So, let's set this up:
0.04x+0.05y=1100
0.05x+0.04y=1150
Let's multiply each equation by 100:
4x+5y=110000
5x+4y=115000
Now let's add those together:
9x+9y=225000
And we need to find x+y, so we just divide by 9 and get 25,000
Area of the circle is 78.5 sq. units.
<u>Step-by-step explanation:</u>
Circumference of the circle = 31.4 units
2 π r = 31.4 units
2 × 3.14 ×r = 31. 4 units
r = 31.4 / (2×3.14)
= 5 units.
Area of the circle = π r² = 3.14 × 5 × 5 = 78.5 sq. units.

Answer:
y = 27
Step-by-step explanation:
line segment BA and CD are congruent, turn them into an equation
3y - 59 = y - 5
subtract 1y from both sides, you get 2y - 59 = -5
then, add 59 to both sides and the equation is now 2y = 54
divide each side by 2 and you get the value of y (y = 27)
