Answer:

x=1

Step-by-step explanation: 9x+7=16

Subtract 7 from both sides.

9x=16−7

Subtract 7 from 16 to get 9.

9x=9

Divide both sides by 9.

​Divide 9 by 9 to get 1.

Answer:

34

Step-by-step explanation:

9x+7 when x=3

Plug 3 into the equation for the variable x

So, it would be 9(3)+7

Multiply 9×3 together to get 27

Finally, add 27 and 7 together

The answer should be 34

Answer: 180 times

Step-by-step explanation:

Given the following :

Production capacity of old workshop :22,912,546,992 toys per year

Production capacity of new workshop:

4,134,232,638,937 toys

Approximately how many times as many toys can the new workshop produce each year compared to the old workshop?

Production capacity of new workshop / production capacity of old workshop

= 4,134,232,638,937 / 22,912,546,992

= 180.435

= 180 ( nearest whole number)

<1 and <2 form a linear pair. The measure of <2 is six more than twice the measure of <1. Find the measure of <2
MrMuchimi

Answer:

122 Degrees

Step-by-step explanation:

Since we are given that angle 1 and 2 make a linear pair:

angle 1 + angle 2 = 180 degrees ----------------------------(1)

We have also been told that angle 2 is 6 more than twice the measure of angle 1

Which means: angle 2 = (2*angle1)  + 6 -------------------(2)

From putting the value of angle 2 in (1) from (2)

<em>angle 1 + 2*angle 1 + 6 = 180</em>

<em>3*angle 1 = 174</em>

angle 1 = 58 degrees -----------------------(3)

From (1) and (3):

<em>angle 2 + 58 = 180</em>

angle 2  = 122 degrees

Therefore, the measure of angle 2 is 122 degrees

1. Annual percent increase in rent is basically just a percentage of the rent increased each year.

2. Heater: Use fire places, or lower the amount of air conditioning usage so it's not so cold.

Electricity: Turn off ceiling fans and lights when not used, or only allow the essential things to use electricity.

Water: Not leave faucets or showers running, or no bathtubs which prevents baths.

3. The couple could save $450 in one year because 3000 divided by 0.15 which is the 15%, equals to the total amount saved at $450.

4. Groceries/everyday essentials, Gas money, taxes, pay off loans.
