Which equation is true when p=0.6

e-lub [12.9K]

Answer:

Step-by-step explanation:

Its not A because when you plug in 0.6 in for P it gives you 6.6=1.8. (0.6)+6=1.8

Its B because when you plug in 0.6 in for P it gives you 6=6.

10(0.6)=6

Its not C because when you plug in 0.6 in for P it gives you 0.36=10.

0.6(0.6)=10

Its not D because when you plug in 0.6 in for P it gives you -0.4=0.4.

(0.6)-1=0.4

Solve this if you can :) I will give brainliest

mafiozo [28]

Answer: This question cannot be answered.

Explanation:

If you add three odd numbers, the sum must also be an odd number. To get an even number, you have to add an even number of odd numbers, e.g. 2 or 4. Adding 3 odd numbers to get 30 is therefore not possible. So the question cannot be answered.

What much expression represents a rational number?

Pie

Answer:

$\displaystyle \frac{2}{7}+\sqrt{121}$

Step-by-step explanation:

Rational Numbers

A rational number is any number that can be expressed as a fraction

$\displaystyle \frac{a}{b}, \ b\neq 0$

for a and b any integer and b different from 0.

As a consequence, any number that cannot be expressed as a fraction or rational number is defined as an Irrational number.

Let's analyze each one of the given options

$\displaystyle \frac{5}{9}+\sqrt{18}$

The first part of the number is indeed a rational number, but the second part is a square root whose result cannot be expressed as a rational, thus the number is not rational

$\pi + \sqrt{16}$

The second part is an exact square root (resulting 4) but the first part is a known irrational number called pi. It's not possible to express pi as a fraction, thus the number is irrational

$\displaystyle \frac{2}{7}+\sqrt{121}$

The square root of 121 is 11. It makes the whole number a sum of a rational number plus an integer, thus the given number is rational

$\displaystyle \frac{3}{10}+\sqrt{11}$

As with the first number, the square root is not exact. The sum of a rational number plus an irrational number gives an irrational number.

Correct option:

$\boxed{\displaystyle \frac{2}{7}+\sqrt{121}}$

How many solutions does the system have?

siniylev [52]

If you would like to know how many solutions does the system of two equations have, you can calculate this using the following steps:

x = -4y + 4 ... x + 4y = 4 /*(2)
2x + 8y = 8
____________
2x + 8y = 8
2x + 8y = 8
____________
0 = 0

The correct result would be infinitely many solutions.
