Tell whether (4, 27) is a solution of y=3x+15
Brilliant_brown [7]

Answer:

Yes

Step-by-step explanation:

We have two properties for our question :

(4, 27)

y = 3x + 15

We are being asked whether the point (4, 27) is a solution of y = 3x + 15

So how do we figure this out? Well, what we have to know first that (4, 27)  represents a variable, 4 which is the run on the graph, represents x in a solution. And 27 which is the rise on the graph, represents y in the solution. So when asking for a solution with two points, all we must do is substitute x and y for the two coordinates.

y = 3x + 15

y = 27 and x = 4

27 = 3(4) + 15

27 = 12 + 15

27 = 27

Since this equation is true with the respected variables, therefore signifies that (4,27) is a solution of y = 3x + 15

Solve for x.
kati45 [8]

Answer:

72.5

Step-by-step explanation:

5x5+2x+10=180

1.PEMDAS

2.5x5=25

3.25+10=35

4.Try to get everything away from X so move 35 to other side by subtracting since its a positive number and if negative number (ex. -35) u add, 180-35=145

5. and divide 145 by 2 than finally x is alone which comes out to x=72.5
