Answer:
126 was removed.
Step-by-step explanation:
The total before division took place was
Total = mean * 14
mean = 49
Total = 49 * 14
Total = 685
Now you subtract x from the total
685 - x
And divide by 13 [one number is missing]
(685 - x)/13
and the result = 43
(685 - x ) / 13 = 43 Multiply both sides by 13
685 - x = 43 * 13
685 - x = 559 Subtract 685 from both sides
- x = - 126 Multiply by - 1
x = 126
Answer:
n=(S/2)-u
Step-by-step explanation:
First, let's isolate 2n.
S-2u=2n
Let's divide both sides by 2.
(S/2)-u=n
n=(S/2)-u
Answer:
600
Step-by-step explanation:
V = s×s×s = s³
V = 10×10×10 =1,000
Surface area
6a² = 6(10²) =600
Two lines are parallel, means, they have the same slope.
the slop is 2/7 in this case
use point-slop form to write your equation: the given point is (7,3)
(y-3)=(2/7)(x-3)
Change it to slope-intercept form if needed: y=(2/7)x+(15/7)
