If 67 percent are herbivores, then 33 percent are not.

So we are looking for 33 percent of 925.

Now all we have to do is reduce that to a simple form.

We know that the answer will be around 300ish, because a third of1000 is 333. It's always good to have an idea of what you are looking for.

So if I multiply 925 by 33 and divide the answer by 100, I get the percentage you're looking for. I used a calculator, and got 305.

305 animals are carnivores (not herbivores).

Answer:

$x=-1\text{ or }x=11$

Step-by-step explanation:

For $a=|b|$ , we have two cases:

$\begin{cases}a=b,\\a=-b\end{cases}$

Therefore, for $18=|15-3x|$ , we have the following cases:

$\begin{cases}18=15-3x,\\18=-(15-3x)\end{cases}$

Solving, we have:

$\begin{cases}18=15-3x, -3x=3, x=\boxed{-1},\\18=-(15-3x), 18=-15+3x, 33=3x, x=\boxed{11}\end{cases}$ .

Therefore,

$\implies \boxed{x=-1\text{ or }x=11}$

In a certain region, the equation y=19.485x+86.912 models the amount of a homeowner’s water bill, in dollars, where x is the n

DanielleElmas [232]

Answer:

It's choice 2.

Step-by-step explanation:

y=19.485x+86.912

The 19.485 is the slope of the graph of this equation. This gives the rate of change of the amount of the bill (above $86.912) for each added resident (x).

Solve for x: -7x+2=-4x-7

Zielflug [23.3K]

Answer: x = 3

Step-by-step explanation:

First you need to start by adding positive 4x to both sides since the 4x is a negative. 4x + (-7x) = -3x. Then it is just simply -3x+2 = -7. Since 2 is a positive number subtract both both sides by 2. Then you should get -3x = -9. Then divide both sides by -3 and the answer is x = 3.
