Set is a sum of two intervals :(1,4) u [2,6]
In the first interval it is open on both sides so 1 and 4 don't belong to this interval, the second is closed so both 2 and 6 belong to interval and numbers between 2 and 6
We can write it as 1<x
summing both sets we have one set: (1,6]
so
a) represent our set
b) also represent because all numbers between 4-6 and 6 are in our set
c)also represent, all numbers are in main set
d)also represent
Both angles equal 73, according to the vertical angle conjecture. To solve for x:
(1+2x)=73
2x=72
x= 36
]Answer:
Step-by-step explanation:
Substitute the value of the variable into the equation and simplify.
Solve it out.
Multiply / divide / add / subtract everything out.
The correct answer is:
[B]: "
9.6 cm " .
____________________________________________________________Explanation:____________________________________________________________Let "FH" = "x" ; for which we wish to solve.
45 cm / 12 cm = 36 cm / "x" (in "cm") ;
To solve for "x" ;
Cross--multiply:
Note: Given:
"
" ; "
ad = bc " ; (b ≠ 0 ; d ≠ 0) ;
So: " 45x = 12 * 36 " ;
→ 45x = 432 ;
Divide each side of the equation by "45" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
→ 45x / 45 = 432 / 45 ;
→
x = 9.6 cm ;
