Answer:
C
Step-by-step explanation:
First, to make things simpler, let's create a common denominator for every term. We can do this by multiplying (x+4) and (x+3) when the denominator has a (x+3) or (x+4), respectively. In other words:
Now that they all have a common denominator, we can combine them:
Now, divide them. Recall how to divide fractions. You "flip" the second term and change the division sign into a multiplication sign.
Notice the denominator of the first term and the numerator of the second; we can cancel them out.
Now, we just need to simplify.
Answer:
12.2 ft
Step-by-step explanation:
Let length of pole be l.
In triangle ACD.
cos75 =x/l ...............................1
In triangle ABD
tan45 =1 = lsin(75)/(15-x) ..........................2
Now solve this linear equations
l(sin75 + cos75) =15
Square on both side
length of pole =12.2 ft
Answer:
6x - 4 = 32. The variable (times a number) is equal to 6.
Step-by-step explanation:
So this equation is basically asking you to formulate an equation using only the words given. For this equation, let's use a variable in place of the part where it says "times a number." When a question says that phrase, that means that they are telling you to use a variable in place of a mystery number. A variable is a letter in place of a mystery number. Knowing this, let's now solve the equation. We will use the variable x in place of our mystery number.
Four less than 6 times a number: 6x - 4 _ __.
Now we can add the equal sign and the 32: 6x - 4 = 32.
We can now solve. Add 4 to both sides of the equation to cancel out the -4:
6x - 4 = 32
<u>+4 + 4</u>
6x = 36
Now we divide 6 into both sides of the equation to single out the x.
<u>6x = 36</u>
6 6
36/6 = 6, so:
x = 6
