A baby weighs 18 pounds at her four-month appointment. Six months later she weighs 24 pounds. By what percentage did the baby's weight increase?

Answers

Answer:

33.33%

Step-by-step explanation:

We know that:

At her four month weighs: 18 pounds.

Six month later weighs: 24 pounds.

So, the baby increased 6 pounds. But, what percentage represents?

To solve this problem we use the rule of three:

If 18 pounds represents 100%, 24 pounds what percentage would be?

So, if we subtract 100%-133.33%, we have a 33.33% more. This means that the baby increased a 33.33% during those six months.

Three years ago, claire borrowed money from her father to pay for a class trip. She agreed to pay him 6% simple annual interest on the loan. Now she owes him 90$ in interest, plus the principal amount. How much did Clare borrow? The answer is 500, but how did you get that answer correctly? Step by step can u show me?

Answers

Answer:

Below

Step-by-step explanation:

6% simple annual interest on the loan for 3 years so 6x3=18

So the interest of the whole amount is 18%, so now you got to find what of 18% is 90

This looks like (initial amount)x(number)%=(final amount)

x=initial amount

number%=18

final amount=90

All percentages are just number%/100. So we have either 18/100, or .18 depending on how you want to work it.

So now we do 90÷0.18 which gives you the answer 500

What is the solution to the following equation? -6(x-2) + 3x = -3(x + 3) + 21
(This is not multiple choice and I need the answer in number form, with explanation please) :)

Answers

9514 1404 393

Answer:

no solution

Step-by-step explanation:

Simplifying the given equation, you have ...

-6(x -2) +3x = -3(x +3) +21 . . . . . given

-6x +12 +3x = -3x -9 +21 . . . . . . eliminate parentheses

-3x +12 = -3x +13 . . . . . . . . . . . . collect terms

0 = 1 . . . . . . . . . . . . . add (3x-12) to both sides

There is no value of x that will make this true.

The equation has NO SOLUTION.

-6(x+2) + 3x = -3(x+3) + 21

-6x - 12 + 3x = -3x - 9 + 21

-3x - 12 = -3x + 12

-3x + 3x = 12 + 12

0 = 24

Sorry but this equation has no solution.
-3x + 3x = 0, x is cancelled out so we can’t find ‘x’.
