8.12×10^5
... i got this by taking the first number 8 and then counting the places behind the 8 which would be 5 so than you move the decimal place by 5 so you get 8.12 then you show theirs 5 places behind the 8 by adding the 10^5 so youbget 8.12×10^5

Part A: Solve A = (x + 23) for x. (4 points) Part B: Determine the value of x when A = 108. (2 points) Part C: Solve -np - 90 &g
Galina-37 [17]
<span>Part A: Solve A = (x + 23) for x.

A = x + 23

=> A - 23 = x + 23 - 23

=> A - 23 = x

=> x = A - 23 <------- answer

Part B: Determine the value of x when A = 108

Replace the value of A in the expression x = A - 23

x = 108 - 23 = 75

x = 75 <------- answer

Part C: Solve -np - 90 > 30 for n.

-np - 90 > 30

=> -np + np - 90 >30 +  np

=> - 90 > 30 + np

=> -90 - 30 > 30 - 30 + np

=> -120 > np

=> np < - 120 <----- answer

Jesse buys a necklace that is on sale for 25% off the original price is 119.50 if tax is 7% what is the total price that Jesse w
trapecia [35]

Answer:

$95.89875

Step-by-step explanation:

The original price of the necklace is 119.5. And we are subtracting 25% from this. 119.5 - 25% = 119.5 - 1/4 since 25% is 25/100 which is also 1/4.

So without tax, the price of the necklace is 119.5 - 29.875 which is 89.625.

The tax is 7%. So we should add 89.625 to 7%. This is complicated, but it should result in 95.89875.

If we round this to the nearest cent, it should be <em>$95.9</em>.
