Elden [556K]3 years ago
7 0

Answer:

D. -10

Step-by-step explanation:

The sum of a triangle = 180°, therefore,

64° + 63° + x + 63 = 180°

Add like terms

x + 190° = 180°

Subtract 190 from each side

x + 190 - 190 = 180 - 190

x = -10

Marianna [84]

Answer:

A milestone occurring in 3 years of increments of time will be the farthest to the right on a timeline.

Step-by-step explanation:

Here in the given options the increments of time are given.

Here, 3 years > 8 months > 12 weeks > 60 days.

Because, 3 years ≡ (3 × 365) days ≡ 1095 days

8 months ≡ (8 × 30) days ≡ 240 days

12 weeks ≡ (12 × 7) days ≡ 84 days.

Therefore, a milestone occurring in 3 years of increments of time will be the farthest to the right on a timeline. (Answer)

5. (5 points) Write the first 5 terms of the sequence if a1 = 9 and an-1 +n
Ivanshal [37]

Answer:

9,4,-1,-6,-11

Step-by-step explanation:

When n = 1: a(1+1) =a(1) +1

                   a(2) = -9 +1

                   a(2) = -8

When n = 2: a(2+1) =a(2) + 2

                   a(3) = -8 + 2

                    a(3) = -6

When n = 3: a(3+1) = -6 + 3

a(4) = -3
