Answer:
I'm newbie here
Step-by-step explanation:
Elimination Method.
4x + 6/y = 15 → step 1
6x - 8/y = 14 → step 2
so,
4x + 6/y = 15 |×6|
6x - 8/y = 14 |×4|
24x + 6/y(6) = 90
24x - 8/y(4) = 56
24x + 36/y = 90
24x - 32/y = 56
____________ _
68/y = 34
68 = 34y
34y = 68
y = 2
subsitution y = 2 to..
4x + 6/y = 15
4x + 6/2 = 15
4x + 3 = 15
4x = 12
x = 3
So, for x is 3, and for y is 2
Divide 108 and 72 by twelve and you get 9 and 6 which all you have to do it multiply together
Answer:
14
Step-by-step explanation:
3(4)+2
12+2
14
The answer is 24 cm squared because to find the area of a rectangle you multiply the width by the height. 6 x 4= 24
4.05 - 3.24 = 0.81
(0.81 / 3.24)*100 = 25%
