Answer:
1739 Reference Books Sold.
Step-by-step explanation:
Do this problem, we have to convert 34% to a decimal by taking the whole number value of the percent then dividing by 100. This gives us 0.34.
We can then take 4700 and multiply it by 0.34 and get 1739.
This also means that 0.66 is left over to be sold that hasn't sold in the month,
Take .66 and multiply it by 4700 to get 3102.
As long as 3102+1739=4700 is true, this means we have accounted for all values in the pie chart. At this point, we know from this that 1739 is the number of reference books sold out of the 4700.

Answer:
Step-by-step explanation:
If you're trying to isolate the variable the first thing you would want to do is actually add 9 to both sides.
It is in standard form: y=mx+b
<em>Answer:</em>
<em>-2<x<4</em>
<em>Step-by-step explanation:</em>
<em>-5<4x+3<19 this is the same as -5<4x+3 AND 4x+3<19</em>
<em>-5<4x+3 subtract 3 on both sides and u get -8<4x</em>
<em>-8<4x Divide four by both sides and u get -2<x or x>-2.</em>
<em>For those of u who are confused when to switch the symbol < or > or etc, the rules are…</em>
<em>when u are dividing by a negative number then switch the symbol. For example, -16/-2 then switch symbol or 16/-2. When it’s -16/2 then don’t switch.</em>
<em>anyways.. the second equation: 4x+3<19 subtract 3 on both sides and u get</em>
<em>4x<16 then divide by 4 each side and u get x<4 if u wanna combine them both then it would be -2<x<4. On a number line, u would use an open circle that is not shaded for both numbers. Label -2 on the left side of zero and 4 on the right. Then connect the not shaded circles together on the number line. I hope u understand how to draw in my explanation if not then tell me and I’ll edit my response! :D</em>
