Answer:

2 1/5

Step-by-step explanation:

First you make both fractions into 5 becomes 25/5. 2 4/5 becomes 14/5. Then you would just subtract 25/5 - 14/5 = 11/5 then make it a mixed number 2 1/5.

Answer:

It would be 2.2 as a decimal, or 11/5 (2 1/5)

Step-by-step explanation:

It's quite simple.

Start by turning 2 4/5 into an improper fraction, then turn 5 into a fraction. By doing that you should get 25/5 - 14/5. Subtract to get 11/5.

hope this helped!

The weight of a baby measured in pounds doubles. Does its weight measured in kilograms also double? Explain your answer.?
kvv77 [185]

bearing in mind that 1Kg ≈ 2.2lbs.

so, if a baby is say 2.2lbs, and then it doubles in weight, to 4.4lbs.

well, we know when the baby was 2.2lbs it was exactly 1Kg, but when it went up to 4.4lbs, is it 2Kgs?  well, yes, 2Kgs = 2.2 + 2.2 or 2(2.2).

so, multiplying the lbs value by some factor, will retain the Kg:lbs ratio.

1.(8x+3)(4x-5) 2.(10x-2)(3x+6) please show your work will mark brainliest
ANEK [815]

Answer:

1)

32x^2 - 28x - 15

2)

30x^2 + 54x - 12

Step-by-step explanation:

1.

(8x+3)(4x-5)

Using FOIL

= (8x)(4x) + (8x)(-5) + (3)(4x) + (3)(-5)

= 32x^2 - 40x + 12x - 15

= 32x^2 - 28x - 15

2.

(10x-2)(3x+6)

Using FOIL

= (10x)(3x) + (10x)(6) + (-2)(3x) + (-2)(6)

= 30x^2 + 60x - 6x - 12

= 30x^2 + 54x - 12

Fernanda bought a 500-milliliter container juice. She used some of the juice and has 200 milliliters left. How much orange juice
tiny-mole [99]

She used 300 milliliters of orange juice. We know this because we subtract 200mL of orange juice from 500mL of orange juice.

500mL-200mL=300mL

Therefore she used 300mL of orange juice.
