Given the function f(x)=3x-5, for which value in the domain does f(x)=-38?

1 answer:

6 0

$f(x) = -38\\\\\implies 3x -5 = -38\\\\\implies 3x = -38 +5 \\\\\implies 3x = -33\\\\\implies x = -\dfrac{33}{3}\\\\\implies x = -11$

Describe 2 ways you could evaluate 37% of the sum of 27 3/5 and 15/9

miskamm [114]

First way is create an equation like this:
$0.37(27 \frac{3}{5}+ \frac{15}{9})$
and calculating it.
Second way is to find 37% of each number and then add it
$0.37*27 \frac{3}{5}$ + $0.37* \frac{15}{9}$
In both cases the result is 10.829

A total of 708 tickets were sold for the school play they were either adult tickets or student tickets there were 58 more studen

zhenek [66]

X = adult tickets and x+58 = student tickets

Create the equation from the problem.
x + x + 58 = 708

Combine like terms.
2x +58 = 708

Subtract 58.
2x = 650

Divide by 2.
x = 325

Therefore, your answer is:
there were 325 adult tickets sold.

(Adding 58 to that number will get you the student tickets sold which is 383 if they ask.)
