P = L + L + w + w
72 = 2(L) + 2(L-4)
Distribute
72 = 2(L) + 2(L) - 8
Add like terms
72 = 4(L) - 8
Subtract 8 from both sides
64 = 4(L)
Divide both sides by 4
16 = L
The length is 16. Now substitute that in the equation for finding w.
w = L - 4
w =
Answer:
x = 24.7
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp side/ adj side
tan 20 = 9/x
x tan 20 = 9
x = 9/ tan 20
x = 24.72729678
Round to the nearest tenth
x = 24.7
Answer:
Five bags would cost $23.75
Step-by-step explanation:
We first need to figure out how much one bag of dog food costs. To do this, we need to do
This answer is $4.75 for each bag of dog food.
Now since we are buying 5 bags of dog food, we would multiply 5 by $4.75: = $23.75.
Therefore, it will cost us $23.75 to buy 5 bags of dog food. Hope this helped!
-4.5 rose 9.7 then fell 4.8
-4.5 + 9.7 = 5.2
5.2 - 4.8 = 0.4
