Answer:
Fast car = 45.6
Slower car = 30.4
Step-by-step explanation:
Let the speed of the first car = x
Let the speed of the second car = y
Travelling towards each other.
x *1 + y*1 = 76 miles
x*5 - y*5 = 76 miles. This is kind of tricky. You have to understand that the first car that is 76 miles from the second car and makes up that 76 in 5 hours. The distance they both travel is subtracted out.
Divide by 5
x - y = 76/5
x - y = 15.2 The speeds differ by 15.2
x + y = 76
x - y = 15.2
2x = 91.2
x = 45.6
y = 76 - 45.6 = 30.4
When the two vehicles speeds are multiplied by 5, the difference is 76 km
Answer:
Step-by-step explanation:
The rate for power lines on poles, the one that Dexter uses, is $41.16 then the equation for what he owes that depend on the number of watts he uses is:
Y(what he owes)= $41,16*x(number of watts)
Y= $41,16x
If Dexter do not use the power lines underground, then we should not include this on the equation for what he owes.

The length of the hypotenuse is 40 mm.
<u>Step-by-step explanation:</u>
<em>We can solve for 'c' using Pythagoras theorem. Let's solve it.</em>
-
c² = 32² + 24²
- => c² = 1024 + 576
- => c² = 1600
- => c = 40
Hence, the length of the hypotenuse is 40 mm.
Hoped this helped.
Answer:
2/3x
Step-by-step explanation:
Your subtracting 4-2=2 the denominator stay the same
Would it be 2.95? It would be 2.95 If you are trying to get the profit back to 2.5, since you would add all the numbers together (subtract the negatives) and the answer would be .45 which you'd add to 2.5 to equal 2.95
