Answer: 133 children
Step-by-step explanation:
children = x
adults = y
2/9 (x+y) = y.....
7y - 2x = 0
y+95=x
7y - 2(y + 95) = 0
7y -2y -190 = 0
5y +190
y = 38
38+95 = x
x = 133 children
Answer:
The formula y = mx + b sometimes appears with
different symbols.
For example, instead of x, we could use the
letter C. Instead of y, we could use the letter F.
Then the equation becomes
F = mC + b.
All temperature scales are related by linear
equations. For example, the temperature in
degrees Fahrenheit is a linear function of degrees Celsius.
Water freezes at: 0°C, 32°F
Water Boils at: 100°C, 212°F
Hope this helps!
To find the mean, you add up all the numbers and divide by the number of numbers in the sequence
28+42+56+70+84+98+112
=490 divide by 7
=70
