If the first step in the solution of the equation 2x - 8 = 5x + 3 is "subtract 2x," then what should the next step be?

subtract 5x
add 8
subtract 3

Answers

Answer:

You would not subtract 3...

Step-by-step explanation:

It should be

2x- 8= 5x+3

subtract 5x from both sides,

then add 8 onto both sides, then you would get 0 on one side, and 11 on the other so you would have

-3=11 which equals

Ollie says, 'The probability of a football team winning is 1/3 because winning is only one out of the possible outcomes -win,lose, draw.' Explain why Ollie is wrong

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

The possible outcome of football game is truly (Win lose or draw), hence, if the outcome only depends on just that one team, then the probability of winning is (required / total possible outcomes ; = 1/3). However, in football a game is played with an opposition team, of which there is a lot to consider in other to arrive at a winning probability, one is the relative strength of the teams, result of past meetings and so on. Hence, concluding that the probability of wining a football match is 1/3 based on the possible outcome (Win, lose or draw) is wrong.

En una encuesta, en un barrio se han contado 35 casas. Tres quintos de las casas tienen energía eléctrica. De estos, dos tercios tienen internet.

Answers

Responder:

21 casas;

2/5

Explicación paso a paso:

Dado que :

Total de casas = 35

Fracción con electricidad = 3/5

Número de casas con electricidad:

Fracción con electricidad * número de casas

3/5 * 35 = (3 * 35) / 5 = 105/5 = 21 casas

Fracción de todas las casas con internet:

2/3 de las casas con luz tienen internet

2/3 * 21 = 42/3 = 14 casas

14/35 = 2/5

Por lo tanto, Fracción de todas las casas con internet = 2/5

Find the angle of the least positive measure (in degrees, not equal to the given measure) that is coterminal with A.
A= -647°

Answers

9514 1404 393

Answer:

  73°

Step-by-step explanation:

A coterminal angle will be one that is this angle plus some multiple of 360°. We observe that the magnitude of the given value is between 360 and 720, so we can find the coterminal angle of interest by adding 720°.

  -647° +720° = 73°

The least positive measure angle coterminal with A is 73°.
