marin [14]

1) x = 5y - 30  

2) x = - 1.6y + 3.3

<em>im assuming these are 2 different questions</em>

<h3>Explanation:</h3><h3>1)</h3>

Start with the equation:

x - 5y= -30

add 5y to both sides:

x = 5y - 30

Your answer is x = 5y - 30  

<h3>2)</h3>

Start with the equation:

3x+5y=10

subtract 5y from both sides:

3x = -5y + 10

divide by 3 to get x singular

x = - 1.6y + 3.3

Your answer is x = - 1.6y + 3.3

Hope this helps :)

HELP ME PLS ON THIS QUESTIONNN!!!!!!!!!!!!!
sp2606 [1]

Step-by-step explanation:

area of trapezoid = 1/2 × (a+b) h

where a = long base

b = short base

h = height

given that, a = 8, b = 5, a of trapezoid = 104:

area of trapezoid = 1/2 × ( 8+5) h

104 = 13/2 h

104 * 2 = 13 h

13 h = 208

h = 208 / 13

h = 16.0 ft.

hope this helps you!
