Answer:

the value is -4

Step-by-step explanation:

6(2b-4) b=5 so plug that in

6(2(5)-4) distribute 2 to 5 (multipy 2 and 5)

6(10-4) now, distribute 6 to 10 and -4 (multiply 6 by 10 and -4)

60-240 then, divide -240 by 60

-4 is your answer

7. Marie can make 12 small mango pies for every 10 mangoes. How many pie

Marysya12 [62]

Answer:

D. Marie can make 60 pies.

Step-by-step explanation:

In this problem, we know that amount of small mango pies is directly proportional to the amount of mangoes. The amount needed for preparing an amount of pies is calculated by simple rule of three:

A. Marie can make 30 pies.

$x = \frac{10\,mangoes}{12\,pies}\times 30\,pies$

$x = 25\,mangoes$

25 mangoes are required for producing 30 pies.

B. Marie can make 40 pies.

$x = \frac{10\,mangoes}{12\,pies}\times 40\,pies$

$x = 33.333\,mangoes$

34 mangoes are required for producing 40 pies.

C. Marie can make 50 pies.

$x = \frac{10\,mangoes}{12\,pies}\times 50\,pies$

$x = 41.667\,mangoes$

42 mangoes are required for producing 50 pies.

D. Marie can make 60 pies.

$x= \frac{10\,mangoes}{12\,pies}\times 60\,pies$

$x = 50\,mangoes$

50 mangoes are required for producing 60 pies.

The complete statement is: Marie can make 12 small mango pies for every 10 mangoes.How many pies can she make with 50 mangoes.

Hence, correct answer is D.
