Eric started at sea level. He descended 13.7 meters and then ascended 15.2 meters. Write an addition expression in the form Desc
Alex Ar [27]

The sum means that Eric is 3.3 m above sea level.

<h3>What is an addition expression?</h3>

This is a way of taking the sum of two or more expressions.

Given the following parameters

  • The distance while descending = -13.7 meters
  • The distance while ascending = +15.2 meters

An additional expression in the form of Descent + Ascent to represent this situation will be -13.7 + 15+ 2

<u>Calculate the sum:</u>

Sum =  -13.7 + 15+ 2Sum = 3.3 meters

Hence the sum means that Eric is 3.3 m above sea level.

1. The winner threw the ball 175 ft, so what we want to do now is we convert (175) ft into yd.

We already know that 1ft= 1/3 yd, so the distance in yd is:
175 ft* (1/3 yd/ 1 ft) = 58 1/3 yd.

The answer is A. 58 1/3 yards.

2. 75 min* (4.5 miles/ 15 min)= 22.5 miles.

The correct answer is D. 22.5

3. Let's say that there are 4 weeks in a month. There are 5 weekdays in a week, so the number of weekdays in a month is:
5 weekdays/ 1 week* (4 weeks/ 1 month)= 20 weekdays/ 1 month.

Alex runs 5.9 miles/ 1 weekday, so the number of miles he runs every month is:
(5.9 miles/ 1 weekday)* (20 weekdays/ 1 month)= 118 miles/ month.

The nearest number to 118 is 120, so the answer is D.120 miles

4. 10 sweaters to 8 shirts:

10:8= 10/8= 5/4

The answer is B. 5/4

Hope this would help~
