Explanation:

Let y be the unmarked angle to the right of (x+85). Since angle (x+85) and angle y form a straight angle, we know that (x+85)+y = 180.

We also know that y = 60 since line a is parallel to line b, and corresponding angles are congruent when we have parallel lines.

So (x+85)+y = 180 updates to (x+85)+60 = 180

-------

Let's solve for x

(x+85)+60 = 180

x+85+60 = 180

x+145 = 180

x = 180-145

x = 35

Answer:

3(2x+5)

2*x + 5=15

3*15=45

Answer:

√185 = 13.6

Step-by-step explanation:

Distance² = (x' - x)² + (y' - y)²

Distance² = (-7 - 4)² + (5 - -3)² = (-11)² + (8)² = 121 + 64 = 185

Distance = √185

Please check explanations

Step-by-step explanation:

Mathematically;

csc 2 theta = 1 / sin 2 theta

Sin 2 theta = sin (theta + theta)

= 2sin theta cos theta

So therefore;

csc 2 theta = 1/2(sin theta cos theta)

= 1/2 * 1/sin theta * 1/ cos theta

1/sin theta = csc theta

1/cos theta = sec theta

Thus;

csc 2 theta = 1/2 * csc theta * sec theta

csc 2 theta = 1/2 sec theta csc theta

A is the answer for this problem

Answer:

49, first option!

Step-by-step explanation:

Ok before we get started we need to know that: negative x negative is a negative.

1. Make them into improper fraction.

-35/3 x (-21/5)

2. Multiply.

-35/3 x (-21/5)=-35/3 x -21/5 = 735/15=49

Hope this helps :)

Step-by-step explanation:

Answer:

y = a(1 + r) ^v

y = 6200( 1 + 0.05)^v

y = 6200(1.05)^v

Step-by-step explanation:

Fred purchased a piece of artwork for 6200, and it is expected to increase in value by 5% per year. Write a function y to represent the value of the piece of artwork after v years.

The function we can used to represent the above question is given as Exponential Growth function.

Where the number of years = v

The value of the artwork = y

y = a(1 + r) ^v

Where

a = Initial value of the artwork = 6200

r = Growth rate = 5% = 0.05

v = number of years

Therefore, the function y to represent the value of the piece of artwork after v years is written as:

y = 6200( 1 + 0.05)^v

y = 6200(1.05)^v

Answer: 9 - 8n

A - B = -3n + 2 - (5n - 7) = -3n - 5n + 2 + 7 = 9 - 8n

Answer:

0.08

Step-by-step explanation:

Answer:

x=? y=?

y=13-3x

5x+(13-3x)=21

5x+13-3x=21

2x+13=21

2x=21-13

2x=8

x=8/2

x=4

20+y=21

y=21-20

y=1

The correct answer is 3: 35

Explanation:

To calculate at what time Jenny will arrive in Rochefort, the first step is to calculate the approximate time of the trip. Now, to calculate this consider the time of a movement (t) equals to the distance (d) divided by the speed (s), the process is shown below:

t = 483 km / 84 km/h

t = 5.75 hours

In this number 5 refers to the hours and 0.75 represents 45 minutes considering 0.75 x 60 minutes in one hour = 45 minutes. Therefore, the total time from Paris to Rochefort is 5 hours and 45 minutes. Now, to calculate the time of arrival add this result to the time of departure.

Add the hours: 5 hours + 9 hours: 14 hours

Add the minutes: 50 minutes + 45 minutes =95 minutes

95 minutes are equivalent to 1 hour (60) minutes and 35 minutes

Calculate the total

Hours: 14 hours + 1 hour = 15 hours or 3  in the 12 hour system (15 hours - 12 hours = 3 p.m.)

Minutes: 35 minutes

Answer:

6 weeks

Step-by-step explanation:

Given that :

Nikki :

Initial amount = $1100 ;

Amount spent per week = $35

Mich:

Initial amount = $520

Amount saved per week = $55

Number of weeks they'll both have the same amount :

Let number of weeks = w

For Nikki who is spending :

1100 - 35w - - - (1)

For Mich who is saving :

520 + 55w - - - (2)

Equate (1) and (2)

1100 - 35w = 520 + 55w

1100 - 520 = 55w + 35w

580 = 90w

w = 580 / 90

w = 6.444

Answer

The tool set costs $68 during the sale this week.

Explanation

We know that...

Normally the tool set costs $80.

During the sale, the tool set costs $12 less than usual.

So you should subtract to find the cost of the tool set during the sale.

80-12=68

So the tool set would cost $68 during the sale.

Step-by-step explanation:

First one is -12

Second one is -29
