Answer:
6 hot dogs, 2 drinks
Step-by-step explanation:
let y = number of hot dogs
let x = number of drinks
system:
y = 3x
4.5y + 2.25x = 31.50 (standard form: y = -1/2x + 7)
if you graph the system, lines intersect at (2, 6)
The answer is -25 i just took the test/quiz
Answer:
54.67 cm²
Step-by-step explanation:
Given that the two sides of Δ ABC are 8.2 cm and 13.5 cm and the angle included by those sides is 81°.
Let, b = 8.2 cm and c = 13.5 cm and ∠ A = 81°
Hence, area of triangle ABC, Δ = 
⇒ Δ = 
⇒ Δ = 
⇒ Δ = 54.67 cm² (Answer)
Answer:
The answer would be 3y + 27
Step-by-step explanation:
Distributing the 3 to y would multiply it together making it 3y. Distributing the 3 to the 9 would be 3x9 and be 27.
Answer:
The answer would be (x+7)(x-7).
Step-by-step explanation:
(49 is a perfect square, which would be 7)
