Mathematics

BaLLatris [955]3 years ago
3 0

Answer:

<em>21</em>

Step-by-step explanation:

<em>30-(3*3)</em>

<em>Follow the rule:</em>

<em>PEMDAS</em>

<em>parenthesis, exponents, multiplication, division, addition, subtraction.</em>

<em>Since we know that multiplication comes first before subtraction in PEMDAS, we do multiplication first. We can also put PARENTHESES around (3*3) because the multiplication comes first.</em>

<em>So:</em>

<em>30-(6)=</em>

Solve this system of equations
olga_2 [115]

Answer:

D) x = 4, y = -2, z = 3

Step-by-step explanation:

x = 3z − 5

2x + 2z = y + 16

2(3z - 5) + 2z = y + 16

6z - 10 + 2z = y + 16

8z = y + 26 ---> (A)

7x − 5z = 3y + 19

7(3z - 5) - 5z = 3y + 19

21z - 35 - 5z = 3y + 19

16z = 3y + 54 ---> (B)

8z = y + 26

16z = 3y + 54

2(y + 26) = 3y + 54

2y + 52 = 3y + 54

y = -2

8z = -2 + 26

8z = 24

z = 3

x = 3(3) - 5

x = 4

Translate the sentence into an equation.
4vir4ik [10]

The translation of the given sentence into an equation is: 7(b + 3) = 1.

<h3>How to Translate a Sentence into an Equation?</h3>

Variables can be used to represent an unknown quantity when translating statements into equation. The word "times" is represented as or means "×" (multiplication). "Sum" means addition as well.

Thus, the sentence given can be translated as shown below:

The unknown number is represented as variable b.

"The sum of a number (b) and 3" would be translated as: b + 3.

"Seven (7) times the sum of a number and 3 (b + 3)" would therefore be: 7(b + 3).

Therefore, translating the whole sentence into an equation, we would have:

7(b + 3) = 1.

Thus, the translation of the given sentence into an equation is: 7(b + 3) = 1.
