Which statement about the best estimation strategy for this problem is correct? The Jackson family drove 490 miles each day for 9 days. They then flew 1,292 miles. How far did the Jackson family travel? A student answered 5,702 miles. A. 500 × 9 + 1,300 = The student's answer was reasonable. B. 500 ÷ 9 + 1,300 = The student's answer was not reasonable. C. 400 × 9 + 1,200 = The student's answer was not reasonable. D. 400 ÷ 9 + 1,200 = The student's answer was not reasonable.

Answers

If you would like to know which statement for this problem is correct, you can find this using the following steps:

490 miles * 9 days + 1,292 miles = 5,702 miles ... 500 miles * 9 days + 1,300 miles = 500 * 9 + 1,300 = 5,800 miles

The correct result would be: A. 500 × 9 + 1,300 = The student's answer was reasonable.

Percent of change 25 points to 50 points

Answers

percent change
first find change
then find as a percent out of original

percent mean parts out of 100 so x%=x/100

find change first

25 to 50 is a change of 25

now we do
change/original=x%
change/original=x/100
25/25=x/100
1=x/100
x=100


answer is 100% change

25 points to 50 points is a 100% change

100% of 25 = 25

25 + 25 = 50

100% is your answer

hope this helps

Use the distributive property to write 23y-(7x-2y)+x without parentheses.

Answers

Easy,

23y-(7x-2y)+x

There is an imaginary in front of the parentheses, making it,

23y-1(7x-2y)+x

Now, distribute the 1.

-1*7x= -7x
and
-1*-2y= 2y

Leaving your problem looking like...

23y-7x+2y+x

Combine your apples and oranges.....

25y-6x

Thus, your answer.
