1.) She has 8 apples and she wants to give 3/4 of them away so what you want to do is take (8 * 3/4) which is equals 24/4 which reduces down into 6, the answer is 6 apples.
2.) Multiple 1/5 mile by 4/1, which equals 4/5 mile total over four days. or 0.8 miles total.
Answer:
x= -1 and y =7
Step-by-step explanation:
To solve by elimination, multiply the entire first equation by 2 so that your x terms have the same coefficients.
2*(9x+2y=5) becomes 18x+4y=10.
Now stack and add each like term.
18x+4y=10
-18x-3y=-3
----------------------
0x +y = 7
y=7
Substitute y=7 into one of the original equations and solve for x.
9x +2(7) = 5
9x + 14 = 5
9x = -9
x=-1
I think neither of these proportions are right... are you sure you wrote it down correctly?
Answer:
8 , 5 , 5.785
Step-by-step explanation:
y^2 - x^3
first just plug in the numbers and you get
(4)^2 - (2)^3
Multiply
16-8 and this equals 8
x1 + x^3 - y^2
same pattern plug in the numbers
(3)^(1) + (3)^3 - (5)^2
multiply
3 + 27 - 25
P
E
M
D
Addition
Subtraction so do 3+27 first and you get
30 - 25 = 5
x^4 / x^3 plug it in
(6)^4 / (6)^3
multiply
1269 / 216
divide this and you get
5.875
