Answer:
-3.5
Step-by-step explanation:
2x+21/2=x+7
2x + 10.5 = x + 7
-x -x
x + 10.5 = 7
-10.5 -10.5
x = -3.5
Answer:
x=12
Step-by-step explanation:
We know that a right angle is 90 degrees. So we can make the equation 
Now, we can solve fore X! We can combine 35 and 7 to make the equation 
. In order to isolate x we have to subtract 42 from both sides, getting us the equation 
Now, in order to isolate x we must divide each side by 4, getting us the equation 
. To prove that x=12, we can subsitute x for 12. This means that we can do 
which simplified, is 90=90, making x=12 true. Hope this helps :)
Answer:
x= -8
Step-by-step explanation:
for vertical lines the answer is x= whatever point intercepts the x-axis
1st round table has a center located ate (-4,6)
radius is 4 feet and each unit is equal to one foot.
edge of the round table will land at (-8,6)
an additional 5 feet must be added to give space for the guests to walk between tables.
edge of the 2nd table to the left of the 1st table, (-13,6)
to get the center of the 2nd round table, add 4 feet: distance (-17,6)
The center of the table found immediately to the left of the 1st table is (-17,6)
Answer:
Step-by-step explanation:
We are asked to convert 36 inch to feet using dimensional analysis.
We know that 1 feet equals 12 inches.
Let us convert 36 inches to feet as shown below:
Inches will cancel out, so we will get:
Therefore, 36 inches equal to 3 feet.
