Answer:
1) 4
2) y <= 9
3) NO SOLUTION
4) 24
5) 5 cards
Step-by-step explanation:
1st pic) 2x + 7 = 15
2x + 7 = 15
<u> -7 -7</u>
2x = 8
divide by 2 to isolate x
<u>x = 4</u>
2nd pic) y - 3 <= 6
y - 3 <= 6
<u> +3 +3</u>
<u>y <= 9</u>
<u />
3rd pic) x + 0.5 = x + 6
x + 0.5 = x + 6
<u> -0.5 -0.5</u>
x = x + 5.5
NO SOLUTION
4th pic) 5m + 10 <= 130
5m + 10 <= 130
<u> -10 -10</u>
5m <= 120
divide by 5 to isolate the m
<u>m <= 24</u>
5th pic) 2c - 8 > 0
2c - 8 > 0
<u> +8 +8</u>
2c > 8
divide by 2 to isolate the c
<u>c > 4</u>
Answer:
Step-by-step explanation:t55
An octagon has 8 sides. If each of them has a length of x, then the perimeter is 8x which is twice the perimeter of the square. (The square has a perimeter of 4x)
A dodecagon is a 12 sided regular polygon. It will have 12 sides all of which are equal to x. Since the square has a perimeter of 4x and the dodecagon has a perimeter of 12x the perimeter of the dodecagon is 3 times that of the given square.
Answer:
$60 dollars
Step-by-step explanation:
x axis is hours spent and y axis is $3 + dollars earned so 15*3 =45 +15 = 60
The slope is 2x and the y intercept is 5
The slope is positive
