Answer:
47
Step-by-step explanation:
The order of operations is encoded in PEMDAS, or Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction. Because there is only addition and subtraction, we just calculate it from left to right: 42 + 7 - 2 = 49 - 2 = 47.
Answer:
97 minutes
Step-by-step explanation:
There are 60 minutes in an hour.
60+37=97
I believe the answer is 4,410. Correct me if I'm wrong. But, I divided 12,600 by 200 and got 63. Then I multiplied the 63 by 70 to get 4,410
The length and width are unknown.
Let the width = w.
The length is 1 more than 3 times the width.
3 times the width is 3 * w = 3w
1 more than 3 times the width is 3w + 1
We have length = 3w + 1, and width = w
The perimeter is the sum of the lengths of the 4 sides, two lengths and two widths.
P = L + L + W + W
P = 3w + 1 + 3w + 1 + w + w
Combining like terms, we get
P = 8w + 2
We are told the perimeter is 58 in., so we set our expression for the perimeter equal to 58
8w + 2 = 58
Now we solve for w, the width.
8w = 56
w = 7
The width is 7 in.
Now we solve for the length.
L = 3w + 1
L = 3(7) + 1 = 21 + 1 = 22
The length is 22 in.
The width is 7 in.
