Answer:
k = 4
Step-by-step explanation:
Hello!
3k + 16 = 8 + 5k
Subtract 3k from both sides
16 = 8 + 2k
Subtract 8 from both sides
8 = 2k
Divide both sides by 2
4 = k
The answer is 4

Answer:
Step-by-step explanation:
There are 50 hundreds in 5000.
No of defective bulb expected = 50 * 3 = 150
The answer would be -4 and 4
12 x 5.2
Estimate:
since 5.2 is about 5, we can estimate this to:
12 x 5 = 60
Find the Product:
12
<u> x 5.2
</u> 2 4
<u> + 6 0 0
</u> 6 2 4
now add the decimal back in. In the original problem there is one decimal place (the .2 in 5.2) so we move the decimal place one over in our product
624 becomes 62.4
Answer:
100
Step-by-step explanation:
I believe you meant x^2 - 20x; " ^ " denotes exponentiation.
Take half the coefficient of the x term (which in this problem is -20). We get -10. Now square this, obtaining 100.
Adding 100 to x^2 - 20x "completes the square."
