Answer:

6

Step-by-step explanation:

You have a total area of 2,200 sq units to cover... and each can of paint covers 400 sq units.  So, you'll need:

2200 sq units / 400 sq units/can = 5.5 cans

In such problems, we always round up, since you will need 5 full cans of paint, and half of a 6th can.

So, in total you will need 6 cans of paint to cover all 2,200 sq units.

3) If the speed limit on a highway in the UK is 70 miles per hour and
Afina-wow [57]

Step-by-step explanation:

for this we need to know the conversion rate between miles and kilometers :

1 mile = 1.60934 km

which means

1 km = 0.621371 miles

so,

70 m/h = 70×1.60934 km/h = 112.6538 km/h

compared to the 120 km/h limit in Canada, it is clear that the speed limit in Canada is higher.

the difference is

7.3462 km/h = 7.3462×0.621371 = 4.56471564 m/h

2x+6(2+5x)=92

open the by multiplying every thing in the bracket by 6

2x+12+30x=92

combine the like terms

2x+30x=69212

32x/32=80/32

x=5/2
