Answer: 21/35 girls 14/21 boys
Step-by-step explanation: To find the number of girls, multiply
3/5 × 35 = 21 girls
You can subtract 35-21 to find the number of boys, or multiply
2/5 × 35 = 14 boys
Realizing that 35/5 = 7, we can multiply
7/7 × 3/5 to get the <em>fractional equivalent of girls 21/35</em>
and 7/7 × 2/5 to get the <em>fractional equivalent of boys 14/35</em>
9514 1404 393
Answer:
True
Step-by-step explanation:
It is the sum of numbers having a common difference. The fact that it is a sum makes it a series (as opposed to a sequence, which is just a list of numbers). The common difference (of 2.5) makes it an arithmetic series.
True, the sum is an arithmetic series.
Answer:
2x - y = -10
Step-by-step explanation:
Standard form: x + y = n
y - 4 = 2x + 6
y = 2x + 6 + 4
y = 2x + 10
2x - y = -10
This sequence is not a geometric.
It is because, common ratio = 6/3 = 2
9/6 = 1.5
As the ratio's are not same, it is not a G.P
