Answer:
2 large trucks = 14 tons of cargo
1 small truck = 3½ tons of cargo
Equation: x + 2x = 10½
Step-by-step explanation:
8 trucks - 4 large trucks, 4 small trucks
small truck = x
large truck = 2x
First, you need to find out how much cargo 1 large truck and 1 small truck can hold.
x + 2x = 10½
3x = 21/2
3x = 10.5
x = 3.5 or 3½
1 small truck can hold 3½ tons of cargo, and 1 large truck can hold 7 tons of cargo.
Next, you need to substitute and find how much cargo 4 large trucks can hold. <em>(Remember: 1 large truck = 7 tons of cargo)</em>
2x
= 2(7)
= 14 tons of cargo
4 large trucks can hold 14 tons of cargo.
Finally, you know that one small truck equals 3½ tons of cargo.
Answer:
85%
Step-by-step explanation:
with OR (as opposed to AND), you add probabilitites
with AND, you multiply them
P(coffee OR food) = .55 + .30 = .85
