what is 2/3 of 16 (please and thank you)
Answer:
_
10.6
hope dis helps ^-^
The requried value of 2/3 fraction of 16 is 10 and 2/3, or approximately 10.67.
To find 2/3 of 16, you can multiply 16 by the fraction 2/3:
(2/3) * 16 = (2 * 16) / 3
Now, calculate the numerator:
2 * 16 = 32
So, the result is:
(2/3) * 16 = 32 / 3
Next, simplify the fraction:
(2/3) * 16 = 10 and 2/3 or 10.67 (rounded to two decimal places)
Therefore, 2/3 of 16 is 10 and 2/3, or approximately 10.67.

Answer:
2w+4=35
Explanation:
If we use W as the variable to represent the two bags of equal weight, you would put 2w, which represent the two bags. Since the package is 4 kg, the equation would then become 2w+4=35 as the total weight if the baggage James has is 35 kg if you combine the weight of the package and the checked bags
Answer:
D) 2 W + 4 = 35

Hannah read 14 fewer pages than she was assigned to read. She reads 60 pages. Write and solve an equation to find how many pages, p Hannah was assigned to read.
Answer:
74
Step-by-step explanation:
p-14=60. add 14 on both sides to get p=74
26 – x = 14. what is x
Answer:
x=12
Step-by-step explanation:
start with this equation:
26-x=14
it's best to make the x variable positive at all times.
to do that, you need to make everything else positive.
-26+x=-14
then add 26 to both sides.
x=-14+26
which basically says 26-14...
x=12

5 X 1.25 = 6.25
10 - 6.25 = 3.75
