What does x equal? angle2 = (20x - 1), and angle3 = (4x + 13)

Mathematics
1 answer:
Maurinko [17]3 years ago
3 0

Answer:

x = 7

Step-by-step explanation:

angles 2 and 3 form a straight angle and are supplementary, that is they sum to 180°, hence

∠2 + ∠3 = 180 ← substitute values

20x - 1 +4x + 13 = 180

24x + 12 = 180 ( subtract 12 from both sides )

24x = 168 ( divide both sides by 24 )

x = 7

guajiro [1.7K]

Answer:

t/8 + t/7 = 1

Step-by-step explanation:

Given in the question that,

time require for Jose to paint the house = 7 hours

time require for Brandon to paint the house = 8 hours

Suppose t means Full house painted.

<h3>To solve the question we have to figure out how much each of them can paint in ONE hour.</h3>

7 hours----t

1 hour ---- t/7

8 hours----t

1 hour ---- t/8

<h3>Equation</h3>

t/8 + t/7 = 1 (in one hour)

(7t + 8t)/8(7) = 1

15t/56 = 1

15t = 56

t = 56/15

t = 3.73 hours
