Let x be the cost of one rose bush and y be the cost of one carnation.
Then we have the system of equations:
x * 9 + y * 12 = 210
x * 3 + y * 1 = 40
To determine the method that is most efficient to solve this system, we can use the fact that one of the equations has already solved for one of the variables, y.
We can use substitution to solve for the other variable, x.
Substitute y = (40 - 3x) into the first equation:
x * 9 + (40 - 3x) * 12 = 210
Simplify:
x * 9 + 480 - 36x = 210
Solve for x:
9x - 36x = 210 - 480
-27x = -270
x = 10
Substitute x = 10 into the second equation:
10 * 3 + y = 40
Solve for y:
y = 10
Therefore, one rose bush costs $10 and one carnation costs $10.
The most efficient method to solve the system was substitution, since one of the equations already solved for one of the variables.

Can someone please help me with this question?
Answer:
110 degrees
Step-by-step explanation:
Ok so no matter what the shape is, the exterior angles always have to add up to 360 degrees. Then, you can make the equation:
140 + 110 + x = 360
250 + x = 360
x = 110 degrees
Here's another way you can do it:
To do this, you can start by noticing that the top angle would be 40 degrees, because there's a straight line with 140 degrees and that angle, so you can do 180 - 140 = 40 degrees.
Then, the angle towards the bottom right would be 70 degrees using the same strategy:
180 - 110 = 70 degrees
The interior angles of a triangle always have to add up to 180 degrees, so you can do 180 - 40 - 70 = 70 to find the third interior angle of the triangle.
The last step is to do 180 - 70 = 110 to find the measure of the exterior angle at that point.

Solve for angle b and c
Answer:
46 degrees for both b and c
Step-by-step explanation:
the vertical angles postulate means that the opposite angle must be the same, so 134*2=268
since all angles must be 360, subtract 268, which is 92
using the vertical angles again, b and c are the same, and the sum must be 92
92 divided by 2 is 46

3n+5-12n-8+6p
Answer
-9n-3+6p
Step-by-step explanation:
Answer:
-9n - 3 + 6p
Step-by-step explanation:
You have to remember that you can add or subtract only LIKE terms. In other words, you can't add 3n + 5, so separate them.
In this equation: 3n + 5 - 12n - 8 + 6p,
1. 3n - 12n
2. 5 - 8
3. 6p
= -9n - 3 + 6p

Combine like terms
7k + 4(k + 4)
A.8k + 16
B.11k + 16
C.7k + 1k + 16
D.27k
Answer:
B. 11k + 16
Step-by-step explanation:
We have an expression and are asked to combine like terms.
To solve this, we need to first distribute 4(k + 4). Which is to multiply four by both k and 4.
(4(k) + 4(4))
4k + 16
7k + 4k + 16.
Since 7k and 4k are like terms since they end in the same variable, we can only add them.
7 + 4
11
11k + 16
