Answer:
Multiply both sides by
Step-by-step explanation:
Given
Required
Get an equivalent of
To do this, we simply multiply through by
N + (n+1) + (n+2) + (n+3) = 90
if n is the first number, then the next number is 1 more than n, the next number is 2 more than n, etc.
Simplify the above expression:
4n + 6 = 90
4n = 84
n = 21
n+1= 22
n+2 = 23
n+3 = 24
4: 1 because you could divide both sides of the ratio by 25
<span>Since there were 2100 people on saturday and 4900, lets do the math..
#1) Line up the numbers, when it comes to adding it doesn't really matter which goes on the top.
#2) Add or use a calculator for help.
#2b 4900-2100=2800
Thats all!
Hope this help!

Answer:
a) -2
b) 1/2
Step-by-step explanation:
2x + y = 15 Subtract 2x from both sides
y = -2x + 15 The slope is -2
Parallel lines have the same slope.
Perpendicular lines have negative inverse slopes.
-2 flips to 1/2
