≈80 (possible answer)
C = 15n + 85....when C = 385
385 = 15n + 85
385 - 85 = 15n
300 = 15n
300/15 = n
20 = n <== 20 watches were made
2, 1, 3 ,6. A Great way to get factors are by using a calculator and add up
2.2 x 10 to the 5th power.
Answer:
Step-by-step explanation:
Sum of all angles of a triangle = 180
x + 64 + x + 45 + 79 = 180
Combine like terms.
2x + 188 = 180
2x = 180 - 188
2x = - 8
x = -8/2
x = -4
x + 64 = -4 + 64 = 60
x + 45 = -4 + 45 = 41
