X = y + 30 (I)
2x + 20 = 3y + 30
2x - 3y = 10 (II)
______________________________
2(y+30) - 3y = 10
2y + 60 - 3y = 10
-y = -50
y = 50
x = y + 30
x = 50 + 30
x = 80
Football team has 80 members, basketball team has 50 members.
Answer:
Yes; $23.10
Step-by-step explanation:
5% of 22 is 1.10 and if you add the tax to the give price it is less than $24
2x + 7 ≤ 3x - 5
Start by keeping the variable x on the left side of the inequality, and move everything else to the right side.
We can do this by subtracting 3x from both sides and subtracting 7 from both sides.
-x ≤ -12
Divide both sides by -1 to make x a positive; when dividing by a negative number you will flip the inequality sign, so ≤ becomes ≥.
x ≥ 12
Possible solutions for x are any number equal to or greater than 12.
