Pen=x
Pencil=y
y+0.15=x
y+x=0.69
y+y+0.15=0.69
2y=0.69-0.15
2y=0.54
y=0.54/2
y=0.27 pencils
y+0.15=x
0.27+0.15=x
0x=0.42 pen
150 pencils x0.27=40.5$
225 pens x 0.42=94.5$
Total 40.5$ + 94.50$=135 $

Answer:
40 possible answers
Step-by-step explanation:
20 answers from the 10 true or false questions and 20 answers from the 5 multiple choice questions
Step-by-step explanation:
First you must simplify the equation:

subtract 1 from both sides:

than divide both sides by -3, which switches the inequality sign:

This inequality means that all values of x greater than -2 work for the equation. because it is not
, -2 is not included, so there will be a hollow circle there. than the inequality will have a line from that dot to the right so that all values of x that work for the inequality are on that line.
.
you need 2 multiples so you could do 7 x 6
