Answer:
A
Step-by-step explanation:
-x + 2y = 8
5x + 2y = -4
+ x. -2y. -8
6x = -12
÷6. ÷6
x = -2
5(-2) + 2y = -4
-10 + 2y = -4
+10. +10
2y = 6
÷2. ÷2
y = 3
1/4 = 0.25
8.25 + 0.25w = 10.25
0.25w = 10.25 - 8.25
0.25w = 2
w = 2 / 0.25
w = 8 <===
Divide 11 5/8 by 3
One way to do this:
Turn 11 5/8 from a mixed fraction into an improper fraction
11 5/8 = 93/8
93/8 x 1/3 = 93/24
