Answer:
x =
25
/(1 − sin(y
)) and y ≠
π/2 +2πn
Step-by-step explanation:
Let's solve and simplify for x,
(x − 25
)/ x = sin(y)
Let's multiply both sides by x
((x − 25
)/x) *x= sin(y)*x
Then,
x − 25 = sin(y) * x
Let's add 25 to both sides
x − 25 + 25 = sin(y) * x + 25
If simplify again,
x = sin(y) * x + 25
Then we need subtract sin y x from both sides
x − sin(y) * x = sin (y)* x + 25 − sin (y)* x
It will equal:
x − sin (y)* x = 25
Factor x−sin(y) x: x(1−sin(y) ), then we get:
x (1 − sin(y)) = 25
Finally we need divide both sides by 1 − sin(y) ; y ≠π
/2
+ 2πn
And it will give us this equation:
x =
25
/(1 − sin(y
)) and y ≠
π/2 +2πn
Answer:
right arrow
Step-by-step explanation:
Answer:
∠3≅∠1
∠4≅∠8
∠3& ∠8 are supplementary
Step-by-step explanation:
-4 1÷5 - (- 13 1÷10)
first we should turn these into improper fractions by multiplying the whole number by the denominator then add the numerator.
4 × 5 = 20 + 1 = 21
13 × 10 = 130 + 1 = 131
(-21/5) - (-131/10)
To subtract fractions we want to find a common denominator so we can multiply the numerator and denominator of (-21/5) by 2 to get (-42/10)
(-42/10) - (-131/10)
Since we are subtracting a negative, that becomes a positive
(-42/10) + 131/10
131 - 42 = 89
89/10
Now we can change it back into a mixed fraction:
8 and nine-tenths or 8 9÷10
Answer:
x = 4
Step-by-step explanation:
Given
(x - 7) = - 2
Multiply both sides by 3 to clear the fraction
2(x - 7) = - 6 ← distribute left side
2x - 14 = - 6 ( add 14 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
