In solving this type of problem always look for the person you don't have any information about in this case it's Eve therefore Eve is X, Justin has $7.50 more than Eve, therefore
X+$7.50 is Justin and Emma has $12 less than Justin, therefore subtract $12 from Justin X+$7.50-$12, since the total amount is $63 add all the numbers and equal them to $63.
x+7+x+7.5-12+ x=63
3x+3=63
3x=60
x=20
Plug in the x for each person
therefore Eve=$20
Justin=$20+$7.50= $27.50
Emma has $12 less than Justin therefore $15.50
Add all the money and it equals $63
Answer:
a) 166x.
Step-by-step explanation:
167x - x
= 166x.
Answer:
x < -12
General Formulas and Concepts:
<u>Pre-Algebra</u>
Distributive Property
Equality Properties
- Multiplication Property of Equality
- Division Property of Equality
- Addition Property of Equality
- Subtract Property of Equality
Step-by-step explanation:
<u>Step 1: Define</u>
16 < -2(x + 4)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -2: 16 < -2x - 8
- Add 8 to both sides: 24 < -2x
- Divide -2 on both sides: -12 > x
- Rewrite: x < -12
Here we see that any number <em>x</em> smaller than -12 would work as a solution to the inequality.
