Adrian's car gets about 12.5 kilometers per liter. He is planning a 1,600 kilometer trip. a) About how many liters of gas should Adrian plan to buy? Round your answer to the nearest liter.

b) At an average price of $0.90 US per liter, how much should Adrian expect to spend for gas?​

try multiplying how much the kilometers are with how much you need to spend on gas

[1] 128 litres.

[2] $115.2.

Step-by-step explanation:

(1) In 12.5km, car takes 1 litre.

In 1km, car takes 1/12.5

For 1,600km, 1/12.5 × 1600

= 128 litre of gas.

(2) For 1 liter, he pays $0.90

So, for 128 litres of gas, he pays:

= 128 × 0.90

= 115.2$.

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
