1. Write an Expression with a Value of 12. it should contain four numbers and two different operations.2. Place Parentheses,if needed, to make each statement true.

1. 7 + 3 x 2 + 4= 25

2. 8 (a Two Above the 8) Divided by 4 x 8 = 2

3. 16 + 8 - 5 x 2 = 14

Answers

Answer 1

Answer:

Answer:

1) $2*2+4+4=12$

2 )Below statements are true

1. 7 + 3 ×(2 + 4)= 25

2. $(8^2)/(4*8)=2$

3. 16 + 8-(5×2)= 14

Step-by-step explanation:

1) To write an expression with a value =12 it should contain four numbers and two different operations.

$2*2+4+4=12$

2) Place Parentheses,if needed, to make each statement true.

1. 7 + 3×2 + 4= 25

In this statement one parentheses is missing i.e. bracket

New statement → 7 + 3 ×(2 + 4)= 25

7 + 3 ×2 +3× 4= 25

7 + 6 + 12= 25

25=25 now, the statement is true.

2. 8 (a Two Above the 8) Divided by 4 x 8 = 2

This statement (a Two Above the 8) means $8^2$

so, $(8^2)/(4*8)=2$

$(64)/(4*8)=2$

$2=2$

The statement is true.

3. 16 + 8 - 5×2 = 14

The statement is true when we solve by BODMAS

i.e. 16 + 8-(5×2)= 14

16 + 8-10= 14

24-8=14

14=14 statement is true

Answer 2

Answer: 1) 2*2+4+4=12
2) 1. 7 + (3 x 2) +25
2. 2/8 divided by (4x8) =2
3. 16+8 -(5x2)=14

hope this help...

The vertices of a parallelogram are shown below. (0, 0), (27, 0), (36, 30), (9, 30)

Which of the following points is a vertex for the image produced by a dilation about the origin with a scale factor of 1/3?

A.

(3, 3)

B.

(10, 9)

C.

(3, 15)

D.

(3, 10)

Answers

The vertices for the dilated image can be found by multiplying the coordinates of the original image by the scale factor. In this problem, the scale factor is 1/3.

(0,0) ⇒ 0 x 1/3 = 0 ; 0 x 1/3 = 0 ⇒ (0,0)
(27,0) ⇒ 27 x 1/3 = 9 ; 0 x 1/3 = 0 ⇒ (9,0)
(36,30) ⇒36 x 1/3 = 12 ; 30 x 1/3 = 10 ⇒ (12,10)
(9,30) ⇒ 9 x 1/3 = 3 ; 30 x 1/3 = 10 ⇒ (3,10)

Answer is choice D. (3,10)

There are 3 grams of fiber in half cup of oatmeal. there are 1 and 1 eight cups of oatmeal left in a box. determine the approximate number of grams of fiber left in the box. show your work with pictures and explain how you found the number of grams of fiber left.

Answers

There are 3 grams of fiber in 1/2 cup of oatmeal. Therefore, the number of grams of fiber in 1 (which is twice as large as 1/2) cup of oatmeal is:
3 g fiber *2= 6 g fiber.

There is 6 g fiber in 1 cup of oatmeal. Therefore, the number of fiber in 1 1/8 (which is 1 1/8 times as large as 1) cups of oatmeal is:
6 g fiber *(1 1/8)= 6.75 g fiber.

There is 6.75 g of fiber left in the box.

Hope this would help~

Answer=6 3/4 grams

3 grams of fiber x fiber
______________=_________
1/2 cup 1 1/8 cup

Cross multiply
1/2x=3 3/8
divide both sides by 1/2
x=6.75 or 6 3/4
There is 6 3/4 grams of fiber in 1 1/8 cups of oatmeal.
