Mathematics
1 answer:
devlian [24]3 years ago
3 0

Answer:

The value of x is 20.

Step-by-step explanation:

Given that

Number of songs Marcus has = 10x+8

Number of songs Lara has = 15x-92

It is also given that they have the same number of songs that means both the expressions should be equal.

Putting both equal

10x+8 = 15x-92

This is a linear equation in one variable which can be solved using properties of equality

Subtracting 10 from both sides

10x+8-10x = 15x-92-10x\\8 = 5x-92

Adding 92 on both sides

8+92 = 5x-92+92\\100 = 5x

Dividing both sides by 5

\frac{5x}{5} = \frac{100}{5}\\x  = 20

Hence,

The value of x is 20.

There are 70 students in the school band. 40% of them are sixth graders, 20% are seventh graders, and the rest are eighth grader
Inessa05 [86]

Answer:

28

Step-by-step explanation:

40% 6th graders of 70 total = 28 6th graders

40% 6th graders + 20% 7th graders = 60%

100% - 60% = 40% 8th graders

40% are 8th graders therefore the answer is 28

Kenji earned the test scores below in English class.
lutik1710 [3]

Answer:

mean=87

median=87

Step-by-step explanation:

mean=sum of test score/number of subject

mean=79+91+93+85+86+88/6

mean=522/6

mean=87

Literal meaning of median is medium.

To find the number which lies in the medium, we must rearrange the number in ascending.

79, 91, 93, 85, 86, 88

79, 85, 86, 88, 91, 93

86+88/2=87

Hope this helps ;) ❤❤❤

What are the real and imaginary parts of the complex number?
Licemer1 [7]

Answer:

The real part is 2

The imaginary part is -5

Step-by-step explanation:

A complex number consists of a real part and an imaginary part. For example given the complex number z = x+it

x is the real part of the complex number z i.e Re(z) = x

Imaginary part of the complex number z is y i.e Im(z) = y.

Note that the real part are on the x axis of a graph while the y axis is the imaginary axis attached to the complex notation i

Given the complex number 2-5i

Comparing 2-5i to x+iy

x= 2 and y = -5

The real part is 2 (value that is not attached to the complex notation)

The imaginary part is 5(value attached to the complex notation)
