Answer:
36 and -1/8
Step-by-step explanation:
x^2 = 3^2 = 9 * 4 = 36
y^-3 = (-2)^-3 = -1/8
ask a question. will try to help and make it
Answer:
x+y=4+8=12
$12 for one of each
or if you mean indivually (the wording confused me)
$4 for child, $8 for adult
Step-by-step explanation:
x=adult
y=child
2x+10y=56
4x+5y=52
iin order to be able to subtract values and find x and y im going to multiply 4x+5y=52 by two and get 8x+10y=104
8x+10y=104
-2x+10y=56
6x=48 divide each side by 6
x=8
plug 8 back into an equation to find cost of y
2(8)+10y=56
-16 -16
10y=40
y=4
For this case we need the following skills:
Adding fractions // Subtracting fractions: necessary because operations with fractions need algebraic sum to clear unknowns.
Multiply fractions / Dividing fractions: Sometimes when doing common factor, you need to multiply and divide fractions.
Simplifying fractions: To rewrite the results, it is necessary to simplify fractions
Answer:
All mentioned skills are required.
