4x+5x = 90
9x = 90
x = 10
10y + 10 + 5x = 180
10y + 10 +5(10) = 180
10y + 60 = 180
10y = 120
y = 12
answer
<span>d) x = 10, y = 12</span>
To compare 5/8 and 1/2, you will need to create fractions that have the same denominator. 1/2 is the same as 4/8.
5/8 is greater than 4/8, so she had knitted more than 1/2.
If you count the squares or units I got 12.
To find your answer you could type in the cost and multiply it by the tax rate, so $0.72 X $0.06(The tax rate )= $0.0432
You then subtract 0.0432 from 0.72 and get 0.6768
rounded it would be $0.68
Hope this is right..
