Answer:

Second number line represents the [X-5]=1.

Step-by-step explanation:

Given : [X-5]=1 .

To find : Which number line represents the solutions to [X-5]=1.

Solution : We have given that [X-5]=1.

We can se the value x-5 is inside the modulus it may be positive or negative.

So, we will do it by both cases.

1) (x - 5) = 1

On adding by 5 both sides.

x = 1+5 = 6

x = 6.

2) if -(x-5) = 1

remove parenthesis

-x +5 = 1

On subtracting by 5 both side

-x = -4

On dividing by -1 both side

x = 4.

So , x = 4, 6.

Therefore , the second number line represents the [X-5]=1.

Answer:

Denay scored 7 points during his basketball game.

Step-by-step explanation:

Given that,

Bari scored 28 points.

During the same game, Denay scored 1/4 the number of points Bari scored.

Denay scored = (1/4) × Bari scored

= (1/4)×28

= 7

Hence, Denay scored 7 points during his basketball game.

Answer: 4 5/12 miles

Step-by-step explanation: To add or subtract two fraction, you need to find a common denominator. The easiest way to do that is to just multiply the denominators of the two fractions together. 3 x 4 = 12 so I'll use 12 as my common denominator. Now that we have that, we have to convert the numerators. We must multiply the numerators by the same number we multiplied or denominators by to get the common denominator. 3 x 4 = 12, 4 x 3 = 12, 2 x 4 = 8, 3 x 4 = 12. Now the fractions we have are 9/12 and 8/12. Since they have the same denominator now we can add them. 9/12 plus 8/12 equals 17/12 or 1 and 5/12 written as a mixed number. We also add the whole numbers. 1 plus two equals 3. 3 plus 1 and 5/12 equals 4 and 5/12.

Answer:

12 ounces flour

Step-by-step explanation:

4 ounces 12 cup cakes

8 ounces 24 cup cakes

12 ounces 36 cup cakes

Answer:

12

Step-by-step explanation:

Because y=24 and x=2 you do the following:

144/24=6

Then, 6x2=12 because it is proportional

Or you could do 24/2=12 and 144/12=12

Answer:

mean- 66

median- 7

mode- 8

range- 6

Step-by-step explanation:

to find the mode you line up all the numbers, add them all together and then divide that number by 2.

to find the median you line up all the numbers then one by one taking turns from left to right you cross of the numbers to find the number in the middle. (think of median as middle)

to find mode you just find the number that is used the most. (mode=most)

to find the range you find the highest number and the lowest number. and subtract the lowest from the highest to find the difference between the 2. in this case its 9-3 so the difference is 6.

Answer:

[tex]\huge\boxed{\angle\text{CUE}}[/tex]

Step-by-step explanation:

We can model what both readings of this angle would be. Angle names are usually formed by taking the two lines that form to intersect this angle at a vertice, and these 3 make up the name.

Angle ∠CUT would be formed by the lines CU and UT. We can see that this is not the case, as the angle is formed by lines CU and CE.

Since they intersect at point U, that means the angle name would be CUE.

Hope this helped!

Answer:

y=2/3-1.

Step-by-step explanation:

Slope intercept is the easiest out of the forms because you just plug in what is given. Here you are given 2/3 for the slope and the y-int Is -1.

The formula for slope intercept is y=mx+b

m= slope

b= y-int

And you just plug it in.

so the answer would be: y=2/3-1. Hope this helps!

12 x 8 is 96. Since a bucket of paint can cover 75,you would subtract 96 from the 75.That gives you 21.So if she only has one gallon,only 21 will remain unpainted.

Answer:

[tex]-\frac{8}{x-a}[/tex]

Step-by-step explanation:

[tex]\frac{8}{a-x}[/tex]

we can take common factor of -1 in the denominator

[tex]\frac{8}{-(-a+x)}=\frac{8}{-(x-a)}[/tex]

and now multiply and divide by -1

[tex]\frac{8}{-(x-a)}\cdot \frac{-1}{-1}=\frac{-8}{x-a}=-\frac{8}{x-a}[/tex]
