Answer:
Yes, the estimate given is reasonable.
Explanation:
If we do the maths of this question with estimates, we can guess that the average mileage be about 26 or nearly 25 for easy calculation.
If each friend drives between 57 and 63, then the average be about 60.
So for a person with a mileage of 25 to go nearly 60 miles, he would have to use nearly 2.5 gallons. Therefore, for the 3 friends, it would be 2.5*3 = 7.5 nearly 7 gallons.
Thus his estimation was reasonable.
Answer: Keep the compass needle on A, and stretch the compass width to B
Step-by-step explanation: If AB is also a line segment, then the answer is: Keep the compass needle on A, and stretch the compass width to B.
Add 1/4 to both sides to get T=-2/4
28 1/2=57/2
4 3/4=19/4
57/2 ÷ 19/4
57/2 × 4/19
3/1 × 2/1 [reduced]

6 packages of 4 3/4 ounces in a box of 28 1/2 ounces
<span>To determine the number of lawns he needs to mow to earn the desired money, Eli could perform a simple addition problem, adding $21 per lawn until he reached his goal number. This equation would be: 21 + 21 = 42 + 21 = 63 + 21 = 84 + 21 = 105 + 21 = 126 + 21 = 147 + 21 = 168 + 21 = 189 + 21 = 210 + 21 = 231 + 21 = 252. However, a better way would be to divide the desired amount by the cost per lawn and round to the nearest whole number. That equation is 235 / 21 = 12 lawns.</span>
