Answer: A is the right angle
Step-by-step explanation:
a. 20^2 + 15^2 = 25^2
400 + 225 = 625
625 = 625

This question is given you the information of the two units mileage in terms of miles per gallon and fuel consumption. G is gallons. Therefore meaning, total distance is equal (=) to mileage times (X) fuel consumption.
The answer is: A) m = f(g) = 30 × g
Answer:
27 and 23
Step-by-step explanation:
x + y = 50
x - y = 4
2x = 54
x = 27
y = 23
Answer:
Your solution is (9, 27) or x = 9, y = 27
Step-by-step explanation:
y = 2x + 9
y = 4x - 9
We can see that both of these equations equal y, so we can set them equal to each other.
2x + 9 = 4x - 9
Add 9 to both sides.
2x + 18 = 4x
Subtract 2x from both sides.
18 = 2x
Divide both sides by 2.
9 = x
Now we want to find y. To do this, plug x = 9 back into one of the original equations.
y = 2(9) + 9
Multiply.
y = 18 + 9
Add.
y = 27
Your solution is (9, 27)
Check your answer by plugging x = 9 and y = 27 back into the original equations.
y = 2x + 9
27 = 2(9) + 9
27 = 18 + 9
27 = 27
y = 4x - 9
27 = 4(9) - 9
27 = 36 - 9
27 = 27
Your answer is correct.
Hope this helps!
U divide 330 by 15 and get the quotient then do the same thing to 20 and add the quotients together to solve for x and y
