Answer: x = -100. For you Id say the second one
Step-by-step explanation: multiply both sides, multiply reduce, and multiply.
12 in is 1 ft so 35/12 is 2.91 rounded is 3 ft.
Answer:
t is between 0 seconds and 4.878
Step-by-step explanation:
Given:
Inequality:
Required
Determine the value(s) of t
To answer this question, we simply solve the inequality
Subtract 10 from both sides
Multiply through by -1
Solve the value of t using quadratic formula
Where
<em>a = 4.9; b = -22 and c = -9.25</em>
So:
Split the expression
or
or
or
Since t cannot be negative; Then
<em>Hence; t is between 0 seconds and 4.878</em>
Answer:
Step-by-step explanation:
Step 1:
Isolate x (1st Equation)
2x + 3y = 0
<u> - 3y = -3y</u>
2x = -3y
Step 2:
Divide both sides by 2
x = -3y/2
Step 3:
Replace the x from 8x with -3y/2 and Solve the equation
8(-3y/2) + 9y = 18
-12y + 9y = 18
-3y = 18
y = -6
Step 4:
Go back to the 1st equation and replace the y from 3y with -6. You are now solving for x. Solve the equation.
2x + 3(-6) = 0
2x - 18 = 0
<u> + 18 = +18</u>
2x = 18
x = 9
Step 5:
Write your final answer.
(x, y) = (9, -6)
Answer:
Step-by-step explanation:
<u><em>Length</em></u>
1 inch = 25 feet
7 1/4 inches = x feet
1 * x = 25 * 7 1/4
x = 25 * 7.25
Length = 181.25 feet
The length is 181.25
<em><u>hypotenuse length</u></em>
The diagonal = 10 1/2 inches
The diagonal = 10.5 inches
hypotenuse = 10.5 * 25 = 262.5 feet
<em><u>Width</u></em>
L^2 + W^2 = Diagonal^2
181.25² + W² = 262.5²
32851.5625 + W² = 68906.25 Subtract 32851.5625 from both sides
W² = 68906.25 - 32851.5625
W^2 = 36054.6875 Take the square root of both sides
W = 189.88
<u><em>Area</em></u>
Area = L * W
Area = 181.25 * 189.88
Area = 34415.88 square feet.
