Step-by-step explanation:
it all starts with the understanding that "midpoint" means that the line segments on both sides have the exact same length.
this is the same as "cut a pizza or a cake in half".
therefore, we know
10x + 1 = 8x + 13
2x + 1 = 13
2x = 12
x = 6
AB = 10x + 1 = 10×6 + 1 = 60 + 1 = 61
BC = AB but to control : 8×6 + 13 = 48+13 = 61
correct.
AC = AB + BC = 61 + 61 = 122
Answer: 4.26 x 10^2
Step-by-step explanation: you need to move the decimal over 2 spots because it needs to be a number from 1-9. So it would be 4.26. Then the exponent is positive 2 because you are moving the decimal to the left.
34.95 x 18%= 6.29
34.95-6.29= 28.66
$28.66 is the sale price
Answer:
$261.80 Net pay
Step-by-step explanation:
340 x 0.23 = $78.20 in taxes
$340 - $78.20 = $261.80 Net pay
D = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
d = sqrt( (5 - 2)^2 + (7 - 3)^2 )
d = sqrt( 3^2 + 4^2 )
d = sqrt(9 + 16)
d = sqrt(25)
d = 5
