Answer:
x=2 and y=7
Step-by-step explanation:
Step: Solvey=2x+3for y:
y=2x+3
Step: Substitute2x+3foryiny=3x+1:
y=3x+1
2x+3=3x+1
2x+3+−3x=3x+1+−3x(Add -3x to both sides)
−x+3=1
−x+3+−3=1+−3(Add -3 to both sides)
−x=−2
−x
−1
=
−2
(Divide both sides by -1)
x=2
Step: Substitute2forxiny=2x+3:
y=(2)(2)+3
y=7(Simplify both sides of the equation)
(5n+4p)(5n+4p) or (5n+4p)^2
i took the test :p
What is the relative frequency of a student choosing the aquarium? Give your
answer as a decimal rounded to the nearest hundredth. (The hundreths place is two
decimal places. For example, .9543 would be rounded to .95)
