Ten members of the academic team went to a local restaurant after their contest. Each meal combo that came with soda cost $6.75,
Aneli [31]

Answer:

7 ordered with Soda;

3 ordered with water

Step-by-step explanation:

Given

m \to With water

n \to With Soda

So:

m + n =10 --- total

5m + 6.75n = 62.25 -- cost

Required

Find m and n

m + n =10

Make m the subject

m = 10 - n

Substitute m = 10 - n in 5m + 6.75n = 62.25

5(10-n) +6.75n = 62.25

50-5n +6.75n = 62.25

Collect like terms

-5n +6.75n = 62.25 - 50

-5n +6.75n = 12.25

1.75n = 12.25

Solve for n

n = 12.25/1.75

n = 7

m = 10 - n

m = 10 - 7

m =3

ac + ab = d

Subtract ab from both sides.

ac = d - ab

Divide a on both sides.

c = d - ab / a

Hope this helps!

OverLord2011 [107]

<span>The volume of the cylinder will be 2</span>πR^{3}

 

As shown in figure, R is the base radius of the cylinder.

H is the height of the cylinder.

Given: H = diameter of the base of cylinder.

Now, diameter of the base = 2R

So, H = 2R

<span>Volume of cylinder = π×</span>R^{2}×H

<span>                                  = π×</span>R^{2}×(2R)

<span>                                  = 2 π </span>R^{3} cubic units.
