Answer:
He can buy 3 plants
Step-by-step explanation:
$27 is the total amount of money he can spend, if each plant costs $9 the equation would be like this:
9x = 27
Divide 27 by 9 because division is the opposite operation to multiplication
x = 3
The answer to your question is 2 hope this helps!
For this problem I would change:
2x + 3y = 25 into
-2x - 3y = -25
Then, I would add up both equations by lining them up top of another.
5x + 3y = 31
+ -2x - 3y = -25
3x = 6
x = 2
Now that you have x, solve for y.
5x + 3y = 31
5(2) + 3y = 31
10 + 3y = 31
3y = 21
y = 7
So, x is 2 and y is 7.
Check to see if the values are correct by plugging them into the other equation.
2x + 3y = 25
2(2) + 3(7) = 25
4 + 21 = 25
25 = 25
Since the values are correct, the solution to this problem is A (2, 7).
A. 5+2m
B. $305.
This is because 150*2=300, plus an initial fee of five dollars. 300+5 is 305.
