Answer:
1000
Step-by-step explanation:
-4x + 8y = 2
-4x + 4x + 8y = 2 + 4x
8y = 4x + 2
8 8
y = ¹/₂x + ¹/₄
Answer:
112
Step-by-step explanation:
180 - 40 - 28 = 112
L = 2 + .5W
2L + 2W = 40
SOLVING (if needed)
Substitute 2 + .5w in for l in the second equation and solve for w.
2(2 + .5w) + 2w = 40
4 + w + 2w = 40
Combine like terms and subtract 4 from both sides
3w = 36
Divide both sides by 3
w = 12 in.
l = 2 + .5w
l = 2 + .5(12)
l = 8 in.
Answer:
-9
Step-by-step explanation:
36 ÷ (1 - |2 - 7|) =
Start with the calculation inside the absolute value.
= 36 ÷ (1 - |-5|)
Now take the absolute value of -5 which is 5.
= 36 ÷ (1 - 5)
Do the operation inside the parentheses, 1 - 5 = -4.
= 36 ÷ (-4)
Finally divide. Remember that positive divided by negative is negative.
= -9
