Answer:
Science problems= 12
Math problems= 27
Step-by-step explanation:
If
x= math problems for solving
y= science problems for solving
x+y=39
y=x-15
Using substitution method:
x+(x-15)=39
2x-15=39
2x=39+15
x=(39+15)/2
x=27
Having "x" lets find out "y" value.
x+y=39
27+y=39
y=39-27
y=12
C. (22,16)
Y=x-6
16=22-6
16=16
The true option about the solution to the system of inequalities shown is B. The second line has a positive slope and goes through (0, negative 3) and (1, 0).
<h3>
How to explain the inequality?</h3>
Plot these ordered pairs on a coordinate plane and connect them by straight lines.
The sign of both inequalities is "<"which means both lines are dotted and everything below the lines is shaded.
From the below graph it is clear that all values are satisfied.
