1. Algebraic expression, it consists of a number and a variable
2. The number of times Chris washes the car
3. 28
4. 85
5. 23.9
Write the equation out: (total cost: 0.35C[per carton] + 75[delivery charge]) ≤ 500. Subtract 75 on both sides and it would be: 0.35C ≤ 425. Divide 0.35 on both sides and you'll get C ≤ 1214. Therefore, the maximum # of cartons that Elvira can buy is 1214 cartons of milk.
360 is the anwer because i multipled 40 white cars by 9 times yellow car to get answer 40×9=360
D. 1/4
Explanation:
a perfect square is written in the form
(1)
In our problem, we have this perfect square:
(2)
with C being unknown. However, by comparing (1) and (2), we know that
So, we find
and therefore, the missing term must be
so the complete square is
Since the blue marbles are 11 and the red marbles are 7 you start will the red marbles first because the question say red marbles to blue marbles
7:11
