Answer:
Step-by-step explanation:
hello :
y= 5x + 9
y = -x +3
so : 5x+9 = -x+3
5x+x= 3-9
6x=-6
x=-6/6 = -1
I had that question yesterday
Answer:
x=23.5
Step-by-step explanation:
90=25-x/2+18
combine like terms
90=43-x/2
subtract 43 from both sides
47= -×/2
47/2= 23.5
x=23.5
or
90-25= 65
65-18=47
47/2=23.5
Answer:
1) 120
2) 30
3) 30
Step-by-step explanation:
Angle 1 is the same as the angle shown at 120
Use that to find 2, which is also 3
so 180-120 = 60
divide by 2
2 and 3 are both 30 each
PQR is most likely a triangle
