1. Since it's m - 7 you would have 7 to both sides so you would in fact have m < 13. If you double check your answer, you see that if m is say 12 (because 12 is obviously less than 13), 12 - 7 < 6
2. Again, use the same process on this problem as the first one. Add 8 to each sides because it's you're subtracting 8 from n. So you end up with n > 13. Check your answer. Say n is 14. 14 - 8 > 5
3. This one is different because you are adding 5 to p. So in order to get p by itself, you need to subtract 5 from both sides. p < 5. Say p is 4, 4 + 5 < 10.
When working with problems like these, you need to isolate the variable on one side and get it by itself.
Answer:
Are you cheating?
Step-by-step explanation:
Step-by-step explanation:
he has 900-230 = 670 more push-ups to do in the remaining 20 days.
so, he has to do every day
670/20 = 67/2 = 33.5 push-ups.
fractions of push-ups don't make sense.
we cannot say, he has to do at least 33 per day, because then he might come short in the end (if he sticks to the low limit) .
so, we have to say he has to do more than 33 or at least 34 push-ups per day to be sure he will at least reach his goal.
p > 33
or
p >= 34
both should be correct in the context of using only whole numbers.
bur in case of doubt I would pick p >= 34.
If AB = BC then set up the equation 3x - 4 = 5x - 10
Subtract 3x.
-4 = 2x - 10
Add 10.
6 = 2x
Divide by 2.
3 = x
AB is 3x - 4 so
3(3) - 4
9 - 4
5.
AB = 5
If AB is not equal to BC then this is not solvable.
But if they are I am sure AB = 5.
Hope this helps
