Answer:
x = ± 2
Step-by-step explanation:
Given
x² = 24 ( take the square root of both sides )
x = ±
= ±
= ±
×
= ± 2
The answer is A becasuse 6% of 100,000 is 6000 while through the other equations you would only get 4800
Answer:
B. (b x d) - c
Step-by-step explanation:
i. -(a x d) + b
= -(6 x
) + 8
= -3 + 8
= 5
ii. (b x d) - c
(8 x
) - 4
= 4 - 4
= 0
iii. 2(b x f) + a
= 2(8 x
) + 6
= 4 + 6
= 10
iv. (a x e) - c
= (6 x
) - 4
= 2 - 4
= -2
Thus, the expression which is equivalent to 0 is that of option B.
X/5 - 11 = -13
x/5 - 11 (+11) = -13 (+11)
x/5 = -2
x/5 (5) = -2(5)
x = -10
-10 is your number
hope this helps
Answer:
22
Step-by-step explanation:
Let X be the time for only a small drain, the work completed would be unity.
The small drain has been open for a total of 11 hours, one hour next to the large one, and 10 hours alone.
We have that large drainage can accomplish this in 2 hours.
We have the following system:
1/2 + 11 / x = 1
solving, we have:
11 / x = 1 - 1/2
11 / x = 1/2
x = 11 * 2
x = 22
I mean it would take a total of 22 hours for the small drain alone
