1 answer:

5 0

First, you have to multiple 4 to (.34x+1.4) and you will get (1.36x+5.6). Then you subtract 1.36x to the right side and you will get (-0.36x=5.6). Finally, divide both sides by -0.36 and you will end up with -140/9 as your answer.

A car's speedometer has a percent error of 5%. The speedometer currently shows that the car is traveling at a speed of 60 mph.

Minchanka [31]

Answer:

The actual speed of the car is either 57 mph or 63 mph

Step-by-step explanation:

Given as :

The measured speed o the car = 60 mph

The percentage error in speedometer = 5 %

Let The actual speed of car = x mph

Now, percentage error = $\dfrac{\textrm actual value - \textrm measured value}{\textrm measured value}$ × 100

So, $\frac{5}{100}$ = $\frac{x - 60}{60}$

or, $\frac{5}{100}$ × 60 = x - 60

Or, 3 = x - 60

∴ x = 63 mph

Hence The actual speed of the car is either 57 mph or 63 mph . Answer
