If the ratio of y to x is equal to 3 and the sum of y and x is 80, what is value of y

Rus_ich [418]

Answer:

y = 60

Step-by-step explanation:

<h3>Step 1: Make sense of the given</h3>

"The ratio of y to x is 3"

This means that, $y\div x=3$

"The sum of y and x is 80"

This means, $x+y=80$

<h3>Step 2: Make use of the facts</h3>

If $y\div x=3$ , then $y = (3*x)$ .

We can plug this into the other equation by substitution:

$x + (3 * x)=80$

This simplifies to:

$4x = 80$

Which we can solve out and get:
$x=20$ .

We solved for x, but we need the value of y.

So, we go back to the equation we first derived: " $y = (3*x)$ ".

And now we substitute the value of x, into this.

$y = (3 * (20))$

By solving this out, we get:
$y=60$

So, the value of y is 60.

HELP !!!!!!!!!!!!!!!!

Fantom [35]

Answer:

∠2 = 51°

Step-by-step explanation:

The sum of supplementary angles = 180°

Equate the sum of the angles to 180 and solve for a

11a + 19 + 6a - 9 = 180

17a + 10 = 180 ( subtract 10 from both sides )

17a = 170 ( divide both sides by 17 )

a = 10

Hence

∠2 = (6 × 10) - 9 = 60 - 9 = 51°

HELP ASAP PLEASE

Liula [17]

distance : 15 units

coordinates : (7,0) and (-8, 45)

slope:

$\sf \rightarrow \dfrac{y_2-y_1}{x_2-x_1}$

$\sf \rightarrow \dfrac{45-0}{-8-7}$

$\sf \rightarrow -3$

equation:

$\hookrightarrow \sf y - 0 = -3(x-7)$

$\hookrightarrow \sf y = -3x+21$

the y-intercept of this function:

$\hookrightarrow \sf y = -3(0)+21$

$\hookrightarrow \sf y =21$

distance between both y-intercept :

21 - 6
