Step-by-step explanation:

m∠DCR is an exterior angle of the triangle DCE

Solving For Exterior Angles:

To find the value of an exterior angle, we must sum up the two opposite (corresponding) angles inside the triangle

In this case, 2x + 7 and 26 are the corresponding angles

Solve:

6x - 7 = 2x + 7 + 26

4x - 7 = 7 + 26

4x = 14 + 26

4x = 40

x = 10°

Your answer : x = 10°

JJ withdraws $20 from his bank account every week for lunch. Suppose he does not make any additional deposits or withdrawals. What integer represents the change in value of JJ's bank account after nine weeks?

Answers

Answer:

-118

So,

-20 x 9 = -118

The GCF of two numbers is 3 and the LCM is 180. If the one of the number is 45, what is the other number?

Answers

Answer:

Step-by-step explanation:

45 = 3*3*5

180 = 2*2*3*3*5 <---- so the other number had to contain a factor of 2*2 or 4

also, let the other number has to be of the form 3k and it must contain a factor of 4, how about 12 ?

check: lcf of 12 and 45 is 3,

the lcm of 12 and 45 is ...

12 = 2*2*3

45 = 3*3*5

so we need: 2*2*3*3*5 = 180

10. If you can travel 97 miles in 30 minutes, how many mileScan you
travel at the same rate in 8 hours?

Answers

Answer: 1,552
Explanation: you want to set up a proportion

Ex:

97 X
—- x —
30. 480

The way I got 480 was I converted 8 hours into minutes because you want the same value of measurement.

After this, just cross multiply and you get the equation

46560 = 30mile

Then just isolate the miles (because you are trying to solve for 1 mile

Miles = 1,552

1,552

30 minutes is half of an hour so first you need to multiple 8•2 then you multiple 97 by what 8•2 is (16) that gets you 1552

Answer:

x = 14

Step-by-step explanation:

10x-30+5x = 180

Combine like terms

* 15x-30 = 180

Add 30 from both sides

* 15x 30+-30 = 180+30

Divide 15 both sides

* 15x/15x = 210/15x

x = 14

Step-by-step explanation:

Solve 5x + 2 = 22
Solve 2x-5=7
Solve 2x+5=12

Answers

Answer:

x = 4

x = 6

x = 7/2

Step-by-step explanation:

Solve 5x + 2 = 22:

5x+2-2=22-2 (subtract 2 from both sides)

5x=20

x=4

Solve 2x-5=7

2x-5+5=7+5 (add 5 to both sides)

2x=12

x=6

Solve 2x+5=12

2x+5-5=12-5 (subtract 5 from both sides)

2x=7

x= 7/2

Solve 5x + 2 = 22

=> 5x + 2 = 22

=> 5x = 22 – 2

=> 5x = 20

=> x = 20/5

=> x = 4

Solve 2x-5=7

=> 2x - 5 = 7

=> 2x = 7+5

=> 2x = 12

=> x = 12/2

=> x = 6

Solve 2x+5=12

=> 2x + 5 = 12

=> 2x = 12-5

=> 2x = 7

=> x = 7/2

Answers

Step-by-step explanation:

The interior angles of a triangle add up to 180 degrees.

90 + 2x + (3x - 20) = 180

90 + 2x + 3x - 20 = 180

70 + 5x = 180

5x = 110

x = 22

2(22) = 44
