Step-by-step explanation:
The 'braces' don't really matter in this equation, it is all multiplication, just open those bad boys up and you get 4*2*7=4*2*? Now it is much easier, just take the value missing from the left side and you find it is 7!
Answer:
x=72
y=54
Step-by-step explanation:
1st question. y=54 because it is a bisector of the 108 degree angles. (a polygon's interior angles add to number of sides minus 2 times 180)
There are two ys, so they add up to 108. A triangle's interior angles add to 180. 180-108 =72 x=72
2nd question, x is 72 ( it says x is the same measure) so 180-72=2y.
y still equals 54
Add the numbers up to get the total number of biscuits, which will be 50. Then, make a fraction using the squares, which will be 15/50. Simplify by 5. The answer will be 3/10.
I hope this helped!
