<span>The cost that a carpet cleaning company charges is directly proportional to the number of rooms cleaned. The cost is $22 for each room.</span>
I’m the first equation solve for y
5x-y=-5
Subtract 5x from both sides
-y = -5-5x
Multiply both sides by -1
Y = 5+5x
Now plug this in for y in the other equation
3x-6(5+5x) =24
Distribute
3x-30-30x=24
Simplify
-27x-30 = 24
Add 30
-27x = 54
Divide
X = -2
Now plug this in the first equation
Y = 5+5(-2)
Y = 5 -10
Y = -5
So X = -2, Y = -5
About 2.2222
rounded answer: 2.23
Answer:
The answer is
<h2>144 square inches</h2>
Step-by-step explanation:
Area of a triangle is given by
<h3>
</h3>
where
b is the base
h is the height
From the question
b = 16 inches
h = 18 inches
Substitute the values into the above formula and solve for the area
That's
<h3>
</h3>
We have the final answer as
<h3>144 square inches</h3>
