Answer:
-y + 63
Step-by-step explanation:
Let's start like by solving the order of operations, and then add our Y's:
7y + 7 + −8y + 56
Adding:
+63 - y
Simplifying:
-y + 63
Thus, our answer is -y + 63
26)
the sum of all internal angles=(sides-2)*180
720=(x/25-2)*180
4=x/25-2
6=x/25
150=x degrees per angle of A
use angle of A to calculate amount of sides of A:
150=(n-2)*180/n
150=180-360/n
360/n=30
12=n=sides of A
-> F

Donald=500-6*t
Wendy=400-4*t
W=D
500-6t=400-4t
100-6t=-4t
100=2t
50=t
-> A
Answer:
5
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 10^2 = (5 sqrt(5))^2
a^2 +100 = 25(5)
a^2 +100 = 125
a^2 = 125-100
a^2 = 25
Taking the square root of each side
sqrt(a^2) = sqrt(25)
a = 5
