Answer: 1.3125 gallons
Step-by-step explanation: The machine pumps 2.1 gallons of water every 1.6 minutes. 1.6 minutes is 1.6x more than 1 minute. So, we have to divide 1.6 by 1.6. Next, we have to divide 2.1 by 1.6. We can make this a bit easier by multiplying both of them by 10 to get 21/16 which is 1.3125.
X+y=30
x-y=12
add them together
x+y=30
<u>x-y=12+</u>
2x+0y=42
2x=42
divide 2
x=21
subsitute
x+y=30
21+y=30
subtrat 21
y=9
number sare 21 and 9
Answer:
all equations will be like
y = a*x + b
a is just the slope and b is where the line intersects the y-axis (at x=0)
Answer:
4 feet
Step-by-step explanation:
the 9 part of the ratio relates to 18 feet , then
18 ÷ 9 = 2 feet ← value of 1 part of the ratio , then
2 parts = 2 × 2 feet = 4 feet ← length on scale drawing
