A baker is making walnut bread. The recipe uses 2/3 cups of walnuts for each bread recipe. The baker has 7 1/2 cups of walnuts.
Lady_Fox [76]

Answer:

11 breads

Step-by-step explanation:

Note that:

1 bread recipe = 1 bread

From the above question, we know that:

2/3 cups of walnut = 1 bread

7 1/2 cups of walnut = x breads

Cross Multiply

2/3 cups × x breads = 7 1/2 cups × 1 bread

x breads = 7 1/2 cups × 1 bread/2/3 cups

x breads = 7 1/2 ÷ 2/3

x breads = 15/2 ÷ 2/3

x breads = 15/2 × 3/2

x breads = 45/4

x breads = 11 1/4 breads

Maximum full recipe = 11 breads.

Therefore, the MAXIMUM numbers of full recipe of walnut bread the baker can make is 11 breads.

Find two consecutive odd integers such that 77 more than the lesser is six times the greater.
Salsk061 [2.6K]

Answer:

The answer to your question is : number 1 = 13    number 2 = 15

Step-by-step explanation:

# 1 = 2n +1

# 2 = 2n +3

Conditions:

2n + 1 + 77  = 6(2n + 3)            

Simplify              2n + 78 = 12 n + 18

Solve it for n       12n - 2n = 78 -18

                            10n = 60

                              n = 60/10

                              n = 6

But

     # 1 = 2n + 1 = 2(6) + 1 = 12 + 1 = 13

     # 2 = 2n + 3 = 2(6) + 3 = 12 + 3 = 15
