Answer:
Streamers are $2.50 each
Balloons are $1.50 each
Step-by-step explanation:
Make a system of equations
3s + 15b = 30
2s + 4b = 11
Solve by elimination: multiply the top equation by 2 and the bottom equation by -3.
6s + 30b = 60
-6s -12b = -33
18b = 27
b = 1.5
Plug in 1.5 as b to find s
3s + 15(1.5) = 30
3s +22.5 = 30
3s = 7.5
s = 2.5
The streamers are $2.50 and the balloons are $1.50
Answer:
Step-by-step explanation:
18.4 + 8w = 6(-4.6 + 9w)
18.4 + 8w = (-4.6 * 6 + 9w * 6)
18.4 + 8w = (-27.6 + 54w)
18.4 + 8w + -54w = -27.6 + 54w + -54w
18.4 + -46w = -27.6 + 54w + -54w
18.4 + -18.4 + -46w = -27.6 + -18.4
Combine like terms: 18.4 + -18.4 = 0.0
0.0 + -46w = -27.6 + -18.4
-46w = -27.6 + -18.4
-27.6 + -18.4 = -46
-46w = -46
w = 1
Simplifying
w = 1
