Answer:

1. (29 + 19) ➗ 3

     (48) ➗ 3

     48➗ 3

There are 16 cards in each pile

Step-by-step explanation:

2. 14           3. 110           4. 71       5. 54          6. 16            7. 23

8. 75          9. 32           10. 22     11. 20         12. 48          13. 53

14. Spit 6 in half to get Melinda's length so the answer is 3

15.  No the answer is not the same because you have to minus 18 to 8 (which is in the parenthesis) so the answer is 10.  But the other way around you have to add 15 (which is in the parenthesis) plus 5.

I really hope I helped you

Solve for x in the diagram
Aliun [14]

Answer:

x=12

Step-by-step explanation:

The two angles shown are complementary angles, so the add to 90 degrees

x+42 + 3x = 90

Combine like terms

4x+42 = 90

Subtract 42 from each side

4x+42-42 = 90-42

4x = 48

Divide by 4

4x/4 = 48/4

x = 12

the length of a rectangle is 4cm langer than the width. the perimeter is 80cm. what is the length and the width?
Lisa [10]
Let us assume the width of the rectangle = x cm
Then
The length of the rectangle = (x + 4) cm
It is already given that
Perimeter of the rectangle = 80 cm
Now we also know the formula for perimeter of a rectangle
Perimeter = 2 ( length + width)
80 = 2 (x + 4 + x)
80 = 2 (2x + 4)
80/2 = 2x + 4
40 = 2x + 4
Dividing both sides by 2 we get
20 = x + 2
20 -2 = x
x = 18
Then
Width of the rectangle = 18 cm
Length of the rectangle = (18 + 4) cm
                                     = 22 cm
So the rectangle has a length of 22 cm and a width of 18 cm.
