Answer:

Step-by-step explanation:

-5x - 4y = 2a

slope of line is -5/4

4x - 5y = 2

slope of line is 4/5

Since the lines have different slopes, they intersect. There is exactly one solution, regardless of the value of a.

-5/6x = -10/3<br> solve for x
ololo11 [35]

Answer:

x = 4

Step-by-step explanation:

First you need to multiply both sides of the equation by -6/5

-6/5 × (-5/6x) = -6/5 × -10/3

Then you need to calculate and reduce. First, you'll reduce the numbers with the greatest common divisor, 6.

1/5 × 5x = -6/5 × (-10/3)

then reduce the greatest common divisor, 5

x = -6/5 × (-10/3)

Then multiply (multiplying two negatives equals a positive)

x = 6/5 × 10/3

reduce the greatest common divisor, 3

x = 2/5 × 10

reduce the greatest common divisor, 6

x = 2 × 2

x = 4

(i know this is confusing, sorry)

Answer:

28/53

Step-by-step explanation:

Hey There!

So they want us to find the sine of angle S

well remember is sohcahtoa

S - sine

O - opposite

H - hypotenuse

meaning that

Sin=\frac{opposite}{hypotenuse}

The opposite side of angle S is 28 and the hypotenuse is 53

so sinS=\frac{28}{53}
