Answer: number of adults = 3, number of children = 5
Step-by-step explanation:
let the number of adults be x, and the number of children be y.
x + y = 8 , 15x + 8y = 85
1st equation x 8 = 8x + 8y = 64
substitute x=3
Slope intercept form is to leave y by itself. ok this is the initial question 3x+4y=5 and we want y by itself. first subtract 3x by both sides. you now have 4y=5-3x, then divide 4 by both sides. y=5-3x/4, this is slope intercept form, if you still need help download the app socratic and photomath.
4 of a 10 because there is 4 blue marbles and 6 yellow
Answer:
38
Step-by-step explanation:
Let SUV be a triangle
Perimeter of SUV = SU+SV + UV
102 = 38 + 26 + UV
102 = 64 + UV
UV = 102 - 64
UV = 38
Hence the length of UV is 38
solution:
= $15 for 3 packages
= 5 packages per dollar (15/3)
