Answer:
$8.40
Step-by-step explanation:
8.6 plus 8.2 is 16.8 so they had a total of 16.8 ounces. $0.50 per ounce so you need to multiply 16.8 by 0.50 which is 8.40. you can also do 8.6(0.5) plus 8.2(0.5)= 4.3 plus 4.1 = 8.4
So P stands for principle which is the amount of the original investment, R stands for rate which is the percent but must be turned into a decimal, T stands for time for example if the time was in a certain amount of months then you plug that in with x/12, and lastly I stands for interest which is the original investment outcome ^_^
Answer:
k = 4
Step-by-step explanation:
-9 +8k = 7+4k
Subtract 4k from each side
-9 + 4k = 7
Add 9 to each side
4k = 16
Divide by 4
k = 4
Plug in the value you got for k:
-9 + 8(4) ? 7 + 4(4)
-9 + 32 ? 7 + 16
23 ? 23
23 = 23
No error - A and B are completely right, and using the subtraction law D is right
Answer:
The correct answer is 2 23/63
Step-by-step explanation:
To determine how much the plant grew, start by subtracting the starting whole number value from the ending whole number value.
4 - 1 = 3
Now do the same with the fractions. Use common denominators.
2/9 - 6/7
14/63 - 54/63
-40/63
Now add the two numbers together.
3 - 40/63 = 2 23/63
