Answer:

40 minutes.

Step-by-step explanation:

Hi there! I'm glad I was able to help you solve this problem!

We are given that Alison does 8 math problems in TWO minutes.

Considering this, we can conclude that Alison can do FOUR math problems in ONE minute. (That's pretty impressive, if you ask me!)

To recap how I solved this, I put 8/2 in simplest form, which left me with 4/1.

NOTE: Per 1 minute, Alison completes 4 problems.

By doing mental math myself, I concluded that my answer was 40 minutes for Alison to complete 160 math problems. I had to check it, though!

The GCF (Greatest Common Factor) of 160 and 40 was 40.

I divided both terms by the GCF, which is again 40.

160 ÷ 40 = 4

40 ÷ 40 = 1

This brings us back to our improper fraction in simplest form 4/1!

Therefore, Alison will take about 40 minutes to complete a set of 160 problems.

I hope this helped you out! Comment below if I can help you with anything else! :)

Solve the system by substitution.<br> x – 4y = -8<br> 5у – 1 = x<br> Submit Answer
Vikki [24]

Answer:

y = -7 and x = -36

Step-by-step explanation:

x - 4y = -8

5y - 1 = x

→ Substitute 5y - 1 into x - 4y = -8

5y - 1 - 4y = -8

→ Simplify

y - 1 = -8

→ Add 1 to both sides

y = -7

→ Substitute y = -7 into 5y - 1

( 5 × -7 ) - 1 = -36

Larisa earns $7 per hour.she worked 40 hours at the regular rate, 3 hours at time and half, and 6 hours at double time.
VARVARA [1.3K]

Answer:

$6.07/hr. if I understand the question properly.  See below.

Step-by-step explanation:

I don't see the question, but will assume we want to find Larisa's base pay.  The $7/hr given is the average for the work sequence noted in the problem.  If this is incorrect, ignore the answer.

==================================

Let x be Larisa's base salary.  We are told, I think, that in one stretch of time Larisa earned an average of $7/hour.  That was composed of:

<u>Hours</u>  <u>Rate($/hr)</u>

  40           x

    3        1.5x

<u>     6    </u>     2x

  49

Her total income over this period would be:

40x +3(1.5x) + 6(2x)  [The hours worked times the pay rate for each period]

Her average income per hour would be:

(40x +3(1.5x) + 6(2x))/49

which we are told is $7/hr.

(40x +3(1.5x) + 6(2x))/49 = 7

40x + 4.5x + 12x = 343

56.5x = 343

x = $6.07/hr
