15. Jim had 103 red and blue marbles. After giving of his blue marbles and 15 of his red marbles
sesenic [268]

This question above is incomplete

Complete Question

Jim had 103 red and blue marbles. After giving 2/5 of his blue marbles and 15 of his red marbles to Samantha, Jim had 3/7 as many red marbles as blue marbles. How many blue marbles did he have originally?

Answer:

70 Blue marbles

Step-by-step explanation:

Let red marbles = R

Blue marbles = B

Step 1

Jim had 103 red and blue marbles.

R + B = 103.......Equation 1

R = 103 - B

Step 2

After giving 2/5 of his blue marbles and 15 of his red marbles to Samantha, Jim had 3/7 as many red marbles as blue marbles

2/5 of B to Samantha

Jim has = B - 2/5B = 3/5B left

He also gave 15 red marbles to Samantha

= R - 15

The ratio of what Jim has left

= Red: Blue

= 3:7

= 3/7

Hence,

R - 15/(3/5)B = 3/7

Cross Multiply

7(R - 15) = 3(3/5B)

7R - 105 = 3(3B/5)

7R - 105 = 9B/5

Cross Multiply

5(7R - 105) = 9B

35R - 525 = 9B............ Equation 2

From Equation 1, we substitute 103 - B for R in Equation 2

35(103 - B) - 525 = 9B

3605 - 35B - 525 = 9B

Collect like terms

3605 - 525 = 9B + 35B

3080 = 44B

B = 3080/44

B = 70

Therefore, Jim originally had 70 Blue marbles.

6m-6=9m+15 (Show work)​
9966 [12]

Answer:

m=-7

Step-by-step explanation:

6m-6=9m+15

Add 6 to both sides:

6m-6+6=9m+15+6

6m=9m+21

Subtract 9m from both sides:

6m-9m=9m+21-9m

-3m=21

Divide both sides by -3:

\frac{-3m}{-3}=\frac{21}{-3}

m=-7

What is the volume to the nearest tenth of cubic inch.
oee [108]

Answer:

180.6 cubic inches. (Nearest tenth is the same as 1 decimal place)

Step-by-step explanation:

The volume of a cylinder formula is:

V

=

π

r

2

h

The diameter is

10

inches, well half of the diameter is

5

inches which is the radius. Radius is half of the diameter.

If you want the diameter back, just double it.

5

+

5

=

10

.

So we can now plug the numbers into the formula.

V

=

π

(

5

2

)

(

2.3

)

V

=

π

(

25

)

(

2.3

)

(5 Squared =25)

V

=

57.5

π

But if you didn't want it in terms of

π

, so you multiply:

57.5

×

3.14

=180.55

but rounding that to the nearest tenth is the same as rounding to

1 decimal place so you get

180.6 cubic inches.
