'is' in mathematics means the equal sign
'of' in mathematics means the multiplication sign
the number can be any variable you chose it to be
Divide both sides by 28
Multiply by 100 on both sides to isolate 'x'
14 is 28% of 200

Answer:
1) x>4
2)x≤3
3)x<3
Step-by-step explanation:
1)2x+5>13
2x+5-5>13-5 subtract 5 from both sides
2x>8 results from the previous step
2x/2>8/2 divide 2 from both sides
x>4 final answer
for graphing on the number line it is a closed circle so draw anything bigger than 4 so an open circle and arrow going on forever from four on
2) 5x-7≤8 add seven to both sides
5x≤15 divide both sides by 5
x≤3
for number line, it will be a closed circle at 3 and an arrow pointing forever into the smaller than 3
3)5>4x-7 add 7 to both sides
12>4x divide by 4 on both sides
3>x
for number line 3 is bigger then x so x will be anything smaller then 3 o a open circle on three and the arrow going smaller them 3
4)5x-1<9 add 1 to both sides
5x<10 divide by 5
x<2
xis smaller then 10 so open circle and on forever lower then 10
