Answer:
x = 80
Step-by-step explanation:
In a quadrilatoral the interior angle sum always adds up to 360 degrees so to find x you would add all of the interior angle sums and subtract that from 360
115 + 95 + 70 + x = 360 just add the like terms
280 + x = 360 now subtract 280 from both sides so x is alone and you can figure out its value
x= 80
90 divided by X (x is the number of friends which the question did not provide)
Answer:
1. Number of warts on a toad ⇒ <em>discrete variable</em>
2. Survival time after poisoning ⇒ <em>continuous variable</em>
3. Temperature of porridge ⇒ <em>continuous variable</em>
4. Number of bread crumbs in 10 meters of trail ⇒ <em>discrete variable</em>
5. Length of wolves’ canines ⇒ <em>continuous variable</em>
A discrete variable is the one which takes over range of real number, for a value in range that variables are permitted to take, there is minimum distance to nearest permissible value. In contrast, continuous variables are the one which can take infinitely many values.
No...standard form cannot have fractions
2/3x - 1/3y = 2....multiply by common denominator of 3 to get rid of fractions
2x - y = 6 <== standard form
