Basically you just have to do either $18/4 or $27/6 which gets you to 4.5 which is the unit rate
Let us set up some variables:
Now let us set up some equations based on the facts:
- length of rectangle is 4 times its width --> L = 4W
- perimeter of rectangle is 80 --> 2L + 2W = 80
Equations:
L = 4W -- equation 1
2L + 2W = 80 -- equation 2
Plug the value of L from equation 1 into equation 2
2(4W) + 2W = 80
8W + 2W = 80
10W = 80
W = 8 -- equation 3
Plug the value of W from equation 3 into equation 1:
L = 4W = 4 * 8 = 32
Therefore the length is 32 and the width is 8.
Hope that helps!
Hey! :)
The total cost of the item is the second choice which is $14,372.08. I arrived to the answer by simply:
1) multiplying the sales tax to the negotiated price (15640*.072 = 1126.08)
2) adding the sales tax to the negotiated price and the registration as well (15640+1126.08+106= 16872.08)
3) subtracting the trade in allowance from the computed value (16872.08 - 2500 = 14372.08)
Hope this helps! :)
Answer:
x = -9
Step-by-step explanation:
5x + 4 = -41 Your goal is to get x alone on on side
- 4 - 4 Subtract 4 from both sides to get 5x alone
5x = -45 Now you need to divide to get what x equals
Divide by 5 to get x
