a + 18 = 90 is a linear equation in one variable.
Adding both sides by -18, we get
a + 18 - 18 = 90 - 18
a = 90 - 18 = 72
-86
90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12
90 + 90 + 60 = 240
54 + 560 + 90 = 704
4x + 4 + 5x - 22 = 90 combined like terms 9x - 18 = 90 +18 +18 9x = 108 /9 /9 divide by 9 on both sides x = 12 plug in and check (4 * 12) + 4 + (5 * 12) - 22 = 90 48 + 4 + 60 -22 = 90 90 = 90
-86
90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12
90 + 90 + 60 = 240

The answer is .90. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
90 minus 75 =15 therefore 15 + 75 = 90
54 + 560 + 90 = 704
To solve for tan x degree 90 you do a few things. First, if x equals 90, then this equals 1.5597 radian or 89.36 degrees. This is the easiest way to solve tan x degree 90.
6 + 90 = 96
To find the missing number in the denominator of the fraction, you can set up the equation 90/x = 18, where x is the missing number. To solve for x, you would multiply both sides by x to get rid of the denominator, giving you 90 = 18x. Then, divide both sides by 18 to solve for x, which equals 5. Therefore, the fraction is 90/5 = 18.
