Answer:

x = √12

Step-by-step explanation:

Easy:

3x^2 = 36

Cancel out the 3 so it is only x^2; you can do this by dividing each side by 3 which gives you:

x^2 = 12

Square root the entire thing to get rid of the square and you get the answer

x = √12

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:

Question 1:

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)

Substituting the given info into the equation, we get:

$W=HR+1.5VR+B+T\\W=(40)(5)+1.5(5.5)(5)+0+100\\W=341.25$

So avon's earnings are $341.25

Answer choice D is right.

Question 2:

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.

A bank lent $200,500 for the development of two products. If the loan for priduct X was for $50,500 more than that for product Y

Kaylis [27]

Answer:

$75,000

Step-by-step explanation:

Let

x ----> amount lent for product X

y ---->amount lent for product Y

we know that

A bank lent $200,500 for the development of two products

$x+y=200,500$ ----> equation A

The loan for product X was for $50,500 more than that for product Y

$x=y+50,500$ ----> equation B

substitute equation B in equation A

$y+50,500+y=200,500$

solve for y

$2y=200,500-50,500\\2y=150,000\\y=\$75,000$
