Answer:
The answer is 18x.
Step-by-step explanation:
2x times 9 is 18x because when you multiply 9 times 2, you get 18 and the x carries over.
Answer:x=-1
Step-by-step explanation:
To solve 6-3+4x+1=
Collect like terms
6+1-3+4x=
7-3+4x=
4=-4x
x=-1
There is one solution
Since the ratio is 2:5, it could be written as a fraction: 2/5. To make this apply to the sides of the triangles you'd have to create an equation where 2/5 equals 5/x, x being the length of the hypotenuse.
2/5 = 5/x
To get from 2 to 5, you'd have to multiply 2 by 2.5. Therefore, in order to make the equation equal, you have to multiply 5 (the denominator of 2/5) by 2.5.
2/5 = 5/12.5
The hypotenuse would be 12.5 inches long.
Answer:
6, 12, 24, 48 and 96.
Step-by-step explanation:
We look for a geometric sequence with first term = 3:
nth term= a1 r^(n-1)
3 r^(n-1) = 192
r^(n-1) = 192 / 3 = 64
2 ^ 6 = 64 so r = 2.
Series is 3 ,6, 12, 24, 48, 96, 192.
So 5 geometric means would be 6, 12, 24, 48 and 96.
Answer:
No because they have different slopes
Step-by-step explanation:
(1 , 2) and (2, 4)
Slope:
m=(y2-y1)/(x2-x1)
m=(4-2)/(2-1)
m = 2
