1 answer:
Travka [436]3 years ago

Answer: x = 13 and x = 4

Step-by-step explanation:

12)

(11x-15) + (5x - 13) = 180

we can collect like terms:

16x - 28 = 180

Then balance the equation to 16x = answer

add 28 to both sides

16x = 208

Then divide both sides by 16:

x = 13

14)

PQR = 82^o

And QS bisects (cuts in half) PQR, meaning that either side of QS is the same.

This means that PQS = 41^o and (10x + 1) = 41.

To balance this equation, we take away 1 from either side and then divide both sides by 10:

10x = 40

x = 4

This shows that x = 4.

Algebra is a universal language used in communicating ideas, and it therefore improves how people can teach or learn ideas from others

<h3>What is algebra?</h3>

Algebra is the mathematics representation of ideas, problems, situation or solutions using mathematical expressions.

Algebra makes use of numbers, variables, and operators to give value or convey information.

Algebra is therefore an indispensable communication tool that is used in all walks of life to improve understanding of disseminated information, from the original source, to the intended destination and beyond, without, losslessly losing any substance, value or understanding.

With algebra, a doctor speaking a foreign language in a remote location can perform complex and emergency operational procedures based on guidance from another doctor communicating through the internet to his exact location and a local robot that is able translate verbal information into action based on algebraic relationships.

Algebra allows the foreign doctor to obtain or look for specific health metrics and indicators.

It allows the foreign doctor to understand the cost implications as well as to avoid dangerous situations and risk factors which are best specified by algebraic relation, that is understandable to all languages, given that it is based on numbers and variables.

Algebra therefore is one of the main means through which one person can teach another or communicate ideas.

Step-by-step explanation:

They form a straight line  so the y sum to 180

52+58+q = 180

Combine like terms

110+q = 180

Subtract 110 from each side

q = 180-180

q = 70
