We can find the rate of each cyclist (assuming the rate is the amount they can travel in an hour) by dividing by 4 and then adding 6.

216/4 = 54

54 + 6 = 60.

The rate of each cyclist is 54 km/h and 60 k/ph.

How might you solve a problem that has both a fraction and a decimal in it

Anni [7]

Well, one way is to convert one of the numbers to the other. For example, if I have 3/5 and 0.5, I could convert 3/5 to a decimal. So, I would have 0.6 (3/5 converted to a decimal), and 0.5. Next, I would just add the two together to get my answer of 1.1

The ratio of females to total students in a mathematics class is 18 to 30. What fraction of the class is male? What percent is m

Vera_Pavlovna [14]

Answer:

2/5 or 40%

Step-by-step explanation:

total students=30

female students=18

That must mean, assuming the rest of the class is binary male=12

12/30=2/5 or 40% if you multiply by 20, then multiply by 100%

(2/5)*20=.40*100%=40%

Which of the following would not be the result of a substitution in the following system? 2x + y = 7 y - x = 1

telo118 [61]

Answer: Option C.

Step-by-step explanation:

A) The result of the substitution shown in Option A is obtained by solving for y from the first equation and substituting into the second equation:

$2x + y = 7\\y=7-2x$

$y - x = 1\\7-2x-x=1$

Therefore, this is a result of a substitution in the given system.

B) The result of the substitution shown in Option B is obtained by solving for y from the second equation and substituting into the first equation:

$y - x = 1$

$y=x+1$

$2x + y = 7\\2x + x + 1 = 7$

Therefore, this is a result of a substitution in the given system.

C) The result of the substitution shown in Option C is not a result of a substitution in the given system, because if you solve for x from the second equation and substitute into the first one, you get:

$y-x=1\\(-1)(-x)=(-y+1)(-1)\\x=y-1\\\\2(y - 1) + y = 7$
