Answer:
Your answer is B
Step-by-step explanation:
6.14 Checkpoint: Systems of Linear Inequalities
I took the test.
We have the following variable:
x = The amount of orange juice
We have the following equation:
x + (× + 100) + 1/2 × = 1850
We clear x:
(5/2) x + 100 = 1850
(5/2) x = 1850 - 100
(5/2) x = 1750
x = 1750 / ((5/2))
x = 700 ml
pineapple juice = × + 100 = 700 + 100 = 800 mL
strawberry juice = 1/2 × = (1/2) 700 = 350 mL
The difference is:
800 - 350 = 450 mL
Answer:
The difference in the amounts of pineapple juice and strawberry juice martin combined was:
450 mL
Answer:
x=90/16,y=-150/16
Step-by-step explanation:
Simultaneous equation and we are to use elimination method
9x+y=30...(1)
6x-y=15..(2)
Add (1) and (2)
16x=15
Divide both sides by 16
x=15/16
Then substitute the value of x into (2)
6(15/16)-y=15
90/16-y=15
Substrate 15 from both sides
90/16-y-15=0
Add y to both sides
90/16-15=y
Lcm for only the left side which is 16
90-240/16=y
-150/16=y
Therefore x is 90/16 and y is -150/16
