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.

Ainat [17]

Answer:

$\$1,176$

Step-by-step explanation:

The complete question in the attached figure

we know that

To find out how much money the total snake exhibit earned in 6 days, add up the total number of visitors to the snake exhibit each day for 6 days and multiply that by the cost of admission per person

Find the total number of visitors for 6 days

$30+25+44+12+25+32=168\ visitors$

Multiply the total number of visitors by the admission cost per person

$168(7)=\$1,176$

What is the final answer for 6x-6-7x=-13/2

olya-2409 [2.1K]

6x - 6 - 7x = -13/2

Multiply both sides by 2:
12x - 12 - 14x = -13

Simplify:
-2x - 12 = -13

Add 12 to both sides:
-2x = -1

Divide both sides by 2:
-x = -1

Change to a positive value of x:
x = 1
