This is false because 20-8 is 12 and 12 times 5 isnt 17

Using the order of operations I found out that the answer is 60 which isn't 17 so the answer is false.

LOTS OF POINTS!!!!!!!!<br><br>Please help asap!!!!! I need to solve for x
lozanna [386]

Answer:

x = 1 11/15

Step-by-step explanation:

Using ratios of similar triangles

3            5.2

-------- = ----------

4            (5.2 + x)

Using cross products

3 * (5.2 + x) = 5.2 * 4

Distribute

15.6 + 3x = 20.8

Subtract 15.6 from each side

15.6-15.6 + 3x = 20.8 -15.6

3x =5.2

Divide each side by 3

3x/3 = 5.2/3

x = 5.2/3

x=52/30

x = 26/15

x = 1 11/15

A line passes through the points (9,6) and (6,5). What is its equation in slope-intercept form?
Tju [1.3M]

Answer:

Y=X/3+3

Step-by-step explanation:

M= Y2-Y1/X2-X1

  = 5-6/6-9

  = -1/-3

  = 1/3

sub x=6, y=5, M=1/3 into Y=MX+C

5=6/3+C

5=2+C

5-2= 2+C-2

3=C

To add expressions, you should take note that you can only combine same terms which means they have the same degree of exponents.

-5x^4 + 6x^3 – 43 + 6x^5 – x^2 + 12x + 12

In this expression, you can only combine the constants because they are the only similar terms:

-5x^4 + 6x^3 + 6x^5 – x^2 + 12x + 12 – 43

-5x^4 + 6x^3 + 6x^5 – x^2 + 12x – 31

The standard form starts with the term with the highest exponent so you just have to arrange the terms:

6x^5 - 5x^4 + 6x^3 – x^2 + 12x + 12

1. 2 (x-3) = 9+ 3 (x-9)
bazaltina [42]

Answer:

x = 12

Step-by-step explanation:

Given

2(x - 3) = 9 + 3(x - 9) ← distribute parenthesis on both sides

2x - 6 = 9 + 3x - 27, that is

2x - 6 = 3x - 18 ( subtract 3x from both sides )

- x - 6 = - 18 ( add 6 to both sides )

- x = - 12 ( multiply both sides by - 1 ), thus

x = 12
