The last one are like terms because they can combine.
x = 73.21
Step-by-step explanation:
Consider triangle ABC. Since angle A is 45° and side BC is 100, then side AB is also 100.
Now consider triangle ABD. With angle A equal to 60°, we can use the definition of tangent to find the value of x:
tan 60 = BD/AB
sqrt(3) = (x + 100)/100
or
x + 100 = 100sqrt(3)
x = 100[sqrt(3) - 1]
= 73.21
The word "of" is the same thing as a multiplication sign!
So instead see it this way:
53% × 470
To solve this, you can use the cross product method :
=
(470 × 63) ÷ 100 = ?
29 610 ÷ 100 = ?
296.1 = ?
53% of 470 is 296.1
There you go! I really hope this helped, if there's anything just let me know! :)
The value of x is 5.5. I got this answer by first distributing -3 amongst (x-11), and distributing 7 amongst (2x-5). Next I combined like terms and subtracted 3x from 5x, and added -35 and 2. Next I subtracted 33 from both sides. Next I subtracted 14x from both sides. And finally I divided both sides by -12 to get the final answer of 5.5.
but good luck
