Answer:
Step-by-step explanation:
You need to set the problem up like this:
- subtract 3 from both sides. x=5
- because 'x' equals 5, plug that 4(5)=3(5)+5
back in for all the 'x's
- simplify the equation 20=20
- The length of the line segment
should be 20
Hey there!
10 * 8 = 8 * e
10 * 8 = 80
80 = 8 * e
8 * e = 80
8e = 80
DIVIDE 8 to BOTH SIDES
8e/8 = 80/8
CANCEL out: 8/8 because that gives you 1
KEEP: 80/8 because that gives the value of x
x = 80/8
80/8 = x
10 = x
x = 10
Therefore your answer is: 10
Because, 10 * 8 = 8 * 10
Good luck on your assignment and enjoy your day!

Answer:
Building A is 660 feet and Building B is 830 feet
Step-by-step explanation:
Let x represent the height of building B.
Since building A is 170 feet shorter than building B, it can be represented by x - 170.
Create an equation and solve for x:
(x) + (x - 170) = 1490
2x - 170 = 1490
2x = 1660
x = 830
So, the height of building B is 830 feet.
Subtract 170 from this to find the height of building A:
830 - 170
= 660
Building A is 660 feet and Building B is 830 feet
Answer:
x = 1
Step-by-step explanation:
the triangles are the same,
7 = 3x + 4
7 - 4 = 3x
3 = 3x
x = 1

Answer: 14.32 degrees
The circle has a diameter of 8 kilometers, so the perimeter would be:
perimeter= pi * diameter
perimeter= 22/7 * 8 kilometers= <span>25.14 kilometers
A full perimeter </span>of the circle, which is 25.14km, has 360° angle. So 1km arc would be: 1km/ 25.14 km * 360°= 14.32°
