Answer:
x=13
Step-by-step explanation:
Supplementary angles add to 180 degrees
x+167 = 180
Subtract 167 from each side
x+167-167= 180-167
x = 13
Answer:
A) 
, 
, 
, 
B) 2.53, 32.51, 514.37
Step-by-step explanation:
A) Multiply all of them to equal 80
1/2 = 40/80 (1 x 40) (2 x 40)
2/5 = 32/80 (2 x 16) (5 x 16)
3/8 = 30/80 (3 x 10) (8 x 10)
7/10 = 56/80 (7 x 8) (10 x 8)
B) Decimals are easy 1.10 < 1.20 since one is still greater than the other.
Answer:
31.5 $
Step-by-step explanation:
First lets se how much 1 pound of pasta costs in the store. We do this dividing the price for 8 pounds over those 8 pounds:

Answer:
18
Step-by-step explanation:
Number of pieces = Length of ribbon/Length of each piece
= (13½) ÷ (¾)
Convert the mixed number to an improper fraction
No. = (²⁷/₂) ÷ (¾)
Invert the proper fraction and change division to multiplication
No. = ²⁷/₂ × ⁴/₃
Cancel the 2s
No. = 27 × ⅔
Cancel the 3s
No. = 9 × 2
No. = 18
Sam can cut 18 pieces of ribbon.
