Answer:
14x
2
+9
Step-by-step explanation:
Y=180-111=69
x=360-123-70-69=98
That's your answer.
Mike age is 3 less then twice the age of his brother nuke.
M = Mike's age now
N = Nuke's age now
M = 2N - 3
Ten years ago, four times nuke's age was one more mike's age.
M-10 = Mike's age 10 years ago
N-10 = Muke's age 10 years ago
4(N - 10) = 1 + M -10
what are their present ages
find M and N
substitute M = 2N - 3 into 4(N - 10) = 1 + M -10:
4(N - 10) = 1 + [2N - 3] - 10
4N - 40 = 2N - 12
2N = 28
N = 14
M = 2(14) - 3 = 28 - 3 = 25
Mike is 25 and Nuke is 14.
check:
4(14 - 10) = 4(4) = 16 = 26 -10 = 1 + 25 - 10
Step 1:
Work out how much is was for 6 avocados
20 - 10.40 = 9.6
Step 2:
Find out how much it is for 1 avocado
9.6 / 6 = $1.6
Step 3:
Construct an equation, where y is how many avocados
1.6y = total price
