PLEASE HELP !!!

1 answer:

Answer:

final cost of 3 pounds: <u>  8 dollars  </u>

final cost of p pounds: <u>   3.75p - 3.25  dollars  </u>

Step-by-step explanation:

Each pound costs $3.75, so 3 pounds cost 3*3.75 = 11.25 dollars. Subtract off the $3.25 to get the final cost to be 11.25-3.25 = 8 dollars. This takes care of the first part.

For the second part, the expression for the final cost is 3.75p - 3.25; where the 3.75p is the cost before the coupon is applied. If you plugged p = 3 into that expression, you should get 8 as a result. The variable p is some positive whole number. It's a place holder for the number of pounds of apples.

please help :) Which number is less than 2.167 × 10 to the 4 power? A. 9,978 B. 1.1 x 10 to the 6 power C. 56,344,000 D. 2.468 ×
zheka24 [161]

Answer: A

Step-by-step explanation

2.167x10^4 = 21,670

                   = 9,978

1.1x10^6      = 1100,000

                   = 56,344,000

2.468x10^5 =  246,800

½x - 5 = -6<br><br> Which solution makes this equation true?<br><br><br> 1. -12<br><br> 2. -2
Ugo [173]
Answer: -2

Let’s try x = -12

1/2(-12) - 5 = -6

PEMDAS says to multiply first

1/2 x -12 = -6

So

-6 - 5 = -6

-6 - 5 = -11 not -6 so it’s not that

Now let’s do x = -2

1/2(-2) - 5 = -6

Again, you multiply first

1/2 x -2 = -1

-1 - 5 = -6 so it works

I am a product. one of my fiactors is 7. the sum of my factors equals 11. what number am i?
adell [148]
The asnwer is 28. Since 7 is one of the factors,and 7+x=11,you would do 11-7 to find x. After doing 11-7 to find x (4),then you multiply 7 and 4 since they are the factors of the missing number. 7×4 is 28,therefore,you are the number 28.
