so you want to get x to one side only.
3.4x-5=2.4x
add 5 to both sides
3.4x=2.4x+5
now get x to one side by subtracting 2.4x
so x=5
Answer:

Answer:
80 ft
Step-by-step explanation:
<em>hey there,</em>
<em />
< We know that the rope is 3 pieces long. To make this into an equation, let's just write x + y + z = 150.
Assuming "y" is our second piece, we can tell y = 2x, because it is two times the size of the first piece, which is "x". We also know "z" (our third piece): z = 30.
We can try inputting all the things we know now. x + (2x) + 30 = 150. From here, we can find that x = 40. Since y is our second piece, y = 2x, so 2 x (40) = 80. The second piece would be 80 feet long. >

Answer:
<h2>224 cubic inches</h2>
Step-by-step explanation:
It's a prism.
The formula of a volume of a prism:
<em>B</em><em> - area of a base</em>
<em>H</em><em> - height</em>
We have a triangle in the base.
The formula of an area of a triangle:
<em>b</em><em> - base</em>
<em>h</em><em> - height</em>
We have <em>b = 4in, h = 7in</em>.
Substitute:
Put the value of a base <em>B = 14 in²</em> and the height <em>H = 16 in</em> to the formula of a volume:
