If we know that line
is equal to line
, then this means that ∠
has to be equal to ∠
in order to form a closed triangle. All angle measures of a triangle add up to
°, so use the equation:
.
70 + x = 180
Subtract 70 from both sides to isolate x:
180 - 70 = 110
110 = x
Hope this helped.
Answer:
6.23*10^6
Step-by-step explanation:
We first write the answer in full notation 6,230,000.
Then we count how many decimal places it takes before we have one leading digit. Since it is six, we move the decimal place and write 6.23*10^6
Answer:
n>9
Step-by-step explanation:
4(n-3)- 6 > 18
To solve this inequality we need to remove the parenthesis
distribute 4 inside the parenthesis
4n -12 - 6 > 18
Now combine like terms
4n - 18 > 18
We need to isolate 'n', so we add 18 on both sides
4n > 36
Now divide both sides by 4
n > 9
So the value of n is greater than 9
The number next to a variable, for example: 5x, is called a coefficient. And all you do is multiply the number with the variable
