The ratio 90: 105 is not equivalent to 15: 18
I think its 14 because 46-4=42 and 42/3 is 14
Simplifying
-2x + -4y = 9
Solving
-2x + -4y = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4y' to each side of the equation.
-2x + -4y + 4y = 9 + 4y
Combine like terms: -4y + 4y = 0
-2x + 0 = 9 + 4y
-2x = 9 + 4y
Divide each side by '-2'.
x = -4.5 + -2y
Simplifying x = -4.5 + -2y<span>13/18
169

T= total cost= $3.30
c= cost of fruit per pound
x= # of pounds of fruit purchased
EQUATION
T= (c)(x) - $0.55 coupon
to find c, substitute $3.30 total for T
$3.30= cx - $0.55
add $0.55 to both sides
$3.85= cx
divide both sides by x
$3.85/x= c
Hope this helps! :)
Answer:
91.68
Step-by-step explanation:
first u find the perimeter of the inner shape...
15+15+12+12=54
than u find the circumstances of the two circles than dividing it is half since it is half a circle
c=2×pi×r
c=2×3.14×6
c=37.68
than add them together
37.68+54= 91.68
