ZB is 3x-5 BA is x+3

Akimi4 [234]

If B is the midpoint of ZA, then ZB = BA
3x-5 = x+3
3x - x = 3 + 5
2x = 8
x = 8/2
x = 4

ZA = ZB + BA
= 3x-5 + x+3
= 3*4 - 5 + 4 + 3
= 12 - 5 + 7
= 14

Answer:

7.211103

Step-by-step explanation:

For:

(X1, Y1) = (-3, 4)

(X2, Y2) = (1, -2)

Distance Equation Solution:

d=(1−(−3))2+(−2−4)2−−−−−−−−−−−−−−−−−−−√

d=(4)2+(−6)2−−−−−−−−−−√

d=16+36−−−−−−√

d=5–√2

d=7.211103

Answer:

$325

Step-by-step explanation

78% is 234

x is 100%

cross multiply

$\frac{234}{72}$ = $\frac{x}{100}$

234 × 100 = 72x

23400 = 72x

23400÷72 =72x ÷72

325 = x
