Question

Jeremiah writes the expression(40) - 1/10 times 40). to determine the number of questions answered correctly. Which is an equivalent expression?

Answer 1

$\bf 40-\cfrac{1}{10}\cdot 40\implies \stackrel{\mathbb{PEMDAS}}{40-\cfrac{40}{10}}\implies 40-4\implies 36$

Answer 2

Answer:

36

Step-by-step explanation:

we have the equation:

$40-\frac{1}{10}*40$

the fist thing we have to solve is the multiplication of 1/10 *40 since it has priority over the sum:

$40 -\frac{40}{10}$

Now we solve fot the quotient of  40/10

$= 40 - 4$

and finally, we have

$40 -\frac{1}{10}*40 = 36$
