Answer:
The answer is 40 and I calculated it, it’s true
Step-by-step explanation:
I promise
2.75 i think,, 275 divided by 100=2.75
2x+y = -5. Solve this for y. We get y = -2x - 5. Find y^2: 4x^2 + 20x + 25. Substitute 4x^2 + 20x + 25 for y^2 in the first equation:
x^2 + 4x^2 + 20x + 25 = 25
Then 5x^2 + 20x = 0, so that x = 0. Subst. 0 for x in the 2nd eqn and find the value of y. Write your solutions as shown above: ( , ) and ( , ).

Answer:
The expression which represents the total number of miles he jogs in a week is 7 m ⇒ A
Step-by-step explanation:
Let us solve the question
∵ Dominic goes jogging every morning
∵ m represents the number of miles he jogs each day
→ That means he jogs m miles every day
∵ There are 7 days in a week
→ That means he jogs m miles every day for 7 days
∵ m + m + m + m + m + m + m = 7 × m
∴ He jogs in 1 week 7 × m miles
∴ He jogs 7 m miles in a week
The expression which represents the total number of miles he jogs in a week is 7 m
