One <u>possible inequality</u> is:
299m+261j ≥ 1000.
Explanation:
m is the number of cups of milk and j is the number of cups of juice.
Each cup of milk contains 299 mg of calcium. This gives us 299m mg of calcium for m cups of milk drank.
Each cup of juice contains 261 mg of calcium. This gives us 261j mg of calcium for j cups of juice drank.
Together, this would be a total of 299m+261j mg of calcium.
We want to meet or exceed 1000 mg of calcium. This means we could have more than 1000 or equal to 1000; this gives us the inequality symbol "greater than or equal to":
299m+261j ≥ 1000
Answer:
10 x -6y = -76
-56 - 10x - y = -76
10x - 6y = -76 (-56) - (-76) = 20
-10 x -y = -20
10x - 6y = -76
-10x -y =-20
10x cancels
76 + 20 = 96
-7y = - 96
divide both sides by -7
y = 96/7
substitute into -10x - y = - 20
- 10x - 96/7 = - 20
96/7 is a fraction btw
= -10 x = - 20 + 96/7
-20 + 96/7
-10 x = -44/7
divide by - 10
x = 22/ 35 ( a fraction)
(x,y) = (22/ 35) ( 96/7)
Answer:
32
Step-by-step explanation:
Y - the money he still owes,
x - the number of months ( from x = 0 to x = 18 ):
y = 2,016 - 112 x
