Answer:
Let's choose the three odd consecutive numbers 1, 3, and 5.
3^2=9
1•5=5
9-5=4
Let's try the same thing, but with the numbers 101, 103, and 105.
103^2=10609
101•105=10605
10609-10605=4
So, yes, the square of the second number out of three consecutive odd numbers is four greater than the product of the first and the third numbers.
(1) x represents the number of apples bought, y represents the number of bananas.
(2) each term represents the total costs of a given fruit, so 0.50x is the total cost of apples and 0.30y is total cost of bananas.
(3) The coefficients are unit prices: coefficient 0.50 is the price of 1 apple, 0.30 is the price of 1 banana.
Answer:
x = 9
Step-by-step explanation:
Given
2(x + 5) = 3x + 1 ← distribute left side
2x + 10 = 3x + 1 ( subtract 2x from both sides )
10 = x + 1 ( subtract 1 from both sides )
9 = x
Answer:
Option D. 5x + 12y + 4z is the corrct one.
