3/8 is between 0 and -1/3. We need to determine if 3/8 is closer to -1/3 or closer to zero. Since -1/3 is smaller than 3/8, 3/8 is closer to -1/3. Since 3/8 is closer to -1/3, 3/8 rounded to the nearest -1/3 is -1/3.

Answer:

The first number is -2 and the second number is 1

see the procedure

Step-by-step explanation:

The complete question is

Translate to a system equation

Twice a number plus three times a second number is negative one. The first number plus four times the second number is two.

Call the first number m and the second number n

Let

m ----> the first number

n ----> the second number

we know that

$2m+3n=-1$ ----> equation A

$m+4n=2$ ----> $m=2-4n$ ----> equation B

Solve the system by substitution

Substitute equation B in equation A

$2(2-4n)+3n=-1$

solve for n

$4-8n+3n=-1$

$5n=4+1$

$n=1$

Find the value of m

$m=2-4n$ ----> $m=2-4(1)=-2$

therefore

The first number is -2 and the second number is 1

Please, I need help ASAP! Which of the following shows the true solution to the logarithmic equation mc019-1.jpg

X = 1 is the correct answer.
Using the log properties, remember that Log(base2)2 = 1

3log(base2)2x = 3
divide both sides by 3
log(base 2)2x = 1
log(base2)2 = 1
1 * x = 1
x = 1
