Answer:
Elimination
x = 2
y = -2
Step-by-step explanation:
Elimination
2x + 4y = -4
2x - y = 6
Subtract the second equation from the first
5y = -10
Divide both sides by 5
y = -2
---------------------
Substitute for y = -2 in the second equation
2x - -2 = 6
2x + 2 = 6
subtract 2 from both sides
2x = 4
Divide both sides by 2
x = 2
Answer:
The answer is 7(x + 25)
Step-by-step explanation:
The question states 25 push-ups plus x amount of push-ups per day. To find how many push-ups per week, we multiply how many push-ups per day by 7 (a week).
60 min in one hour so 60+60+30=150.
150 divided 50 mins = 3 days (50+50+50=150)
