-4.75 ​= x/2 what is x

Answers

Answer 1
Answer:

Answer:

x= -9.5

Step-by-step explanation:

We want to find out what the variable, x, is equal to. Therefore, we must isolate the variable on one side of the equation.

-4.75 = x/2

x is being divided by 2. The inverse of division is multiplication. Multiply both sides of the equation by 2.

2*(-4.75) = (x/2)*2

2*(-4.75)=x

2* -4.75=x

Multiply 2 and -4.75

-9.5=x

Let's check our solution. Plug -9.5 back in for x and solve.

-4.75= x/2

-4.75= -9.5/2

-4.75= -4.75

This checks out, so we know our solution is correct.

x is equal to -9.5
Answer 2
Answer:

Answer:

x = (19)/(2)

Step-by-step explanation:

(x)/(2) = - 4.75

First convert the decimal to an improper fraction

That's

- 4.75 = - (19)/(4)

So we have

(x)/(2) = - (19)/(4)

Cross multiply

4x = - 38

Divide both sides by 4

We have the final answer as

x = (19)/(2)

Hope this helps you

Which economic indicator measure inflation?

A. GDP
B. CPI
C. Unemployment rate

Answers

The "Economic-Indicator" which measures inflation is the : (b) Consumer Price Index (CPI).

The CPI tracks the average price changes of a basket of goods and services over time, reflecting the cost of living for consumers. It measures the inflation rate by comparing the price changes of this basket of goods and services from one period to another.

By tracking CPI, economists and policymakers can assess general level of price inflation in an economy. GDP (Gross Domestic Product) is a measure of the total value of goods and services produced in an economy, while unemployment rate reflects percentage of labor force that is unemployed and actively seeking employment, which is not directly related to measuring inflation.

Therefore, the correct option is (b).

Which correctly describes how the graph of the inequality 5x + 2y ≥ 13 is shaded? (1 point) Above the solid line Below the solid line Above the dashed line Below the dashed line

Answers

Answer:

The graph of inequality 5x+2y\geq 13 is above the solid line.

Step-by-step explanation:

Step-by-step explanation:

An inequality on a coordinate plane consist of a boundary line and an area in which each point is a possible solution.

* If the inequality has a sign  or  , then the line will be a solid line and its point are included in the solution.

* If the inequality has a sign '>' or '<' , then the line will be a dotted line and its point are not  included in the solution.

Given: The linear inequality: 5x+2y\geq 13

Then, the equation of the boundary line is;  5x+2y =13        ......[1]

we can write this as;

2y = -5x+13

Divide by 2 we get;

y = -(5)/(2) x + (13)/(2)                      ......[2]

Compare this  boundary line equation with the general point slope intercept line i.e, y = mx+b where m is the slope and b is the y-intercept.

Therefore, the slope of the this line is, m =-(5)/(2)

and a y-intercept (b) = (13)/(2) = 6.5

To find x -intercept:

Substitute y =0 in to solve for x;

5x+0 =13

Simplify:

x =(13)/(5) = 2.6

Therefore, the x-intercept is 2.6

Now,

Plot y = -(5)/(2) x + (13)/(2) ( as a solid line because y\geq  included equal to)

and shade the area above as 5x+2y\geq 13  as shown below in the graph
The answer is above the solid line.

Kayla pays her plumber $22 per hour to replace her drain pipe. She ends up paying him $99. Which equation can you use to find h, the number of hours the plumber worked?

Answers

Simple....

so, if she payed him $99 in total and she payed him $22 dollars per hour...

just make it...

99=22h
and...

(99)/(22)= (22h)/(22)

4.5=h

Thus, the plumber worked 4.5 hours. (4 and a half hours)
Let's see... 
.
FORMULAS!! Or equations too...
.
Sorry, we just have to, even if you don't want to.
.
$22x = $99, where x is the numbers of hours the plumber worked.
.
Now this is REALLY easy.
.
Divide 22 on both sides!!
.
22x/22 = 99/22.
.
So... what's 99/22?
.
4.5.
.
The plumber worked 4.5 hours.
