-183c +210

you have to distribute 1 to the parenthesis and then do the same with 13.

after you do that combine the like terms.

Determine the total number of cars

This is calculated by multiplying number of cars per floor by number of floors.

$Total = Floors*Cars$

$Total = 5 * 117$

$Total = 585$

Hence, there are 585 cars in total

The total cost of a shirt and a tie was $75.62. if the price of the shirt was $4.02 less than the tie, what was the price of the

kifflom [539]

--------------------------------------------
Define x:
--------------------------------------------
Let the tie be x
Tie = x
Shirt = x - 4.02

--------------------------------------------
Construct equation :
--------------------------------------------
The sum of the shirt and tie is $75.62
x + x -4.02 = 75.62
2x - 4.02 = 75.62
2x = 79.64
x = $39.82

--------------------------------------------
Find the cost of tie and shirt :
--------------------------------------------
Tie = x = $39.82
Shirt = x - $4.02 = $39.82 - $4.02 = $35.80

----------------------------------------------------------------------------------------
Answer: The price of the short is $35.80
----------------------------------------------------------------------------------------

Solve the equation for x. 1 3 (6x − 9) = −33

KIM [24]

Answer:

x = 1.07

Step-by-step explanation:

13 ( 6x - 9) = -33

78x - 117 = -33 ( opening brackets and multiplying )

78x = 84 ( - 117 taken to the other side makes it positive)

x = 84 / 78

x = 1.07
