I'm not sure which formula to use because it's not indicated, but I'll just solve for x in both equations.

3x + 7 = 19

First I would subtract 7 on both sides:

3x = 12

Then I would divide 3 on both sides:

x = 4

x - 1 = 5

I would just add 1 on both sides:

x = 6

Hope I helped :)

CAN SOMEONE HELP ME ASAP
BARSIC [14]

Answer:

3 minutes

Step-by-step explanation:

To calculate this, you have to multiply 4.5 minutes by 8. This will give you the amount of pages that Wafa will print.

4.5 x 8 = 36 pages

Now that you have the amount of pages, you should divide it by the speed of the Sure-Fire printer. 12 ppm means that 12 pages can be printed in 1 minute.

36/12 = 3

Therefore, it would take 3 minutes if Wafa were to use her brother's Sure-Fire printer.

You are asked to tutor a friend in algebra with adding and subtracting trinomials. Create an example of how to add two trinomial
vesna_86 [32]
Addign trinomials (2x+4xy+8z)+(8x+5xy+23z) all you have to do is combine the like terms 2x and 8x= 10x, 4xy+5xy=9xy, and 8z+23z=31z. so the simplified answer to adding the trinomials would be 10x+9xy+31z. 

Subtacting trinomials (4x+9y+3) - (-1+3x-2y) . 
When doing subtracting you still combine like terms but this time you change the sign before every term. If that is confusing, just pretend there is a negative 1 infront of parenthases and multiply that before you subtracts the two trinomials. so...
4x - 3x= x, 9y+2y=11y and 3+1=4. so simplified answer of the subtraction would be x+11y+4 

I hope this helped :) Good luck !

6.5. Does Spending Measure Welfare? Suppose a community spends $1 million on salaries and equipment for its police department. B
marta [7]

Answer:

(a) Measured GDP will decrease by $200,0000

(b) No

Step-by-step explanation:

(a) Gross Domestic Product (GDP) is the total value in monetary terms of al the goods produced in a geographic location.

There will be a $200,000 decrease in the value of the GDP of the community as a result of reduction in the community spending from $1 million to $800,000.

(b) Generally, GDP is not a true indicator of welfare, likewise in this case, GDP does not reflect the welfare of the community.

There's a decrease in the community spending from $1 million to $800,000 but there's an increase in the welfare of the community as a result of decrease in crime rate.

777dan777 [17]

<em>48.984 meters</em>

Step-by-step explanation:

The distance around a circle is called the circumference, the formula for the circumference is...

C=\pi d

OR

C=2\pi r

Since we have the diameter we will be using the first one.

C=3.14*15.6

C =

<u>48.984 meters</u>.
