|n| = a <=> n = a or n= -a (for n and a are real numbers)
Answer:
8 units
Step-by-step explanation:
Since the y-coordinates are the same, you are only traveling horizontally, or from left to right. Therefore, you can find the length of the segment using a number line (like the one attached!) From -3 to 0 is 3 units, and from 0 to 5 is 5 units. Since 3 + 5 is 8, the segment is 8 units long.
Answer:
249 gallons of 7% butterfat milk and 83 gallons of 3% butterfat milk
Step-by-step explanation:
If x is the gallons of 7% butterfat milk, and y is the gallons of 3% butterfat milk, then:
x + y = 332
0.07x + 0.03y = 0.06(332)
Solve the system of equations using substitution:
0.07x + 0.03(332 − x) = 0.06(332)
0.07x + 9.96 − 0.03x = 19.92
0.04x = 9.96
x = 249
y = 332 − x
y = 83
You need 249 gallons of 7% butterfat milk and 83 gallons of 3% butterfat milk.
