I am pretty sure the height is 4, but sorry if i am wrong
X+Y=42
X-Y=4
Add both equations.
X+X+Y-Y=42+4
2X=46
X=23
23-Y=4
Y=23-4=19
23 and 19
Answer:
A & B
Step-by-step explanation:
5x - 2y = 10 (1)
-2.5x + y = -5 (2)
When you multiply (2) by -2, you get (1), so there can be many solutions
To choose from the given options, plug in the values to check which ones satisfy the equation
5x - 2y = 10
A) (2,0)
5(2) - 2(0) = 10
10 = 10 (true statement)
B) (-2,-10)
5(-2) - 2(-10) = 10
-10 + 20 = 10
10 = 10 (true statement)
Answer:
A 180-pound kangaroo's recommended height is 6 feet.
Step-by-step explanation:
Since 120-pound kangaroo is 5 feet tall and for every inch over this height we add 5 pounds to the total weight, we can make this formula. . Using this we can figure out the weight difference between a 120-pound kangaroo and a 180-pound kangaroo. After solving for x we get .
Now that we know the 180-pound kangaroo weighs 60 more pounds than a 120-pound kangaroo we can divide that weight difference by 5 to figure out the height difference.
After getting the height difference from the weight difference we can conclude that a 180-pound kangaroo's recommended height is 5 feet and 12 inches. Since 12 inches = 1 foot we can easily convert 5' 12" to 6'. This means that a 180-pound kangaroo is 6 feet tall.
