Answer:
Step-by-step explanation:
4.
1/3(6x-5)-x=1/3-2(x+1)
multiply by 3
6x-5-3x=1-6(x+1)
3x-5=1-6x-6
3x+6x=-5+5
9x=0
x=0
1.
5x-2(2x-1)=6
5x-4x+2=6
x=6-2=4
x=4
2.
let the numbers be x,x+1,x+2
x+x+1+x+2=90
3x+3=90
3x=90-3
3x=87
x=87/3=29
so numbers are 29,29+1,29+2
or 29,30,31
let th price of bacon=x per pound
price of hot dog=x-1.50 per pound
4(x-1.50)+2x=30
4x-6+2x=30
6x=30+6
6x=36
x=36/6=6
cost of bacon=$ 6 per pound
cost of hot dog=6-1.50=4.50 $
combined cost of 1 pound of each=6+4.50=$10.50
so C
