Answer:
$0.64
Step-by-step explanation:
Unit price is the cost of a single metre of ribbon
5.12/8=0.64
3x+1/10=x-1/7
subtract 1/10 from both sides
3x=-1/7-1/10+x
subtract x from both sides
2x=-1/7-1/10
add -1/7 and -1/0
1/7=10/70
1/10=7/70
-10/70-7/70=-17/70
2x=-17/70
divide by 2 ro multiply by 1/2
x=-17/140
Answer:
the correct answer is 1ft
Step-by-step explanation:
4ft-3ft
=1ft
we can easily solve this one by splitting theiddle term
x2 - 9x -10
x2 -10x + x - 10
x(x - 10) 1( x - 10)
(x + 1) (x-10)
x = -1 or 10
1. 10x4.5= 45
2. 103x3.67=378.01
