Answer:
4 (5/12). four and five-twelfths
Step-by-step explanation:
1/2 is the same as 2/4, so: 1 1/2 = 1 2/4
1 2/4 + 2 1/4 = 3 3/4
3/4 and 2/3 have a LCM or least common multiple of 12
4 x 3 = 12 and 3 x 4 =12; but whatever you do to the bottom you have to do to the top (3/4) turns into (9/12) and (2/3) turns into (8/12)
9/12 + 8/12 = 17/12 or 1 5/12 as a mixed number
3 + 1 5/12 = 4 5/12
I think a and c. I really don’t know tho
Hi, thank you for posting your question here at Brainly.
Since the hedge is surrounding the square base, the area of the base can be determined by subtracting the area of the base from the hedge.
A = pi*r^2 - (4x)^2
A = pi*(6x)^2 - (4x)^2
A = 2x^2*(3pi - 2)
I hope I was able to answer your question. Have a good day.
Answer:
3/7
Step-by-step explanation:
HCF of 21 and 49 = 7
21 / 49 = (21/7) / (49/7) = 21/7 *7/49 = 3 * 1/7 = 3/7
Answer:
D. (4, -3)
Step-by-step explanation:
You only need to find the value of y to select the correct answer, so if we're going to solve this system by elimination, we should choose to eliminate the x-variable.
We can subtract 3 times the first equation from 7 times the second to eliminate x. Those multipliers will give x-terms that will cancel.
3(7x +8y) -7(3x +2y) = 3(4) -7(6)
21x +24y -21x -14y = 12 -42 . . . . . eliminate parentheses
10y = -30 . . . . . . . . . . . . . . . . . . . . .collect terms
y = -3 . . . . matches choice D
