Answer:

Daniel has 390 marbles.

Step-by-step explanation:

W = 195

2/5D = 4/5W

2/5D = 4/5(195)

2/5D = 156

D = 390

If William has 195 marbles, let's find 4/5 of that.

195 * 4/5 = 156

156 is 2/5 of the marbles Daniel has.

Now we must multiply by the reciprocal

156 * 5/2 ( to find all of Daniel's marbles, not just 2/5) = 390 marbles

Daniel has 390 marbles.

Mrs. Matthews is 24 years old and her daughter Nina is 6 years old. How old will Nina be when she is half as old as her mother?
Lena [83]

Answer:

Nina will be 18 years old when she is half as old as her mother.

Step-by-step explanation:

With the information provided, you can write an equation that indicates that Mrs. Matthews current age plus x which would be the number of years until Nina will be half as old as her mother would be equal to two times nina's age plus x, as you would have to multiply Nina's age at that time for 2 to be equal to her mother's age. The equation would be:

24+x=2(6+x)

Now, you can solve for x:

24+x=12+2x

24-12=2x-x

12=x

Finally, you  have to add the value of x plus Nina's current age to determine her age when she is half as old as her mother:

12+6=18

Acording to this, the answer is that Nina will be 18 years old when she is half as old as her mother.

your car broke down and the final bill was $306.50. The part that was replaced cost $119 and the charge mechanics labor was 75 p
erastova [34]

Answer:

\huge\boxed\text{Equation:}\huge\boxed{\text{Equation:   }119+75x=306.50}\\

\huge\boxed{\text{Hours worked on:   } 2.5}

Step-by-step explanation:

We can create an equation for this problem by converting the words to an equation.

The <em>flat fee</em> was $119. We then add $75 for every hour worked. This means that this becomes 119+75x. Since the total cost was $306.50, the equation is 119+75x=306.50.

We can now solve for x, the amount of hours worked, to find it’s value.

119 + 75x = 306.5\\\\75x=187.5\\\\x = 2.5

Hope this helped!
