3x+1. I need to find and write an equation for x

Alchen [17]

Answer:

$x =\frac{-1}{3}$

Step-by-step explanation:

As the given algebraic expression is

$3x+1$

In order to solve the expression $3x+1$ for x, we have to

$3x+1=0$

Step 1: Subtract 1 from both sides

$3x+1-1=0-1$

$3x=-1$

Step 2: Divide both sides by 3.

$\frac{3x}{3} =\frac{-1}{3}$

$x =\frac{-1}{3}$

Therefore, $x =\frac{-1}{3}$

How do you work out the equation 1-x=9.

mafiozo [28]

Answer:

x=8

Step-by-step explanation:

x + 1 = 9

Simplifying

x + 1 = 9

Reorder the terms:

1 + x = 9

Solving

1 + x = 9

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1' to each side of the equation.

1 + -1 + x = 9 + -1

Combine like terms: 1 + -1 = 0

0 + x = 9 + -1

x = 9 + -1

Combine like terms: 9 + -1 = 8

x = 8

Simplifying

x = 8

Nadusha1986 [10]

Answer:

Yes, to calculate probability of having death case after contracting Corona virus 19 in the US

Step-by-step explanation:

The common news is the outbreak of corona virus 19 and I was curious to know the probability that after contracting the disease, what is the probability of reporting death with respect to the data from the US. By 1st April, the US had reported 4075 deaths due to Corona virus 19 and the total infection cases were 189, 445. This means that the probability of reporting death after contracting the virus is $\frac {4075}{189445}= 0.0215102008498\approx 0.0215\ or 2.15\%$
