Today each cookie cost $0.75 less than the normal price. Right now if you buy 7 of them it will cost you $2.80. Write an equation to determine the normal price of each cookie.

Answers

Answer 1
Answer:

x-0.75=0.40 will determine the normal price of each cookie.

Step-by-step explanation:

Cost of 7 cookies = $2.80

Cost of one cookie = (2.80)/(7)\n

Cost of one cookie = $0.40

Let,

x be the normal price of cookie

As the price today is $0.75 less than normal price, therefore,

x-0.75=0.40

x-0.75=0.40 will determine the normal price of each cookie.

The circumference of the earth is approximately 131,000,000ft write this number in scientific notation and tell how you knew to use a positive or a negative exponent

Answers

U use a negative exponent to write a number smaller than 1, positive exponents are used to write numbers bigger than 1. clearly 131,000,000 is bigger than 1 so we use a postive exponent. there's always a decimal at the end of a whole number. and we move that decimal to the front where the fron value is more thnand one but less than 10. we move the decimal 8 places to the left and u get to 1.31X10^8
1.31 times 10 to the 8th power.
