All really need to do is pick one number. so, we will go with 6 and 87.
6 times 12 is 72 then you subtract that from $87.
That would be 15
To double check, you can use another one. 9 and 123.
9 times 12 is 108. subtract that from 123 and you get 15.
Your answer is B) $15
Hope I helped :)
Answer:
(-3, -4)
Step-by-step explanation:
y= -4
so you plus y in for the y=2x+2 equation where you get x=-3
Answer:
x = 13/8
Step-by-step explanation:
sqrt(8x-4) +8 = 11
Subtract 8 from each side
sqrt(8x-4) +8-8 = 11-8
sqrt(8x-4) =3
Square each side
(sqrt(8x-4))^2 =3^2
8x-4 = 9
Add 4 to each side
8x-4+4 = 9+4
8x = 13
Divide by 8
8x/8 = 13/8
x = 13/8
Answer:
ow do you find arc length without the radius?
To calculate arc length without radius, you need the central angle and the sector area:
Multiply the area by 2 and divide the result by the central angle in radians.
Find the square root of this division.
Multiply this root by the central angle again to get the arc length.
The units will be the square root of the sector area angle.

Or the central angle and the chord length:
Divide the central angle in radians by 2 and perform the sin function on it.
Divide the chord length by double the result of step 1. This gives you the radius.
Multiply the radius by the central angle to get the arc length.
