Answer:
8 and 3/10 < 8 and 7/10
Step-by-step explanation:
7/10 is more than 3/10
bearing in mind that
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
so, let's multiply both sides by the LCD of 7 to do away with the denominators
Use the pythagorean theorem. So 4^2 + 7^2 = 10^2. Simplify to 16+49=100. This simplifies to 65=100 which is not true so these sides cannot make a triangle.
Answer:
the minus sign
Step-by-step explanation:
In mathematics, the symbol for the additive opposite is the minus sign
The symbol for the multiplicative opposite is the inverse operation 1/x (I think)
So, yes, specific opposites have symbols, BUT...
Just saying "the opposite of" is too blurry to find one word that represents that.
As you can see, 18 is a constantly repeating number in this situation. So take out the 2.3 to get 0.01818..... To make infinitely long rational numbers with repeating digits into a fraction, put it over 99. so 0.1818...... would be 18/99. But since it is 0.0181818...., you have to put 18 over 990. 18/990 is 2/110, which is 1/55. Now you have to add 2.3 to 1/55 which will be 2 7/22
