X=amount of money woman has
n=pounds of sugar
Store #1: 8.5*n=x+30
Store #2: 8*n=x-25
multiply #2 by 17/16 to make coefficient of n same as in #1
2: 8.5*n=17/16(x-25)
Subtract #2 from #1
0=x+30-17/16(x-25)
x+30-17x/16 +25*17/16
x/16=30+25*17/16
x=480+425
=905 cents
=$9.05
Answer:
Step-by-step explanation:
All triangle must have angle values adding up to 180 degrees.First solve for y;
110+33+y=180
y=37 degrees
x is the opposite inverse angle of 33 degrees, it has an angle measure of 33 degrees.
z is equal to 110 degrees because it is opposite to that angle measure because all rhombi have 2 way symmetry.
Just do 198 divide by 33. The answer is how much gas will be used.
