if you are evaluating this claim is false
C it’s always c. When in doubt always chose c
Answer:
Total laps = 10d
Step-by-step explanation:
Let c = Carl's laps
d = Daria's laps
e = Erin's laps
c = 3d
c = e/2
c + d + e = totals laps
We can insert 3d in place of c in the third equation
3d + d + e = total laps
Also, e/2 equals 3d
e/2 = 3d
Multiply both sides by 2
(e/2 = 3d)2
e = 6d
Insert the new e
3d + d + 6d = 10d = totals laps
–6x + 2y = 3/2
or, 2y= 6x + 3/2
or, y= (6x + 3/2)/2
or, y = 6x/2 + 3/4
or, y = 3x + 3/4
Therefore, –6x + 2y = 3/2 is Sandra's equation.
Answer:
26.9 inches
Step-by-step explanation:
2x Pythagorean theorem
First we find the length of AC with ABC. AC is the hypotenuse of triangle ABC.
AC = sqrt(7^2+24^2) = sqrt625 = 25.
Now, AD is the hypotenuse of ACD. So AD = sqrt(25^2+10^2) = sqrt(725) = 26.925824 which is about 26.9 inches.
