Answer:
The expression showing how many more meters Mathieu ran than Edgar ran during that time is
.
Step-by-step explanation:
Edgar ran 'e' meters per second, and Mathieu ran 'm' meters per second. The boys ran for 't' seconds.
The expression
describes how many more meters Mathieu ran than Edgar ran during that time.
We can also use the expression
represent the same quantity.
We know that,

Distance covered by Edgar = te
Distance covered by Mathieu = tm
Difference in distance 
The expression showing how many more meters Mathieu ran than Edgar ran during that time is
.
Answer:
He lost 147.35 marks
Step-by-step explanation:
Take the total marks and subtract the marks he got to find the marks he lost
600-452.65= 147.35
Answer:
8 + 2x = 30
Step-by-step explanation:
Given,
The initial number of push-ups he does in each day = 8,
And, the number of push-ups, he increases per day = 2,
Let x be the number of days after he will reach his target of 30 push-ups,
Since, the number of push-ups she will increase in x days = 2x,
Thus, the number of push-ups she will do after x days = 8 + 2x,
⇒ 8 + 2x = 30, which is the required equation.
So in order to find the correct answer, we can just easily plug in the values to check which ordered pair matches the given inequality above. So based on my solutions, the correct answer would be the last pair.
<span> y − 2x ≤ 1
0 - 2(5)</span> ≤ 1
0-10 ≤ 1
-10 ≤ 1
Hope this answer helps.
Answer:
You have to multiply the denorminator to both sides in order to make x the subject :
