Answer:

C. X = 1/2

Step-by-step explanation:

4x - 3 + 5 = 2x + 7 - 8x

      4x +2 = - 6x + 7

    4x + 6x = 7 - 2

           10x = 5

               x = 1/2

Answer:

It is C or t < 6

Step-by-step explanation:

The line starts at 6 and goes left. The way I remember which way it goes is the greater than or less than sign looks like the tip to the arrow

< ----   and  ---- >

It is an open circle so it will not be a greater than or equal to sign

Answer:

12

Step-by-step explanation:

912 - 612 = 300

300 ÷ 25 = 12

The number of uniforms the school purchased based on the given data and equation formation will be $12.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's suppose the school purchase x number of uniforms.

Total cost = equipment cost + x uniforms cost

912 = 612 + 25x

912 - 612 = 25x

25x = 300

x = 12

Hence "The number of uniforms the school purchased based on the given data and equation formation will be $12".

Answer:

SSS

Step-by-step explanation:

The two triangles both share a side (the middle line), and it is shown that the other lines are congruent to each other. So all 3 sides are congruent, meaning SSS is the postulate that proves this.

Answer:

6

Step-by-step explanation:

treat the ? as an x. you need to get it by itself. but first you should distribute the 8.

8x + 24 = 48 +24

8x+24 = 72

take the 24 and subtract it from 72

8x= 48

now divide both sides by 8

x= 6

Answer:

6

Step-by-step explanation:

8(6 + 3) =48+24

8(9) = 48+24

72 = 48 + 24

72 = 72

Answer:

x=2

Step-by-step explanation:

So you make the equation equal. f(x)=10 so you would put it as 10=4x+2, than you subtract two from both sides making it 8=4x and than divide both sides by 4 making it 2=x.

Answer:

[tex]\boxed {\boxed {\sf x=2}}[/tex]

Step-by-step explanation:

We know that:

[tex]f(x)=4x+2 \\f(x)= 10[/tex]

Both 4x+2 and 10 are equal to f(x). We can use substitution and set 4x+2 and 10 equal to each other.

[tex]4x+2=10[/tex]

Now, solve for x. Perform the inverse operations to isolate x on one side of the equation.

2 is being added to 4x. The inverse of addition is subtraction. Subtract 2 from both sides of the equation.

[tex]4x+2-2=10-2[/tex]

[tex]4x=10-2 \\[/tex]

[tex]4x=8[/tex]

x is being multiplied by 4. The inverse of multiplication is division. Divide both sides of the equation by 4.

[tex]\frac{4x}{4} =\frac{8}{4}[/tex]

[tex]x=\frac{8}{4}[/tex]

[tex]x=2[/tex]

For the function f(x)= 4x+2, when f(x)=20, x=2

Answer:

It is not linear because it does not have a constant rate of change

Step-by-step explanation:

See attachment for Jordana's graph

From the attachment, it'll be observed that the graph has a curved line.

This means that the graph is not a linear and does not represent a linear function.

In functions, a linear representation has a constant slope (in other words, constant rate of change) while non linear representations do not.

So, since we've been able to establish that the graph is non linear, then we can conclude that the graph do not have a constant slope.

Base on the analysis above and from the list of given options, option (d) is correct.

Answer: No. The two frames does not have the same ratio of white shells to orange shells.

Step-by-step explanation:

Ryan glued 9 white shells and 15 orange shells to the border of his frame. This will give us a fraction of:

9/15 = 3/5

The ratio is 3:5

Russell glued 8 white shells and 10 orange shells to the border of his frame. This will give us a fraction of:

= 8/10 = 4/5

The ratio will be 4:5.

Therefore, the two frames does not have the same ratio of white shells to orange shells.

Answer:

The second train speed is 356.4 miles per hour

And, the first train speed is  361 miles per hour

Step-by-step explanation:

The computation of the speed of each train is as follows

Given that

The Sum of the speed of two trains is 717.4 miles per hour

Let us suppose the second train speed be x

So for the first train, the speed is x + 4.6

Now the equation is

x + x + 4.6 = 717.4

2x + 4.6 = 717.4

2x = 717.4 - 4.6

2x = 712.8

x= 356.4

Therefore the second train speed is 356.4 miles per hour

And, the first train speed is = 356.4 + 4.6 = 361 miles per hour

Answer:

We could think of the Earth as a sphere, where the diameter of this sphere will the mean diameter between the measure from the North pole to the Soth pole and the measure from opposite points of the equator.

Remember that the mean between two numbers A and B is:

Mean = (A + B)/2

In this case, the mean diameter will be:

D = (7,899.83mi + 7,926.41mi)/2 = 7,913.115 mi

And we know that the surface of a sphere of diameter D is:

S = 4*pi*(D/2)^2

Where pi = 3.14

Then the surface of the Earth will be something like:

S = 4*3.14*(7,913.115mi/2)^2 = 196,618,601.47 mi^2

b) We know that 75% of the Earth's surface is water, now we will use the diameter 7,926.41 mi to compute the surface.

First, the total surface of the Earth will be:

S = 4*3.14*(7,926.41mi/2)^2 = 197,279,843.03 mi^2

And 75% of this is water, then the total water surface is 0.75 times that area, this is:

water surface = 0.75*197,279,843.03 mi^2 = 147,959,882.27 mi^2

Answer:

Step-by-step explanation:

Given the data:

1, 3, 2, 2, 1, 3, 3, 1

The mean absolute deviation :

Sum of (1, 3, 2, 2, 1, 3, 3, 1) = 16

Mean = 16 / 8 = 2

Mean absolute deviation :

|1 - 2|+ |3 - 2| + |2 - 2| + |2 - 2| + |1 - 2| +|3 - 2| + |3 - 2| + |1 - 2|

= 1 + 1 + 0 + 0 + 1 + 1 + 1 + 1
