Answer:
x = 8 hours
Step-by-step explanation:
add up all the parts,
the teachers spends 24 hours in a day to do 18 parts
there are 2 parts for grading per day, we need to solve for 3 days so 3*(parts) or 6 parts for grading
use ratio to solve for x,
24 hrs x (hours)
______ = __________
18 parts 3*(2 parts)
solve for x = (24 * 6 )/ 18 = 8 hours
Answer:
55w+145
Step-by-step explanation:
10w+120+45w+25 = 55w+145
3 minutes = 2850
5 minutes = 4750
In 8 minutes he descended = 7600
1 min = 7600/8 = 950ft per min
Hope i become the brainliest answer.
<span><em>Partial product </em>multiplication is the process of multiplying the numbers partially (respectively to ones, tens and hundreds) and adding them together in the end. For example, in order to find the product of 3 8 × 6 we should write that,
1) 3 8
× 6
___
4 8
2) 3 8
× 6
_____
4 8
1 8 0
3) 3 8
× 6
______
+ 4 8
1 8 0
______
2 2 8
<em>Regrouping </em>is the multiplication process when we add the partial products to the next tens and hundreds and so on without writing them down. For example, in order to find the product of 3 8 × 6 with the help of regrouping, we write that
4
3 8
× 6
___
228
, where the number 4 above 8 shows the tens of 4 (40), which is going to be added to the tens of the product of 30 times 6. The two processes are the same in a way that you are getting the same result. In the end, it is a multiplication process. The processes differ because of the methods we apply. In partial product multiplication, we break down the number in its ones, tens, hundreds steps and then calculate. However, in regrouping process we consider those steps without breaking them down. </span>
Answer: 6x^2+28x+32
Step-by-step explanation:
Distributive Property: (2x*3x)+(2x*8)+(4*3x)(4*8)=
Simplify: 6x^2+16x+12x+32=
6x^2+28x+32
