Answer:
Step-by-step explanation:
2/5min=24 sec
5 min=300 sec
total=324 seconds
the water decreased 100-19=81 degrees
81/324=0.25 degrees/second
the change in temperature was 0.25 degrees per second
we will multiply by 60
15 degrees per minute
eliminating y
x - y = -5
3x + y = 1
________ +
4x = -4
x = -1
eliminating x
• x - y = -5 ....... (x3)
3x + y = 1 ....... (x1)
• 3x - 3y = -15
3x + y =1
___________ -
-4y = -16
y = 4
A. (-1, 4)
Answer:
The mom is 5 feet 3 inches
Step-by-step explanation:
<u>Step 1: Make an equation</u>
m = 1 3/4 * 3

m = 7/4 * 3
m = 21/4
m = 5.25
<em>m = 5 feet 3 inches</em>
