Answer:in first part of equation add 10x and 3x (like terms)

13x-4.5=12x-1.1

move all terms containing x to left side of equation

13x-4.5-12x= -1.1

x-4.5= -1.1

Subtract 4.5 from both sides

x=3.4

madam [21]

Answer:

14

Step-by-step explanation:

I first multiplied 490 by 3/7

giving me 1470/7

I divide 1470 by 7 giving me 210

As I got 210

I multiplied 210 with 2 and got 410/3

I divided 410 by 3, getting 140.

It then said half of what was delivered was put into 5 pound bags, so

140× 1/2 or 140÷2 is 70

70 divided by 5 is 14

They made 14 5-pound bags.

rewona [7]

Answer:

2,4, and 8.

Find the slope of the line passing through the points (9, 1) and (-3, -3). Describe the slope as positive, negative, zero, or un
GarryVolchara [31]

Answer:

<h3>Given points:-</h3>
  • (9,1)
  • (-3,-3)

We have to find slope =m

  • As we know that

{\boxed{\sf Slope_{(m)}=\dfrac {y _2-y_1}{x_2-x_1}}}

  • Substitute the values

\qquad {:}\longrightarrow\sf m=\dfrac {(-3-1)}{(-3-9)}

\qquad {:}\longrightarrow\sf m=\dfrac {-4}{-12}

\qquad {:}\longrightarrow\sf m={\dfrac {1}{3}}

\therefore\sf Slope\;of\;the\:line=\dfrac {1}{3}(undefined)
