Answer:
Step-by-step explanation:
Let:
So, rewritting the equation:
Factoring:
Therefore:
Substitute back for
for y=2
Taking the logarithm base 10 of both sides:
for y=1
Taking the logarithm base 10 of both sides and adding 1 to both sides:
so:
Hence:
Answer:
43.98
Step-by-step explanation:
i was doing a problem like that on my math paper as well
First, let's talk about how many eggs there are in a dozen.
1 dozen of anything = <em><u>12</u></em> of them .
Now, armed with that vital piece of information, let's do the problem.
Give Uncle Wilbert's age a name. Call it ' A '. (for 'age')
If you divide it by 4, you then have A/4 .
Then if you subtract 11 from that number, you have A/4 - 11 .
Now we can write an equation: A/4 - 11 = 12
Add 11 to each side of the equation: A/4 = 23
Multiply each side of the equation by 4 : A = 92 .
<u>Uncle Wilbert is 92 years old</u>.
<em><u>Proof:</u></em>
Divide it by 4 and you have 23 .
Then subtract 11 and you have 12 ... the number of eggs in a dozen.
60/100. Divide by 10: 6/10. Divide by 2: 3/5. She read 3/5 of the book :)
Hey there! I'm happy to help!
We see that points A and B are on the same horizontal line, and and they are 10 units apart. C and D are on their own horizontal line and they are also 10 apart. This means that this is a square, so we multiply one side by itself
10²=100
The area is 100 square units.
Have a wonderful day! :D
