Answer: 2p - 2q

Step-by-step explanation:

(3p-10q)-(p-8q) is simply an algebraic expression.

To solve it, you first open the brackets

i.e 3p - 10q - p + 8q (the minus sign between the brackets have multiplied the next minus sign, so it becomes plus sign)

Now, collect the like terms of i.e common terms

= 3p - 10q - p + 8q

= 3p - p - 10q + 8q

= 2p - 2q

Thus, the final expression is 2p - 2q since it cannot be further simplified.

Solve the x 1/3x + 5> 10

kotykmax [81]

Answer:

The solution to the inequality is:

$\frac{1}{3}x+5>10\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x>15\:\\ \:\mathrm{Interval\:Notation:}&\:\left(15,\:\infty \:\right)\end{bmatrix}$

The solution graph is also attached below.

Step-by-step explanation:

Given

We are given the expression

$\frac{1}{3}x+5>10$

To determine

Solve for x

Given the expression

$\frac{1}{3}x+5>10$

Subtract 5 from both sides

$\frac{1}{3}x+5-5>10-5$

Simplify

$\frac{1}{3}x>5$

Multiply both sides by 3

$3\cdot \frac{1}{3}x>5\cdot \:3$

Simplify

$x>15$

Thus, we conclude that:

$x>15$

Therefore, the solution to the inequality is:

$\frac{1}{3}x+5>10\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x>15\:\\ \:\mathrm{Interval\:Notation:}&\:\left(15,\:\infty \:\right)\end{bmatrix}$
