Answer:

  n = 4

Step-by-step explanation:

Put the given values in the equation and solve for n.

  9 = 4n -7

  16 = 4n . . . . . . add 7

  4 = n . . . . . . . . divide by 4

The value of n is 4 so that m(4) = 9.

What is the answer the proprtion m+12/9m=5/9
Delvig [45]
(m + 12) / 9m = 5 / 9
cross multiply
(5)(9m) = 9(m + 12)
45m = 9m + 108
45m - 9m = 108
36m = 108
m = 108/36
m = 3 <==

Because the two angles add up to equal 90, you would make an equation set to equal 90. On the other end you add the measures of your angles together because they are adding up to equal 90. This would look like 2x+5+35=90 and you solve from here. Add like terms making it 2x+40=90 then you subtract 40 from both sides making it 2x=50 and then divide by 2 on both sides which leaves you with x=25.

What's 80÷7 I need this answer fast thank you it's for 65 points
klemol [59]
In order to solve this, we must find out how many times 7 goes into 80. We can do this by either subtracting individual 7s from 80, or by adding 7s together until we cannot add another without going past 80.

For this answer, I will use the addition method.

7 + 7 = 14

14 + 7 = 21

21 + 7 = 28

28 + 7 = 35

35 + 7 = 42

42 + 7 = 49

49 + 7 = 56

56 + 7 = 63

63 + 7 = 70

70 + 7 = 77

From 77, we cannot add another 7 to it without going over 80, since 77 + 7 = 84.

So, let's count the sevens that we have added up so far, and when we do, we can see that there are 11 of them, adding up to 77.
So 7 goes into 80 11 times. Now, let's find the remainder...

To find the remainder, you just need to subtract the final added number from the number you are dividing from.

80 - 77 = 3

80 / 7 = 11, remainder 3
Hope that helped! =)
