#16: Let's clear the fraction on the way to solving this inequality for x. By mult. the given inequality by 2, we'll get -2 (is greater than) x+4. We want x to be positive. So, leave it where it is. Subtract 4 from both sides of this inequality. We end up with -6 (is greater than) x, which is the same thing as x (is less than) -6. What would the graph of that simple inequality look like?
Graph it. (Hint: The graph is a straight dashed line, and you must shade one side of it, but not the other side.
Answer:
640
Step-by-step explanation:
you say 100% = 800
what about 80%(i get 80% after substracting 100% that's marked price - 20% discount)
then u say 80×800÷100
A=1/2 (b1+b 2)(h) is the area of a trapezoid
Answer:
The answer is C
Step-by-step explanation:
117 + 23 =140 and you have $140 in all so you spent it all
The third one is a point with the first equation.
I had to simplify the second equation.
It simplified to,

The second one with the above is didn't go through so I'd say no solution.
