Answer:
x<20
Step-by-step explanation:
hope this helped, have a Great Day!!
Let x = number of pages holding 2 cards,
y = number of pages holding 3 cards.
So his total number of card would be 2x + 3y, which is given as 18. So we get this equation.
2x + 3y = 18
Subtract 3y from both sides:
2x = 18 – 3y
Divide both sides by 2:
x = (18 – 3y)/2
x must be an integer. So 18–3y must be a multiple of 2. Since 18 is a multiple of 2, 3y is also a multiple of 2. Then y must be a multiple of 2 too.
Let's start with y = 0.
When y = 0, x = (18 – 3(0))/2 = 9.
When y = 2, x = (18 – 3(2))/2 = 6.
When y = 4, x = (18 – 3(4))/2 = 3.
When y = 6, x = (18 – 3(6))/2 = 0.
Thus there are 4 ways to display his figures.
Answer:
12 sides
Step-by-step explanation:
Given that :
Two of the exterior angles are = 60
The rest are each 24 ;
Find n, the number of sides of the polygon
The sum of the exterior angles of a polygon = 360
2 of the angles are 60° each ;
360 - (2 * 60)
360 - 120 = 240°
The remaining sides are 24° each ;
Hence, number of sides that are 24°
240° / 24° = 10 sides
Hence, total number of sides :
10 sides (14° each) + 2 sides (60° each)
10 + 2 = 12 sides
Answer: 360 hours

Answer:
-4x - 30 = -26 Inverse property of addition
Step-by-step explanation:
To move the variable to the left you would subtract the 2x from both sides and you'll be left with -4x - 30 = -26. Adding the negative of a number from the same number (ex. 30 + (-30)) is called inverse property of addition. which we did here but with 2x.
