The ratio of mikes savings to nicks savings was 4: 3 after mike saved another $120 and nick saved another $60 the ratio became 8: 5 what was their combined savings before each of them saved additional money

Mike's savings before he saved additional money = $120

Nick's savings before he saved additional money = $90

Step-by-step explanation:

The ratio of mikes savings to nicks savings was 4:3.

Let their savings be 4k and 3k.

After mike saved another $120 and nick saved another $60, their savings become 4K+120 and 3k+60.

It is given that the new ratio is 8:5.

Therefore,

4k+120 : 3k+60 = 8:5

5(4k+120) = 8(3k+60)

20k+600 = 24k+480

20k-24k = 480-600

-4k = -120

k = 30

So, Mike's savings before he saved additional money = 4k = 4(30) = $120

Nick's savings before he saved additional money = 3k = 3(30) = $90

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
