Answer: 20%

Explanation:
We have to remember a percentage is something out of a total or original amount. In this case, the original price is 25,000.

Now we have to find out how much it decreased. 25,000 to 20,000 is a decrease of 5,000.

Now the percentage is the amount out of the total. This is 5,000 (decrease) out of 25,000 (original price)

5,000/25,000
5/25
20/100
.2 or 20%

Step-by-step explanation:

exactly.

maybe this helps even more : always identify what is supposed to be 100% and what would be 1% then (1/100 of 100%). and then you check how often 1% fits into the amount in question.

100% = 25000

1% = 100%/100 = 25000/100 = 250

the price decrease is 25000 - 20000 = 5000.

so, the percentage is

difference /1% = 5000/250 = 20%

-4(x+1)-3=-3(x-4) solve for x please. Giving brainliest
Sophie [7]

Answer:

-19 = x

Step-by-step explanation:

Step 1: Write equation

-4(x + 1) - 3 = -3(x - 4)

Step 2: Solve for <em>x</em>

<u>Distribute:</u> -4x - 4 - 3 = -3x + 12

<u>Combine like terms:</u> -4x - 7 = -3x + 12

<u>Add 4x on both sides:</u> -7 = x + 12

<u>Subtract 12 on both sides:</u> -19 = x

Please help me i beg of u due today my teacher be buggin
mart [117]

Answer:

1) 35+5w=110

2) the starting heart rate is 73 beats per minute

3)B

4) 6mins

Step-by-step explanation:

1) since she deposits 5 dollars each week we can multiply 5 and w to find out how much money hes depositing after all the weeks are done. We need to add that with 35 to get the TOTAL money in the bank account.

2) 73 is the y intercept. The y intercept is the number when "x" is 0. So when hes just starting out/not excersizing his heart beats 73 beats per min.

3) we know that 10% of her tips is given back to her hence x(number of tips) is multiplied by 0.1, and added to 50 to find the total amount of money she receives

4) 6 mins for 1 order

ANSWER QUICKLY..
astra-53 [7]

Answer:

10 weeks

Step-by-step explanation:

Let's set an equation for you and your brother.

You have $90 plus $18 for every week you save (x).

90+18x

And your brother has $120 plus $15 dollars per week that he saves (x)

120+15x

You want to have the sum of the money equal so combine the two concluded statements

90+18x=120+15x

Arrange them so that you have like terms on each side

90+18x-15x=12+15x-15x

90+3x=120

90-90+3x=120-90

3x=30

x=10

"x" is our number of weeks you and your brother save so the answer is 10 weeks

Just to be sure you can use our equation and plug 10 for every time you see x to make sure our answer is right.
