F(x)+g(x)=(x+5)+(11x-5)=x+11x+5-5=12x using the commutative property.
Answer:
you have to show the diagram ...
Step-by-step explanation:
Your equations would be 3x+1y=86 and x+y=42
the answer would be 22 field goals and 20 extra points.
Let the number of corn acres be xx and the number of wheat acres be yy.
We are given that:
1- The total number of acres is 180, this means that:
xx + yy = 180 ..............> equation I
2- The number of corn acres is 3 times that of wheat. This means that:
xx = 3yy .........> equation II
Substitute with equation II in equation I to get the value of yy as follows:
xx + yy = 180
3yy + yy = 180
4yy = 180
yy = 45 acres
Now substitute with yy in equation II to get xx as follows:
xx = 3yy
xx = 3*45
xx = 135 acres
Based on the above calculations:
acres of corn = xx = 135 acres
acres of wheat = yy = 45 acres
