What I would do is draw out a number line and draw a line above the fractions 5/8 and 3/8, to show the differences. I hope this helped. :)
Answer:
x = 25
Step-by-step explanation:
Correct question
In a right triangle Sin (40-x)=cos(3x) what is the value of x
Since Sin theta = Cos(90-theta)
Sin (40-x) = Sin(90-3x)
40 - x = 90 - 3x
-x+3x = 90 - 40
2x = 50
x = 25
Hence the value of x is 25
Answer:
Step-by-step explanation:
Simplifying
4x + 11 = k
Reorder the terms:
11 + 4x = k
Solving
11 + 4x = k
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-11' to each side of the equation.
11 + -11 + 4x = -11 + k
Combine like terms: 11 + -11 = 0
0 + 4x = -11 + k
4x = -11 + k
Divide each side by '4'.
x = -2.75 + 0.25k
Simplifying
x = -2.75 + 0.25k
Answer:1,240 minutes or 20 1/3 hours.
Step-by-step explanation: there are 31 days in january so 40 x 31=2140
2+2-2*2/2 divide 2/2=
2+2-2*1 multiply 2*1=
2+2-2 add 2+2=
4-2 subtract 4-2=
2
answer= 2
