Answer:
137
Step-by-step explanation:
The degrees of the inscribed arc of 43 is 43 * 2 = 86
Since the total degrees in a circle is 360, x is equal to
(360-86)/2 = 137
We are given equation: 34b−23b=−9.
We can see 34b and 23b both has b's with them.
So, we can combine like terms.
Comining means addition or subtaction.
We have minus sign in between 34b and 23b.
So, we need to subtract 34b and 23b.
On subtracting, we get
11b.
Therefore, we get
11b = -9.
Now, we need to divide by 11 on both sides. We get on dividing
b = -9/11.
Therefore, -9/11 can be enter in the boxes to write an equation that is equivalent to 34b−23b=−9.
5/14+1/6=5*3/42+1*7/42=15/42+7/42=22/42=11/21
Answer: 7a
Step-by-step explanation: Since they are like terms, you can just add or subtract them.
4a - 5a = -1a
2a + 6a = 8a
-1a + 8a = 7a
