Answer:
y=4-0.5x
Step-by-step explanation:
Step one:
given data
Alina bought an ice cream cone for $3
the weight of the ice cream is 4 ounce
the rate of melting is 0.5 ounce per minute
let the number of minutes taken for the ice cream to melt be x
and the weight after x minutes be y
Step two:
Hence the expression for the situation after x minutes is
y=4-0.5x
Answer:
85
Step-by-step explanation:
Order of operations rules (PEMDAS) govern here. Anything inside parentheses must be done first, followed by exponentiation, mult. and div., and add. and subtr. last.
Add 2+5 first: 5 + 2*{(7)*5 + 5}
Perform the work shown inside the brackets { and }: 5 + 2*{40}
Perform the indicated mult.: 5 + 80
Finally, add: 85
Answer:
x must be greater than -53/14
(im not 100% sure but i think this is correct)
You simply have to sum the two fraction together to get the total amount of occupied plot. To do so, multiply both numerator and denominator of each fration by the same number, so that they end up having the same denominator.
You can multiply both numerator and denominator of 1/8 by 3 to get 3/24. Similarly, you can multiply both numerator and denominator of 1/6 by 4 to get 4/24.
Now we can easily sum the two fractions together:
So, if 7 parts out of 24 are occupied, it means that there are 
parts left for other crops. So, the answer is 17/24.
