9 because when you subtract the amount of poster money from the total ($19.35), you get $14.85. $14.85 divided by $1.65 is 9, which means he bought 9 notebooks.
- The distance travelled by both Evelyn and Ricky is 45 miles
If Speed = dist/time, then;
<u>dist = speed * time</u>
<u />
We also know that both of them travel the same distance, so we equate the distance travelled to each other
36 * x+45 = 72 * x
36x + 1620 = 72x
72x - 36x = 1620
36x = 1620
x = 1620/36
<u>x = 45 miles</u>

Answer:
5^2+12^2= c^2
25+144=c^2
169=c^2
find the square root of 169
the length is = 13 ft
Step-by-step explanation:
Answer:
y=3/5x-1
Step-by-step explanation:
The formula you need to find this would be
(y-y1)=m(x-x1)
The y1 is your y point.
The x1 is your x point.
m is your slope.
Start by plugging in your numbers that they provide you.
(y-8)=3/5(x-15)
Now you need to distribute the slope to the terms inside the parenthesis next to it.
3/5(x)=3/5x
3/5(-15)= -9 Now you put those back into the equation.
(y-8)=3/5x-9
At this point you can get rid of the parenthesis around the y-8 since it is basically saying to take the term times 1.
To get y alone we not need to add 8 to both sides.
y-8=3/5x-9
+8 +8
y=3/5x-1
-1.5. -1 1/2. -3/2
yeah so its this i’m 99.98% sure
