Answer:

14.x=-2

21. x=-2

23. x=5

7.x=12

2.x=49

Step-by-step explanation:

I got your back bro:

14. Subtract 7 on both sides. Then divide -16 by 8. x=-2

21. Add 1 on both sides. Divide 18 by -9. x=-2

23. Subtract 24 on both sides, then divide -25 by -5. your answer is x=5.

7. Add 2/5 on both sides. then multiply 2 2/5 by the reciprocal of -1/5. Your answer is x=12

2. Subtract 5 on both sides. Multiply 14 by the reciprocal of 2/7, or 7/2. Your answer is 49.

Good luck!

Coffee is sold in two different-sized canisters. The smaller canister has a diameter of 9 cm and a height of 12 cm. The larger c

SVEN [57.7K]

Answer:

Step-by-step explanation:

Smaller Canister:

Height, h = 12cm

Diameter = 9cm

Radius, r = 4.5 cm

$Volume = \pi r^2h\\$

$=\pi \times 4.5^2 \times 12\\\\=243 \pi \ cm^3$

$Surface \ area = 2 \pi r(r + h)\\$

$=2 \times \pi \times 4.5 ( 4.5 + 12)\\\\= \pi \times 9(16.5)\\\\=148.5 \ cm^2$

Larger Canister:

Measures double the smaller canister, that is

height, H = 24 cm

Diameter = 18cm

Radius, R = 9cm

$Volume = \pi R^2 H\\$

$= \pi \times 9^2 \times 24\\\\= \pi \times 81 \times 24 \\\\= 1944 \pi$

$Surface \ area = 2 \pi R(R+ H)$

$= \pi \times 2 \times 9 ( 9 + 24) \\\\= \pi \times 18(33)\\\\=594 \pi \ cm^2$

Comparing results :

$Volume_{small} = \pi r^2 h\\\\Volume_{large} = \pi R^2 H = \pi(2r)^2(2h) = \pi(4r^2)(2h)= 8 \pi r^2h = 8 \times volume_{small}$

Therefore, volume of larger canister is 8 times the volume of smaller canister.

$Surface\ area _{larger} = 2 \pi R(R + H) = 2 \pi(2r)((2r+2h))\\\\$

$=2 \ pi \times 2r \times 2 (r+ h)\\\\= 4 \times 2\pi r(r+ h) \\\\= 4 \times surface\ area_{smaller}$

Therefore, surface area of larger canister is 4 times the surface area of smaller canister.

In South Africa, musicians who perform along the streets are called buskers, and must get a permit, which costs $30. They can ma

lys-0071 [83]

The number of night of work each performers will have equal amount is 1 night

<h3 /><h3>How to find the time of work that the performers will have equal amount?</h3>

The buskers gets permit which cost $30. They can make an average of $45 per night (n),

Therefore,

y = 45n - 30

Without a permit they may only make an average of $15 per night.

Therefore,

y = 15n

The number of night the money made are both equal.

45n - 30 = 15n

45n - 15n = 30

30n = 30

n = 30 / 30

n = 1

Therefore, the number of night of work each performers will have equal amount is 1 night
