Answer:

A and B

Step-by-step explanation:

Given

3x + 3(x + y) ← factor out 3 from each term

= 3(x + x + y) → B

3x + 3(x + y) ← distribute the parenthesis

= 3x + 3x + 3y ← collect like terms

= 6x + 3y → A

Sole for y k = p/2(y+w) y =

mojhsa [17]

Answer:

Answer: y = (2k -pw)/p

Step-by-step explanation:

$k = \frac{p}{2} (y + w)$

multiply 2 on both sides:

$k \times 2 = 2 \times \frac{p}{2} (y + w) \\ \\ 2k = p(y + w)$

open the bracket:

$2k = py + pw$

subtract pw from both sides:

$2k - pw = (py + pw) - pw \\ 2k - pw = py$

divide p on both sides:

$\frac{2k - pw}{p} = \frac{py}{p} \\ \\ y = \frac{2k - pw}{p}$

What is the solution to the opening sentence?

777dan777 [17]

Hello.

The answewr is: 3

Step 1: Subtract 2x from both sides.

4x−4−2x=2x+2−2x

2x−4=2

Step 2: Add 4 to both sides.

2x−4+4=2+4

2x=6

Step 3: Divide both sides by 2.

2x2=6/2

MissTica

Answer:

$T > 45$

Step-by-step explanation:

Given

$\frac{T}{3} > 15$

Required

Graph the solution

$\frac{T}{3} > 15$

Multiply both sides by 3

$3 * \frac{T}{3} > 15*3$

$T > 15*3$

$T > 45$

See attachment for graph (Assume T is on the x-axis)
