That is 99 degrees if you have the triangle facing the other way
Answer:
The correct option is option B. It has one solution, and it's x=-3
Step-by-step explanation:
We have the following system of equations:
5x+7 = 2y (1)
y-9x=23 (2)
Step 1: Solve for 'y' in equation (2):
y-9x = 23
y = 9x + 23
Step 2: Substitute in equation (1):
5x + 7 = 2y
5x + 7 = 2(9x + 23)
5x + 7 = 18x + 46
Step 3: Solve for x:
7 - 46 = 18x - 5x
-39 = 13x
x= -3
So the correct option is option B. It has one solution, and it's x=-3
Answer:
-0.25 or 1/4
Step-by-step explanation:
Eh just know
2-10 = -8 I'm not sure what the 5,6,7,8,9,10 means if you tell me i might be able to help you
Equation Form:
w x 2
19
Divide both sides by 2:
w
9.5
So, w must be equal to or greater than 9.5 for this equation to work.
