Answer:
x= 11
Step-by-step explanation:
or, 9x-18=81
or, 9x=81+18
or, 9x=99
or, x=99/9
or, x=11
The length of concrete patio is 6.5 feet which is less than given 7 foot picnic table. So the concrete slab is not enough to fit a 7 foot picnic table
<em><u>Solution:</u></em>
Given that concrete patio is
feet wide
Area of concrete patio =
square feet
Therefore,

Let us find the length of concrete patio
Concrete patio is usually of shape rectangle
Area of concrete patio = length x width

Therefore length of concrete patio is 6.5 feet
So it cannot fit the 7 foot picnic table. Since the length of concrete patio is 6.5 feet which is less than given 7 foot picnic table
Answer:
C. -2
Step-by-step explanation:
To find the slope of the line we take two points
((0,1) and (2, -3)
and use the formula for slope
m= (y2-y1)/ (x2-x1)
= (-3-1)/(2-0)
= -4/2
= -2
I am going to go on a limb here and say that C, or the third one is incorrect. I would love to say it is A, or the first one, but i'm not completely sure, if it's wrong I am really sorry!
