There's an infinite number of solutions. here's a few.
1+-9=-8
2+-10=-8
3+-11=-8
4+-12=-8
5+-13=-8
6+-14=-8
Answer: 1. 63; 2. 84; 3. 104 4. 1:2
Step-by-step explanation: Since Zoey has $28, and the ratio is 4:5, we can multiply the ratio by 7 on both sides so that it is 28:35, giving $35 for andrew, and this $28+$35=$63. Since the ratio of red to white marbles has a sum of 10, but there are 120, we multiply the ratio by 120/10=12, to make the ratio applicable to the scenario, so 7 times 12 = 84 red marbles. Same way for the theater question, 195/15=13, so 8 times 13= 104, and so 104 people are boys. For the last question you can simply divide both sides by 5 (or think of it as a fraction, 5/10=1/2).
√196s² = √196 times √s²
s² is the square of 's'
196 is the square of 14
So both can easily come out of the radical.
√196s² = <u>14s</u>
Answer:
Yes, the ratios do form a proportion.
