Associative property and distributive property
The answer is a space contains at
least four points that do not lie in a same plane or not all in the same plane. An axiom is a statement or
proposition that is observed as being established, accepted, or self-evidently
true. In other words, it is any statement or mathematical statement that functions
as a starting point from which other statements are logically derived. So this
can be found on postulate 1 that states “a line containing at least two points;
a plane contains at least three points not all in one line; and a space
contains at least four points not all in the one plane.”
Answer:
22
Step-by-step explanation:
4+18=22 if y is solved for 18 in the equation 4+y= the answer would be 22.
Answer:
3/2(x+y)
Step-by-step explanation:
The cost of 2 DVD is x+y
Divide by 2 to get the cost of one DVD
(x+y) /2
Multiply by 3 to get the cost of 3
3/2(x+y)
the cost for each of jelly beans and each pound of trail mix is $2.5 and $1.75
<u>Step-by-step explanation:</u>
Given A store is having a sale on jelly beans and trail mix. For 3 pounds of jelly beans and 2 pounds of trail mix, the total cost is $11. For 5 pounds of jelly beans and 6 pounds of trail mix, the total cost is $23 . We have to find the cost for each pound of trail mix and each pound of jelly beans.
Let the cost of each pound of trail mix is $y.
and the cost of each pound of jelly beans is $x.
According to question,
For 3 pounds of jelly beans and 2 pounds of trail mix, the total cost is $11.
⇒
→ (1)
For 5 pounds of jelly beans and 6 pounds of trail mix, the total cost is $23
⇒
→ (2)
Solving (1) and (2), we get
3(1 equation)-(2 equation)=0
⇒
⇒
hence,
⇒
⇒
Putting
in
we get ;
⇒
⇒ 
⇒ 
⇒ 
Hence, the cost for each of jelly beans and each pound of trail mix is $2.5 and $1.75 .
