Answer:
x = -4; y = 3
Step-by-step explanation:
-3x + 4y = 24
6x + 2y = -18
Rewrite the first equation as it is. Divide both sides of the second equation by 2 and write it below the first equation. Then add the equations.
-3x + 4y = 24
+ 3x + y = -9
----------------------------
5y = 15
Divide both sides by 5.
y = 3
Now plug in 3 into y in the first original equation and solve for x.
-3x + 4y = 24
-3x + 4(3) = 24
-3x + 12 = 24
-3x = 12
x = 12/(-3)
x = -4
Answer: x = -4; y = 3
I’m preety sure it’s gonna be the second one correct me if I’m wrong
Option (A)
Given:
Height of Molly is 5 3/4 feet takk.
Height of Andy is 6 1/6 feet takk.
The objective is to find how much taller is Andy than Molly.
The given equation can be wtitten as,
THe difference between their height can be calculated as,
Hence, option (A) is the correct answer.
Answer:
y = + 6
Step-by-step explanation:
3:8 is the original ratio
multiple both sides by 3 to make it 3 times greater
the answer would be 9:24
hope this helps!!
