Distance on bus: 2.85 x 1000= 2850m

Total distance= 320m + 2850m

= 3170 m

Pam's method

Distance to bus stop = 320 ÷ 100 = 0.32 km

Total distance= 0.32 km + 2.85 km

= 3.17 km

Explain the best you can because I’m struggling :)

Zigmanuir [339]

Step-by-step explanation:

A. 3x+4/2 = 9.5

3x + 4/2 = 9.5........criss cross

3x+4= 9.5×2

3x = 19-4

3x = 15

x=5 ..........divide both sides by 3

B. 7+ 2x/3= 5.......criss cross

7+2x = 5 × 3

7 + 2x = 15

2x = 15-7

2x = 8......divide both sides by 2

x = 4
