Step-by-step explanation:
4/3 + 11/12
3 = 12 = 12
12 ÷ 3 = 4
12 ÷ 12 = 1
4 × 4 = 16
1 × 11 = 11
16 + 11 = 27/12
2/35 because there is still only 35 tickets and he/she buys 2. That means no matter what they have the 2 tickets. That gives them a 2 in 35 chance to win.
We can start this equation off by doing the inverse operation for each sides. We add 9 to both sides in order to get rid of the -9 term to get:
We now divide both sides by -11 in order to "isolate" our x variable to get:
Answer:
Option B.
Step-by-step explanation:
we know that
The area of a circle is equal to
we have
substitute
Remember that
radians subtends the complete circle of area
so
by proportion
Find the area of the related sector for a central angle of radians
Let
x------> the area of the related sector
The answer is A. x=4.
Start off by distributing the parentheses into the equation.
4x+2(x+6)=36
4x+2x+12=26
Combine like terms.
4x+2x=6x
6x+12=36
Now solve the equation as normal. Begin by subtracting 12 from both sides to isolate the variable.
6x+12=36
-12 -12
---------------
6x = 24
Divide 6 on both sides to find x.
6x=24
---- -----
6 6
x=4
The solution to the equation is 4.
