Answer:
x = 7cm
Step-by-step explanation:
About 6 to 12 gallons per minute
Note: 1 inch = 2.54 cm is an exact converion, while 1 mile=1.6km is only approximate.
Using conversion
1 inch=2.54 cm
1 mile = 1760*3*12 = 63360 in = 160934.4 cm
If 1 inch = 1 mile, then
2.54 cm : 1 mile = 1.609344 km
1 cm : 0.6336 km (exactly), or
1 cm : 0.6 km (approximately)
Using both conversions:
1 inch = 2.54 cm : 1 mile = 1.6 km
=>
2.54 cm : 1.6 km
1 cm : 1.6/2.54=0.6299 km (approximately), or
1 cm : 0.6 km (approximately)
Answer:x=5
Step-by-step explanation:
4x - 10 = 0.5x + 7.5
-0.5x -0.5x
3.5x - 10 = 7.5
+10 +10
3.5x = 17.5
divide both sides by 3.5 and you get x=5
