Which expressions are equivalent to
4(-5z + 2) + (-6) ?

Answer:

x: 148 degrees

y: 32 degrees

Step-by-step explanation:

Hello!

To find the unknown values of these angles, we must understand the concept of intersecting lines. When calculating the angles of the intersecting lines, SQP and RQT are identical values since they are on the opposite ends of each other when given these sorts of problems. This helps us find y being 32 degrees.

On the other hand, to find x, we just need to focus on the line PQR. it's a line, which means that it is 180 degrees. Since SQP is 32 degrees, SQR, or the angle that is x, should be 180-32, which is 148

Answer:

Y=32, X=148

Step-by-step explanation:

By the opposite angle theorem, 32 must equal Y, so Y = 32.

To solve X:

A straight line has an angle of 180 degrees. Therefore, since 32 + X form a straight line, the angle should equal 180.

Solve.

32+X=180

X=180-32

X=148

Answer:

1:5

Step-by-step explanation:

This is because 4x5=20 and 6x5=30 so the scale factor is 1:5

Answer:

1/3

Step-by-step explanation:

Since there are two points between 1 and 2, we can determine that the distance between each point is 1/3. This is because counting the number 2 (since something like 3/3 is equivalent to 1) there are 3 ticks. This means each tick represents 1/3. Therefore the distance between A and B is 1/3.

Answer:

The distance between a and b is 1/3.

Answer:

12.6

Step-by-step explanation:

63.2/5=12.64

Since the question is asking for 1 demical place, that is the tenth demical place.

12.6

Hope this helps!

Answer:

63.2 divided by 5 is 12.64, but to 1 d.p it is 12.6

analyze equation

2x+3x+25=180(straight)

gather common terms

5x+25=180

move the 25

5x=180-25

subtraction

5x=155

divide

x=31

Answer:

125.5

Step-by-step explanation:

Substitute the values for the variables:

(2)^2 + 1.5(3)^4

Do the exponents first:

4 + 1.5(81)

Multiply:

4 + 121.5

Add:

125.5

Answer:

Answer:

[tex]y=\frac{16}{25} x[/tex]

Step-by-step explanation:

If y = 2/5  and  x = 5/8

[tex]y \div x=\frac{2}{5} \div\frac{5}{8}= \frac{2}{5} \times \frac{8}{5} =\frac{16}{25}[/tex]

So [tex]\frac{y}{x} =\frac{16}{25}\\[/tex]  ⇒  [tex]y =\frac{16}{25}x[/tex]

Answer:

Part B: $4.25 tax / Part A: The first Equation,  85 x 1.09 + x = 96.90

Step-by-step explanation:

Part A: She bought 85 songs. The amount of songs times the amount of tax is the total amount of money she spent. X represents the number of dollars. So that's how I got my equation.

Part B explanation: 85 x 1.09 + x = 96.90

                                     x = 4.25

Answer:

its an limit number

Step-by-step explanation:

you can do it because its a limit number so this in't real

Answer:

93 if rounding from 89.5 to 90 counts, if not then 95

Step-by-step explanation:

The first thing you do is add 92+94+79=265

then divide by 3 265/3=88 1/3

so his score has tp be higher than an 88 so lets try 90

92+94+79+90=355: 355/4=88.75

so higher lets try 94

94+94+92+79=359

359/4=89.75

We are given the  slope of the line and a point that it passes through.

We can use the Point-Slope Formula:

[tex]\huge\boxed{\boxed{y-y1=m(x-x1)}}[/tex]

Where

y1 stands for y-coordinate of the point

m stands for the slope of the line

x1 stands for the x-coordinate of the point

Plug in the values and solve:

y-(-4)=-3(x-(-1)

y+4=-3(x+1)

y+4=-3x-3

y=-3x-3-4

y=-3x-7

Answer: Ordered pair (-4,1): y-intercept 5

Step-by-step explanation: The y-intercept is (0,5), the 5 representing the y intercept within the pair. Then the point at where your mouse covers, it shows (-4,1), meaning it’s part of the line that is graphed.

Answer:

9 months

Step-by-step explanation:

1. write out equation

100 + 22x = 298

2. Subtract 100 from both sides

22x = 198

3. Divide 22 from each side

198/22 = 9

hence, Katrina will pay off the sofa in 9 months.

have a great day! :)

Answer:

x=9

Step-by-step explanation:

100-22x=298

x=9

because, 100-298=198

198/22=9 so, X=9

Answer:

Midpoint = (3.5, 4.5)

Perpendicular bisector = y =  [tex]\frac{7}{9}[/tex] x + [tex]\frac{16}{9}[/tex]

Step-by-step explanation:

[] We can solve this using the midpoint formula:

-> See attached

[] Plug-in our coordinates and solve:

[tex](\frac{7+0}{2} ,\frac{0+9}{2} )=(\frac{7}{2} ,\frac{9}{2} )=(3.5,4.5 )[/tex]

[] Now we will find the slope to solve for the perpendicular bisector.

-> We will use slope-intercept form, see attached

[tex]\frac{9-0}{0-7}=\frac{9}{-7}[/tex]

-> The slopes of two perpendicular lines are negative reciprocals of each other, so [tex]\frac{7}{9}[/tex] will be the slope of or perpendicular bisector

-> Now we can solve for the equation by using y – y1 = m ( x – x1), were y1 and x1 are the coordinates of our midpoint

y - 4.5 = [tex]\frac{7}{9}[/tex] (x-3.5)

y - 4.5 = [tex]\frac{7}{9}[/tex] x-[tex]\frac{49}{18}[/tex]

y = [tex]\frac{7}{9}[/tex] x-[tex]\frac{49}{18}[/tex] + 4.5

y =  [tex]\frac{7}{9}[/tex] x + [tex]\frac{16}{9}[/tex]

Answer:

angle b is 121

angle c is 59

Step-by-step explanation:

10x - 19 = 7x + 23

solve for x

10x = 7x + 42

3x = 42

x = 14

To solve for angle B

10x - 19

10(14) - 19

140 - 19

Angle b is equal to 121 degrees

To solve for angle C

we do 121 + 121 + 2x = 360

242 + 2x = 360

2x = 118

x = 59

angle c is equal to 59

Answer:

Figure 1 Line segment. It is written CD (Technically, CD refers to the points C and D and all the points between them, and CD without the refers to the distance from C to D.)

Hey there!

It’s basically the points that are lie along C & D with it not necessarily being the distance points of C & D.

Example: EF are perpendicular to CD or AB are perpendicular to CD. (Either of these should work because perpendicular simply is the line that most likely intersects at a 90° angle

Answer: (x - 4)² - 25

Step-by-step explanation:

[tex]{ \boxed{ \tt{ \: {x}^{2} - 4x - 21 \: }}}[/tex]

» Let us use completing perfect squares to find the final expression.

☑ When completing squares, we first find the "square of the half of the sum"

[tex]{ \boxed{ \tt{square \: of \: sums \: half = {( \frac{ - 4}{2} )}^{2} = {( - 2)}^{2} = 4 }}}[/tex]

» Then we add the result to x² and -21

[tex] = { \tt{( {x}^{2} - 4x + 4) + ( - 21 - 4) }} \\ = { \tt{ {(x - 2)}^{2} - 25 }}[/tex]

192/7 or approximately 27.429 ounces

Step-by-step explanation:

Let the amount of water added, in ounces, be [tex]w[/tex]. Set up the following equation:

[tex]\displaystyle \\\frac{64}{64+w}=0.7[/tex]

Multiply both sides by [tex]64+w[/tex]:

[tex]\displaystyle\\64=0.7(64+w)\\64=44.8+0.7w,\\w=\frac{19.2}{0.7}=\boxed{\frac{192}{7}}[/tex]
