Which value of y mAkes the equation below true. 3y+8-7y=11
victus00 [196]
We have
3y+8-7y=11
First, we can combine like terms 3y and -7y to get -4y.
Then, we have-4y+8=11 We could then subtract 8 on both sides to get -4y=3
Finally,  we isolate y completely by dividing both sides by -4, to get
y=- \frac{3}{4}

Ghella [55]
Use c^2=a^2+b^2
26^2= 13^2 + b^2
676=169 + b^2 (subtract 169 from both sides)
507= b^2 (take the square root of each side)
22.52 in. =b

O is the center of both circles containing arcs AB and CD
victus00 [196]

Answer:

Step-by-step explanation:

You need to solve the area sector of the bigger circle. Since we now the length of sector is 270, we can set up an equation.  

Length of sector DC = 2\pir

270 = 2\pi(8+OA)                     *(8+OA is the raidus of the bigger circle/sector)*

270/2\pi = 8 + OA  (division)

135/\pi -8 = OA

135/\pi -8 = OB (because OA and OB are the raidus of the same circle, so they are congruent)

I hope this helps you! Please correct me if you see a miscalculation <3<3
