A

Step-by-step explanation:

Unit rates means is a rate that compares something to "1" :)

Answer:

Step-by-step explanation:

Step one:

given data

time takent= 3.5hours

distance = 60.9miles

the average speed is given as

Average speed= distance/time

Average speed= 60.9/3.5

Average speed= 17.4mph

Step two:

we are told that the speed was actually maintained, so we used the previous value obatained for the following computation

For a time taken as 1 hour, the distance will be

distance= average speed * time

distance= 17.4*1

distance= 17.4 miles

Answer:

Step-by-step explanation: A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour?

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

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".

Step-by-step explanation:

Answer: Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

Step-by-step explanation: To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

Answer:

f(-2) = -40

Step-by-step explanation:

f(x) = 2(x - 3) • 4

Plug in -2 for x.

f(-2) = 2(-2 - 3) • 4

Follow PEMDAS

f(-2) = 2(-5) • 4

f(-2) = -10 • 4

f(-2) = -40

Answer:

[tex]f(x) = 2(x - 3) \times 4 \\ f(x) = 8(x - 3) \\ f( - 2) = 8( - 2 - 3) \\ f( - 2) = 8 \times ( - 5) \\ \boxed{f( - 2) = - 40}[/tex]

Answer:

140

Step-by-step explanation:

We first find out how much degrees altogether in the pentagon so we do

S = (n-2) x 180

s is the sum in the shape

n is the number of sides

S = (5-2) x 180

S = 3 x 180

S =540

Now that we have the sum we can add all the sides, first lets make the side ABC = x and side BCD = 2x:

115 + 125 + 90 + x + 2x = 540

330 + 3x = 540

3x = 540 - 330

3x = 210

x = 70

Now that we know x = 70 we can find side BCD, it says its is 2 x angle ABC

so we do 2x70 = 140

so Angle BCD = 140

I hope i did this correctly.
