3

Step-by-step explanation:

9514 1404 393

  10.8 hours

Step-by-step explanation:

Mr. Chandler has a head start of ...

  (4.5 h)(60 mi/h) = 270 mi

Mrs. Chandler is closing the gap at the rate of ...

  (85 mph) -(60 mph) = 25 mph

At that rate, she will close the 270 mile gap in ...

  (270 mi)/(25 mi/h) = 10.8 h

It will take Mrs. Chandler 10.8 hours to catch up.

After 15.3 hours, Mr. Chandler will have driven 918 miles.

After 10.8 hours, Mrs. Chandler will have driven 918 miles.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

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.
