<em>Identify</em>
0.8k - 20 = -60
<u>Step 2: Solve for </u><em><u>k</u></em>
- [Addition Property of Equality] Add 20 on both sides: 0.8k = -40
- [Division Property of Equality] Divide 0.8 on both sides: k = -50
Answer:
9²
Step-by-step explanation:
9 × 9 = 81
Nine to the power of Two
It is 7
2*2x = 4x + 2 = 30
4x = 28
x = 7
Answer:
First term a = 41
Step-by-step explanation:
Arithmetic Progression:
Common differences d = -2
= 10*(2a - 38)
= 10*2a - 10*38
=20a - 380
= 11 (2a -42)
=11*2a - 11*42
= 22a - 462
22a - 462 = 20a - 380
22a = 20a - 380 + 462
22a = 20a + 82
22a - 20a = 82
2a = 82
a = 82/2
a = 41
First term a = 41
