A.$2.00
B. $3.00

Answers

B. $3.00

Because if you round 2.8 to 3 and round 9.25 and get 9 and divide 9 by 3 you get 3 so it’s closest to B.

Answer:

It should be B.

Step-by-step explanation:

You have to divide 9.25/2.8 and you'll get $3.30. I didn't see that answer, so I rounded and got $3.00.

Please solve 7y - 8 = 6y + 1 AND FAST PLEASE

Answers

In order to solve this problem, we must first p it all variables on one side and all numbers on the other.

7y-8=6y+1

We subtract 6y from both sides to cancel it out on the right and have it on the left.

Y-8=1

Now, we put the numbers on the opposing side.

Y=9

We receive the answer Y=9

To check it, we can plug or input 9 into both equations.

7(9)-8=6(9)+1
63-8=54+1
55=55

Now that we know they are equal, we can conclude that the answer is 9.

Answer:

y=9

Step-by-step explanation:

7y-6y= y

y-8=1

y=9

Kristen paid $39 for 60 cans of corn. How much did she pay per can?

Answers

Answer:

.60 per can

Step-by-step explanation:

39 dollars divided by 60 cans

The ratio of the amount of money that Kristen paid to the number of cans gives the amount per can thus it will be $0.6 per can.

What are the ratio and proportion?

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

Kristen paid $39 for 60 cans of corn.

Ratio of the amount to the number of cans,

39/60 = $0.6 per can

Hence "The ratio of the amount of money that Kristen paid to the number of cans gives the amount per can thus it will be $0.6 per can".

On a cold winter night, it snowed all night long. The next morning, you shoveled 1/5 of the driveway in 2/5 of an hour. How many hours will it take to shovel the driveway?

Answers

Answer:

10/5 of an hour. (☞ﾟヮﾟ)☞ also can be written as 2 hours

Step-by-step explanation:

Shoveling 1/5 of the driveway = 2/5 hours

Shoveling the entire driveway (5/5) would take 2/5 (the time it takes to shovel 1/5) times/multiplied by 5 (5/5 is the entire driveway)

2x5 is 10, so it would take 10/5 hours, which can be reduced to 2/1 or 2 hours to shovel the entire driveway.

If b = 3, then b -2 is equivalent to _____.

a. -6
b. 1/9

d. -9

Answers

Answer: 1/9

Wherever you see 'b', replace it with 3, since b = 3

So,

b^(-2) = 1/(b^2)

b^(-2) = 1/(3^2)

b^(-2) = 1/9

The answer would be B

In this question, the algebra equation is a[3(5b - c)]. Since a = 1.6, b = 2, and c = 5, we would replace the equation into 1.6[3((5)(2) - 5)).

With this equation, the answer will be 24

Answer: 24

Step by Step Explanation:
Since we know what our variables are, we will plug in 1.6 for a, 2 for b, and 5 for c.

1.6[3(5(2) - 5)]

Now we solve and work from the inside out!

1.6[3(10 - 5)]

1.6[3(5)]

1.6 • 15

= 24

So our answer is 24!
