Devyn, Jessica, & Ashley earned a total of $228. Ashley earned $12 more than Jessica and Devyn earned $20 less than twice the amount Jessica earned. How much did each girl earn babysitting?

Answers

Answer:

Jesicaa=$59

Ashley=$71

Devyn=$98

Step-by-step explanation:

Let Jessica's earning be x:

$Jessica=x\n\nAshley=x+12\n\nDevyn=2x-20$

-Given that the total earnings for the three was$228. earnings per person is calculated as:

#Equate their earnings to the 228 to solve for x:

$x+(x+12)+(2x-20)=228\n\n4x-8=228\n\n4x=236\n\nx=59$

#Substitute for x in each earning equation to determine individual earnings:

$Jessica=x=59\n\nAshley=x+12=59+12=71\n\nDevyn=2x-20=59* 2-20=98$

Use an inequality symbol (<, >, =, ≤) to compare −3 + 7 _____ −10 − 2 A. > B. < C. = D. ≤

Answers

By using the concept of inequality, the solution for the correct inequality used between the given numbers is,

$(- 3 + 7 ) > (- 10 - 2)$

Used the concept of inequality, which states that,

A relation by which we can compare two or more mathematical expressions is called an inequality.

Given that,

Compare the numbers (- 3 + 7) and ( - 10 - 2).

Now, to compare the numbers we can solve each side,

(- 3 + 7) = - 3 + 7

= 7 - 3

= 4

(- 10 - 2) = - 10 - 2

= - 12

So, by the definition of positive and negative numbers, we get,

4 > - 12

As positive numbers are always greater than negative numbers.
