The correct answer is $12, \ 40, \ 58$
Even numbers always end with a digit $0, \ 2, \ 4, \ 6$ or $8$.
Therefore, numbers $12, \ 40, \ 58$ are the only even numbers.

4- Choice B is correct

The correct answer is $40$
$8$ rows of chairs with $5$ chairs in each row means: $8 \ × \ 5 = 40$ chairs in total.

$8$ ten thousand $=$ $80,000$
$2$ hundred $=$ $200$
$5$ tens $=$ $50$
Add all: $80,000 \ + \ 200 \ + \ 50 = 80,250$

6- Choice D is correct

The correct answer is $49$
To find the area of a square, multiply one side by itself.
Area of a square $=$ (side) $×$ (side) $=$ $ 7 \ × \ 7 = 49$

7- Choice A is correct

The correct answer is $18$
We need to find a number that when divided by $6$, the answer is $3$.
Therefore, we are looking for $18$.

8- Choice D is correct

The correct answer is $140$ pennies
$2$ quarters $=$ $2 \ × \ 25$ pennies $=$ $50$ pennies
$8$ dimes $=$ $8 \ × \ 10$ pennies $=$ $80$ pennies

The correct answer is $1,120$
$20 \ × \ 56= 1,120$

10- Choice C is correct

The correct answer is $20$
$A$ $=$ $300 \ ÷ \ 15 ⇒ A =20$

11- Choice B is correct

The correct answer is $28$ cm
Use perimeter of rectangle formula.
Perimeter $=$ $2 \ × $ length $+ \ 2 \ × $ width ⇒ P$=$ $2 \ × \ 5 \ + \ 2 \ × \ 9 = 10 \ + \ 18 = 28$ cm

12- Choice C is correct

The correct answer is $x \ -\ 15 =74$
$47 \ – \ x \ = 15$
Then, $x = 47\ – \ 15 = 32$
Let’s review the equations provided:
A. $47 \ – \ 15 = \ x $ This is true!
B. $47 \ – \ x = 15$ This is true!
C. $x \ – \ 15 = 47$ This is NOT true!
D. $x \ + \ 15 = 47$ This is true!

13- Choice A is correct

The correct answer is $1,380$
$30 \ × \ 46 = 1,380$

14- Choice D is correct

The correct answer is $300$ minutes
$1$ hour $=$ $60$ minutes
$5$ hours $=$ $5 \ × \ 60$ minutes ⇒ $5$ hours $=$ $300$ minutes

15- Choice B is correct

The correct answer is $\frac{80}{100}$
The table is divided into $100$ equal parts.
$80$ parts of these $100$ parts are shaded. It means $\frac{80}{100}$ .

16- Choice A is correct

The correct answer is $62$
To find the answer subtract $58$ from $120$. The answer is $(120 \ – \ 58 = ) \ 62$.

17- Choice D is correct

The correct answer is $12$
$25 \ + \ B \ + \ 6 = 43 ⇒ 31 \ + \ B = 43 ⇒ B = 43 \ – \ 31 = 12$

18- Choice C is correct

The correct answer is $\ × $
$2 \ × \ 8 = 16$. Then:
$2 \ × \ 8\ ⎕ \ 4 = 64$
$16\ ⎕ \ 4 = 64 ⇒ 64 = 16 \ × \ 4$

19- Choice D is correct

The correct answer is $650$
We round the number up to the nearest ten if the last digit in the number is $5, \ 6, \ 7, \ 8, $ or $9$.
We round the number down to the nearest ten if the last digit in the number is $1, \ 2, \ 3, $ or $4$.
If the last digit is $0$, then we do not have to do any rounding, because it is already rounded to the ten.
Therefore, rounded number of $645$ to the nearest ten is $650$.

20- Choice D is correct

The correct answer is $80$
$2$ spaghetti with meatballs cost: $2 \ × \ $15 = $30$
$5$ bowls of bean soup cost: $5 \ × \ $10 = $50$
$2$ spaghetti with meatballs $+\ 5$ bowls of bean soup cost: $$30 \ + \ $ 50= $80$

21- Choice A is correct

The correct answer is $750$
$50 \ × \ 15 = 750$

22- Choice C is correct

The correct answer is $90$

23- Choice B is correct

The correct answer is $525 \ - \ 266\ - \ 100 =$_____
Liam gave $266$ of his marbles to his friend.
Now he has $525 \ – \ 266 = 259$
He lost $100$ of his marbles.
Now, he has $259 \ – \ 100 = 159$ or $(525 \ – \ 266 \ – \ 100)$.

Perimeter of the square is $28$.
Then:$28 = 4 \ × \ $side ⇒ side $=$ $7$
Each side of the square is $7$ units.

27- Choice A is correct

The correct answer is $\frac {12}{8}=\frac{3}{2}$
Simplify $\frac{3}{2}$ that’s equal to $\frac{12}{8}$ Only option A is correct.

28- Choice B is correct
