Answer:
Step-by-step explanation:
Im pretty sure this 3d object is a prism but the formula for it should be V=B(base area) x h(height) so V= 120 x 10 = 1200in^3
Answer:
C. The attached
Step-by-step explanation:
Our total is 44 dollars. This means that the largest bar, our whole, should be 44.
-> This rules out option D
Now, 4 sweatshirts are being bought. This means the 44 dollars should be broken up into 4 different parts since they all "cost the same amount of money."
-> This rules out options A, C, and D.
This leaves us with the correct option of option C.
Have a nice day!

A. 3x + y = 13 → 15x + 5y = 65
x - 5y = 15 → x - 5y = 15
16x = 80
16 16
x = 5
x - 5y = 15
5 - 5y = 15
- 5 - 5
-5y = 10
-5 -5
y = -2
(x, y) = (5, -2)
b. 6x - y = 14
2x + y = 12
8x = 26
8 8
x = 3¹/₄
6x - y = 14
6(3¹/₄) - y = 14
19¹/₂ - y = 14
- 19¹/₂ - 19¹/₂
-y = -5¹/₂
-1 -1
y = 5¹/₂
(x, y) = (3¹/₄, 5¹/₂)
c. 3x - 4y = 22 → 15x - 20y = 110
2x + 5y = 7 → 8x + 20y = 28
23x = 138
23 23
x = 6
3x - 4y = 22
3(6) - 4y = 22
18 - 4y = 22
- 18 - 18
-4y = 4
-4 -4
y = -1
(x, y) = (6, -1)
Answer:
<em>c=</em><em>y+</em><em>7</em><em>/</em><em>d</em>
Step-by-step explanation:
y=cd-7
y+7=c×d
y+7/d=c
c=y+7/d
