered if we don't figure out what x means. IF we knew what X is we can multiply 6 by x and then add 7.

an example would be if x was 3. we could figure out the answer by just doing (6*3)+7=25

If 9 chairs can fit in one box, and you have 3,456 chairs, just divide how many chairs you have by how many can fit in the box in order to find how many boxes you will need.

3,456/9 = 384
384 boxes will be needed

zimovet [89]

The equation 13x+30=134 can be used to find the number of months Kenneth can receive internet service.

Step-by-step explanation:

Given,

Start up fee to receive internet = $30

Per month charges = $13

Total amount = $134

Let,

x be the number of months.

y be the total cost.

y = 13x+30

Putting y=134

$134=13x+30\\13x+30=134$

The equation 13x+30=134 can be used to find the number of months Kenneth can receive internet service.

olasank [31]

Answer:

$x = 15 \: \: .....(5(15)- 14) = 61$

$(9x + 16 )= (5x - 14) + 90 \\ 9x - 5x = 90 - 14 - 16 \\ 4x = 60 \\ x = \frac{60}{4} \\ x = 15$
