The answer is 50.2^2. You find the area of the outer circle and the middle circle. Then subtract the area of the smaller one from the larger one.
Percentage of cats


**cross multiply 12 and 100 which is 1200
**divide 35 into 1200
the answer is 34.3% when rounded

Answer:
£0.85 for each
£1.70 for both
Step-by-step explanation:
Variable x = cost of baked beans
2.30 + 2(2.60) + 2x = 10 - 0.80
Use PEMDAS
2.30 + 5.20 + 2x = 10 - 0.80
7.50 + 2x = 9.20
Subtract both sides by 7.50
2x = 1.70
Divide both sides by 2 to isolate the variable
x = 0.85
Let's check our work by plugging this into our original equation
2.30 + 2(2.60) + 2(0.85) = 10 - 0.80
2.30 + 5.20 + 1.70 = 10 - 0.80
7.50 + 1.70 = 9.20
9.20 = 9.20
Our number is correct
Answer:
The fourth number is 13
Step-by-step explanation:
7+9+11+13 = 40 it's the only one that works
2x+3y=6
- subtract 2x from both sides
3y = -2x + 6
- divide each term by 3

- simplify


- write in slope-intercept form
