Answer:
x= 1
y= 3
Step-by-step explanation:
21(-2+y) +7y = 42
-42 +28y+42
28y = 42+42
28y= 84
divide both sides y= 3
x= -2+3 x=1
x= + (3-2) = 1
42=42
10=10
-7/9 - 4/9 =?
-10/9 simplified to -1 1/9
$25
$5 is one fifth, so 5x5 is 25
Answer:
Step-by-step explanation:
Let’s say the third length is x. We can use the Pythagorean Theorem which states that a^2 + b^2 = c^2 where a and b are the legs and c the hypotenuse. Using Pythagorean Theorem, we can see that x^2 + 6^2 = 9^2. Solving we get that x^2 = 45 -> x =
