a total of 25 times
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
(10-2)x180=1440 Degrees You first have to subtract 10 - 2 then multiply by 180
By the signs: 2+2(Add) 2-2(Subtract) +=add -=subtract
45 = 30 + m Subtract 30 from both sides: 15 = m

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.
You can subtract 2 from 21 a total of 10 times. This is because each time you subtract 2, you are left with 19, and you can repeat the process until you reach 1. Mathematically, this can be represented as 21 - 2 = 19, 19 - 2 = 17, and so on until you reach 1.
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
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.

M=4, Just subtract 9 from 13 to get m's value.
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
You would usually associate total with add. However getting a total can sometimes involve having to subtract something.
