Could anyone help me with this problem? I understand that you can cross multiply but is there a shorter way?

There are several steps needed. I'm not sure this is what you call a shorter way, but I hope it helps!! :)

1) 3 lbs covers 1800 ft2 but we need to find how many ft2 1lb will cover. Divide # of lbs of seed available (3 lbs in this case) into the # of ft2 the available seed will cover (1800ft2 in this case):
1800ft2/3lbs=600ft2

So 1 lb covers 600ft2.

2) Now to find how many lbs 8400 needs. Divide the # of ft2 for 1 lb into the # of ft2 total (8400ft2 in this case):
8400/600ft2 (for 1lb) = 14 lbs

3) 14 lbs is now how many bags? The question does not say how many lbs in 1 bag.

IF ASSUMING the bags are 3lbs each, you divide the # of lbs per bag into the # of total lbs (14lbs in this case).

14lbs/3lb bags= 4.7 bags needed

IF 4lb bags:
14lbs/3lb bags= 3.5 bags needed

IF 5lb bags:
14lbs/5lb bags= 2.8 bags needed

IF 6lb bags:
14lbs/6lbs= 2.3 bags needed

Factors are (y - 7)(5y - 43)

Step-by-step explanation:

  • Step 1: Given, 5x² + 12x + 4 = (x + 2)(5x + 2)

Now, to factor 5(y - 9)² + 12(y - 9) + 4. Here, y - 9 can be equated to x if both equations are compared.

  • Step 2: To factorize, substitute y - 9 for x in the factors (x + 2)(5x + 2)

⇒ Factors = (y - 9 + 2)[5(y - 9) + 2]

                 = (y - 7)(5y - 45 + 2)

                 = (y - 7)(5y - 43)

Sue drove her car 253 miles in january, 277 miles in february, and 280 miles in march. if her average mileage for the four month
Ostrovityanka [42]
X= miles driven in April


(253 + 277 + 280 + x)/4= 284
add in parentheses

(810 + x)/4= 284
multiply both sides by 4

810 + x= 1136
subtract 810 from both sides

x= 326 miles


ANSWER: She must drive 326 miles in April to average at least 284 miles January through April.

Hope this helps! :)
