Step-by-step explanation:
5x + 8 = x - 9
5x - x = - 9 - 8
4x = - 17
x = - 4 1/4
Can you explain the other stuff you wrote down so I can help? Can you put the stuff on a line so I can understand?
I haven't bought it yet but I am considering it, just wondering what the capacity is. I would be keeping tropicals in there, just small things like: neons, glass cat fish and my two mystery fish (see my other questions about them lol) and I would like to buy more neons (I have 6) and more glass catfish (I have two, though I'm looking at my SpyOrb as we speak and I appear to have lost them...they are hiding!). That is my answer
Answer:
Volume is always in cubic units [3]
Volume of the cube is 1/125 in³
Step-by-step explanation:
Volume of a cube can be found by raising a side to the power of 3.
(1/5)^3 = 1/125
The answer is x = 30 mm.
Similar shapes have proportional measurements. Hence:
side AB/side BC = side DE/side EF
1.) Substitute with given:
<span> AB/BC = DE/EF
10/4 = DE/12
2.) Cross multiply </span>10/4 = DE/12<span>
4DE = 120
3.) Divide both sides of the equation by 4 </span>to solve for DE:<span>
4DE/4 = 120/4
DE = 30 mm.
4.) Substitute and cross multiply to check if the values are equal:
</span> AB/BC = DE/EF
10/4 = 30/12
4(30) =10(12)
120 = 120
Answer:
810
Step-by-step explanation:
number of triangles needed = area of rectangle / area of triangle
area of triangle = 1/2 x base x height
1/2 x 6 x 8/3 = 8
area of rectangle = length x width = 90 x 72
90 x 72/ 8 = 810
