15.5-3.5=12. this is how many hours he has worked already.
12/1⅓=9. this is because how many hours he has worked per how many hours he worked per day to show how many days he worked
the answer is 9 days.
12hours * 1day/1⅓ hours
^^ignore that if it doesn't make sense, but basically the hours will cancel and you'd be left with days as your only unit to show why you would divide 12 by 1⅓
hope this helped!
Answer:
The answer is 3
Step-by-step explanation:
First write the equation as you see it.
-11b+7=40
Then switch the take away seven from the left side then place it in the right side but as a minus.
-11b=40-7
Next do the math on the right side.
-11b=33
Once you have done that you divide the number on right with the number on the left which leaves you with the answer.
b=-3
Hope this helped :)
Answer:
In the table, we can see values of x and y, to complete it, we just need to input the different values of x in the equation:
y = 16*x^2
For example in the first slot, we have x = -4
Then we will have:
y = 16*(-4)^2 = 240
Then we complete the empty slot with 240.
The table would be:
![\left[\begin{array}{cccccccccccccccc}x&-4&-3&-2.5&-2&-1.5&-1&-0.5&0&0.5&1&1.5&2&2.5&3&4\\y&240&\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccccccccccccccc%7Dx%26-4%26-3%26-2.5%26-2%26-1.5%26-1%26-0.5%260%260.5%261%261.5%262%262.5%263%264%5C%5Cy%26240%26%5Cend%7Barray%7D%5Cright%5D)
Now we just need to do the same for the other values:
y(-3) = 16*(-3)^2 = 144
y(-2.5) = 16*(-2.5)^2 = 100
y(-2) = 16*(-2)^2 = 64
y(-1.5) = 16*(-1.5)^2 = 36
y(-1) = 16*(-1)^2 = 16
y(-0.5) = 16*(-0.5)^2 = 4
y(0) = 16*(0)^2 = 0
y(0.5) = 16*(0.5)^2 = 4
y(1) = 16*(1)^2 = 16
y(1.5) = 16*(1.5)^2 = 36
y(2) = 16*(2)^2 = 64
y(2.5) = 16*(2.5)^2 = 100
y(3) = 16*(3)^2 = 144
y(4) = 16*(4)^2 = 240
Then the complete table is:
![\left[\begin{array}{cccccccccccccccc}x&-4&-3&-2.5&-2&-1.5&-1&-0.5&0&0.5&1&1.5&2&2.5&3&4\\y&240&144&100&64&36&16&4&0&4&16&36&64&10&144&240\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccccccccccccccc%7Dx%26-4%26-3%26-2.5%26-2%26-1.5%26-1%26-0.5%260%260.5%261%261.5%262%262.5%263%264%5C%5Cy%26240%26144%26100%2664%2636%2616%264%260%264%2616%2636%2664%2610%26144%26240%5Cend%7Barray%7D%5Cright%5D)
Then we can see that there is a symmetry around the value x = 0.
