Answer:
And we can subtract 4x in both sides and we got:
Now we can subtract in both sides 16 and we got:
And if we divide both sides by 4 we got:
And the best solution would be:
-7
Step-by-step explanation:
For this case we assume the following equation:
And we can subtract 4x in both sides and we got:
Now we can subtract in both sides 16 and we got:
And if we divide both sides by 4 we got:
And the best solution would be:
-7
X=6-58
X=(-52)
You use the inverse operation to get X by itself.
Answer:
m∠B = 
.
Step-by-step explanation:
Since the three sides of the triangle are given, then we apply cosine rule.
= 
+ 
- 2ac Cos B
But, a = 660 cm, b = 680 cm, and c = 100 cm.
So that;
= 
+ 
-2(660 x 100) Cos B
462400 = 435600 + 10000 - 132000 Cos B
462400 = 445600 - 132000 Cos B
132000 Cos B = 445600 - 462400
= -16800
Cos B = 
= -0.1273
B = 
-0.1273
=
Thus, measure of ∠B is .
638 divided by 11= 58. 58x9=522
Okay, after I explain the process of finding the answer to this, it will be easier for you! First, you shold understand the key words to math. In this question, fewer is the key word. And fewer means less, so subtraction. Every new row has 2 FEWER tiles than the row below it. So we now to to subtract 2 from EVERY NEW row. So, if the first row has 23 tiles how many tiles will be in the next row. Well, all we have to do is 23 - 2 = 21! There is your answer, I hope I am correct!
(It is your choice to go with my answer being correct or not. I absolutely WILL NOT, and CAN NOT take responsibility for your question being incorrect. Again, it is YOUR choice to choose whether or not you go with my answer. Thank you!) :)
