Hope this helps :D
Answer:angle x=5
Step-by-step explanation:
Sum of triangles =180 ,x+90+45+40=180, x+175=180 ,x =5
So basically... you divide the 3 to 2 and that's how you get the decimal. The decimal is... 0.666666666667
Answer: Negative
Step-by-step explanation: Since the values of A and B are both negative (because they are below 0), adding them together will also make the sum negative.
Answer:
D
Step-by-step explanation:
out of the choices
A) 2x-y=-2
3x+2y=-10
B) x+4y=3
2x+5y=3
C) 2x+3y=5
x-4y=-14
D) 3x+4y=15
x+y=5
only the system in D has a solution of x=5 and y=0
solve by substitution x+y=5 so x=5-y
plug into the other equation so 3(5-y)+4y=15
distribute 15-3y+4y=15 then minus 15 on both sides and combine like terms
so y=0 then put that value back into the other equation
so x+y=5 equals x+0=5 so x=5 this means the solution to the system of equations is the point (5,0)
Hope this helps! :)
