Answer:
<h2>x = 33 m</h2>
Step-by-step explanation:
Use the Pythagorean theorem:
We have
Substitute:
<em>subtract 3136 from both sides</em>
Answer:
11/12
Step-by-step explanation:
Multiply 1/4 times 3/3 and 2/3 times 4/4. That gives you 3/12 + 8/12. Add that together and you get 11/12
Answer:
x = 3.8
Step-by-step explanation:
Perimeter is all the side lengths added up.
Step 1: Set up equation
x + 2(8.3) + 3.8 = 24.2
Step 2: Solve for <em>x</em>
- Multiply: x + 16.6 + 3.8 = 24.2
- Combine like terms: x + 20.4 = 24.2
- Subtract 20.4 on both sides: x = 3.8
Since both equations equal y they need to equal each other.
2x - 5 = -3x + 10
Add 3x to both sides:
5x -5 = 10
Add 5 to both sides
5x = 15
Divide both sides by 5
X = 3
Now solve for y by replacing x with 3:
Y = 2(3)-5 = 6-5 = 1
Y = -3(3)+ 10 = -9+ 10 = 1
Check: replace y with 1 and solve for x:
1 = 2x -5
Add 5 to both sides
6 = 2x
Divide both sides by 2
X = 3 ( True)
Using distance formula, it is 13 units
