The base is 30.
Hopefully I got this correct, not 100%
7/7 = x
3/7 = 240
7/7 x 240 = 240
240/ 3/7 = 560
there is 560 kids
560-240(all kids - girls)
there is 320 boys
Answer:
slope: -2 y intercept: -4 x intercept: -2
Step-by-step explanation:
slope (m) = (-14 -4) / (5 - -4) = -18 / 9 = -2
y intercept (b) = y - mx = 4 - (-2)x(-4) = 4 - 8 = -4
equation: y = -2 x - 4
x intercept: y = 0 x = -2
BD=AC=2CX
2y=2(3y-4)
y=3y-4
2y=4
y=2
$3 because 13-7=6 and 6 divided by 2 equals 3
