Let x be the total money she had
So x-45.32=32.25
□ x =45.32+32.25
1. x-2(2x-3.5)=-14
x-4x+7=-14
-3x=-21
x=7
2. y=2(7)-3.5
y=14-3.5
y=10.5
hope this helps!
Pi is actually one of the letters of the Greek alphabet, but it is most known in the math field as the ratio between the circumference of a circle and the circle's diameter.
There is no exact measure of pi, as it does not terminate but it starts like:
3.14159265
Answer:
for the radius, the cloest i could get was 6.77. therefore the diametre would be double meaning its would be 13.54
so sorry if this is incorrect!
Y=2/3x-1 is the equation:)
