Answer:(7/8 - 4/5)^2 = 9
1600
= 0.005625
Step-by-step explanation:
Subtract: 7
8
- 4
5
= 7 · 5
8 · 5
- 4 · 8
5 · 8
= 35
40
- 32
40
= 35 - 32
40
= 3
40
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - seven eighths minus four fifths = three fortieths.
Exponentiation: the result of step No. 1 ^ 2 = (3
40
) ^ 2 = 32
402
= 9
1600
In words - three fortieths squared = nine one-thousand six-hundredths.
If you use a calculator you would get the answer 8. Because 8x8x8=512
Answer:
7
Step-by-step explanation:
Step 1:
18 - 5w + 7w - 4 = 28
Step 2:
14 + 2w = 28
Step 3:
2w = 14
Answer:
w = 7
Hope This Helps :)
We are given a line passes through the point (-2,5). The slope should have been given as well. Assuming that the slope is 2, we can determine the values of x and y for the points A and B.
The formula for the slope is
m = (y2 - y1)/(x2 - x1)
The slope between (-2,5) and A(x,3) is
2 = (3 - 5) / (x - (-2))
Solve for x
Use the same approach for the points (-2,5) and B(-2,y) to solve for y.
Answer:
-60 1/4 or -60.25
Step-by-step explanation:
you would subtract 30 1/4 by 90 1/2 to get the difference from the beginning to the end of the day
