Answer:
<h2>20.14</h2>
Step-by-step explanation:
according to the trig ratio , we will use cos
that is , tan 40 = x/24
0.8391 =x/24
x = 0.8391 times 24
x =20.1384 to whole number is 20
Hope this is helpful :-)
Answer:
x = 8
Step-by-step explanation:
6 = 14 - x
chance the equation around so it is solvable
14 - x = 6
14 - 6 = x
now solve
14 - 6 = 8
that means x equals 8 so
6 = 14 - 8
This question is the usual way to do this problem. Just multiply the 4 by 2 so that you have 3*? / 4 * 2 .
What you do to the top part of the fraction is what you do to the bottom part.
3*2 / 4 * 2 = 6 / 8
So the answer is 6 / 8
Answer:
x = 5
Step-by-step explanation:
Simplify. First, combine like terms:
3x - x + 2 = 12
(3x - x) + 2 = 12
(2x) + 2 = 12
2x + 2 = 12
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
& is your order of operation.
First, subtract 2 from both sides:
2x + 2 (-2) = 12 (-2)
2x = 12 - 2
2x = 10
Next, divide 2 from both sides:
(2x)/2 = (10)/2
x = 10/2
x = 5
5 is your answer for x.
Check: Plug in 5 for x in the equation. Solve:
3(5) - (5) + 2 = 12
15 - 5 + 2 = 12
10 + 2 = 12
12 = 12 (True)
