It would be 7 because he gets in an accident every other time he gets a ticket

First work out the slope of the line
slope = rise / run   if you look at the pointt level with accidents  is  you see that rise / run - = 3.5 / 7  which is 0.5
The intercept on vertical axis is 1.5 
so we can write the equation of the line ( y = mx + b) where m = slope and b = y intercept) as  y = 0.5x + 1.5   ( y = accidents and x = number tickets)

so if we plug x = 10 (tickets) into the above 

Accidents ( for 10 tickets) = 0.5(10) + 1.5 = 6.5 which we round up to 7.

A motorboat travels 165 kilometers in 3 hours going upstream and 510 kilometers in 6 hours going downstream. What is the rate of
nikitadnepr [17]
<h3>Rate of the boat in still water is 70 km/hr and rate of the current is 15 km/hr</h3><h3><u>Solution:</u></h3>

Given that,

A motorboat travels 165 kilometers in 3 hours going upstream and 510 kilometers in 6 hours going downstream

Therefore,

Upstream distance = 165 km

Upstream time = 3 hours

<h3><u>Find upstream speed:</u></h3>

speed = \frac{distance}{time}\\\\speed = \frac{165}{3}\\\\speed = 55

Thus upstream speed is 55 km per hour

Downstream distance = 510 km

Downstream time = 6 hours

<h3><u>Find downstream speed:</u></h3>

speed = \frac{510}{6}\\\\speed = 85

Thus downstream speed is 85 km per hour

<em><u>If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then</u></em>

Speed downstream = u + v km/hr

Speed upstream = u - v km/hr

Therefore,

u + v = 85 ----- eqn 1

u - v = 55 ----- eqn 2

Solve both

Add them

u + v + u - v = 85 + 55

2u = 140

u = 70

<em><u>Substitute u = 70 in eqn 1</u></em>

70 + v = 85

v = 85 - 70

v = 15

Thus rate of the boat in still water is 70 km/hr and rate of the current is 15 km/hr

How to divide 6,875 by .025
Leokris [45]
Answer= 285000
How to= the number you are dividing by has a decimal move the decimal point all the way to the right counting the number of places you’ve moved it to. Then move the decimal point in the number you’re dividing the same number of places to the right

A system of equations is shown below:
JulijaS [17]
X+y=3

Subtract x from both sides

y=-x+3

Substitute

2x--x+3=6
2x+x+3=6
3x+3=6

Subtract 3 from both sides

3x=3

Divide both sides by 3

x=1

I need to know number six and thank you guys for all the help
Zigmanuir [339]

Answer:

D

Step-by-step explanation:

First of all, a very easy way is to count all the rectangles and then count the squares that are shaded and have balloons.

You'll get 7 squares that are shaded and have balloons and 16 rectangles in total.

So the fraction will be \frac{7}{16}

Another simple way is to just multiply \frac{7}{8} and \frac{1}{2}

\frac{7}{8}*\frac{1}{2}=\frac{7}{16}
