Answer:
x = 4
Step-by-step explanation:
(5x+131)° and (5x+19)° are supplementary. Therefore, (5x+19)° + (5x+131)° equals to 180°.
Knowing that, we can do the following:
- (5x+19) + (5x+131) = 180
- 5x + 19 + 5x + 131 = 180
- 10x + 140 = 180
- 10x = 40
- <em>x = 4</em>
Answer:
Step-by-step explanation:
Area = 35*100*2 + 50*100*2 + 50*35*2
= 7000 + 10000 + 3500
= 20500 cm2
Answer:

Step-by-step explanation:
note that 3.28 = 2 × 1.64
This could be a geometric sequence with common ratio r = 2
To obtain the next term multiply the previous term by 2
3.28 × 2 = 6.56
6.56 × 2 = 13.12
1.64, 3.28, 6.56, 13.56 ← first 4 terms in sequence
An answer to this would be y=- 1 over 3 x
