Answer:

1.) C

Because 18/27 and 6/9 both reduce to 2/3, while 12/15 does not.


2.) C

Because it's asking for the ratio of CPR training to first aid training. It's a trick question because though it mentions first aid first, and CPR training last, it's asking for you to find the reverse.

3.) C

Because to find the unit rate, the cost for each DVD, you divide 25.20, the total price, by 4, the number of DVD's purchased.

4.) B

Same thing as above.

5.) C

Same thing as the other two, but this time, you multiply the number you got from dividing the rate by time, by 2 since it wants to know how far Sheila went in 2 minutes.

6.) I cannot see the lower answer options but I believe the answer is 54.

He subtracted 130 from his account, added 240, then subtracted 56.

7.) B

Because 10/4 reduces to 5/2.

8.) C

Because 5/8 of 64 is 40, and 1/4 of 40 is 10. However, it wants to know how many players have classical solos, so look at the other 3/4 of 40; it is 30.

9.) I'm going to be honest, I dont know this one. Maybe post it seperately on Brainly, I'm sure someone will know what to do!


Have a good night and please do not be stressed out. Just truly do your best in math, and I promise you that if you care about it and work to understand it, it will all pay off in the end and you'll be astounded that you were ever confused! :)

Good luck!!!!

Why did the Republicans in Congress feel that the Fourteenth Amendment was necessary?
Lunna [17]
They did it to protect the civil rights act from being overturned by the south. That is not one of the choices but that is what happened. They made it so that everyone is equal and that whites would not judge blacks. So I would say that C. is the correct answer.

Dave sold 60 general and reserved tickets for a concert. He sold general tickets for $10 each and reserved tickets for $15 each
swat32

Answer:

The system is of equations is:

\left\{        \begin{array}{ll}            10g+15r=725 & \quad  \\            g+r=60 & \quad         \end{array}    \right.

Where g is the amount of general tickets and r is the amount of reserve tickets.

35 general tickets and 25 reserve tickets were sold.

Step-by-step explanation:

Let general tickets be represented by g and reserved tickets be represented by r.

Each general ticket sells for $10 each and reserved tickets $15 each. Dave collected a total of $725. Thus:

10g+15r=725

And a total of 60 tickets were sold. Hence:

g+r=60

Our system of equations is:

\left\{        \begin{array}{ll}            10g+15r=725 & \quad  \\            g+r=60 & \quad         \end{array}    \right.

We can solve by substitution. First, divide both sides of the first equation by 5:

2g+3r=145

Next, we can subtract a variable (r in this case) from the second equation:

g=60-r

Substitute:

2(60-r)+3r=145

Distribute:

120-2r+3r=145

Simplify:

120+r=145

Subtract:

r=25

Using the previous equation:

g=60-r

Substitute and evaluate:

g=60-(25)=35

So, 35 general tickets and 25 reserve tickets were sold.

Kyle notices that the number of likes he receives each day on his social media page is a function. He decides to create a graph
12345 [234]

Answer:

B) y=12x

Step-by-step explanation:

We are given with the coordinates (0,0) , (1,12) \ and \ (2,24)

Where x represents the number of days.

y represents the number of likes she got.

To model the equation using Kyle's data we find the slope using the given coordinate.

Let us say (0,0) \ as \ (x1 , y1) and (1,12) \ as \ (x2,y2)

Slope (m) formula ,  m=\frac{(y2-y1)}{(x2-x1)}

Plug in the above points now, we get

m=\frac{(12-0)}{(1-0)} =\frac{12}{1} =12

Now we use the point-slope formula, (y-1)= m(x-x1)

Plugging the corresponding values.

     (y-0)= 12(x-0)\\y=12x

Thus option is B is the correct answer.
