Answer:

<h3>\boxed{ \boxed{ \bold{ \sf{3}}}}</h3>

Step-by-step explanation:

\sf{x + 3(2x - 5) = 6}

Distribute 3 through the parentheses

⇒\sf{x + 6x - 15 = 6}

Collect like terms

⇒\sf{7x  - 15 = 6}

Move constant to right hand side and change it's sign

⇒\sf{7x = 6 + 15}

Add the numbers

⇒\sf{7x = 21}

Divide both sides of the equation by 7

⇒\sf{ \frac{7x}{7}  =  \frac{21}{7} }

Calculate

⇒\sf{x = 3}

Hope I helped!

Best regards!

<h2>x = 3</h2>

Step-by-step explanation:

x + 3(2x - 5) = 6 \\ x + 6x - 15 = 6 \\ 7x = 6 + 15 \\ 7x = 21

\frac{7x}{7}  =  \frac{21}{7}  \\ x = 3

Step 1 Use 3 to open the bracket

Step 2: Collect like terms and simplify

Step 3: Divide both sides by 7

A six-sided die is rolled find P (of an even number) don't forget to reduce fraction
velikii [3]

Answer:

P(even no.) = 0.5

Step-by-step explanation:

Using the Formula of Probability = \frac{Required  outcomes}{Total possible outcomes}

Total no. of outcomes when a six sided die is rolled are: 6 (as shown below)

1, 2, 3, 4, 5, 6

Required outcomes are only even number: 3 (as shown below)

2, 4, 6


Thus P(even no.) = \frac{3}{6} = \frac{1}{2} = 0.5

Select all ordered pairs that satisfy the function y = 4x + 3
qwelly [4]

Answer:

see explanation

Step-by-step explanation:

To determine which ordered pairs satisfy the equation substitute the x coordinate of the point into the right side and if the value obtained equals the y coordinate of the point then it satisfies the equation

(- 1, - 1)

x = - 1 : y = - 4 + 3 = - 1 ⇒ (- 1, - 1) satisfies the equation

(2, 11)

x = 2 : y = 8 + 3 = 11 ⇒ (2, 11) satisfies the equation

(4, 7)

x = 4 : y = 16 + 3 = 19 ≠ 7 ⇒ (4, 7) does not satisfy the equation

(7, 1)

x = 7 : y = 28 + 3 = 31 ≠ 1 ⇒ (7, 1) does not satisfy the equation
