Sixty students got off a school bus. 30% of them were wearing college sweatshirts. How many were not wearing college sweatshirts?

42 students

Step-by-step explanation:

A percentage can be converted to a decimal. 30% -> 0.30.

Now multiply 60x0.30, which is 18.

So 18 were wearing sweatshirts. But that's not what we need.

Subtract 60-18, which is 42.

42 were not wearing sweatshirts.

f-1(x)= cube root of 19x squared/x

step-by-step explanation:

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
