The value of 7 in 26..74 is 0.7
The value of 7 in 37.596 is 7.
1/10 the value of 7 in 26.74 is 0.07 and 0.07 ≠ 7.
So, statement a) is incorrect.
1/100 the value of 7 in 26.74 is 0.007 and 0.007 ≠ 7.
So, statement c) is incorrect.
100 times the value of 7 in 26.74 is 70 and 70 ≠ 7.
So, statement d) is incorrect.
10 times the value of 7 in 26.74 is 7 and 7 = 7.
So, statement b) is correct and it correctly compares two values.

i know it i had that question
Answer:Brielle will run the half marathon race faster.Brielle will take 1 hour 44 minutes and 48 seconds, Joshua will take 2 hours 37 minutes and 12 seconds
Step-by-step explanation:
10 / 1.25 = 8
8 minutes a mile
18 / 1.5 = 12
12 minutes a mile
Brielle will run the half marathon race faster.
8 x 13.1 =104.8
12 x 13.1=157.2
104.8 - 60=
44.8
60 seconds x .8= 48
Brielle will take 1 hour 44 minutes and 48 seconds
157.2 - 120 = 37.2
60 seconds x .2 = 12
Joshua will take 2 hours 37 minutes and 12 seconds
Answer:
Im solving it.
Step-by-step explanation:
let the speed of plane in still air be x and that wind be y
therefore:
x+y=490
x-y=390
next we solve for the values of x and y, first we add the above equations. This will give us:
2x=880
x=880/2
x=440 miles per hour.
substituting the value of x in one of the equations and solving for y we get:
440+y=490
y=490-440
y=50 miles per hour
