Answer 1

Answer: He has made $72 this week

Step-by-step explanation:

We can set up the equation of Y = 9x where Y is how much he made and X is how many hours he worked.

We can simply plug in 8 hours for x to get Y=9(8) where Y=72.

Select all ratios equivalent to 1:3 A. 9:21 B. 5:15 C. 4:12

Answers

all of the answers would be correct/ equivalent to 1:3

It’s B, and C because 1 x 9 is 9 and 9 x 3 is 27 which proves its incorrect.

And 1 x 5 is 5 and 3 x 5 is 15 so its correct.

Lastly, 1 x 4 is 4 and 3 x 4 is 12 so that proves that this is correct.

janet bought a dress for $245. she recived a 15% discount vecause she is a loyal customer. in addition she recived another 10% off. calculate janets final bill

Answers

$187.42 !!!!!!!!!!!!!!!!!!!!

First turn 15% into a decimal= .15
Multiply .15 * 245 =$36.75 ok that’s the first discount!

Second discount is 10% so turn 10% into a decimal (by dividing your percentage by 100) = .10
Multiply .10*245= $24.50 <- that’s your second discount

Ok now take both those answers and subtract them from her original $245 bill.

245-(24.50+36.75)= $183.75

Her final bill is $183.75

To solve this all you have to do is multiply seven by the numerator. -3×7 = 21, so, -21/4 simplified would be -5 1/4. so D is correct.

Answer:

D) -5 1/4

Step-by-step explanation:

In this problem there is -3/4 foot change every year and you are trying to see how much changes over 7 years. That means you are multiply the 7 by -3/4. To do that you need to change the 7 into a fraction.

7= 7/1, now you are going to mulitpy the two fractions.

This line represents the numerators: 7 times -3= -21

This line represents the denominators: 1 times 4 = 4

Now that we know our fraction is -21/4 we simplify.

The simplest form you can get is -5 1/4.

I hope this helped, let me know if you have any questions!! :)

Answer:

The correct graph is A.

Step-by-step explanation:

-4x/5-13/5 ≥ -9

Multiply the entire equation by 5:

-4x-13 ≥ -45

Moving the -4x:

-13 ≥ -45+4x

Moving the -45:

32 ≥ 4x or 4x ≤ 32

So:

x ≤ 8

The correct graph is A.

The answer would be graph A that describes the solution set.
