Answer:
x=45°
Step-by-step explanation:
The 160° plus the unlabeled angle to the left of it are supplementary, meaning when added they equal 180°. The unlabeled angle will therefore be 20°. The angle across from the 20° will also be 20°. 115° + 20° = 135°. Now all that is left on the top half is x.
180° - 135° = 45°
Answer:
h = 7
Step-by-step explanation:
18 = (h - 1) × 6 × 0.5
simplify:
18 = 3(h - 1)
distribute the 3:
18 = 3h - 3
add 3 to both sides:
3h = 21
divide by 3:
h = 7
Answer:
16
Step-by-step explanation:
x = number of footballs he can order
22*x + 13 (shipping fee) = 277
22x = 264 Subtract 13 from both sides
x = 16 Divide both sides by 22
Our solution is 16 footballs
Complete question :
A 48 inch board in to be cut into three pieces so that the second piece is twice as long as the first, and the third piece in 3 times as long as the first. If x represents the length of the first, find the lengths of all three
Answer:
Length of first piece = x = 8
Length of second = 2x = 8*2 = 16
Length of third = 3x = 8 * 3 = 24
Step-by-step explanation:
Let :
Length of first piece = x
Length of second = 2x
Length of third = 3x
The total lengtb of board = 48 inches
Hence,
First + second + third = 48
x + 2x + 3x = 48
6x = 48
x = 48 / 6
x = 8
Length of first piece = x = 8
Length of second = 2x = 8*2 = 16
Length of third = 3x = 8 * 3 = 24
