S= savings before she bought the dress s - $55 would be her new balance after she bought the dress.
We could also talk about her savings now (after her purchase). If we let n=now
n + $55 would be her balance before she bought the dress.
#7:
It means to solve for y.
#8:
We can write:
l = w + 2
Because it says the length is 2 more than the width.

Answer:The amount of paint that was sold altogether is 173.36 litres
Step-by-step explanation:
The total amount of paint that the paint shop stocks is 1800 litres.
24% of the paint is white. It means that the amount of white paint would be
24/100 × 1800 = 0.24 × 1800 = 432 litres.
The amount of the remaining paint other than white would be
1800 - 432 = 1368 litres
The shops sells 18% of the white paint. This means that the amount of white paint sold by the shop will be
18/100 × 432 = 0.18 × 432 = 77.6 litres.
The shops sells 7% of the rest of the paint.
This means that the amount of the rest paint sold by the shop will be
7/100 × 1368 = 0.07 × 1368 = 95.76 litres.
The amount of paint that was sold altogether would be
77.6 + 95.76 = 173.36 litres
Answer:
-17p+5
Step-by-step explanation:
Based on the given conditions, formulate: (--6p+1)+(4--11p)
Remove the parentheses: --6p+ 1 + 4-- 11p
Reorder and gather like terms:(--6p--11p)+( 1 + 4)
Collect coefficients for the like terms:(--6--11) x p +( 1 + 4)
Calculate the sum or difference:--17p+( 1 + 4)
Calculate the sum or difference:--17p + 5
