Can anybody me with these 3 problems they are all division and you

1. 12

2. 3/28

3. 2

Step-by-step explanation:

1. Multiply both sides by the reciprocal of 1/3 which is 3. So that would be 4 × 3, which equals 12.

2. Multiply both sides by the reciprocal of 7/2, which is 2/7. Then multiply the numerators, (2 × 3) and multiply the denominators, (7 × 8). So the numerator would be 6 and the denominator would be 56. But the fraction isn't simplified; a common number that they can both be divided by is 2. 6 divided by 2 is 3 and 56 divided by 2 is 28, making the final answer be 3/28.

3. 3 1/2 needs to be turned into a complete fraction, so you would mulitply the whole number (3) by the denominator (2) and add the numerator to that answer. That would be 7, and then you multiply both sides by the reciprocal of 7/4 which is 4/7. That makes the fraction 28/14, and you can still divide them by a common number, 14. That makes the final answer 2.

d

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
