Answer:
Anna has $36.39 dollars.
Step-by-step explanation:
All we have to do is subtract
54 - (26.34 + 1.27) =
54 - 27.61 =
36.39
So, the answer is 36.39
Hope this helps! :)
Answer:
18.3
18.3 only has three significant figures while the other numbers have more
Answer:
The equation is : r + 2 = 7
Step-by-step explanation:
1+1+1+1+1+1+1 = r + 1 +1
7 = r + 2
R = 7-2
R = 5
Answer:
The length is 23 inches and the width is 6 inches.
Step-by-step explanation:
The perimeter for a rectangular shape is represented as:
P = 2L + 2W, where L represents length and W represents width
We can represent the length as:
L = 3W + 5
Substituting this into the perimeter function, we get:
P = 2 (3W + 5) + 2W
Substituting 58 for P, we get:
58 = 2 (3W + 5) + 2W
58 = 6W + 10 + 2W
58 = 8W + 10
58 - 10 = 8W + 10 - 10
48 = 8W
48 / 8 = 8W / 8
6 = W
With 6 being the established value for the width, we can substitute this back into the equation for length:
L = 3W + 5
L = 3(6) + 5
L = 18 + 5
L = 23
To check our work, we can substitute both the width and length into the perimeter equation:
P = 2L + 2W
58 = 2(23) + 2(6)
58 = 46 + 12
58 = 58
Therefore, length is 23 inches and the width is 6 inches.
