Answer:
35w^3 + 44w
<em><u>Combine Like Terms:</u></em>
= 35w + 9w + 35w^3 + 25w^3 - 25w^3
= (35w^3 + 25w^3 - 25w^3) +(35w + 9w)
= 35w^3 + 44w
Hope this is right ♡
Answer: Susan has 105 dollars
Step-by-step explanation:
dozen is 12, 12 times 4 is 48, 48 divided by 4 is 12, 12 times 8.75 is 105
The best thing to do is to find what 1% is, and you can do this by dividing 150 by 100.
150/100= 1.5
As you're looking for 6.5%, you've got to multiply 1.5 by 6.5
1.5*6.5= 9.75
You've then got to add 9.75 and 150 together
150+9.75= $159.75
Therefore, after the sales tax, the cost of the necklace is $159.75
Hope this helps :)
Answer:
4 + 36x is your expression
Step-by-step explanation:
4 x 1 = 4
4 x 9x = 36x
so 4 + 36x is your expression because you can't add numbers with different variables or if they don't even have one.
The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second
Step-by-step explanation:
We have to calculate his unit rate for both type of races
So,
<u>Unit rate for 400m race:</u>
Distance = 400m
Time = 43 sec
![Unit\ rate = U_1= \frac{Distance}{Time}\\=\frac{400}{43}\\=9.30\ meters\ per\ second](https://tex.z-dn.net/?f=Unit%5C%20rate%20%3D%20U_1%3D%20%5Cfrac%7BDistance%7D%7BTime%7D%5C%5C%3D%5Cfrac%7B400%7D%7B43%7D%5C%5C%3D9.30%5C%20meters%5C%20per%5C%20second)
<u>Unit rate for 300m Race:</u>
Distance = 300m
Time = 31 sec
![Unit\ Rate= U_2=\frac{300}{31}\\=9.68\ meters\ per\ second](https://tex.z-dn.net/?f=Unit%5C%20Rate%3D%20U_2%3D%5Cfrac%7B300%7D%7B31%7D%5C%5C%3D9.68%5C%20meters%5C%20per%5C%20second)
The difference between both unit rates is:
![U_2-U_1 = 9.68-9.30\\=0.38 => 0.4\ meters\ per\ sec](https://tex.z-dn.net/?f=U_2-U_1%20%3D%209.68-9.30%5C%5C%3D0.38%20%3D%3E%200.4%5C%20meters%5C%20per%5C%20sec)
Hence,
The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second
