Answer:
D look up the question on quizlet to get all of your answers to your lesson :)
Step-by-step explanation:
<span>a/b = 3/5 ----- a = (3b)/5
a + b = 136 --- (3b)/5 + b = 136
3b + 5b = 680
8b = 680
b = 85
a = (3b)/5 = (3 * 85)/5 = 51
a = 85 and b = 51</span>
Answer:
lemonade = 11
Step-by-step explanation:
let p = pink lemonade
let t = sweet tea
create a system of equations -- one with quantity, one with associate costs
p + t = 21
2.5p + 4t = 67.5
substitution method: let t = 21 - p
2.5p + 4(21 - p) = 67.5
2.5p + 84 - 4p = 67.5
-1.5 p = -16.5
p = 11
t = 21 - 11
t = 10
Answer:
40 bars
Step-by-step explanation:
Where x = Number of bars purchased by each team
We solve this question by equating both Equations from Company A to Company B
Company A = Company B
0.75x = 10 + 0.50x
Collect like terms
0.75x - 0.50x = 10
0.25x = 10
x = 10/0.25
x = 40 bars
Hence, each team need to purchase 40 bars from each company
