Answer:
We would need to add 90+10 first instead of 10+4.8.
Step-by-step explanation:
When evaluating expressions, we follow the order of operations:
P (parentheses); E (exponents); M/D (multiplication/division from left to right); and A/S (addition/subtraction from left to right). The first thing we look for is parentheses.
When we use the associative property as Morgan did to rearrange the problem, this changes the order we begin in. It does not, however, change the answer.
Answer:
45
Step-by-step explanation:
Answer: 600 bushels of 10% alcohol content and 400 bushels of 15% alcohol content.
Step-by-step explanation:
Let we add x quantity of 10% of alcohol content and y quantity of 15% alcohol content for making 12% of alcohol content mixture.
Then according to the question, 10% of x + 15 % of y = 12% of 1000
⇒ 0.1x + 0.15y = 120
⇒ 10x + 15y = 1200
⇒ 2x +3y = 2400 -------- (1)
And, x + y = 1000
⇒ 2x + 2y = 2000 ---------(2)
Equation 1) - equation 2)
We get y = 400
By putting the value of y in equation 1),
⇒2x + 1200 = 2400
⇒ 2x = 1200
⇒ x = 600
Thus, he needs to mix 600 bushel of 10% of alcohol content with 400 bushels of 12% of alcohol content for getting 1000 bushels of 12% of alcohol content.
