5x + 3y= 8.50
3x + 2y= 5.25
Lydia is the first equation. She bought 5 pounds of apples which is x and bought 3 pounds of bananas which is y. Basically, remember each banana and apple weighs a price per pound. We don't know the price so we just put an x. This is the same for the second equation
You reverse the inequality symbol if you divide or multiply by a negative number in order to solve the inequality.

Answer:
16 ft
Step-by-step explanation:
The equation is a^2+b^2=C^2
a= 30^2 = 900
b= we need to find
c= 34^2=1156
so the equation looks like this so far
900 + B^2 = 1156
we are going to subtract 900 so B^2 can be alone
1156 - 900 = 256
Now the equation looks like =
B^2 = 256
now we square root 256
which gives you 16
B = 16
