Answer:

x + 14 = 5x - 74

x - 5x = -4x

-74 - 14 = -88

-4x = -88

-4x/4 = -88/-4

x = 22

Step-by-step explanation:

The steps above are how you would evaluate a problem like that!

Mathematics includes the study of such topics as quantity, structure, space, and change. It has no generally accepted definition. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof.

Step-by-step explanation:

Mathematics is the study of numbers, shapes and patterns. The word comes from the Greek word "μάθημα" (máthema), meaning "science, knowledge, or learning", and is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada). ... Numbers: how things can be counted.

Therefore, Mathematics is the abstract study of topics such as quantity (numbers), structure, space, and change!

Given that f(x) = x^2 + 4x, evaluate f(-2)

atroni [7]

Hi there!

To find f(-2), we need to plug in the value x = -2 into the equation.

$f( - 2) = ( - 2) {}^{2} + 4 \times - 2 = 4 - 8 = - 4$
Remember that multiplying a negative by a positive ends up with a positive.

sam had 70 erasers and rulers. after giving away 1/3 of his erasers and 10 rulers, he had an equal number of erasers and rulers

Radda [10]

Answer:

36 erasers

Step-by-step explanation:

Let number of erasers be e

let number of rulers be r

We can write:

e + r = 70

and

After giving away, he has

Erasers: 2/3e

Rulers: r - 10

These two are equal, so we can write and solve:

2/3e = r - 10

2/3e + 10 = r

Putting this in initial equation, we have:

e + (2/3e + 10) = 70

5/3e + 10 = 70

5/3 e = 60

e = 36

And rulers is:

r = 2/3(36) + 10 = 34

Hence, he had 36 erasers in the beginning
