Solve for x in each of the equations or inequalities below, and name the property and/or properties used:

nordsb [41]

Answer

a) 3/4 x = 9

x = $\dfrac{9\times 4}{3}$

x = 12

b) 10+ 3x = 5x

2 x = 10

x = 5

c) a + x = b

x = b - a

d) c x = d

x = $\dfrac{d}{c}$

e) $\dfrac{1}{2} x - g < m$

$\dfrac{1}{2} x< m + g$

x < 2( m + g)

f) q + 5 x = 7 x - r

q + r = 2 x

$x = \dfrac{q + r}{2}$

5) Alex's house (point F) lies on the same street as her school (point H). Alex's bus stop (point G) lies between her

vlada-n [284]

Answer:

100 meters

Step-by-step explanation:

Given the following :

Alex house = F

Alex school = H

Alex bus stop = G

FG = 2x meters

GH = 1000meters

FH = 1200 meters

Hence,

FH = FG + GH

1200 = (2x + 1000) meters

1200 = 2x + 1000

1200 - 1000 = 2x

200 = 2x

x = 100meters

Hence, x = 100 meters
