The sales tax can be found through multiplying the total by the decimal form of the given sales tax (7.5=0.075). This operation yields 40.5 or $40.50. I really hope this helps!:)
Answer:
total = 96 sweets
Step-by-step explanation:
sweets shared in the ratio 4 : 5 : 7 = 4x : 5x : 7x ( x is a multiplier )
Seth got 18 more sweets than Frank , that is
7x = 4x + 18 ( subtract 4x from both sides )
3x = 18 ( divide both sides by 3 )
x = 6
Then
total = 4x + 5x + 7x = 16x = 16 × 6 = 96 sweets

➷ x + 1 = -10
- 1 from both sides to isolate x
x = -10 - 1
Solve:

I think it would most likely be 12 because you can divide 12 by 12.
Let's call Lyndale L and Jack J
L = J - 27
Jack has 80 fish so Lyndale has
L = 80 - 27
L = 53
Lyndale has 53 fishes.
