Answer:

-3

Step-by-step explanation:

3x-5-6x-2= -1

-3x -7 = -1

-3x= 7-1

-3x= 6

x= 6/(-2)

x= -3

---------

proof:

3*(-2)- 5- 6*(-2)- 2= -1

-6 -5 +12 -2 = -1

-13+12= -1

-1= -1

done

Answer:

3(-1)-5-6(-1)-2. You found the value of X, so you need to put it back into the equation to see if it equals out.

how many meters are equal to 5,253 centimeters? use how the placement of the decimal point changes when dividing by power of 10

motikmotik

Answer:

$52.53\ \text{meters}$

Step-by-step explanation:

$1\ \text{meter}=100\ \text{centimeter}$

$1\ \text{centimeter}=\dfrac{1}{100}\ \text{meter}$

In the question the quantity that is required to be converted to meters is 5253 centimeters.

$5253\ \text{cm}=5253\times \dfrac{1}{100}\\ =52.53\ \text{meters}$

So, the required measurement in meters is $52.53\ \text{meters}$ .

there are 800 seats in the varsity theater. during regular preformances, all seats cost $12 each. It costs the owner $275 to pay

r-ruslan [8.4K]

Answer:

The correct answers are the following:

A) P=12n-275

B) 124

C) Decrease by $100

Step-by-step explanation:

A) P=12n-275  - Each person (n) pays $12, then the cost/expense ($275) is subtracted from the income to get the profit.

B) 1,213=12n-275 - Plug in the value for P ($1,213).

1,488=12n - Add $275 to both sides.

124=n - Divide both sides by $12.

n=124  - This the number (n) of people that attended.

C) P=12n-375 - Change the value for expense to $375.

P=12(124)-375 - Plug in the value for n (124).

P=1488-375 - Simplify and find the difference.

P=1,113 - This is your profit.

1,113-1,213=-100  - $100 reduction/decrease of profit (or -$100 to profit)

Hope this helps!

Solve the system by substitution. -8x - y = 30 -2y = x

masya89 [10]

Answer:

Solution: (-4, 2), x= -4 and y =2

Step-by-step explanation:

-8x - y = 30

-2y = x

Substitute for x

-8*(-2y) - y = 30

16y - y = 30

15y = 30

y = 30/15 = 2

Then x = -2y = -2*(2) = -4

Solution: (-4, 2), x= -4 and y =2
