Bob's lemonade stand received 15 boxes of 75 lemons each. some of the lemons, n, were used in each of 12 pitchers of lemonade. now, there are only 945 lemons left. which equation represents this situation

1125 - 12n  = 945

Step-by-step explanation:

Total lemons = 75 x 15

                      = 1,125 lemons

If "n" lemons were used for each of the pitchers of lemonade, then the total numbers of lemons used is given as :

= 12 x n

= 12n

The equation for the present situation is given by :

1,125 - 12n  = 945 (1)

The value of n can be calculated from equation (1)

12n = 1125- 945

12n =180

n = 180/12

n = 15

This means that 15 lemons were used in each pitcher of lemonade.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
