Number of inches in 1 foot= 12
so,
number of inches in x feet= 12*x
17x+(1+x)
If x is the unknown variable then it can be: x-16
n/2 + 4
The expression that represents the product of 84 and b is 84b. In mathematical terms, when you multiply a number by a variable, you simply write the number next to the variable without any operation symbol in between. So, 84 multiplied by b is written as 84b.
answer: 5n
The expression is 9*x.
10n
40 + x
15 h
n/12. n=variable......stands for the number.
s + 9
n + 11
x-2
2n/5 or (2/5)*n
(x + 9)
17x+(1+x)
x + 138
