Answer:
$3.61
Step-by-step explanation:
let p represent pizza and d represent drink, then
8p + 6d = 39.5 → (1)
5p + 7d = 30.44 → (2)
Multiplying (1) by 7 and (2) by - 6 and adding will eliminate d
56p + 42d = 276.5 → (3)
- 30p - 42d = - 182.64 → (4)
Add (3) and (4) term by term
(56p - 30p) + (42d- 42d) = (276.5 - 182.64), that is
26p = 93.86 ( divide both sides by 26 )
p = 3.61
That is a slice of pizza costs $3.61
Answer:
9, 9√2
Step-by-step explanation:
The ratios of side lengths in a 45°-45°-90° triangle are ...
1 : 1 : √2
The other leg is the same as the first, and the hypotenuse is √2 times that.
The other sides are 9 and 9√2.
50 + (3x - y) = x + (2x - 16). Combine like terms to change the 2nd part to get 3x - 16. 50 + 3x-y = 3x - 16. Subtract 3x from both sides to get 50 - y = -16. Subtract 50 from both sides to get -y = - 66, or y = 66. 90 - 50 = 40 = 3x - 66. Add 66 to both sides to get 3x = 106, or x = 35 1/3.
