Step-by-step explanation:
we know that
To get the 10% discount, a shopper must spend at least $200
so
Let
d ------> represent the spending (in dollars) of a shopper who gets the discount

I can't really help you with the math but I can give you the formulas for the answers.
1. You can subtract everything with the same “value” so that means you can subtract 3x from 6x, 5y - 5y and 39 - 27. This will give you: 3x + 0 = 12. Because 0 isn’t anything you get 3x = 12. Dividing everything by 3 you get x = 4
Hi
345 in standard form is : 3.45²
27 in standard form is : 2.7*10
I hope that's help !
Step-by-step answer:
1/8" long piece is not very much. However, mathematically,
we divide the total length by the length of each piece to get the number of pieces. So
4 2/5 / (1/8)
= (5*4+2)/5 * (8/1) [convert to fraction, and division to multiplication
= (22/5) * (8/1)
= 176/5
= 35 pieces with 1/5" left over.
