Answer:
-5x=-23
Or
X=23/5
Step-by-step explanation:
Answer:
<em>x = 7</em>
Step-by-step explanation:
Simplifying
17 = 3X + -4
Reorder the terms:
17 = -4 + 3X
Solving
17 = -4 + 3X
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-3X' to each side of the equation.
17 + -3X = -4 + 3X + -3X
Combine like terms: 3X + -3X = 0
17 + -3X = -4 + 0
17 + -3X = -4
Add '-17' to each side of the equation.
17 + -17 + -3X = -4 + -17
Combine like terms: 17 + -17 = 0
0 + -3X = -4 + -17
-3X = -4 + -17
Combine like terms: -4 + -17 = -21
-3X = -21
Divide each side by '-3'.
X = 7
Simplifying
X = 7
Which statements are true about the ordered pair <span>(−1, 5)</span> and the system of equations?
<span>{<span><span>x+y=4 </span><span>x−y=−6</span></span></span>
Select each correct answer.
<span>The ordered pair <span>(−1, 5)</span> is a solution to the first equation because it makes the first equation true.The ordered pair <span>(−1, 5)</span> is a solution to the second equation because it makes the second equation true.The ordered pair <span>(−1, 5)</span> is not a solution to the system because it makes at least one of the equations false.The ordered pair <span>(−1, 5)</span> is a solution to the system because it makes both </span>
Answer:
<u>h = V/r²</u>
Step-by-step explanation:
The formula is :
- V = r²h (actually 1/3πr²h in real life)
Solving :
- Dividing both sides by r²
- V/r² = r²h/r²
- <u>h = V/r²</u>
A^2 + b^2 = c^2
8^2 + b^2 = 11^2
64 + b^2 = 121
b^2 = 121 - 64
b^2 = 57
b = sqrt 57
b = 7.54 rounds to 7.5 ft <==
