Answer: Simplified Equation (10x-10)

Answer if 3=x is 20

Step-by-step explanation:

the original side lengths are 3x and (2x-5) so multiply both those by 2.

Now you have 6x and 4x-10.

Now combine those and you have 10x-10.

Then plug in 3 for x

Last year 600 cars and 200 pickup were sold at a car lot . This year the number increased by 12%. In the same time period,the nu

Answer:the percent of increase of sales at the car lot is 6%

Step-by-step explanation:

Number of cars sold last year is 600.

Number of pickups sold last year is 200.

This year, the number of cars increased by 12%. This means that the amount by which the number of cars that was sold this year increased would be

12/100 × 600 = 0.12 × 600 = 72

Therefore, the number of cars sold this year would be

600 + 72 = 672

This year, the number of the pickups sold decreased 12%. This means that the amount by which the number of pickups that was sold this year decreased would be

12/100 × 200 = 0.12 × 200 = 24

Therefore, the number of pickups sold this year would be

200 - 24 = 176

The total number of vehicles sold last year is 200 + 600 = 800

The total number of vehicles sold this year is 672 + 176 = 848

The amount by which the sales increased would be 848 - 800 = 48

Therefore, the percent of increase of sales at the car lot would be

48/800 × 100 = 6%

The mass of a typical raindrop is 8.7 x 10^-5 grams. What is 8.7 x 10^-5 in standard form?
eimsori [14]
Hello There!

8.7 *  10^{-5} is in standard index form.
Standard form is when it is the original number
The '-5' as a power means you need to shift the zero back 5 spaces.
Or, divide by 100,000.
If you do this, you would get 0.000087.

Thus, making it option B.

Hope This Helps You!
Good Luck :)

Since both the expressions in x are equal to y then they are equal to each other, so

-2x + 3 = 13x - 4

-15x + 3 = -4

-15x = -7 

x = 7/15

and y = -2(7/15) + 3 =  31/15  = 2 1/15
