Kate solved the inequality problem below incorrectly. Explain her error and redo the problem showing the correct answer.
Original problem: -3x+4<16
Kate’s math work: -3x+4-4<16-4
-3x÷-3<12÷-3
x<-4

Original problem: -3x+4<16

-3x÷-3<16÷-3

x<-4

Kate’s math work: -3x+4-4<16-4

-3x÷-3<12÷-3

x<-4

she changed 16 to 12

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
