Step-by-step explanation:
To work this out you will need to find the lowest common factor of 4 and 10 since that is when you get there product and discount, therefore the lcm is 20, and therefore that is your answer (20)!
Answer:
y=4x^2-31
Step-by-step explanation:
Answer:
x=2, y=2
Step-by-step explanation:
3x + y = 8
2x + 4y = 12
Multiply the first equation by -4
-12x -4y = -32
Then add to the second equation
-12x -4y = -32
2x + 4y = 12
------------------------
-10x + 0y = -20
-10x = -20
Divide by -10
-10x/-10 = -20/-10
x =2
Now find y
3x+y = 8
3(2)+y = 8
6+y = 8
y = 8-6
y =2
Solution-
89.50/2 = 44.75
44.75 is the amount he spent to buy his nephew the pair of shoes.
Now, we are going to add the amount he spent for himself and his nephew together.
89.50 + 44.75= 134.25
134.25 is the amount he spent in total, now we need to find the final amount with sales tax included.
We can do this by multiplying the total price by .075
134.25 * .075 = 10.07 (I rounded this to the nearest hundredths because we are dealing with money)
Now we need to add the two number together.
134.25 + 10.07 = 144.32
