A taxi journey of 30km cost $3,600.At the same rate per kilometer .A what would be the cost of travelling 25k.B.How far could yo

madreJ [45]

Answer:

The cost of traveling 25km would be $3000.

You can travel 35 km for $4200.

Step-by-step explanation:

Consider the provided information.

For 30km cost $3,600.

30 km = $3600

Divide both sides by 30.

$\frac{30}{30}\text{ km}=\frac{3600}{30}$

$1 \text{ km} =120$ ....(1)

The cost of 1 km is $120.

Part (A) what would be the cost of traveling 25km

Multiply both the sides of equation 1 by 25.

25 km = 3000

Hence, the cost of traveling 25km would be $3000.

Part(B) How far could you travel for $4,200?

Divide 4200 by 120.

$\frac{4200}{120}=35$

Hence, you can travel 35 km for $4200.

According to the graph what is the value of the constant in the equation below

murzikaleks [220]

The width is the x-value, meaning that the constant has to be divided by the x-value to get the y-value (height), so take (5,20) for example.

The equation would be 20=(x/5). Multiply both sides by 5 to get x by itself. This gives you that x=100. The constant is 100.

Therefore, the answer is C: 100.
