The Answer is 6 Dollars
Well here there are two parts You and your friend spent 15 dollars your friends lunch cost 3 more than yours <span>
6=x is the amount you spent on lunch.
Your friend spent $3 more so add $3 to the amount you spent to get...
$9 spent by your friend.
You=$6
Friend=$9
Total=$15
To prove the solution is valid, plug 6 in for x.
15=3+2(6)
15=3+12
15=15 thus proving the solution is valid.</span>
Since 15409-1=15408 and 15408+1=15409, we can write that as one. With 15409-2, we can write the same thing with 15407+2
The answer is B because the base of the triangle is a square as said then three triangles meet up at the point and make a pyramid
Answer:
The value of y is -5
Step-by-step explanation:
we have
------> equation A
------> equation B
we know that
If x and y satisfy both equations, then (x,y) is the solution of the system of equations
Using a graphing tool
Remember that
The solution of the systems of equations is the intersection point both graphs
The intersection point is (2,-5)
therefore
The solution of the system of equations is the point (2,-5)
The value of y is -5
