Step-by-step explanation:
(a) Add the parts of the ratio, 1 + 3 = 4 parts
Divide 260 by 4 to find the value of one part of the ratio.
260 ÷ 4 = 65 ← value of 1 part of the ratio, thus
3 parts = 3 × 65 = 195
260 in the ratio 1 : 3 = 65 : 195
(b)
Given
3 : 5 ← divide both parts of the ratio by 3
: 
= 1 : → A

Step-by-step explanation:
4 3/4 - 2 2/3 = ?
When adding or subtracting fractions, the denominators must be the same. We need to find a common denominator for the fractional portions of each mixed number. In other words, we are looking for equivalent fractions for 3/4 and 2/3. By listing the multiples of 4 and 3, we see that 12 is common to both numbers do we can use 12 as our common denominator.
4, 8, 12, 16, 20...
3, 6, 9, 12, 15....
4 3/4 If we multiply the numerator and denominator by 3, our equivalent fraction is 4 9/12.
2 2/3 If we multiply the numerator and denominator by 4, our equivalent fraction is 2 8/12.
Now we can subtract
4 9/12 - 2 8/12 = 2 1/12.
So Cameron needs an additional 2 1/12 cups of flour.
Answer:
x<3
Step-by-step explanation:
The sum is 1625.
Answer in Words: One thousand and six hundred twenty-five.
The cube of 10 is 1000.
10 X 10 = 100 (square of ten)
100 x 10 = 1000 (cube of ten)
The square of 25 is 625.
25 x 25 = 625 (square of 25)
Therefore, 1000 + 625 = 1625
the sum is 1625
Y = x + 2 is closest to what I believe is the solution.
If the club begins with 2 members, then +2 MUST appear in the formula.
If the club adds 2 members every week, then the total number of members would be
f(x) = y = 2 + 2(x-1), where x is the number of weeks.
Test this: If x = 1, then y = 2+2(1-1) = 2 + 0 = 2. This is correct. The club began with 2 members in week 1
