Avon Edwards worked 45.5 hours at $5 per hour. He made $100 in tips but no bonuses. Anything over 40 hours is paid time-and-a-ha
posledela

Answer:

1. D

2. B


Step-by-step explanation:

<u>Question 1:</u>

We can get Avon's earnings using the equation  W=HR+1.5VR+B+T

Where W is his earnings

HR is the regular hours (40 hours in this case)

V is overtime hours (hours over 40, 45.5 - 40 = 5.5 hours)

B is bonus (no bonus)

T is tips ( $100 tips, given)

and R is the rate (which is $5 per hour)


<em>Substituting the given info into the equation, we get:</em>

<em>W=HR+1.5VR+B+T\\W=(40)(5)+1.5(5.5)(5)+0+100\\W=341.25</em>


<em>So avon's earnings are $341.25</em>

<em>Answer choice D is right.</em>


<u>Question 2:</u>

The other employee needs to work x hours @ $15 per hour to equate or surpass $428. So we can set up the equation shown below and solve for x:

(15)(x)=428\\x=\frac{428}{15}\\x=28.53

Rounded to 1 decimal place, this is about 28.5 hours

Answer choice B is right.

Nadusha1986 [10]

Answer:

x^2 -10x+2

Step-by-step explanation:

(3x^2 - 11x - 4) – (x – 2) (2x + 3)

FOIL

(3x^2 - 11x - 4) – (2x^2-4x+3x-6)

Combine like terms

(3x^2 - 11x - 4) – (2x^2 -x-6)

Distribute the minus sign

3x^2 - 11x - 4 – 2x^2 +x+6

Combine like terms

x^2 -10x+2

How do you solve f (x)=-3 (x+2)+2
Allushta [10]

Answer:

−1/3y+−4/3

Step-by-step explanation:

We need to solve for x.

How? Easy! :D

Step one: Flip the equation. (In class we call it the 'flip-flop'.) When you do this, you should have your equation look like this:

−3x−4=y

Step two: Add 4 to both sides of the equation. When you do this step, your problem should look like this:

−3x−4+4=y+4

−3x=y+4

Step three: Divide both sides by -3.

-3x/-3 = y+4/-3.

Step four: Wrap-up. What the answer is.

x = -1/3y + -4/3

Final step: OUR ANSWER!

x = -1/3 + -4/3

Hope this helped! :D
