Answer:
454
Step-by-step explanation:
set up a system of equation
let y be the number of students
let x be the number of adults
because there are twice the amount of students attended as adults, we can use y=2x as one equation
the other equation will be 6.5y+9x=4972 because this represents the total amount of money
plug 2x for y : 6.5(2x)+9x=4972 : x=226
plug 226 in for the first equation : y=2(226) : y=452
Answer:
Step-by-step explanation:
Given: P is Three-fifths the length of the line segment from K to J
To find: x- and y-coordinates of point P on the directed line segment from K to J
Solution:
Section formula:
Let point K and J be 
such that the point 
divides KJ in ratio 
Then coordinates of point P are given by 
Take 
So,
coordinates of point P = 
Answer:
8x+5
Step-by-step explanation:
To solve this, you need to combine the like terms. The line terms are 3x +5x and -2+7. 3x+5x=8x and 7-2 (same thing as -2+7) is positive 5 so its 8x+5
