Which is different? a) solve 3x+6y=24 for x. b) solve 24−3x=6y for x. c) solve 6y=24−3x for y in terms of x. d) solve 24−6y=3x for x in terms of y. find “both” answers. y= x=

A) Solve 3x+6y=24 for x.

Subtracting 6y from both sides, we get

3x+6y-6y=24-6y

3x = -6y+24

Dividing both sides by 3, we get

x= -2y + 8

b) Solve 24−3x=6y for x.

Subtracting 24 from both sides, we get

24-24−3x=6y-24

-3x = 6y -24.

Dividing both sides by -3, we get

x= -2y + 8.

c) Solve 6y=24−3x for y in terms of x.

Dividing both side by 6.

y=

d) Solve 24−6y=3x for x in terms of y.

Dividing both sides by 3, we get

8 - 2y = x.

x = -2y +8

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
