Answer:
It will take Jack 16 weeks to save enough money to buy the computer.
Step-by-step explanation:
To find the answer, we can divide the cost of the computer ($960) by the amount of money Jack is saving per week ($60), which leaves us with the number of weeks it will take him to save enough money to buy the computer (16).
To check this math, we can multiply the amount of money Jack is saving per week ($60) by the number of weeks it will take him to save enough money to buy the computer (16), which gives us the cost of the computer ($960) and tells us that this answer is correct.
So you would but a b on the outside and on the inside, you would put 8b because b x 8b makes b^2. Then, you would put +7 for the 7b and then close the brackets and thats your answer b(8b+7)
The solution is x= 3 and y = 1
Step-by-step explanation:
Given equations are:
From equation 1:
Putting in equation 2:
Dividing both sides by -9
Putting y = 1 in equation 1:
Hence,
The solution is x= 3 and y = 1

Here is how you are going to add the given polynomials:
3x^4 - 2x^3 -11
12x^4 +x^2 +1 <<< Add these using the normal addition process
----------------------------------
15x^4 - 2x^3 +x^2 -10
Therefore, the answer would be the last option: <span>15x4 – 2x3 + x2 – 10
