To find the answer you will write and equation in terms of the cost of a bag of chips.
3(cost of milk) + 4 (cost of water) + 8 (cost of bag of chips) = $21.30
3 (2c +1.60) + 4 (2c) + 8 (c) = $21.30 ; Simplify
6c + 4.80 + 8c + 8c = 21.30
22c + 4.80 = 21.30
- 4.80 -4.80
<u>22c </u> = <u>$16.50</u>
22 22
c = 0.75
The chips cost $0.75 each.
The milk costs (2 x $0.75 + $1.60) $3.10 each.
The water costs (2 x $0.75) $1.50 each.
Answer:
Step 2
Step-by-step explanation:
Because he didn't solve what was inside of the brackets, which would've been 20 divided by 4 if he did add the numbers inside of the brackets.
You mean to simplify as this is an expression not an equation, as it has no equal sign...
Factor our 4 first
(4r^3t^2)/(-rt)
Now factor out -rt
-4r^2t
Answer:
Hey there!
The range is the possible y-values of any function. That's the definition, but identifying range takes practice, so let me know if you need any help with that.
Hope this helps :)
Answer: 5.738 x 10^7
Solving Steps:
(3.8 x 10^5) + (5.7 x 10^5)
3.8 x 10^5 + 5.7 x 10^5
(3.8 + 5.7 x 10^2) x 10^5
...Rest of work
