x is 9.
4x = 72.divide both sides by 4x = 18
72% of 90 = 80A percent is 1 part out of 100.1%isequalto1100or0.01.Proportions can be used to solve percent problems.partwhole=percent100solveThe part is 72.The percent is 90%.Let n represent the whole.Write a proportion to solve for n.72n=9010090n = 72 · 10090n = 7,20090n ÷ 90 = 7,200 ÷ 90n = 80
6s+2s=72 combine like terms 6s+2s=8s set equal to 72 8s=72 divide both sides by 8 to solve for "s". 8s=72 8 8 your answer is s= 72/8 which is 9.

It is: 2 times 36 = 72
X = 32
2/9=x/72 144=9x 16=x

n/18 = -72 we can solve for n by multiplying both sides by 18 which shows n = (-72)(18) = -1296
Inverse proportion implies xy = c where c is the constant of [inverse] proportionality. x = 2 and y = 36 implies xy = 72 = c So the relationship is xy = 72 Then, if x = 4, y = 72/x = 72/4 = 18
4x = 72.divide both sides by 4x = 18
You would formulate this problem X/100 * 150 = 72 and solve for X.
To find out what percent 72 is of 160, you can set up a proportion: 72 is to 160 as x is to 100. This can be written as 72/160 = x/100. Cross multiply to get 160x = 7200. Divide by 160 to solve for x, which equals 45. Therefore, 72 is 45% of 160.
To solve -58 - (-72), you first simplify it to -58 + 72. This equals 14, since adding 72 to -58 results in a positive number. Therefore, the answer is 14.
-12x = 72 Divde both sides by -12 to find the value of x: x = -6
To solve the expression, first calculate 100 - 62, which equals 38. Then, calculate 35 - 72, which equals -37. The results are 38 and -37, respectively.
