First add 2 to both sides, next add 2 + 3 to get 5, next break down the equation into two problems which would be 2x - 5 = 5 and -(2x - 5) = 5, NOT 2x - 5 = -5, so this is the FIRST incorrect step, while step 4 is incorrect because its suppose to be 2x = 5 not 10, that's the second step, not first so answer is:
Answer: A) Step 3.
2 Answer:
16
Step-by-step explanation:
Ok this isn’t my answer i found it on quora but it answers ur question u have
We can write a system to solve this problem
Let x= the radius of Circle A
Let y=the diameter of Circle B
x=2y-3
2x+y=49
since we are trying to find the area and the circumference of circle A, we only have to find what x is
x=2y-3 → y=1/2x+3/2
next, we plug in 1/2x+3/2 for y:
2x+1/2x+3/2=49
we can then multiply all the numbers by 2 to get rid of the fractions:
4x+x+3=98
5x+3=98
5x=95
x=19
Circle A radius=19ft
Finally, we solve for the area and circumference:
Area:
A=pi*r^2
A=3.14*19^2
A=1133.54 feet^2
Circumference:
C=2*pi*r
C=2*3.14*19
C=119.32 feet
Answer:
22 meters
Step-by-step explanation:
What we know:
Side AB is 7 1/2 m long, Side BC is 2 1/4 m long, and Side DE is 1 1/4 m long.
Saying Sides AH and FG are the same as Sides DE and BC respectively, we can add another 3 1/2 m to the perimeter.
If CD, EF and GH are each 1/3 of AB, then 7 1/2 is added again.
7.5 + (2.5 * 3) * (2.25 * 2) + (1.25 * 2)
7.5 + 7.5 + 4.5 + 2.5
15 + 7
The perimeter is 22 meters.
In the standard form its same but in slope form (-5,1)(0,6) -1
