a₁ = 4

n = 10

d = 3

a = a₁ + (n - 1)d

a₁₀ = 4 + (10 - 1)3

a₁₀ = 4 + (9)3

a₁₀ = 4 + 27

a₁₀ = 31

The 10th term would be 31 and the d variable will be replaced with the number 3.

Solve for r. You must write your answer in fully simplified form.<br> -20 = -15r
nevsk [136]

Answer:

r = 4/3

Step-by-step explanation:

-20 = -15r

Divide both sides by -15.

-20 / -15 = r

The negatives cancel, so

20 / 15 = r

Simplify by taking 5 out of the numerator and denominator. 20/5 = 4, 15/5 = 3.

4 / 3 = r

<u>So r = 4/3.</u>

3 is a factor of__ A)282 B)187 C)385 D)412​
MrRissso [65]

Answer:

A. 282

Step-by-step explanation:

A trick I know is if you add all the digits of the number and they add up to a multiple of 3, it is divisible by 3.

282:

2 + 8 + 2 = 12

187:

1 + 8 + 7 = 16

385:

3 + 8 + 5 = 16

412:

4 + 1 + 2 = 7
