Answer:
145 degrees
Step-by-step explanation:
1. A straight line is 180 degrees
2. 180-35=145
Answer:
2.89
Step-by-step explanation:
Note the equal sign, what you do to one side of the equation, you do to the other. To solve, do the opposite of PEMDAS. Isolate the variable, z.
First, subtract 12 from both sides:
25 = 4.5z + 12
25 (-12) = 4.5z + 12 (-12)
25 - 12 = 4.5z
13 = 4.5z
Isolate the variable, z. Divide 4.5 from both sides:
(13)/4.5 = (4.5z)/4.5
z = 13/4.5
z = ~2.89 (rounded).
2.89 is your answer.

❖ 8² - (4+2)² × 2 ÷ 4 = 46
Follow order of operations:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
(Note: Multiplication and division can be done in either order as well as addition and subtraction.)
First, do parenthesis and exponents:
(4 + 2)² = 36 8² = 64
Now do multiplication and division:
36 x 2 ÷ 4 = 18
Now do subtraction:
64 - 18 = 46

Usando proporciones, en conjunto con multiplicación cruzada, encontra-se que el valor de p es de 6.
<h3>¿Qué es una proporción?</h3>
Una proporción es una fracción de la cantidad total, e puede ser encontrada aplicando una regla de três.
En este problema, relación es dada por:
Aplicando multiplicación cruzada:
8p = 6(p + 2)
8p = 6p + 12
2p = 12
p = 12/2
p = 6.
