We move all terms to the left:

9(2x+15)-(45)=0

We multiply parentheses

18x+135-45=0

We add all the numbers together, and all the variables

18x+90=0

We move all terms containing x to the left, all other terms to the right

18x=-90

x=-90/18

x=-5

Answer:

-5

Step-by-step explanation:

  • 9(2x+15)=45
  • 18x+135=45
  • 18x=45-135
  • 18x=-90
  • x=-90/18
  • x=-5

The length of a rectangle is 4 less than three times its width. The perimeter is 72 feet. What are the dimensions of the rectang
Liono4ka [1.6K]
Say width equals x.
Length = 3x - 4
Solve for x: 72 = 2(3x - 4) + 2x
72=6x-8+2x
80=8x
X=10
So width = 10
Length= 3(10) - 4 = 26

What is the constant of proportionality between y/x
Y_Kistochka [10]

Answer:

3.5

Step-by-step explanation:

To find the constant of proportionality between y/x you investigate the trend in values of x with corresponding values of y

For this case, when x =1, y=3.5

                       when x=2, y=7

                       

Taking in case 1, y/x = 3.5/1 = 3.5

In case 2, y/x= 7/2 = 3.5

But you know that the constant of proportionality k is given by;

y=kx------------------------making k subject of formula

y/x=k

Hence in this case, your constant of proportionality is 3.5

the contractor demands a working temperature of 82 degrees Fahrenheit. what is the equivalent temperature in degrees Celsius
stiks02 [169]

Answer:

27.8 Celsius

Step-by-step explanation:

The equation to convert Fahrenheit and Celsius is:

F = (9/5)C + 32

82 = (9/5)C + 32 -- subtract 32 from both sides

50 = (9/5)C -- multiply both sides by 5

250 = 9C -- divide by 9

27.777 = C

round up to 27.8 C

The numbers Of students in the four sixth-grade classes at Northside School are 26,19,,34,and 21.Use the properties to find the
Dafna11 [192]
Basically there are 3 addition properties and they are associative property, identity property, and commutative property.

Commutative property is just changing the order of the addends. Example: 26+19+34+21= 21+34+19+26

Identity Property is just adding a 0 to the number that doesnt change anything. Example: 26+19+34+21 +0 = 100

Associative property is just changing the grouping of the addends. Example: (26+19) + (34+21)

I know these properties may be complicated i know inhate them too haha but i hope i helped :) if you want you can search up the distributive property too but its with multiplication and addition combined and its harder but i think these are the 3 main properties.
