see the attached figure to better understand the problem
Step 
in the triangle ABC
<u>Find the distance AC</u>
we know that
In the right triangle ABC
solve for AC
substitute the values
Step 
in the triangle DEF
<u>Find the distance DF</u>
we know that
In the right triangle DEF
solve for DF
substitute the values
Step 
Find the value of x
we know that
the value of x is the difference between AC and DF
round to the nearest meter-------> 
therefore
<u>the answer is</u>
The value of x is

1.3*3=3.90
3.90*35=136.50
136.50 is all you need to provide at least three of the most expensive items.
You still have 13.50 left over
Answer:
7
Step-by-step explanation:
If u add all 5 puppies ages together including the 7 week old one it will equal 45 divide that by 5 and you get an average of 9 weeks.
<h3>Answer: 8x+3y = 16</h3>
============================
Work Shown:
x = number of hours spent running
8x = distance he runs (since he runs at 8 mph)
y = number of hours spent walking
3y = distance he walks (he walks at a speed of 3 mph)
8x+3y = total distance = 16 miles
8x+3y = 16
This equation is in standard form Ax+By = C
--------
Extra Info
Solving for y will get
8x+3y = 16
3y = -8x+16
y = (-8x+16)/3
y = (-8x)/3+16/3
y = (-8/3)x+16/3
This is in slope intercept form y = mx+b
m = -8/3 is the slope
b = 16/3 is the y intercept
