A squared + B squared= C squared
I am not sure if it is working at present.
Something like this might be better

−48t+2≤−71t+14
\(−48t+2≤−71t+14 \qquad \text{next add 71t to both sides}\\ 23t+2≤14 \qquad \text{ next -2 to both sides}\\ 23t≤12 \qquad \text{ next -2 to both sides}\\ t\le12/23\)
what is x to the negative power of 7
\(x^{-7}=\frac{1}{x^7}\)
Whatever happened to please?
Two common envelopes sizes are 3 1/2 in. times 6 1/2 in. and 4 in. times 9 1/2. Are these envelopes similar? Explain.
6.5/3.5 = 1.8571428571428571
9.5/4 = 2.375
NOT the same answer.
The sides of the rectangle are NOT in the same ratio so the envelopes are NOT a similar size.
You just wrote a question in a box so I guess it does work.
You even have an answer so I guess it works twice as well.
12/10 =1.2 - 1 = 0.2 x 100 = 20%
150 = 2×3×5^2 (4 prime factors, 3 distinct)
315 = 3^2×5×7 (4 prime factors, 3 distinct)
PPCM = 3,150
10,000 = 5^x
x = Log(10,000) / Log(5)
x = 5.7227 or just under 6x.
5 > 25 > 125 > 625 > 3,125 > 10,000
dived by the number and in this calculater you do fractions like this (2)(54)<---------
You subtract the 7 on the left. 12-7=5. The equation left is -3x=5, divide 5 by -3 and -3 by itself. This cancels out the -3, making the answer -5/3 because the denominator can never be negative. So you move it up.
x=12
Never because there is one person who has no friends and no one tells him/her anything.
The rest just get told over and over again until the next bit of exciting trivia comes along.

were these the right answers?
Answer is -39.
Hi Darkness,
$50 more than 125%
This question does not make sense.
You could say
What is 125% of $50 1.25*50= $62.50
or you could say
Increase $50 by 25% which means 50 + 0.25*50 = $62.50
See those two things are the same :))
I found a slight error in your answer.
When you added 48, It should be 108 instead of 12.
So the answer should be k=-9 instead of k=-1.
The answer is .67 in decimal form or 2/3 in simpliest form.
divide 3 into 5
-12(k+4)=60
\(-12\times(k+4)=60\)
\(-12k-48 =60\) \([ \ +48\)
\(-12k =12\) \([ \ /-12\)
\({\color{blue}k=-1}\) !
