Answer:

Answer:

A. 9

Step-by-step explanation:

${p}^(3 ) + √(64) / q \n (plug \: p = 2 \: and \: q = 8 )\n = {2}^(3) + √(64) / 8 \n = 8 + 8 / 8 \n = 8 + 1 \n = 9$

Step-by-step explanation:

Julia is saving money for the down payment on a car. She plans to save for one year. Her parents have offered to contribute $50 a month to her savings. How much does Julia need to save each month in addition to her parents' contribution if she wants to have a $2700 down payment on a car at the end of the year? Define a variable and write an equation to represent this situation.

Answers

Answer:

$12x+600=2700$

$175

Step-by-step explanation:

Let x represent money saved by her in one month.

So money saved by her in one year (12 months) would be $12x$ .

We can represent our given information as:

$12x+600=2700\n12x=2700-600\n12x=2100\nx=(2100)/(12)\nx=175$

Therefore, she needs to save $175 per month.

3. Irvin cut a 47 in. wire into two pieces. The longer piece is 13 in. longer than the shorter piece. What is the length of the longer piece?_________ in.

Please Help!!!

Answers

Let's say x to the shoter piece's length, since the longer one is 13 in longer, it's length has to be x+13 in. We know the sum of these pieces is equal to 47. So let's solve:
$x+x+13=47\n 2x+13=47\n 2x=47-13\n 2x=34\n x=\frac { 34 }{ 2 } \n x=17$
the shorter piece's length 'x' is 17 , so the longer piece's length 'x+13' is : $x+13\n 17+13=30$
