Answer:
4 1/4 + 3 1/4 = 7 1/2
Step-by-step explanation:
To make 1/4 to 1/2 You would need 1/4, because 2/4 make 1/2
7-4= 3 so therefore you would have 3 1/4
using a graphical tool the solution is (2,3) see the attached figure
proceed to check it
<span>
f(x)=2x−1
g(x)=−x+5
</span><span>f(x)=g(x)
2x-1=-x+5
2x+x=5+1------------ >3x=6-----------> x=2
y=2x-1=2*2-1=3
the solution is the point (2,3) (</span>see the graph in the attached figure)
A linear equation looks like any other equation. It is made up of two expressions set equal to each other. ... When you find pairs of values that make the linear equation true and plot those pairs on a coordinate grid, all of the points for any one equation lie on the same line. Linear equations graph as straight lines.
