Answer:
x = (ab - ac )/c
Step-by-step explanation:
x/a = b/c - 1 Multiply through by ac:
cx = ab - ac Divide both sides by c:
x = (ab - ac )/c.
1. 6 times 6 = 36 cm
2. 9 times 11 = 99 yd
3. 1/2(13)(8+3)
6.5(11)

4. 12 times 4 = 48 m
5. 5 times 3 = 15 in
6. 8 times 4 = 32 mm
7. 1/2(8)(10+2)
4(12)
48 yd
8. 4 times 4 = 16 cm
9. 12 times 15 = 180 in
Answer:
5 11/12
