Answer:

(28 + h + p)/4 = k

Step-by-step explanation:

Step 1: Write equation

h + p = 4(k - 7)

Step 2: Solve for k

Distribute 4: h + p = 4k - 28

Add 28 to both sides: 28 + h + p = 4k

Divide both sides by 4: (28 + h + p)/4 = k

Answer:

45

Step-by-step explanation:

13 x 4 = 52

13 represents # of cars

4 represents tires per car

52 represents total tires

52 tires - 7 damaged tires = 45 undamaged tires

Answer:

45

Step-by-step explanation:

13 * 4=52

52-7=45

45 tires not damaged

Answer:

1. Commutative Property of Addition

2. Distributive property

Step-by-step explanation:

Given

[tex]Line 1: 4(8+9x)[/tex]

[tex]Line 2: 4(9x+8)[/tex]

[tex]Line 3: 36x+32[/tex]

Required

Justify each step

From Line 1 to 2:

The property from Line 1 to 2 depicts [tex]a + b = b + a[/tex];

i.e.

[tex]4(8 + 9x) = 4(9x + 8)[/tex]

This is referred to as Commutative Property of Addition

From Line 2 to 3:

The property here depicts [tex]a(b + c) = a * b + b * c[/tex]

i.e.

[tex]4(9x + 8) = 4 * 9x + 4 * 8[/tex]

[tex]4(9x + 8) = 36x + 32[/tex]

This is referred to as Distributive property

Answer:

Line 1 to Line 2: Commutative Property of Addition

Line 2 to Line 3: Associative Property of Addition

Step-by-step explanation:

does that answer anything

(1) [tex]50y^3=5y\cdot 10y^2[/tex], and

[tex]10y^2\cdot(5y-4)=50y^3-40y^2[/tex]

Subtract this from [tex]50y^3+10y^2-35y-7[/tex] to get a remainder of

[tex](50y^3+10y^2-35y-7)-(50y^3-40y^2)=50y^2-35y-7[/tex]

What we've done here is show that

[tex]\dfrac{50y^3+10y^2-35y-7}{5y-4}=10y^2+\dfrac{50y^2-35y-7}{5y-4}[/tex]

We can keep going as long as the degree of the remainder's numerator is at least the same as the degree of its denominator.

Next, [tex]50y^2=5y\cdot 10y[/tex], and

[tex]10y\cdot(5y-4)=50y^2-40y[/tex]

Subtract this from the previous remainder to get a new remainder of

[tex](50y^2-35y-7)-(50y^2-40y)=5y-7[/tex]

which means

[tex]\dfrac{50y^3+10y^2-35y-7}{5y-4}=10y^2+10y+\dfrac{5y-7}{5y-4}[/tex]

Finally, [tex]5y=5y\cdot1[/tex], and

[tex]1\cdot(5y-4)=5y-4[/tex]

Subtract this from the previous remainder to get

[tex](5y-7)-(5y-4)=-3[/tex]

So we end up with

[tex]\dfrac{50y^3+10y^2-35y-7}{5y-4}=\boxed{10y^2+10y+1}-\dfrac3{5y-4}[/tex]

(the quotient is the expression in the box)

(2) Using the same process as before:

[tex]8m^4=2m\cdot4m^3[/tex]

[tex]4m^3\cdot(2m+1)=8m^4+4m^3[/tex]

[tex](8m^4-4m^2+m+4)-(8m^4+4m^3)=-4m^3-4m^2+m+4[/tex]

[tex]\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=4m^3-\dfrac{4m^3+4m^2+m+4}{2m+1}[/tex]

[tex]-4m^3=2m\cdot(-2m^2)[/tex]

[tex]-2m^2\cdot(2m+1)=-4m^3-2m^2[/tex]

[tex](-4m^3-4m^2+m+4)-(-4m^3-2m^2)=-2m^2+m+4[/tex]

[tex]\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=4m^3-2m^2-\dfrac{2m^2-m-4}{2m+1}[/tex]

[tex]-2m^2=2m\cdot(-m)[/tex]

[tex]-m\cdot(2m+1)=-2m^2-m[/tex]

[tex](-2m^2+m+4)-(-2m^2-m)=2m+4[/tex]

[tex]\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=4m^3-2m^2-m+\dfrac{2m+4}{2m+1}[/tex]

[tex]2m=2m\cdot1[/tex]

[tex]1\cdot(2m+1)=2m+1[/tex]

[tex](2m+4)-(2m+1)=3[/tex]

[tex]\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=\boxed{4m^3-2m^2-m+1}+\dfrac3{2m+1}[/tex]

Answer:

6=x

Step-by-step explanation:

Answer:

x=3

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2*x-4-(4*x-10)=0

Answer:

171 degrees (C)

Step-by-step explanation:

Because you have to find the overall angle you add both angles together, hence giving you 171 (C)

Answer:

171°

Step-by-step explanation:

Angle KJU = 67°     Angle UJI = 104°

By adding 67 and 104, you would get 171, which is the angle of KJI.

Answer:

C.{{1, 5.72), (2, 5.50), (3,5.25}}

Answer:

Option (D)

Step-by-step explanation:

At every 6 crew workers number of clean up kits required = 1

Therefore, for 1 crew worker number of kits required = [tex]\frac{1}{6}[/tex]

And number of kits required for w workers = [tex]\frac{w}{6}[/tex] = w ÷ 6

If w = 54

Number of kits required = [tex]\frac{54}{6}=9[/tex]

If w = 60

Number of kits required = [tex]\frac{60}{6}=10[/tex]

If w = 66

Number of kits required = [tex]\frac{66}{6}=11[/tex]

Therefore, table given in Option (D) is the correct table.

Answer:

A quadratic polynomial is a type of polynomial that cannot be factored

Examples are;

x^2 + 3x + 5

x^2 + 5x + 7

Step-by-step explanation:

A quadratic polynomial is a type of polynomial which cannot be factored. Just like prime numbers, it only has two factors, 1 and itself.

Hence, a quadratic polynomial does not have rational roots. Its roots are complex and not real

Example are as follows;

(i) x^2 + 3x + 5

(ii) x^2 + 5x + 7

➯ A polynomial having degree 2 is called a quadratic polynomial.

➯ The form of quadratic polynomial is

Answer: 60 yd

Step-by-step explanation:

Here: subdivided into 3 smaller pens (2w + w + w) extra widths for separation purposes (3 smaller pens)

180 yards of fencing material

180yd = 2L + 4w

180dy = 2*60 + 4w

60dy = 4w

w = 15yd, how wide can the rectangle can  be with L = 60yd

Answer:

[tex]x = 4[/tex]

Step-by-step explanation:

Solve for [tex]x[/tex] :

[tex]2x - 1 = 7[/tex]

-Add both sides by [tex]1[/tex] :

[tex]2x - 1 + 1 = 7 + 1[/tex]

[tex]2x = 8[/tex]

-Take [tex]2x[/tex] and divide it on both side of the equation:

[tex]\frac{2x}{2} = \frac{8}{2}[/tex]

[tex]x = 4[/tex]

So, the value of [tex]x[/tex] is [tex]4[/tex].

Answer: y= -5/7 x + 1/7

Step-by-step explanation:

Answer:

[tex]y=-\frac{5}{7} x+\frac{1}{7}[/tex]

Step-by-step explanation:

Equation of a line: [tex]y = mx+b[/tex]

m is the slope, and b is the y-intercept.

m = [tex]\frac{rise}{run} =\frac{y_{2}-y_{1} }{x_{2}-x_{1} } = \frac{-2-3}{3-(-4)} =-\frac{5}{7}[/tex]

Now, we have [tex]y=-\frac{5}{7} x+b[/tex]

We can insert one set of points in to solve for b.

We will use the first point (-4, 3):

[tex]3=-\frac{5}{7} (-4)+b[/tex]

[tex]\frac{5}{7}* \:4+b=3[/tex]

[tex]\frac{20}{7}+b=3[/tex]

[tex]b=\frac{1}{7}[/tex].

Equation:[tex]y=-\frac{5}{7} x+\frac{1}{7}[/tex]

Answer:

[tex]\boxed {\tt 23}[/tex]

Step-by-step explanation:

In order to find the mean, we must add all the values together, then divide by the number of values.

1. Add the values together

2. Divide by the number of values.

Count how many values are in the set of data. There are 5 values. Divide by 5.

The mean is 23.
