Answer:
Step-by-step explanation:
C 40x^6
65 % ------------------ 23.4 items
100 % ----------------- x items
65 : 100 = 23.4 : x
65 x = 100 * 23.4
65 x = 2340
x = 2340 : 65
x = 36
Answer: there were 36 items on the test.
Answer:
B. 160 inches
Step-by-step explanation:
The wrapping paper would be the surface area of the box.
The surface area of a box is 2(h * W) + 2(h * L) + 2(W * L)
h = height
W = width
L = length
length x width x height
length = 5 in
width = 2 in
height = 10 in
2(10 * 2) + 2(10 * 5) + 2(2 * 5)
2(20) + 2(50) + 2(10)
40 + 100 + 20
160 inches
-1/8
4-2/-3/4 - - 1/2
Two negatives make a positive so,
4-2/-3/4 + 1/2 = 2/ -3/4 +2/4 =
2/ -1/4 , to divide a fraction you have to
Keep Change Flip
So,
-1/4 x 1/2 = -1/8
Here is the foil method, I hope it helped
