Mr. Anders was three times as old as Kate 5 years ago. Their total age now is 42 years. How old is Kate now?
katrin [286]
We can write this as two equations. Call Mr. Anders' age A and Kate's age K:
A-5=3(K-5)
A+K=42

Then solve for A in the second equation:
A=42-K

Substitute this into the first equation:
(42-K)-5=3(K-5)
-K+37=3K-15
52=4K
K=13

Karen gave an equal amount of m and m's to herself and four friends. Each person receives m and m's equivalent to the largest on
Mariana [72]

Answer:

Karen had 45 m and m's candy.

Step-by-step explanation:

Let the number of m and m's candy be 'x'.

Now given:

Karen gave an equal amount of m and m's to herself and four friends.

So we can say that;

Number of people m and m's candy distributed equally = 5

Also Given:

Each person receives m and m's equivalent to the largest one digit number.

Now we know that;

Largest one digit number is 9.

So we can say that;

Each person receives m and m's = 9

We need to find number of m and m's Karen have.

Solution:

So we can say that;

Total number of m and m's Karen have is equal to Number of people m and m's candy distributed equally multiplied by number of m and m's can each person receives.

framing in equation form we get;

Total number of m and m's Karen had = 9\times5 = 45

Hence Karen had 45 m and m's candy.
