True, this is in accordance to the side-side-side postulate.
It is a linear simple equation for one unknown, lets solve it!
-4.2x + 31.5 = -65.1
we can easily get rid of decimals if we multiply the whole equation times 10:
<span>-42x + 315 = -651
</span>-42x = -651 - 315 = -966
x = 966/42
x = 23
that is the solution
Answer:
124
Step-by-step explanation:
15 x 4=60
32 x 2=64
64+60=124
between 30 and 50 is approximately 40
The table on the left is <u>arithmetic</u>
This is because each term is increasing by the same amount (2) each time.
- 3+2 = 5
- 5+2 = 7
- 7+2 = 9
- 9+2 = 11
--------------------------------------------
The table on the right is <u>geometric</u>
Why? Because this time we are multiplying each term by the same value (2) to get the next term.
- 3*2 = 6
- 6*2 = 12
- 12*2 = 24
- 24*2 = 48
Both involve the number 2, but the first table uses addition while the second table uses multiplication.
