I am given that p || q. ∠1 and ∠4 are supplementary angles because they form a linear pair, so m∠1 + m∠4 = 180°. ∠4 and ∠8 are also supplementary because of the Same-Side Interior Angles Postulate, so m∠4 + m∠8 = 180°. You can substitute m∠4 + m∠8 for 180° in the first equation above. The result is m∠1 + m∠4 = m∠4 + m∠8. After subtracting m∠4 from each side, I see that m∠1 = m∠8.

Answer:

With like terms the answer is x = 5/2

Step-by-step explanation:

First we find the value of [tex]x[/tex]. This is quite simple as it's a right angled triangle with one of the angles already given. The main concept is vertically opposite angles meaning if 2 lines intersect, the opposite 2 angles are equal.

So the angle [tex]55x - 1[/tex] is for the interior of the triangle too. Now due to angle sum postulate, [tex]36x + 55x -1 + 90 = 180[/tex]

Simplify this and you get: [tex]91x = 91[/tex]

Hence, [tex]x = 1[/tex]

Now, we need to find the value of angle [tex]A[/tex] which is [tex]36x[/tex] which is basically [tex]36 * 1[/tex] when we replace [tex]x[/tex] with [tex]1[/tex].

Henceforth, angle [tex]A[/tex] is equal to [tex]36[/tex] so option [tex]C[/tex] is correct. :D

===================================================

Explanation:

Place point B at the intersection of the lines where the 90 degree angle is located.

Place point C at the other intersection point.

So we have triangle ABC.

Since we have a right angle, this means angle B is 90 degrees.

Angle C is 55x-1 degrees because it's vertical to the angle shown. Vertical angles are congruent.

See the diagram below.

-------------

From here we use the idea that all three angles of any triangle always add to 180

A+B+C = 180

(36x) + (90) + (55x-1) = 180

91x+89 = 180

91x = 180-89

91x = 91

x = 91/91

x = 1

Use this x value to find angle A and C

A = 36x = 36*1 = 36

C = 55x-1 = 55*1-1 = 54

Finding angle C is optional since your teacher just wants angle A, but it's useful to help check our answer

A+B+C = 36+90+54 = 180

So this confirms we have the right x value.

Answer:

1 rose cost $1.5

1 carnation cost $0.5

Step-by-step explanation:

Let the price for one rose be r, price for one daisies be d and the price for one carnation be c

For Ben;

5r + 8d + 2c = 14.5

For Alex

3r + 12d + c = 14

For Joe

10r + d + 3c = 17.25

From equation iii;

d = 17.25- 10r - 3c

Insert this into the first two equations;

5r + 8(17.25-10r-3c) + 2c = 14.5

5r + 138 - 80r -24c + 2c = 14.5

-75r -22c = -123.5

Thus;

75r + 22c = 123.5

Insert the formula for d in the second equation;

3r + 12(17.25-10r-3c) + c = 14

3r + 207 - 120r -36c + c = 14

-117r-35c = 14-207

117r + 35c = 193

So we have two equations to solve simultaneously;

75r + 22c = 123.5

117r + 35c = 193

Multiply first equation by 35 and second by 22

2625r + 770c = 4322.5

2574r + 780c = 4246

Subtract second from first

51r = 76.5

r = 76.5/51

r = 1.5

Insert this in the equation below;

75r + 22c = 123.5

75(1.5) + 22c = 123.5

112.5 + 22c = 123.5

22c = 123.5-112.5

22c = 11

c = 11/22

c = 0.5

Answer:

B

Step-by-step explanation:

Step-by-step explanation: The first thing you're going to probably

try to do here is to factor out a greatest common factor.

The problem is, there is no factor that is in common

to all three of these terms so you may think it's unfactorable.

However, this trinomial is in a special form.

We have an x squared term, an x term, and a constant term.

When a trinomial is in this form, it can be

factored as the product of two binomials.

So start by setting up two sets of parentheses.

Inside each set, we will have the two terms that compose each binomial.

So we have (    )(    ).

The first term is a factor of the x² term, x · x.

For the second term, we need factors of 12 that add to -7.

Since the middle term is negative, we use the negative factors of 12.

Notice that -4 and -3 add to -7 and multiply to be 12.

So our answer is (x - 4)(x - 3).

Yeah also you got it correct, congrats.

Answer:

where is the question ??

Answer:

The equation is: y=(x-45)/3 and Beth can ride the bus 118 times.

Step-by-step explanation:

From the information provided, the total cost of riding the bus is equal to the start-up fee plus the cost of each ride for the number of times Beth rides the bus:

x=45+3y, where x is the total cost of riding the bus and y is the number of times Beth rides the bus.

Now, you can solve for y and you can replace x with 400 that is the total amount Beth has:

x=45+3y

y=(x-45)/3

y=(400-45)/3

y=355/3

y=118

According to this, the answer is that the equation is: y=(x-45)/3 and Beth can ride the bus 118 times.

Answer:

Part A  The 4th bubble y= -55x+1630

Part B 1630

Part C 55

Step-by-step explanation:

Part A Use slope to find answer. In this example, points (1,599) and (4,1430).

Next use equation y1-y2/x1-x2. In this example, 1599-1430/1-4  which equals 169/-3 and that equals -56.3333333333333333333333.  Since y= -55x+1630 is closer, choose that answer.

Part B use y intercept. The y intercept is 1630

Part C Use the slope -55. It decreases by 55.

Answer:

y = - 3x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + y + 2 = 0 ( subtract 3x + 2 from both sides )

y = - 3x - 2 ← in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes, thus

y = - 3x + c ← is the partial equation

To find c substitute (3, - 4) into the partial equation

- 4 = - 9 + c ⇒ c = - 4 + 9 = 5

y = - 3x + 5 ← equation of line in form y = mx + c

The equation of line which parallel to given line is, [tex]y=3x-8[/tex]

The equation of line in slope intercept form is,

                            [tex]y=mx+c[/tex]

Where m is slope of line and c is y-intercept.

Equation of line given that,

                            [tex]y=3x+4[/tex]

So that, slope of line is [tex]3[/tex]

We have to find the equation of the line that passes through (4,4) and is parallel to given lines.

Since, slope of all parallel lines are same.

Equation of required line is,

                          [tex]y=3x+c[/tex]

Substitute point (4,4) in above line.

                        [tex]4=12+c\\\\c=4-12=-8[/tex]

So that, equation of line become,

                       [tex]y=3x-8[/tex]

Answer:

3 5/8 inches of snow per hour

Step-by-step explanation:

29 divided by 8 = 3.625

if 29 inches for 8 hours, and you need to find how much snow in one hour, you can get 1 hour from 8 hours by doing 8 divided by 8. You  use the same number to find the snow, divide 29 by 8 and you get the rate at which snow builds up.

Step one:

He charged $25 and spent $6 on gas on Monday.

then he made 25-6= $19 mowing his neighbor's lawn.

the next day is Tuesday(we are not told he spent any amount on gas on Tuesday).

So he mowed his Grandparents yard for $20.

total money saved for Monday and Tuesday is
