Answer:
D (32, 10)
Step-by-step explanation:
30 - 5 - 5 - 5 - 5 = 10
0 + 8 + 8 + 8 + 8 = 32
Answer:
x = 1 y = 3
Step-by-step explanation:
4x - 1 = -3x + 6 Substitute the first equation for y in the second equation
+3x + 3x Add 3x to both sides
7x - 1 = 6
+ 1 +1 Add 1 to both sides
7x = 7 Divide both sides by 7
x = 1
Now plug this into the first equation
y = 4(1) - 1 Multiply
y = 4 - 1 Subtract
y = 3

Answer:
D. 211
Step-by-step explanation:
180-19=161
161+50=211
19+(211(x)-50)=180
Answer:
B)subtract
Step-by-step explanation:
Danielle would have to use the subtract operation to find out if she had enough money to buy the blouse after buying the CDs.
It would turn out like this:
$100 - $37 = $63
Now since Danielle knows that she has $63 dollars left, she has more than enough to buy the $53 blouse.
First, rewrite the equation, separating the terms inside the parentheses and multiplying each by the term preceding the parenthesis, remembering that the product of two negatives is a positive, and likewise (later) with quotients:
(-3 * 12) + (-3 * (-m)) = (-1 * m) + (-1 * (-8))
-36 + 3m = -m + 8
Subtract 8 from both sides:
(-36 - 8) + 3m = -m + (8 - 8)
-44 + 3m = -m
Divide each term by -m:
(-44 / (-m)) + (3m / (-m)) = -m / (-m)
(44 / m) - 3 = 1
Add 3 to both sides:
(44 / m) - 3 + 3 = 1 + 3
44 / m = 4
(is the answer jumping out at you yet?) :-)
Multiply both sides by m:
(44 / m) * m = 4m
44 = 4m
Divide both sides by 4:
44 / 4 = m
11 = m
Verify by substituting for m in the original equation:
-3(12 - m) = -1(m - 8)
-3(12 - 11) = -1(11 - 8)
-3(1) = -1(3)
-3 = -3
Voila! That's it!
