1. Distribute the 4 with (2x-5)
2. Then add 15 to -20
3. Isolate x by adding 5 to the other side of the equal sign
4. Finally divide by 8 on both sides

I'm assuming that your solving for x...

4(2x-5)+15=11
First you want to distribute the 4 into the parenthesis.
4*2x   4*-5
8x       -20
8x-20+15=11
Next combine like terms.
-20+15
-5
8x-5=11
Next step would be getting the x alone so add five to both sides.
8x-5=11
    +5  +5
8x=16
Finally, furthering the previous step, you divide each side by 8.
8x=16
/8    /8
x=2

An air traffic controller is tracking two planes. To start, Plane A is at an altitude of 3427 feet and Plane B is at an altitude
jeyben [28]
3427 + 65.75s = 5000 + 35.5s
65.75s - 35.5s = 5000 - 3427
30.25s = 1573
s = 1573 / 30.25
s = 52 seconds <== they are the same at 52 seconds

3427 + 65.75(52) = 6846
5000 + 35.5(52) = 6846

and their altitude is 6846 <===

The next model of a sports car will cost 4.4% more that the current model. The current model costs $48,000, How much will the pr
podryga [215]

Answer:

$50,112.  Increase is $2,112

Step-by-step explanation:

1st way.  $48,000 x 1.044 = $50,112.  1.044 is the same thing as saying 104.4% of the total price in decimal form, which is what the new price would be when adding 4.4% to the 100% of the original price.  To get the amount of increase just find the difference in the two.  $50,112-$48,000 = $2,112

2nd way.  $48,000 x .044.  =  $2,112 .044 is 4.4% in decimal form. So you found the increase here.  Add the increase to the original price.  $48,000 + $2,112 to get the new price of $50,112.
