Answer:
Figure out what x is for both equations, then you can tell if the equations are the same
Step-by-step explanation:
1. 4x+1=9
x = 2
4 x 2= 8
2x+1=5
x = 2
2 x 2 = 4
4 does not = 9 so no.
Given length of a lap = 5/8 mile.
Number of laps Carin ran = 3 1/2 laps.
3 1/2 can be read as 3 and a half. In improper fractions, it can be written as
(3*2+1)/2 = 7/2 laps.
In order to find the total distance covered in 3 1/2 or 7/2 laps, we need to multiply length of a lap by total number of laps ran.
Therefore, total distance covered = 7/2 × 5/8.
=
Multiplying across, we get
= 
=
Let us convert 35/16 into mixed fractions.
On dividing 35 by 16, we get 2 quotient and 3 remainder.
So, the mixed fraction would be 2 3/16.
Therefore, she ran 2 3/16 miles in 3 1/2 laps.
The answer is b (the graph function does not form a straight line)
Answer and step-by-step explanation:
Becasue Manuel rode 8 miles in 40 minutes so he rode 1 mile in:
40 / 8 = 5 minutes
Because Eliza rode 5 miles in 30 minutes so she rode 1 mile in:
30/5 = 6 minutes
So manuel rode faster than eliza becasue:
- Manuel rode 1 mile in 5 mins
- Eliza rode 1 mile in 6 mins
So manuel rode faster than eliza
Hope this help you :3
