When Paolo tried to simplify 5 - 7 at Step 2, instead of keeping the sign of the answer, -2, he added it. He really should have written 3 - 2.
Subtract 6g from both sides.
-3g = -7
Divide both sites with 3.
-g = -7/3
Multiply both sides with -1
g = 7/3
This is a pythagorean theorem problem therefore a^2+b^2=c^2
a=8, b=?, c=10
8^2+b^2=10^2
64+b^2=100
100-64=56
square root of b^2=square root of 56
b=2 rad14
2 rad14 +4=
2 (rad14 + 1)= ANSWER
Step-by-step explanation:
7x+5y=25 ×3 7×-1.5+5y=25
5x+3y= -23 ×5 -10.5 +5y =25
5y= 25 + 10.5
21x+15y=75 5y= 35.5
25x+15y=69 y= 7.1
-4x=6
x=-1.5
