check the picture below.
so, we know the dimensions of the pool, is a 20x10, so its area is simply 200 ft², and we know the walkway is 216 ft², so the whole thing, including pool and walkway is really 200 + 216 ft².
now, as you see in the picture, the dimensions for the combined area is 20+2x and 10+2x, since the walkway is "x" long, therefore,
notice, it cannot be -18, since is a positive length unit.
Answer:
$223.
Step-by-step explanation:
Let x be the original price of phone.
We are told that Terry sees this offer refurbished phone 35% off now only $78.
We need to find x such that 35% of x is 78. We can represent this information as:
Therefore, the original price of phone was $223.
Answer:
97/40
Step-by-step explanation:
so 2.125= 17/8
3/10+17/8 need to find common denominator so
times 8/8 to 3/10
times 10/10 to 17/8
24/80+170/80= 194/80 (common denominator so can add)
divide 194/80 because want reduce form
97/40 is the answer
(When i look at it now i can just time 4/4 and 5/5 but its ok this still gets the answer)
The answer is 18 equal line segments are needed to make 6 triangles.
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
