Answer: r = 7

Step-by-step explanation:

Subtract 12 from both sides to isolate the r variable. You have -42 = -6r. Divide both sides by -6 to get r by itself and you get r = 7. Verify by substituting 7 as the r value and solving the equation.

Answer:

r=7

Step-by-step explanation:

First subtract 12 from both sides

Now you have -42=-6r

Next divide each side by -6

Now you have 7=r

And that is your answer

A sixth-grade class went on a field trip. There were 24 chaperones and 84 students on the trip. What is the ratio of chaperones
Morgarella [4.7K]

Answer:

24 : 84 = 2 : 7

Step-by-step explanation:

We can simplify the ratio 24 : 84 by dividing both terms by the greatest common factor (GCF).

The GCF of 24 and 84 is 12.

Divide both terms by 12.

24 ÷ 12 = 2

84 ÷ 12 = 7

Therefore:

24 : 84 = 2 : 7

A local zoo has flamingos and elephants in one exhibit. There are 16 animals in the exhibit, and the animals have a risk of 52 l
Advocard [28]

Answer:

We have 6 flamy and 10 Elephants

Step-by-step explanation:

A local zoo has flamingos and elephants in one exhibit.

Flamingos have 2 legs

Elephants have 4 legs

Let the number of

Flamingos = x

Elephants = y

There are 16 animals in the exhibit

= x + y = 16..... Equation 1

x = 16 - y

The animals have a risk of 52 legs.

2 × x + 4 × y = 52

2x + 4y = 52..... Equation 2

We substitute 16 - y for x in Equation 2

2(16 - y) + 4y = 52

32 - 2y + 4y = 52

- 2y + 4y = 52 - 32

2y = 20

y = 20/2

y = 10

Solving for x

x = 16 - y

x = 16 - 10

x = 6

Hence, we have

Flamingos = x = 6 flamingos

Elephants = y = 10 Elephants

Find an exponential function that fits the information (hint: putting them in a table may help you see).
Vilka [71]

Answer:

f(x)=8*(3.5)^x

Step-by-step explanation:

2=98

3= 98r

4= 98r^2

5= 98r^3

6= 98r^4

98r^4/98, 98 crosses out and its just r^4. r^4= 14706.125/98

r=3.5

So you plug that in and you get f(x)=8*(3.5)^x

I hope this helped. XD
