Answer:
18 kilograms of drink A and 6 kilograms of drink B
Step-by-step explanation:
Let x equal the amount of Drink A
.04x + .08(24-x) = .05(24) Multiply through by 100 to clear the decimal
4x + 8(24-x) = 5(24)
4x + 192 - 8x = 120 Combine like terms
-4x + 192 = 120 Subtract 192 from both sides
-4x = -72 Divide both sides by -4
x = 18 This is the number of kilograms for drink A.
24-18= 6. This is the amount for Drink B
Answer:
C
Step-by-step explanation:
remember SOHCAHTOA
SOH is for sin
CAH is for cosin
TOA is for tan
line PS=14 so line QR=14
line PQ is your x value. so to solve, write out tan30=14/x
rewrite it so it now says x= 14/tan. type that in to your calculator and you get your answer
