Howard uses 2/5 of a bag of flour to make a sheet cake. How many bags of flour would he need to make 3 1/2 sheet cakes? MULTIPLE CHOICE
a) 3 9/10 bags b) 3 1/10 bags c) 3 bags d) 1 2/5 bags e) 1 2/7 bags

1 2/5 bags

Step-by-step explanation:

We can use ratios to solve

2/5 bag         x bags

 =

1 cake          3 1/2 cakes

Change to an improper fraction

2/5 bag         x bags

 =

1 cake           7/2 cakes

Using cross products

2/5 * 7/2 = 1 *x

7/5 =x

Changing back to a mixed number

1 2/5 bags

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
