Hey there, hope i can help!

\mathrm{Add\:}99\mathrm{\:to\:both\:sides}  \ \textgreater \  11x-99+99=201-x+99

Simplify
11x=-x+300

\mathrm{Add\:}x\mathrm{\:to\:both\:sides} \ \textgreater \  11x+x=-x+300+x

Simplify again
12x = 300

\mathrm{Divide\:both\:sides\:by\:}12 \ \textgreater \  \frac{12x}{12}=\frac{300}{12}

Simplify once more
x = 25

Hope this helps!

What’s the domain and range?<br><br> An airplane travels at 565 mph.
viktelen [127]

Answer:

<u>Domain:</u>

The domain of this can be any value between 0 to 565 miles per hour

<u>Range:</u>

The reasonable range can be the distance traveled which can be from 0 to 13,560 miles (no plane travel is longer than 24 hours, we assume).

Step-by-step explanation:

Domain is the input, set of x values for the function.

Range is the output, set of y values for the function.

This isn't a function essentially, but it is given that an Airplane travels at 565 miles per hour.

<em>We can say that the domain will be the speed of the airplane and the range would be the distance it travels.</em>

<em />

<u>Domain:</u>

The domain of this can be any value between 0 to 565 miles per hour

<u>Range:</u>

The reasonable range can be the distance traveled which can be from 0 to (565*24=13,560 miles) 13,560 miles (no plane travel is longer than 24 hours, we assume).

Here are the ingredients for a cake. 0.225 kg butter 225 g sugar 225 g flour 0.2 kg eggs 250 g berries How much do the ingredien
viktelen [127]

Answer:

1125.

Step-by-step explanation:

I'm going to work out the answer is <u><em>grams</em></u>.

1kg = 1000g

0.225kg of butter = 225g, 225g of sugar, 225g of flour, 0.2kg of eggs = 200g, 250g of berries.

225 + 225 + 225 + 200 +250 = 1125.

Hope that helps. x

Can someone help me understand this question?
JulijaS [17]
Hey there! 

For Part A, because the amount earned on Sunday isn't specified, we can call this additional income x. Because we're writing an expression, we don't need an equal sign. The expression will be (x + 14). 

For Part B, "2 less than" will mean "– 2" and "twice than" will mean the amount of dogs that Alicia walked times 2. We can call the amount that Alicia walked y to avoid confusion with the last expression (though you could use whatever variable here) and your expression will be (2y – 2). 

Hope this helped you out! :-)
