What is 1 1/3 as a improper fraction

Mumz [18]

Okay so for this all you have to do is add 1 to 1/3.

However, to do this you first need to convert 1 into a fraction.

1 = 3/3
3/3 + 1/3 = 4/3

Hope this helps :)

Prove that: 5^31–5^29 is divisible by 100.

ANEK [815]

Answer:

See explanation

Step-by-step explanation:

Consider the expression

$5^{31}-5^{29}$

First, factor it:

$5^{31}-5^{29}=5^{29}\cdot(5^2-1)=5^{29}\cdot (25-1)=24\cdot 5^{29}$

Note that

$100=25\cdot 4$

Then

$5^{31}-5^{29}=24\cdot 5^{29}=6\cdot 4\cdot 25\cdot 5^{27}=6\cdot 100\cdot 5^{27}$

This shows that number 100 is a factor of the expression $5^{31}-5^{29}$ and, therefore, this expression is divisible by 100.

I need to know how to solve it and get the answer right to check my work

Solve it by finding out how many times 22 can be put into 22, which is once, so the answer is 1.

Westley and Buttercup are each saving money. Westley starts with $85 in in his savings and add $5 per week (y=85+5x)

love history [14]

Answer:

After 5 weeks.

Step-by-step explanation:

Westley starts with $85 and saves $5 per week. So:

$y=85+5x$

Buttercup starts with $10 and saves $20 per week. So:

$y=10+20x$

When they have the same amount of money, the two equations will be equal to each other. Therefore:

$85+5x=10+20x$

Solve for x. Subtract 10 from both sides:

$75+5x=20x$

Subtract 5x from both sides:

$75=15x$

Divide both sides by 15:

$x=5$

Westley and Buttercup will have the same amount of money after 5 weeks.
