Answer:B)The values of both x and y will be real numbers greater than or equal to 0.
Step-by-step explanation:
<span><u>3(x-6)=10x+3</u></span>
Expand the left side:
3x-18 = 10x + 3
Subtract 3x from each side:
-18 = 7x + 3
Subtract 3 from each side:
-21 = 7x
Divide each side by 7 :
<u>-3 = x</u>
Let C = cost to rent each chair
Let T = cost to rent each table
4C + 8T = 73
2C + 3T = 28
Multiply the 2nd equation by (-2) and then add the equations together
4C + 8T = 73
-4C - 6T = -56
2T = 17
T = 17/2 = 8.5
Plug this in to the 1st equation to solve for C
4C + 8(17/2) = 73
4C + 68 = 73
4C = 5
C = 5/4 = 1.25
So the cost to rent each chair is $1.25 and the cost to rent each table is $8.50
An axiom in Euclidean geometry states that in space, there are <u>2</u> points that <u>lie on the same line</u>.
This is called the two-point postulate. According to Euclidean geometry, in space, there are at least two points, and through these points, there exists exactly one line. This means that there is only one single line that could pass between any two points. This is a mathematical truth. It is known as an axiom because an axiom refers to a principle that is accepted as a truth without the need for proof.
Answer:
$0.3 per cookie
Step-by-step explanation:
a dozen is 12 cookies. 2*12 = 24.
7.20/24 = 0.3
so each cookie costs 0.3 dollars
