There are 5376 squares on all of the chessboards because 84 x 64= 5376
Answer:
x= 27
Step-by-step explanation:
Move <u>constant</u> to the right-hand side and change its sign.
= 2+6
Add the numbers.
= 8
Square both sides of the equation.
2x+10= 64
Move the <u>constant</u> to the right-hand side and change its sign.
2x= 64-10
Subtract the numbers.
2x= 54
Divide both sides of the equation by 2.
x= 27
Answer:
ok
Step-by-step explanation:
your question is too long plz make it short i don't have so much time to ans it fully okay?
3 is 15% of what number...
3 = 0.15x
3/0.15 = x
20 = x
Let the extensions of secants AD and BC meet at point P.
Let the measure of ar DC be 2a, then m(DAC)=m(DBC)=a, since angles DAC and DBC are both inscribed angles intercepting arc DC.
m(P)=b.
Then triangles APC and BPD are similar, because they have 2 pairs of common angles.
from the similarity of APC and BPD, we can write the ratios:
