Answer:
-2.45
Step-by-step explanation:
You are asked to EVALUATE 8.722÷(−3.56). Here you are dividing a positive number by a negative one, and so you expect that the result (quotient) will be negative.
Thus, 8.722÷(−3.56) becomes -8.722÷(3.56) = -2.45
Answer:
35% of 40 = 14; 40 - 14 = 26.
Step-by-step explanation:
The friend added the 35% (14) of 40 instead of subtracting, which is what we'd need to do in this situation since the question says 35% off.
Since they added the 14, it came out of $54.00 which is incorrect. The true value (with discount) = $26.00.
Answer: Y=-4x+7
Explanation:
Answer:
N = 4
Step-by-step explanation:
In the equation 2n + 7 = 15, we have to isolate the variable. But, before that, we have to get rid of anything else. Like the +7 in the equation. So we can subtract from each side.
2n + 7 = 15
Take out the +7 by subtracting 7 on both sides.
2n + 7 - 7 = 15 - 7
2n = 8
Now, to get rid of the 2 next to the n, we have to divide both sides by 2
2n/2 = 8/2
n=4
Answer:
t - (t x24%)
Step-by-step explanation:
Value of truck at the time of purchase was t dollars
value decreased by 24%
current value = t x 24%
t - (t x 24%).
current value = t -(t x 24%).
