Answer:
Use estimation
Step-by-step explanation:
A) 99 + 54
estimate that 99 is 100
estimate that 54 is 55
Add 100 and 55 together
100 + 55 = 155
Remember that you added 1 to 99 and 1 to 55
So you must subtract 2 from 155
155 - 2 = 153
Your answer is 153.
B) 244 - 99
estimate that 244 is 245
estimate that 99 is 100
Add 245 and 100 together
245 + 100 = 345
Remember that you added 1 to 245 and 1 to 99
So you must subtract 2 from 345
345 - 2 = 343
Your answer is 343.

Answer:
I guess the correct answer is 116 cm
Step-by-step explanation:
Simple...
you have: If this cable installer charges $42.50 per hour plus a fixed $45 service charge..then set your equation..using-->>
y=mx+b
How much would the cable installer charge for 5 hours?
y=42.50(5)+45
y=212.50+45
y=$257.50
Thus, your answer.
<h3>
Answer: y = 4</h3>
Explanation:
Line L is the horizontal line. Any point on this line has y coordinate y = 4, so the equation is simply y = 4.
You could say the equation is y = 0x+4, which shows the slope is 0. But I think y = 4 is the better answer.
