Answer:
1. 16
2. Ram=70 Raj=110
3. d+2, d+4, d+6
Step-by-step explanation:
1. p+2=6
p=6-2
p=4
5p-4=5(4)-4
=20-4
=16
2. Raj=40+Ram
Ram+Raj=180
Ram+40+Ram=180
Ram+Ram=180-40
2Ram=140
Ram=140/2
Ram=70
Raj=40+70
Raj=110
3. d, d+2, d+4, d+6.

Answer:
y = 4x + 5
Step-by-step explanation:
anything with the slope of 4x is parallel to the given equation. therefore, there are an infinite amount of answers.
<u>so, y = 4x + any number</u>
hope this helps!<3
There would be 12 people at the party!
In general, with n+1 people, the number of handshakes is the sum of the first n consecutive numbers: 1+2+3+ ... + n.
Since this sum is n(n+1)/2, we need to solve the equation n(n+1)/2 = 66.
This is the quadratic equation n2+ n -132 = 0. Solving for n, we obtain 11 as the answer and deduce that there were 12 people at the party.
Since 66 is a relatively small number, you can also solve this problem with a hand calculator. Add 1 + 2 = + 3 = +... etc. until the total is 66. The last number that you entered (11) is n.
Hope this helps!
