Answer:</h3>
12 units²
<h3>
Step-by-step explanation:</h3>
Counting half-squares around the perimeter of the rectangle, we find there are 10. Counting full squares inside the rectangle, we find there are 7. Then the total area is
... (1/2)·10 +7 = 12 square units
_____
<em>Alternate calculation</em>
The long side is the hypotenuse of a right triangle with legs 3, so has length 3√2. The short side is the hypotenuse of a right triangle with legs 2, so has length 2√2. The area is the product of these lengths, so is ...
.. area = (3√2)(2√2) = 6(√2)² = 6·2 = 12 . . . square units
Answer:
26 and 27
Step-by-step explanation:
The first integer = x
Therefore the second integer = x + 1
according to the statement we obtain the equation
(x) + (x + 1) <55
x + x + 1 <55
2 * x + 1 <55
We subtract 1 from both sides, we get:
2x <54
divide both sides by 2 we get:
x <27
Therefore the first integer is 26, since it has to be better than 27.
the second integer = x + 1
= 26 + 1
= 27
If we add 26 + 27 = 53, which is less than 55 and the condition is met

<h3>
Answer:</h3>
5 book covers and 2 boxes of pencils
<h3>
Step-by-step explanation:</h3>
If all 7 were book covers, the cost would be 10.50. The cost is 2.60 more than that. Each box of mechanical pencils costs 1.30 more than a book cover, so there must be 2.60/1.30 = 2 boxes of mechanical pencils (and 5 book covers).
_____
If you want an equation, let p represent the number of pencil boxes. Then 7-p is the number of book covers.
... 1.50(7-p) +2.80p = 13.10
... 1.30p = 13.10 -10.50 . . . . . subtract 10.50, collect terms
... p = 2.60/1.30 = 2 . . . . pencil boxes
... 7-2 = 5 . . . . . book covers
Answer:5000 Ib
Step-by-step explanation:
1 tons=2000 pounds
2.5 tons=2.5 x 2000
2.5 tons=5000 pounds or 5000 Ib
