Answer:

x= 5

Step-by-step explanation:

You need to get rid of the fraction first and to do that you muliply the whole equation by 5 so that your new equation reads 4x+25=45. Then you subtract 25 from both sides so you have 4x=20. Divide both sides by 4 so x=5.

Which of the following ordered pairs represents a solution to the linear inequality y>2x-3?
devlian [24]

Answer:

B (2, 5).

Step-by-step explanation:

Y is greater than 2x-3.

Check each one in turn:

A. (4,4) ;  y = <u>4</u><u> </u>and 2x-3 = 2(4)-3 =<u> 5.</u> NOT a solution ( y<2x-3 in this case).

B. (2, 5): y = 5 and 2x - 3 = 2(2) - 3 = 1   so y>2x-3 and this point IS a solution.

C. (3, 2)  y = 2 and  2x-3 = 3 - NOT a solution.

D. (9, 12) y = 12 and 2x-3 = 15 - Not a solution.

Need help on #6 step by step I'm so confused how this works I always get stuck
inna [77]
To find the variable x, set the two outside equations equal to each other because all sides are equal
x+13=3x+3
13=2x+3
10=2x
x=5

then to find h, you set the equation equal to 90 because that's how many degrees it is
2h-45=90
2h=135
h=67.5
