Answer:
22
Step-by-step explanation:
You add up the value of each X and you get a final answer of 22. Have a great day!
Step-by-step explanation:
we divide both sides by 4 to single out the X
(4X) / 4 = (2/3)/4
simplify
X = 2/12
Answer:
4x+5y-34=0
Step-by-step explanation:
The slope-intercept form of a line is y=mx+b where m is the slope and b is the y-intercept.
My goal is to put in in this form first. Then I will aim to put it in general form, ax+by+c=0.
So let's give it a go:
m is the change of y over the change of x.
To compute this I'm going to line my points up and subtract vertically, then put 2nd difference over 1st difference. Like this:
( 1 , 6)
-(6 , 2)
----------
-5 4
So the slope is 4/-5 or -4/5.
So m=-4/5.
Now we are going to find b given y=mx+b and m=-4/5 and we have a point (x,y)=(1,6) [didn't matter what point you chose here].
6=-4/5 (1)+b
6=-4/5 +b
Add 4/5 on both sides:
6+4/5=b
30/5+4/5=b
34/5=b
So the y-intercept is 34/5.
The equation in slope-intercept form is:
y=-4/5 x + 34/5.
In general form, it is sometimes the goal to make all of your coefficients integers so let's do that. To get rid of the fractions, I'm going to multiply both sides by 5. This clears the 5's that were on bottom since 5/5=1.
5y=-4x+34
Now add 4x on both sides:
4x+5y=34 This is standard form.
Subtract 34 on both sides:
4x+5y-34=0
If AP and BP are tangent segments connected outside of the circle at point "P" then <span>AP = BP so,
10x - 15 = 7x + 3</span>
3x = 18
x = 6
Answer:
17% off $35
Step-by-step explanation:
The reason I say 17% off $35 is better price is because you get $5.95 off the original price.
So how did you do it they wonder, well in order to find out how much we are going to be taking off of a number as a percentage we have to turn 17% and 12% into a decimal by multiplying 17% and 12% by 100.
17% * 100 = 0.17
12% * 100 = 0.12
Now we multiply 0.12 by $32 and 0.17 by $35 in order to find out how much money you are saving:
0.12 * $32 = $3.84
0.17 * $35 = $5.95
So since $5.59 is bigger than $3.84 you have your answer 17% off $35 is a better price.
