Answer: 53
Step-by-step explanation:
It would be a 90%. In the calculator 18 is what percent of 20.
F=-50 as multiplying it by -6.2 would give you a positive 310
Part A) If would probably be smart to use substitution because y is already solved for, so we can substitute the value of y as a function of x into the other equation.
y=7x-8
y=5x-2
7x-8=5x-2
+8 +8
-----------------
7x=5x+6
-5x -5x
----------------
2x=6
/2 /2
-----------
x=3
y=7x-8
y=21-8
y=13
Part B) The lines will intersect at point (3, 13), because idk it just makes sense
