Okay. That formula is set up like this: (n / 2) + 7 = 10. First, we subtract 7 from both sides. When that is done, you should get n/2 = 3. Next, you must multiply each side by 2 to isolate the “n”. When you do this correctly, you should get 6. If you need to check the answer, plug it in. When we check it, the number works. n = 6.
Hello,
What we want to do is multiply 1/6 by each value within the parentheses individually.
So, it would be:
(1/6) * (18x) = 3x
(1/6) * (-24) = -4
Together, this would be 3x-4.
Hope this helps!
Answer:
Step-by-step explanation:
Given that prices for a pair of shoes lie in the interval
[80,180] dollars.
Delivery fee 20% of price.
i.e. delivery fee will be in the interval [4, 9]
(1/20th of price)
Total cost= price of shoedelivery cost
Hence f(c) = c+c/20 = 21c/20
The domain of this function would be c lying between 80 to 180
So domain =[80,180]
---------------------------------
Amount to be repaid = 42 dollars
Once he received this amount, the price would be
105+42 =147
But since price range is only [21*80/20, 21*180/20]
=[84, 189]
Since now Albert has 147 dollars, he can afford is
[80,147]
Answer:
They each get 1 3/4 pounds of cashews
Step-by-step explanation:
7 ÷ 4 = 1.75
1.75 ( 1 3/4)
Add 18 each time
first term is -108
an=a1+d(n-1)
d=common difference
a1=startng term
an=-108+18(n-1)
31 term
a31=-108+18(31-1)
a31=-108+18(30)
a31=-108+540
a31=432
31st term is 432
