Nancy borrowed $150 from her parents to buy a video game system. She has agreed to pay them back $25 each week Which equation re
Zinaida [17]

Answer:

P = 150 - 25w

Step-by-step explanation:

Amount borrowed = $150

Repayment amount = $25 each week

P = amount Nancy owes

w = number of weeks

Amount Nancy owes = amount borrowed - repayment plan per week

P = 150 - 25w

During the first week of repayment: when w = 1

P = 150 - 25w

P = 150 - 25(1)

= 150 - 25

= 125

P = $125

Evaluate 3|x|+2x-1 when x = -5.
Savatey [412]

Answer:

4

Step-by-step explanation:

<em>To start off, we are going to input our x value into our expression.</em>

3|-5| + 2(-5) - 1

<em>Next, we are going to find the absolute value (always positive) of -5 and multiply 2 and -5.</em>

3(5) - 10 -1

<em>Now, we will multiply 3 and 5.</em>

15 - 10 -1

<em>Finally, we are going to combine our like terms (15, -10, and -1)</em>

4

<em>So! Our final answer for this expression is </em><u><em>4</em></u><em>!</em>

Hope this Helps! :)
