Answer:
<h2>y=60+25h+0.3r</h2>
Step-by-step explanation:
let y be the total charges
given that the hour is h
and the cost for raw material is r
therefore
1. The first hour of service call = $60
2. For each additional hour= 25h
3. 30% over the cost of the materials.= 30/100*r=0.3r
total charges
y=60+25h+0.3r
therefore the expression is
y=60+25h+0.3r
Answer:
28 km
Step-by-step explanation:
One leg = 35 km
Second leg = 21 km
We need to find the length of the missing leg. Using Pythagoras theorem, we can find it.
Hypotenuse² = base² + perpendicular²

So, the length of the missing leg is equal to 28 km.
Answer:
s=$35n
Step-by-step explanation:
have fun w/ this (also can I get brainiest?)
<span>A quarter is equivalent to 25 cents or $0.25 and a nickel is equal to 5 cents or $0.05. In the given in this item, if there are x nickels then, there are x + 7 quarters. With these and the total amount known, we can now compute for the value of x.
(x)(0.05) + (x + 7)(0.25) = 2.65
Simplifying,
0.05x + 0.25x + 1.75 = 2.65
Simplifying further,
0.3x = 0.9
The value of x from the equation is 3. Hence, there are 10 quarters.</span>
First you separate them, the x’s in one side and whole numbers on the other then simplify
