Well, I'm not going to give you the answers, but first erase the "(variable) =". They already gave you the value of the variables, so you just have to multiply the variables, like for example, "7/8 × c, c = 6". It's telling you to multiply 7/8 by 6. The rest goes for everything and in the future, instead of writing it as 7/8 × c, it'll say 7/8c.

So yeah, just multiply the number by the variable, which already has a given value.

Answer:

B) Angle 2 and Angle 3

Step-by-step explanation:

Angle 2 and Angle 3 are equal since they're vertical angles and aren't supplementary

Angle 7 and 8 are supplementary

Angle 1 and 7 are supplementary

Honestly, i have no clue with angle 4 and angle 4. I just know that vertical angles aren't supplementary because they're equal to each other so I'll assume this is the case as well.

l x w x h = 2,197

If l=w=h then it is a perfect cube.

The cube root of 2,197 is 13

Therefore, the cube is 13 x 13 x 13 inches.

Can someone help me with this?

Answer:

Step-by-step explanation:

We first need to figure out how much money Jackie has since Pilar has the same amount of money, but in different coins. Jackie has 24 dimes and 13 quarters, so the amount of money is $2.40 + $3.25 = $5.65; therefore, Pilar has $5.65 also. In order to determine how many nickels and quarters Pilar has, we have to have a system of equations. It's up to us to write the equations we need to solve this. The first equation has to do with the NUMBER of coins Pilar has, the second has to do with the VALUE of each coin. We know that Pilar has only nickels and quarters and that she has a total of 53 coins. So the NUMBER equation is

n + q = 53

The VALUE equation relates how much each coin is worth to the total amount of money it equals:

.05n + .25q = 5.65.

Go back to the first equation and solve it for either n or q. I solved it for n:

n = 53 - q

Plug this into the second equation in place of n now to get:

.05(53 - q) + .25q = 5.65 and

2.65- .05q + .25q = 5.65 and

.20q = 3 so

q = 15. This means that there are 15 quarters. If there are 15 quarters, then there are

n + 15 = 53 nickels and

n = 38 nickels.

In math class the girl to boy ratio is 8 to 6 if there are 24 girls in the class , how many boys are there ?

Volgvan

Answer: The required number of boys in the class is 18.

Step-by-step explanation: Given that in math class, the girl to boy ratio is 8 to 6 and there are 24 girls in the class.

We are to find the number of boys in the class.

Let 8x and 6x represents the number of girls and boys in the class.

Then, according to the given information, we have

$8x=24\\\\\Rightarrow x=\dfrac{24}{8}\\\\\Rightarrow x=3.$

Therefore, the number of boys in the class is given by

$6x=6\times3=18.$

Thus, the required number of boys in the class is 18.
