Answer:

x≤3

Step-by-step explanation:

Step one- This equation has 23 greater than or equal to sign. Which means It can be at most 23

Step two- Find out what times 3x+14=23 In this case the answer is 3.3 Is the biggest number that can be multiplied by 3, +14 to get to 23.

Step three- Rewrite the Answer. Since we know that 3 is the highest numebr possible, we rewrite it to this equation

<h3>x≤3</h3><h3>HOPE THIS HELPS :)</h3>

A bowl contains 4 red marbles and 3 yellow marbles. Tim randomly draws 3 red marbles from the bowl. He replaces each marble afte

mr Goodwill [35]

So,

The probability of drawing a yellow marble is $\frac{3}{7}$ .
Since he replaces the marble after it is drawn out, the probability of drawing another yellow is the same: $\frac{3}{7}$ .

The probability of drawing a red marble is $\frac{4}{7}$ .

In order to get the probability of drawing 2 yellow marbles and 1 red marble, given that each marble is replaced after it is drawn out, we must multiply the fractions together.

$( \frac{3}{7} )( \frac{3}{7} )( \frac{4}{7} ) = \frac{36}{343}$

Because the order of the marbles doesn't matter, we will multiply the probability by 3.
$3( \frac{36}{343} ) = \frac{108}{343}$

andrezito [222]

Answer:

$3x+2y=315\\\\2x+4y=450$

is the system of equations representing the situation.

Step-by-step explanation:

Given:

Alexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2 haircuts and 4 hair dyes takes 450 minutes.

Now, to find the system of equations representing the situation.

Let the number of haircuts be $x.$

Let the number of hair dyes be $y.$

So, Alexandra can give 3 haircuts and 2 hair dyes in:

$3x+2y=315.$

Now, giving 2 haircuts and 4 hair dyes in:

$2x+4y=450.$

Therefore,

$3x+2y=315\\\\2x+4y=450$

is the system of equations representing the situation.

I need to know how to solve in order to find the equation parallel to the one given.

vampirchik [111]

The answer is A.
If you are asked to find an equation parallel to the other, make sure the equations have the SAME SLOPE, DIFFERENT Y-INTERCEPT

Pls I need help and a explanation

tresset_1 [31]

Answer:

20) 7/16 = 0.4375

21) 1/6 = 1.6 repeating

22) 2 4/5 = 2.8

23) 98 2/3 = 98.6 repeating

24) 0.8 = 4/5

25) 26 1/5

26) 72.1 repeating = 72 1/9

27) 0.505 = 101/200

Explanation:

To convert fraction into decimal, divide the numerator by the denominator and that's your answer. For example:

7 ÷ 16 = 0.4375.

To convert a decimal into a fraction, place the number after the decimal point over the number place it's in. For example: If you look at 0.8 , 8 is in the tenths place, so you place it over 10 like this 8/10, and then you simplify. Half of 8 is 4 , and half of 10 is 5, so you'd have 4/5.

For #27, since 505 in 0.505 , is in the thousandths place, you'd put it over 1,000 like this 505/1000 and then you simplify. Look at image above to learn how to simplify 505/1000.⤴⤴⤴
