Dontcha mean how many grams are in a pound
the answer is C. 7 because 328 divided by 50 is 6.56 so it would round to 7
The two problems are almost identical: you have to set up a system, and then solve it.
In the first case, let
and
be, respectively, the number of girls and boys.
We know that
(the number of girls in the Spanish Club is four more than twice the number of boys). Also, we know that
(there are 61 students in total).
So, we have the system

We can use the first equation to substitute in the second

And then solve for
:

For the second problem, let
and
be the number of pins knocked down by, respectively, Carrie and John. Just like before, we have the system
And you can solve it in the very same way we solved the previous one.
6/9 is equal to 2/3 is equal to 4/6. Equivalent fraction visually. Equivalent fractions on the number line. Equivalent fractions on the number line.
X less than 10 is the answer I think
