2)16.5

Step-by-step explanation:

step1:v/2.2 -0.1=7.4

step2:v/2.2=7.5

       multiply by 2.2 on both sides

step3:v=16.5

2) v/2.2 - 0.1 = 7.4

   v/2.2 = 7.4 + 0.1

   v /2.2 = 7.5

   v = 7.5 * 2.2

   v = 16.5


4) -1.3g + 1.9 = -11.1

    -1.3g = -11.1-1.9

    -1.3g = -13

     g = -13/-13

      g = 1


6) -14.3 = -1.4 -3d

   -14.3 + 1.4 = -3d

    -12.9 = -3d

    3d = 12.9

    d = 12.9/3

    d= 4.3

A flashlight costs $12.00. The sales tax is 6%. What is the amount of the sales tax?
oksano4ka [1.4K]
12.00x0.06, which is 0.72, so the sales tax is 72 cents. Basically, what you do to answer these kinds of questions is divide the percentage by 100 (6/100=0.06), because the percentage is out of 100%. Then you multiply that number by the price to get the sales tax. If you wanted to find the total price, add the tax you found to the original price ( in this case would give us $12.72 )

Hope this helps!

Please Help 6th Grade Math! Box Plots! 2 questions (Image attached)​
tangare [24]

Answer:

First answer is 14

Second answer is 25

Step-by-step explanation:

Median is the middle ( 1 2 3 4 5 the median would be 3)

You start at 2 and end at 27

List all the numbers from 2 to 27 and come from both ends until you get to the middle number(s)

In this case there are two 14 & 15

14+15=29 29÷2=14.5

Since there are no decimal answers you are left with 14

Range you take the two end numbers and subtract them (27 & 2)

27-2=25

Hopefully this helps!

A car is traveling at a rate of 120 kilometers per hour. What is the cars rate in miles per hour? How many miles will the car tr
Ymorist [56]

Answer:

150 miles

Step-by-step explanation:

speed = 120 km per hour

1 mile = 1.6 km

speed = 120 km per hr

divide 120 with 1.6 to get in miles=120/1.6

= 75 miles per hour

speed = 75 miles per hour

So, in 1 hr, it can travel 75 miles

the distance traveled by car in 2 hours = 75 * 2 = 150

Result : Speed = 75 miles per hour , distance = 150 miles

The answer will take the form: height smaller building = ? · height larger building, with ? = k. Already, you should be able to see that k must be less than 1. 15 feet = k (·) 90 feet; k =  15 /90  =  1/ 6   the height of the larger building.
