Remember the order of operations rules. PEMDAS: parentheses first, then exponents, then multiplication, then division, then addition and subtraction is last.

= 42+6⋅52−33÷32
multiply first

= 42 + (6*52) - 33 ÷ 32
= 42 + 312 - 33 ÷ 32
division second

= 42 + 312 - 1.03125
addition next

= 354 - 1.03125
subtraction last

= 352.96875

ANSWER: 352.96875 (*if rounding, answer is 353)

Hope this helps! :)

Question 4(Multiple Choice Worth 2 points)

Answer:

The coefficient of variable term y is -1

Step-by-step explanation:

We have an expression given in the question that is:

6 - y + 3

We have to find the coefficient of the variable term.

In mathematics, variable can be defined as any term which is to be measured. For example in the given expression, y is the variable because its value is unknown yet and it has to be measured.

Coefficients are the number the multiply the variable

For example

In 2x, x is the variable and 2 is the coefficient.

Now in the given expression, we have

6 - y + 3

6 + (-1)(y) + 3

So considering (-1)(y), the variable is y while its coefficent is -1
