100 and 50 is it two answers or just one? bc i’ll fix the answer
Hey there!☺
When you are solving an equation, it is important to use <em>inverse</em> operations. You will need to use the <em>inverse</em> operations on both sides of the equation. And it is also important to isolate the variable. After you do that, you will need to reverse it up. The way to do all of this is using the <em>inverse</em>.
To solve an equation, you use <u>inverse</u> operations.
Hope this helps!
Answer:
It's the first one, the one that has the triangles.
Step-by-step explanation:
They only have a difference of 2. Multiplying the small one by 2 equals the larger one. Doing the opposite and dividing 2 by the larger one gives you thee small triangle. they both have the same angles which makes them similar.
Let x represent the width. Since the length is 3 more than 4 times the width, that would be equal to 3+4x. The perimeter is the sum of all sides, so that would be x+x+3+4x+3+4=86. Combine like terms, which would result in 10x+6=86. Subtract 6 from both sides giving you 10x=80. Divide by 10 giving you x=8. That means that the width is 8. The length is 3+4x. Substitute 8 for x giving you 3+4(8). Multiply, giving you 3+32, then add, which would give you 35. 35 is the length.
What do you mean this sentence?
the time a pump takes to drain the pool varies inversely with the power in watts of the pump,
The meaning would be : if we have a power in watts greater the time to drag the pool will be less because the relation between power and time is inverse.
40 watts--------------5 hours)
100 watts------------ x
because the relation between power and time is inverse, we multiply directly.
40 watts(5 hours)=100 watts x
x=(200 watts hours) / 100 watts=2 hours.
Answer: the time would be 2 hours. (the new pump is faster)
