Add the expressions 4 minus two-thirds b + one-fourth a and One-half a + one-sixth b minus 7. What is the simplified sum? Negative one-sixth a + StartFraction 5 over 12 EndFraction b minus 3
Three-fourths a minus one-half b minus 3
Three-fourths a + StartFraction 5 over 6 EndFraction b minus 3
StartFraction 5 over 12 EndFraction a minus StartFraction 1 over 6 EndFraction b minus 3

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
