2n + 3n + 4n. = 63

9n = 63

n = 63/9

n = 7

hope it helps

Answer 2

Answer:

n=7

Step-by-step explanation:

add 2n+3n+4n, which gives 9n =63

Divide by 9 on both sides, 9n/9 =63/9

n=7

If you need to confirm that's the right answer, just plug 7 back as n

The Dial and the Lewis families when to Taco Box for dinner. The Dials bought 3
burrito meals and 4 taco meals for $48. The Lewis' bought 6 burrito meals and 2
taco meals for $60. How much does a burrito meal cost? How much does a taco
meal cost?

Answers

Answer:

A burrito costs $8, while a taco costs $6.

Step-by-step explanation:

Given that the Dial and the Lewis families when to Taco Box for dinner, and the Dials bought 3 burrito meals and 4 taco meals for $ 48, while the Lewis' bought 6 burrito meals and 2 taco meals for $ 60, to determine how much does a burrito meal cost and how much does a taco meal cost make the following calculations:

3B + 4T = 48

3B = 48 - 4T

6B + 2T = 60

6B = 60 - 2T

3B = 30 - 1T

30 - 1T = 48 - 4T

30 = 48 - 4T + 1T

30 - 48 = -3T

-18 = -3T

-6 = -T

6 = T

3B + 4x6 = 48

3B + 24 = 48

3B = 24

B = 24/8

B = 8

6x8 + 2x6 = 60

48 + 12 = 60

60 = 60

Thus, a burrito costs $ 8, while a taco costs $ 6.

Radius of sphere js 6 centimeters what is volume

Answers

the equation for volume of sphere is 4/3 x π x r^3

so just put the numbers in

4/3 x π x 6^3

= 288 π cm^3

Answer:

The volume of a sphere is given as

4/3 πr^3

There is only one variable, the radius, which we are given in the problem.

since the radius is 6 cm, we can plug that in to the formula

4/3 π6^3

Put this into the calculator, and we see that the volume is 904.8cm rounded to the nearest tenth.

The school can expect to raise approximately £85.71 for charity if 60 people played the game.

If each player pays 30p to play the game, and 60 people played the game, the total amount raised by the school would be:

Total amount raised = Number of players * Cost per player

Total amount raised = 60 * 30p

Now, let's calculate the cost of the crisps won by the players:

Cost of crisps won = Number of crisps won * Cost per crisp

Since each bag of crisps costs 20p, and players have to score exactly 7 to win a bag of crisps, we need to determine the number of bags of crisps won.

To find the number of bags of crisps won, we divide the total number of players by the number of players required to win a bag of crisps:

Number of bags of crisps won = Number of players / Number of players required to win a bag of crisps

Number of bags of crisps won = 60 / 7

Now, we can calculate the cost of the crisps won:

Cost of crisps won = Number of bags of crisps won * Cost per crisp

Cost of crisps won = (60 / 7) * 20p

Finally, to determine the amount the school expects to raise for charity, we subtract the cost of the crisps won from the total amount raised:

Amount raised for charity = Total amount raised - Cost of crisps won

Amount raised for charity = 60 * 30p - (60 / 7) * 20p

To simplify the calculation, we can convert the pence to pounds by dividing by 100:

Amount raised for charity = (60 * 30) - (60 / 7) * 20 = £(1800 - (1714.2857))

Amount raised for charity ≈ £85.71 (rounded to two decimal places)

Therefore, the school can expect to raise approximately £85.71 for charity if 60 people played the game.

The total cost of a tablet device comprises the cost of material, labour and overheads in the ratio 3:4:1. The cost of material is $315. What is the total cost of the tablet?​

Answers

Answer:

$840

Step-by-step explanation:

Given data

The cost of material is $315

The ratio is

3:4:1

The total number of part is

3+4+1= 8

Let us apply the part to all method

let the total cost be x

hence

3/8=315/x

cross multiply

3x= 8*315

3x= 2520

divide both sides by 3

x= 2520/3

x= $840

Hence the total money is $840
