Hey there! I'm happy to help!

This is a solution because x has the same value as y. They are both 6.

I hope that this helps! Have a wonderful day! :D

Answer:

Yes.

Step-by-step explanation:

(6,..): this is the x-coordinate

(...,6): this is the y-coordinate.

6=6, so yes, this is a solution to y=x.

No

X would have to equal 6 or greater as if x was 5

5+3 is the same as 8

Answer:

I would say no.

Step-by-step explanation:

If x would be 5, then the greater than sign would turn into a equal sign. This is because 5 + 3 = 8. So this (x + 3 > 8) would turn into this (x [or 5] = 8).

Hope this helped! Goodluck!

Step-by-step explanation:

2(x-11) + 5-1

We can use the distributive property:

We can then simplify:

2x - 18

In this case, if 2x - 18 = 0, then 2x = 18 and x = 9.

Answer: B

Step-by-step explanation:

On a coordinate plane, a triangle is shifted up is the area that shows only a vertical translation from the shaded figure onto the unshaded figure (Image attached).

Vertical translation is known to be a term that connote  the up or down movement that takes place in a graph of a function.

It is also called the movement or the shifting of the graph amidst the y-axis. Note that in vertical translation, all the point on the graph often moves k units vertically.

Answer:

Jennifer's speed is 2.4 miles/hour

Kamlee's speed is 2 miles/hour

Step-by-step explanation:

To find their speed,

Speed can be determined from the formula below,

[tex]Speed = \frac{Distance}{Time}[/tex]

Also, to determine the speed in miles per hour (miles/hour), we will convert the time spent by each of them to hour (NOTE: 60 minutes = 1 hour)

For Jennifer,

Distance = 4/5 miles

Time = 20 mins (Convert to hour)

∴Time = (20/60) hour = 1/3 hour

Hence,

[tex]Speed = \frac{Distance}{Time}[/tex]

[tex]Speed = \frac{4/5 miles}{1/3hour}[/tex]

[tex]Speed = \frac{4}{5} \times \frac{3}{1}[/tex]

[tex]Speed = \frac{12}{5}[/tex]

[tex]Speed = 2.4 miles/hour[/tex]

Hence, Jennifer's speed is 2.4 miles/hour

For Kamlee,

Distance = 5/6 miles

Time = 25 minutes (Convert to hour)

Time = (25/60) hour = 5/12 hour

Hence,

[tex]Speed = \frac{Distance}{Time}[/tex]

[tex]Speed = \frac{5/6miles}{5/12 hour}[/tex]

[tex]Speed = \frac{5}{6} \times \frac{12}{5}[/tex]

[tex]Speed = 2 miles/hour[/tex]

Hence, Kamlee's speed is 2 miles/hour

Answer:

1 2/3a+o=5 1/2

Step-by-step explanation:

1 2/3 pounds of apples plus the weight of oranges is equal to 5 1/2 pounds. The weight of the oranges can be found by subtracting the weight of apples from the total weight, which is 3 5/6 pounds.

The equation which represents the number of oranges and apples is 1²/₃a+o=5¹/₂.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Nancy bought 5¹/₂ pounds of apples and oranges. If she bought 1²/₃ pounds of apples.

The equation will be written as,

1²/₃a+o=5¹/₂.

1²/₃ pounds of apples plus the weight of oranges is equal to 5¹/₂ pounds. The weight of the oranges can be found by subtracting the weight of the apples from the total weight, which is 3⁵/₆ pounds.

Therefore, the equation which represents the number of oranges and apples is 1²/₃a+o=5¹/₂.

G(18,-9)

Step-by-step explanation:

The coordinates of the midpoint of GH are M (8,0) and the coordinates of one endpoint are H(-2, 9). We need to find the coordinates of G. Let G is (x,y).It can be done using mid point formula i.e. [tex](\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]

So,

[tex]8=\dfrac{x-2}{2}\ \text{and}\ 0=\dfrac{9+y}{2}\\\\16=x-2\ \text{and}\ y=-9\\\\x=18\ \text{and}\ y=-9[/tex]

Answer:

$19

Step-by-step explanation:

Since there are 15 players and he bought a basketball for each of them, he bought 15 basketballs in total.

The price of a basketball costs $9.

The total price of all 15 basketballs = $9 * 15 = $135.

He spent $420 on uniforms and basketballs, and he spent $135 on basketballs.

Thus, he spent $420 - $135 = $285 on uniforms.

As he bought a uniform for each of the 15 players, he bought 15 uniforms in total.

The price of 15 uniforms is $285.

The price of 1 uniform is $285 ÷ 15 = $19.

Answer:

$19.

Step-by-step explanation:

Let x be the cost of a uniform:

Then we have 15 (x + 9) = 420.

We can divide both side by 15, getting x + 9 = 28.

Then, we can subtract both sides by 9, getting x = 28 - 9 = 19.
