Answer:
39/50
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
0.78=0.781
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 102 = 100
0.781×100100=78100
Find the Greatest Common Factor (GCF) of 78 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,
78÷2100÷2=3950
Therefore
X=3950
In conclusion,
0.78=3950
Answer:
x=3, 8
Step-by-step explanation:
x²-11x+24=0 can be factored to
(x-3)(x-8)=0
3-3=0
8-8=0
So, x can be 3, 8
It’s 0 because it’s a horizontal line and doesn’t have any change.
Answer:
6x-18
Step-by-step explanation:
First we multiply everything in the parentheses by 3
3×2x=6x
3×(-6)=-18
And now we put it together-
6x-18
No, the 2 lines can never ever be both parallel and perpendicular if I'm not mistaken. This is because a set of parallel lines will never touch each other at all. However perpendicular lines are two lines that meet up to get an angle of 90. You cannot have two lines that never touch and touch at the same time.
