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
First of all, this isn't an equation. There's no equal sign, so it's just an expression.
9x^2-27xy
9x(x-3y)
This is now factored. I pulled out the greatest common factor:)
30F because 30 C can be only sunny day
I think its shear, because that is the only one in which the shape actually changes shape and size
Answer: 687
Step-by-step explanation:
normally distributed
μ = 498
σ = 108
Top 4%
P(X > a) = 0.04
P(Z > a-498/108) = 0.04
Using the table attached, for the top 4%:
0.50 - 0.04 = 0.46
a-498/108 = 1.75
a-498 = 189
a = 687
The minimum score for the scholarship is 687.
