At a bake sale there were 90 items sold total. If 42 of the items sold were cookies and the rest were brownies what is the ratio

kari74 [83]

Firstly, you do 90 - 42 to get the amount of brownies sold, which is 48. Then, you put 42 and 48 into a ratio like 42:48. After that, all you need to do is simplify to get 7:8.

-5 < x - 4 greater than it equal 1

saul85 [17]

We have expression $-5 < x - 4 \geq 1$ that renders the system of inequalities,

$\begin{cases}-5 < x - 4 \\x - 4 \geq 1\end{cases}$

Which can be simplified to,

$\begin{cases}x > -1 \\x \geq 5\end{cases}$

So what we get is something greater than -1 and at the same time greater or equal to 5, so the solution is,

$x\in(\infty,-1)\cap(\infty, 5]=\boxed{(\infty,5]}$ .

Hope this helps.
