Answer:

The next two numbers are -7500 and 37500

Step-by-step explanation:

To find the pattern, divide any number by the previous.

-300/60 = -5.

Meaning they are being multiplied by -5, so we can just multiply this to the last number.

1500 * -5 = -7500,

-7500 * -5 = 37500.

If you add 21 to my number and then multiply the result by 3, you will get 84 more than two-thirds of my number. Find my number.

Ksivusya [100]

Based on the calculations, the unknown number is equal to $\frac{-45}{7}$

Let the unknown number be x.

<h3>How to find an unknown number:</h3>

Translate the word problem into an algebraic expression, we have;

Adding 21 to the unknown number:

$21 +x$

Multiplying the result by 3:

$3\times (21+x)$

84 more than two-thirds of the unknown number:

$\frac{2x}{3} +84$

Equating the equations, we have:

$3\times (21+x) = \frac{2x}{3} +84\\\\43+3x=\frac{2x}{3} +84$

Cross-multiplying, we have:

$43+3x=\frac{2x}{3} +84\\\\129+9x=2x+84\\\\9x-2x=84-129\\\\7x=-45\\\\x=\frac{-45}{7}$

Can I get help on this

88% of 300
0.88 x 300 = 364

24 out of 120
24 / 120 = 0.2
Move the decimal two places to the right: 20.
20%
-
3 is 12% of (unknown number)
12% × x = 3
or 12 / 100 × x = 3
Multiplying both sides by 100 and dividing both sides by 12,
we have x = 3 × (100/12)
x = 25
