Answer:

\Huge \boxed{2x-3=-21}

Step-by-step explanation:

Let the number be x.

The difference of two values is the result from subtracting them.

2x-3=-21

Add 3 to both sides.

2x=-18

Divide both sides by 2.

x=-9

The number is -9.

A bag contains 8 red marbles, 3 blue marbles, and 1 green marble. Find P(not blue). a. 9 c. One-fourth b. Four-thirds d. three-f
gayaneshka [121]

In order to find the probability of drawing a marble that is NOT BLUE, we must find the ratio of non-blue marbles to the total amount of marbles

Let's count how many marbles total there are first

8 red + 3 blue + 1 green = 12 marbles total

Now, how many marbles are there that <u>ARE NOT BLUE </u>

8 red + 1 green = 9 marbles <u>THAT ARE NOT BLUE </u>

Now<em> let's create a ratio</em> to find a probility

9/12

This can be simplified to 3/4 by taking out the common factor of 3

Your answer is D! "three-fourths"

Refer to Expression 1 and Expression 2.
TiliK225 [7]

Expression 1 is 25

6*7-3^2*9+4^3

First simplify all the exponents to get 6*7 - 9 * 9 + 64 and then multiply the two numbers to get 42 - 81 + 64 and just add = 25

For expression 2, if you put the parantheses around (5+4)*2+6-2*2-1, it'll be 19

(5+4)*2+6-2*2-1

9*2+6-2*2-1

18+6-4-1

24-5

19

Can the formula F=ma be a direct variation equation? If so, which variable would have to be held constant?
ANEK [815]
Yes it can be a direct variation.  it follows the form y = kx
The only variable that cannot be held constant is F, but we can hold the mass constant and vary the acceleration OR we can hold the acceleration constant and vary the mass.  Either one would work, but the easiest would be to vary the mass and hold the acceleration constant since we are all pulled by the same action gravity
