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
Since the horizontal lines are parallel, we know from similar figures that the ratios are proportional.
when
24/x=36/12, or
24 36
-- = ---
x 12
We divide the product of diagonals with numbers (24*12) by the number across from x (36) to get the value of x, i.e.
x=(24*12)/36=288/36=8
Answer:
2., an irrational number
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
Answer:
x= -1
Step-by-step explanation
First move the variables to the left and change it's sign
(-6+x-2x=-5)
Then combine like terms
(-6-x=-5)
Then move the -6 to the right and combine it with the -5
(-x=-5+6)
(-x=1)
Lastly change the signs by dividing by 1
(x=-1)
