Answer:
26 students
Step-by-step explanation:
4% of 650 is 26
Part of it will be tomatoes so potatoes are 1/2 of the garden
All you do is just add 6.5+4.75 and then you get 11.25
Label your unknown numbers
I'm calling them x and y
x+y=21
5x+2y=66
find a relation of x and y
y=21-x
substitute this into your second equation
5x+2 (21-x)=66
simplify to find x
5x+42-2x=66
3x+42=66
3x=24
x=24/3=8
apply your findings to find the second number
8+y=21
y=13
check your answer
5 (8)+2 (13)=66
40+26=66
we now know that the first number x is 8
and the second number y is 13
Answer:
-3/2 x -1/2
Step-by-step explanation:
hello :
-1/2(-3x+6x+1)-3x =3/2 x-3x -1/2 = (3/2 - 3)x -1/2 =-3/2 x -1/2
