Answer 1

Answer:

b) 50 degrees

Step-by-step explanation:

I'm not sure if it 100% correct but this is what i remember:

BCE is a straight line and a straight line is equal to 180 degrees.

If AB=AC then the angle of both those corners will be 180-115

which equals to 65 degrees (both angles)

Now because all corners of a triangle add up to 180

you can do 180-65-65 which is 180-130

this equals to the angle BAC which is 50 degrees

What is the regular monthly rate for each phone?​

Answers

Answer:

22.45

Step-by-step explanation:

ixl told me a

Answer:

$22.45 per month

Step-by-step explanation:

Fred's family will pay for cell service for 5 phones at a regular monthly rate of c dollars for each phone. They will also receive a discount of $50. The first month's payment will be $62.25. This equation represents the situation.

5c

−

50

=

62.25

monthly cost of cell service for 5 phones

one-time discount

first month's payment

Now, solve the equation for c.

5c–50

= 62.25

5c

= 112.25 Add 50 to both sides

c

= 22.45 Divide both sides by 5

The regular monthly rate for each phone is $22.45.

(b) It takes 37 pounds of seed to completely plant a 4-acre field. How many pounds of seed are needed per acre?​

Answers

Answer:

9.25 lbs

Step-by-step explanation:

37 is the amount for 4 acres or 4a:

37  = 4a

Isolate and find a by dividing both sides by 4:

4a = 37

4a ÷ 4 = [tex]\frac{37}{4}[/tex]

a = [tex]\frac{37}{4}[/tex] or 9.25 lbs

Please help out:/

Answers

Answer:

Step-by-step explanation:

The triangle’s angles add up to 180°

so 180 - (5x - 2) = the another one interior angle

180 - 5x + 2

182 - 5x

and then 2x + 76 + (182 - 5x) = 180

2x + 76 + 182 - 5x = 180

258 - 3x = 180

78 = 3x

x = 26

so 2x = (26)(2) = 52

5x - 2 = (5)(26) - 2 = 128
