To get a improper fraction, just multiply whole numberby denominator value plus the numerator value to get the improper fraction, which is 2*10+2/10= 22/10 The fraction for 0.625 would be would be 5/8, a proper fraction.

The theoretical probability that you wil tryout for the school play is 1/10 There is 22 students in your grade that try out for the school play. How many students are in your grade?

Answers

I am pretty sure that it is 220
So all I did is multiply 22x10

Final answer:

To determine the total number of students in your grade, use the equation (1/10)x = 22 and solve for x by multiplying both sides of the equation by 10.

Explanation:

To find out how many students are in your grade, you can set up an equation using the theoretical probability and the number of students who tried out for the school play. The equation can be written as: (1/10)x = 22, where x represents the total number of students in your grade. To solve for x, you can multiply both sides of the equation by 10 to get rid of the fraction. This gives you x = 220, so there are 220 students in your grade.

WILL MARK BRAINLIEST!!!what is the slope of the line that has the equation 4x -2 y = 12 a. 3 b.6

Answers

Answer: $-2$

Step-by-step explanation:

To find the slope of the line , we will write the equation in the form:

$y = mx + x$

where:

$m =$ slope

$c =$ y - intercept.

To write $4x + 2y = 12$ in this form , we will make y the subject of the formula.

Subtract 4x from both sides

$2y = -4x + 12$

Divide through by 2 $y = -2x + 6$

Therefore :

$slope = -2$

Explain how you can use reasoning to compare two fractions with the same denominator

Answers

When two fractions have a common denominator, its much easier to compare. Therefore, you look at the numerator and see which is bigger.

To compare fractions with the same denominator makes it easier to find out which fraction is bigger. Therefore, this is how you can use reasoning to compare two fractions with the same denominator

1/4 (8× - 4) = 5x + 8

Answers

Answer:

x = -3

Step-by-step explanation:

What you do is get x by itself.

1/4(8x - 4) = 5x + 8 Distribute 1/4 to 8x and -4.

2x - 1 = 5x + 8 Subtract 5x on both sides.

-3x -1 = 8 Add -1 to both sides.

-3x = 9 Divide -3 on both sides.

x = -3

Answer: - 3

Step-by-step explanation:

Expand the brackets

It will give: 2x - 1 = 5x + 8

Collect like terms: 2x - 5x = 1 + 8

- 3x = 9

Divide both sides by - 3

x = -3

You toss a coin three times. What is the probability that it will land heads all those three tosses ?

Answers

The probability would be 1 in 8, or 12.5%

- toss three times
- each time = 2 different possibilities
-3 x 2= 6 chances for heads or tails
6÷2 = 3
-3/6 chances = 50% chance

The probability is 50% or 1/2 to get heads once

to get all three times would be 1/8 or 12.5%
