Answer: 21

Step-by-step explanation: To solve this problem, we can first set up a proportion because we know that 3 is to 7 as 9 is to x.

So we have \frac{3}{7} = \frac{9}{x}.

Now, we can use cross products to find the missing value.

So we have 3 time x which is 3x and 7 times 9 which is 63.

Rewriting our equation, we have 3x = 63.

Dividing both sides by 3, we find that <em>x = 21</em>.

So, <em>x = 21</em>.

The red arrows in the middle mean that they are parallel so the slopes are the same.

laurens suv was detected exceeding the posted speed limit of 60 kilometers per hour , how many kilometers would she have been tr
Vlada [557]

Answer:

60 kilometers per hour (kmph) over the limit

Step-by-step explanation:

The speed limit is 60 kmph

Let's find his original rate:

We know D = RT

Where

D is the distance, in km

R is the rate, in kmph

T is the time in hours

He went 10 km in 5 minutes, so we need the time in hours, first. That would be:

5/60 = 1/12 hour

So, putting into formula, we find rate:

D = RT

10 = R(1/12)

R = 10/(1/12)

R = 10 * 12

R = 120 kmph

He was going over by:

120 - 60 = 60 kmph
