a) Expand and simplify.
3(x - 2) - 4(x - 5)
7​

Answers

Answer 1

Answer:

x=7

Step-by-step explanation:

3(x - 2) - 4(x - 5)=​7​

3x+−6+−4x+20=7

(3x+−4x)+(−6+20)=7(Combine Like Terms)

−x+14=7

−x+14=7

Step 2: Subtract 14 from both sides.

−x+14−14=7−14

−x=−7

Step 3: Divide both sides by -1.

−x

−1

=

−7

In a class of 29 children, 15 like history and 21 like math. They all like at least one of
the two subjects.
What is the probability that a child chosen at random from the class likes math but
not history?

Answers

Answer:

14/29

Step-by-step explanation:

The probability that a child chosen at random from the class likes math but not history is 14/29  or 0.4827.

It is given that the in a class of 29 children, 15 likes history and 21 like math.

It is required to find the probability that a child chosen at random from the class likes math but not history if they all like at least one of the two subjects.

What is the Venn diagram?

It is defined as the diagram that shows a logical relation between sets.

The Venn diagram consists of circles to show the logical relation.

We have:

Total students in a class = 29

First we have to find the number of students who likes both subject for this we have draw a Venn diagram shown in the picture.

From the Venn diagram number of students who likes both = 7

And number of students likes only math = 14

Hence, the probability will be:

[tex]p = \frac{14}{29}[/tex]   ( because total number of students is 29)

or P = 0.4827 or 48.27%

Thus, the probability that a child chosen at random from the class likes math but not history is 14/29  or 0.4827.

The astronomers measure each planet's orbital period, as shown in the table. Planet; Orbital Period (Earth days) Planet W; 10 Planet X; 640 Planet Y; 80 Planet Z; 270 To determine the distance each planet is from the star, astronomers applied one of Kepler's three laws. Kepler's first law: The path of each planet around a star is an ellipse, with the star at one focus. Kepler's second law: A planet sweeps out equal areas in equal amounts of time as it revolves around the star.Kepler's third law: The square of the time for one revolution of a planet is proportional to the cube of the radius of its orbit.
