How many times can you subtract 2 from 50?
a total of 25 times
What is m 3m plus 10 equals 12- m?
3m + 10 = 12 - m add m to both sides: 4m + 10 = 12 subtract 10 from both sides: 4m = 2 divide both sides by 4: m = 2/4 = 1/2 or 0.5
What are the total degree of decagon?
(10-2)x180=1440 Degrees You first have to subtract 10 - 2 then multiply by 180
How do you know whether you should add or subtract the value of the two numbers?
By the signs: 2+2(Add) 2-2(Subtract) +=add -=subtract
What is the formula to find out the sum of first n odd numbers?
If you add numbers from 1 to n, the total is n(n+1)/2. How do we know that? Because you can add n to 1, and (n-1) to 2 and so on, so you have n/2 values each totalling n+1 (it works even if n is odd, as you would have a half total left in the end). Now, you want to add only the even integers, let's say from 1 to m. You can say that m is the same as 2n throughout. So the total of the first m even integers should be the same as twice the total of the first n integers, or n(n+1), and since we postulated that m=2n, the total is thus m/2(m/2+1). Same way, if we want to add only the odd numbers, we can say that m is 2n-1 (if we said 2n+1, we'd miss 1 and we'd start at 3). Or, we can simply use the even total equation abive and subtract 1 for each value added up (so that 2 becomes 1, 4 becomes 3 and so on) that is to say n value less. If you work up the algebra, you end up with an interesting property: the equation reduces to a very neat ((m+1)/2)^2, that is the total of all the odd number from 1 to 7 is (8/2) ^2 or 16. Try it.

What is 3m plus 2 equals 17?
3m+2=17 First, subtract 2 to get m on one side. 3m+2-2=17-2 3m=15 Divide by 3 to get m by itself. 3m/3=15/3 m=5 m equals 5.
What is m 3m plus 10 equals 12- m?
3m + 10 = 12 - m add m to both sides: 4m + 10 = 12 subtract 10 from both sides: 4m = 2 divide both sides by 4: m = 2/4 = 1/2 or 0.5
Max is 24 years older than his son Liam in two years Liam will be half as old as Max How old is Max now?
Equation 1: M = L + 24; Equation 2: M + 2 = 2(L + 2) Substitute M: L + 24 + 2 = 2L + 4 Subtract L from each side: 26 = L + 4 Subtract 4 from each side: 22 = L Max is 46 and Liam is 22; in 2 years Max will be 48 and Liam 24.
What are the total degree of decagon?
(10-2)x180=1440 Degrees You first have to subtract 10 - 2 then multiply by 180
What is the total displacement of a child who walks 4 m South 2 m North 5 m South and 5 m North?
2 m south
What does total mean add or subtract?
You would usually associate total with add. However getting a total can sometimes involve having to subtract something.
How do you solve m-9-13?
M=4, Just subtract 9 from 13 to get m's value.
Andrea walked 1 block north and than 2 blocks west how you determine her total displacement?
subtract 1 from 2
What 2 number you can mutiply to 80 but subtract to get -79?
mn = 80 m -n = -79 Substitute m - 80/m = -79 m^2 - 80 = -79m m^2 + 79m = 80 (NB Notice change of signs) Quadratic Eq'n m = { - 79 +/- sqrt[)79)^2 - 4(1)(-80)}] / 2(1) m = { - 79 +/- sqrt[6241 + 320}]/ 2 m = { -79 +/- sqrt[6561]} / 2 m = { - 79 +/- 81}/2 m = -160 / 2 = -80 or m = 2/2 = 1 Hence n = 1 + 79 = 80
How do you find the total degree in a polygon?
The formula is M=180 times (n-2), where M is the total degree measure in the polygon and n is the number of sides. For example, in a hexagon, n is six, so M=180x(6-2), M=180x4 M=720, so there are 720 total degrees in a hexagon.
What is MC on a calculator?
MR is Memory Recall MC is Memory Clear M+ is Memory add M- is Memory subtract These are used to add and subtract the answers to multi-step equations so you can do the small steps with the calculator, then store, change or recall the total as needed. You might add a long string of numbers in groups this way. Or you can do all operations in one parenthesis, then just store the total of each.
