13 less than fourteen times a certain number is twenty-nine more than 7 times that number. What is the number? (I only need the answer) A. 12
B.6
C.7
D.9

B. 6

Step-by-step explanation:

Let x be the [certain number]

Rephrase the expression

13 less than fourteen times a certain number is twenty-nine more than 7 times that number

14x-13=7x+29

Calculate

Given

14x-13=7x+29

Add 13 on both sides

14x-13+13=7x+29+13

14x=7x+42

Subtract 7x on both sides

14x-7x=7x+42-7x

7x=42

Divide 7 on both sides

7x/7=42/7

x=6

Hope this helps!! :)

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg
