No solution because -3a +3a is cancelled out and 6 does not equal 7
This problem involves finding arc lengths. The formula for arc length
is s = r*theta, where r is the radius and theta the central angle.
In 15 minutes, the minute hand sweeps out 1/4 of a circle, or pi/2 radians. This is the central angle. The arc length (how far the minute hand moves in 15 min) is then
s = (6 inches)(pi/2 rad) = 3pi inches, or about 9.42 inches.
25 minutes is equivalent to a central angle of (25/60)pi rad, or 1.31 radians. What is the associated arc length? Calculate this in the same way as I did for a central angle of pi/2.
To find out the answer,we can test it out one by one:
The original expression: 6×(2+8)=60
A. 6x(8+2)= 6x10 = 60✅
B. (6×2)+8 = 24+8 = 34
C. (8+2)x6 = 10×6 = 60✅
D. 6x2÷6×8 =12÷6×8 = 2×8 = 16
As A. and C. equals to the original expression, the answer is A. and C.
Answer:
4w+10=-w
w=-2
Step-by-step explanation:
First, write out the equation in the algebraic form to make it easier to solve. This equation written out is 4w+10=-w. Then, isolate the variable and solve. Do this by subtracting 4w from both sides. Then, divide both sides by -5.
