Answer:
2(x - 3) = 2x + 5
Multiply out the left side:
2x - 6 = 2x + 5
Subtract 2x from both sides:
-6 = 5
Since this is impossible, this "equation" cannot be solved.

<h3>Solution:</h3>
We know the value of x and y,
x = 6 and y = -1 [Given]
<u>Substitute the </u><u>value,</u>
- 4x + 5y
- 4(6) + 5(-1)
- 24 + (-5)
- 24 - 5

It is right
Answer:
-63/16
Step-by-step explanation:
csc x = 5/3
sin x = 3/5
So x is the angle in a 3-4-5 triangle, opposite of the 3.
cos y = 5/13
So y is the angle in a 5-12-13 triangle, opposite of the 12.
tan(x + y) = (tan x + tan y) / (1 − tan x tan y)
tan(x + y) = (3/4 + 12/5) / (1 − (3/4)(12/5))
tan(x + y) = (3/4 + 12/5) / (1 − 9/5)
tan(x + y) = (15 + 48) / (20 − 36)
tan(x + y) = -63/16
Answer:
D
Step-by-step explanation:
Let's call the width of the yard x and the length x + 3½. Since we know that perimeter = 2 * (width + length) and that the perimeter must be 26 we can write:
2 * (x + x + 3½) = 26
x + x + 3½ = 13
2x + 3½ = 13
2x = 9½
x = 4
