Answer:
195 mL of the 90% solution
Step-by-step explanation:
Let the number of mL of 90% mixture = x
Hence, our equation is
780mL × 15% + x mL × 90% = (780mL + x) 30%
117 + 0.9x = 234 + 0.3x
Collect like terms
0.9x - 0.3x = 234 - 117
0.6x = 117
x = 117/0.6
x = 195 mL
Therefore, You will need 195 mL of the 90% solution
Answer:
i have a f in math
Step-by-step explanation:
Answer:
let the number of ride ticket be x and that of the food ticket be y
x+y=32
1.50x+3.25y=90
y=32-x
1.50x+3.25(32-y)=90
1.50x+104-3.25y=90
-1.75x=90-104
-1.75x=-14
x=14/1.75
x=8
y=32-x
y=32-8=16
I would appreciate if my answer is chosen as a brainliest answer
