Answer: Yes the mixed 3 1/4 is a rational number.
Step-by-step explanation:
Answer:
x=70
y= 40
Step-by-step explanation:
the triangle containing x is an isosceles triangle so two of the sides are 55.
55+55+x=180.
110+x=180
110-110+x=180-110
x=70
Triangle BAC is equilateral so 180/3=60. Now
x+60+c=180
70+60+c=180
130+c=180
130-130+c=180-130
c=50
That gives us one corner of triangle CBD. We know a second angle is 90 so
50+90+y=180
140+y=180
140-140+y=180-140
y=40
I think that is correct but you are free to check it yourself
Answer:
Y IS EVERYTHING THAT IS LESS THAN -3X
Step-by-step explanation:
LOOK AT THE LESS THAN SIGN
Your equation is a little messed up comment me the equation you need help with
2x² - 15x + 7
(2x - 1)(2x-14)
(2x - 1)(x - 7) x= 1/2 or 7
