Let's plug in the variables one by one.

6g - 2h

plug in 5 for g and 4 for h

6(5) - 2(4)

multiply

30 - 8

subtract

→ 22

20g

plug in 2 for g

20(2)

multiply

40

2(g + 1)

plug in 10 for g

2(10 + 1)

add

2(11)

multiply

→ 22

4g + 5h

plug in 1 for g and 4 for h

4(1) + 5(4)

multiply

4 + 20

add

24

Therefore, the answers that have a value of 22 are 6g - 2h and 2(g + 1)

Answer: 6g-2h when g=5 and h=4

and 2(g+1) when g=10 .

Step-by-step explanation:

1) 6g-2h  

when g=5 and h=4, then we have

6(5)-2(4)=30-8=22

2) 20 g  when g=2, we have

20(2)=40 ≠22

3) 2(g+1) when g=10 , we have

2(10+1)=2(11)=22

4) 4g+5h  when g=1 and h=4, we have

4(1)+5(4)=4+20=21≠22

Hence, the required answer is : 6g-2h when g=5 and h=4

and 2(g+1) when g=10 .

A cyclist estimates that he will bike 80 miles this week. He actually bikes 75.5 miles. What is the percent error of the cyclist
maw [93]

Answer:

<em>The percent error of the cyclist's estimate is 5.63%</em>

Step-by-step explanation:

<u>Percentages</u>

The cyclist estimates he will bike 80 miles this week, but he really bikes 75.5 miles.

The error of his estimate in miles can be calculated as the difference between his estimate and the real outcome:

Error = 80 miles - 75.5 miles = 4.5 miles

To calculate the error as a percent, we divide that quantity by the original estimate and multiply by 100%:

Error% = 4.5 / 80 * 100 = 5.625%

Rounding to the nearest hundredth:

The percent error of the cyclist's estimate is 5.63%
