You add all of the number and divide the number you added

(7+0+11+10)/3 = 8
I supposed to divided by 4 here since there are 4 numbers but I considered 0 is just 0 so just divided by 3. I hope this answer will help.

D. 2/3

Answers

Answer: 1. B. 1:3

2. A. $(2)/(3)$

Step-by-step explanation:

The ratio of m to n is written as $(m)/(n)$

1. Given : Rachel has 6 pairs of black shoes and 2 pairs of red shoes.

Then, the ratio of pairs of red shoes to pairs of black shoes will be :_

$\frac{\text{No. of pairs of red shoes}}{\text{No. of pairs of black shoes}}\n\n=\dffrac{2}{6}=(1)/(3)$

Which is written as 1:3.

Hence, the ratio of pairs of red shoes to pairs of black shoes = 1:3

Thus , correct option : B. 1:3

2. Given : In a probability experiment, Eric flipped a coin 42 times. The coin landed on heads 28 times.

Then, the ratio of heads to tails in this experiment will be :-

$(28)/(42)=(2)/(3)$

Hence, the correct option is : A. $(2)/(3)$

the first one is A, because you divide both numbers by two, and make sure they are in the right order.

the answer to the second one is 2/3, because 28 divided by 42 is .66666

How many solutions does the equation have? f + 7 = f - 3

Answers

Answer:

there is no solution

Step-by-step explanation:

Answer:

no solutions

Step-by-step explanation:

Given

f + 7 = f - 3

Given any value for f then f + 7 ≠ f - 3

Hence the equation has no solution

Through solving we obtain

f + 7 = f - 3 ( subtract f from both sides )

0 + 7 = - 3

7 = - 3 ← not possible, thus no solution
