16.19.5
Answer:
Circle circumference = radius * 2 * PI
Arc Length = radius * 2 * PI * Central Angle / 360 degrees
Arc Length = 7 * 2 * PI * (1/4)
= 3.5 * PI
= 10.9955742876
Arc Length = 10.996 (rounded)
Step-by-step explanation:
7 + x/4 = 5 (common denominator is 4)
4(7+x/4) = 4 x 5 (distribute the 4 though parenthesis)
4 *7 +4x/4 = 4 x 5
4 * 7 + x = 4 x 5
28 + x = 4 x 5
28 + x = 20 (subtract the 28)
x = 20 - 28
x = -8
Answer:
9x + 5y
Step-by-step explanation:
Answer:
-36 • (22u + 1)
Step-by-step explanation:
Pulling out like terms :
2.1 Pull out like factors :
-74u - 5 = -1 • (74u + 5)
Equation at the end of step 2 :
(6 • (58u + 1)) - -6 • (74u + 5)
Step 3 :
Equation at the end of step 3 :
6 • (58u + 1) - -6 • (74u + 5)
Step 4 :
Pulling out like terms :
4.1 Pull out 6
Note that -6 =(-1)• 6
After pulling out, we are left with :
6 • ( (-1) * (58u+1) +( (-1) * (74u+5) ))
Step 5 :
Pulling out like terms :
5.1 Pull out like factors :
-132u - 6 = -6 • (22u + 1)
Final result :
-36 • (22u + 1)
