2 tenths is equal to____ fifths

Answers

Answer 1

Answer: To solve this, it is easiest to set up a proportion, letting x represent the number that we don't know.

2/10 = x/5

Now, we can use cross products to simplify this proportion. Cross products sets the products of the numerator and denominator of separate fractions equal to one another. It results in the equation:

(5)(2) = (10)(x)

Let's multiply out these numbers to further simplify the equation.

10 = 10x

Finally, we have to divide both sides by 10, to get our variable x alone

x = 1

Therefore, 2 tenths is equal to 1 fifth.

1- Caleb's family room has the dimensions shown. He needs to find the area of the room so that he knows how much carpet to buy. Complete the area model below to find the area of the family room.

Answers

Answer: $20(11)/(32)\ sq\ yd$

Step-by-step explanation:

Given: The width of the room = $3(7)/(8)\ yd=(31)/(8)\ yd$

The length of the room = $1(5)/(4)\ yd=(21)/(4)\ yd$

The area of the rectangular room= $length * width$

⇒The area of the rectangular room= $(21)/(4)*(31)/(8)\ sq\ yd$

⇒The area of the rectangular room= $(651)/(32)\ sq\ yd$

⇒The area of the rectangular room= $20(11)/(32)\ sq\ yd$

Step 1: Define

Identify

z - 49 - 13 = 59

Step 2: Solve for z

Subtract: z - 62 = 69
[Addition Property of Equality] Add 62 on both sides: z = 131

Answer:

$\small \sf \: z = \fbox{121}$

Step-by-step explanation:

z - 49 - 13 = 59

We need to find z.

solve for z

z - 49 - 13= 59

combine like terms

z - 62 = 59

Add 62 to both sides

z - 62 + 62 = 59 + 62

z = 59 + 62

Add 59 and 62 to get 121.

z = 121

What is 7+x+5-3=16-8
what is x and how did you work it out

Answers

This problem is tough until you clean it up so you can see what's going on.

On the left side, (7 + 5 - 3) = 9 . So the left side is x + 9 .

On the right side, (16 - 8) = 8.

So the equation is really x + 9 = 8

Subtract 9 from each side: x = -1

$7+x+5-3=16-8 \n \n 7 + x + - 5 - 3 = 16 + - 8 \n \n (x) + (7 + 5 + - 3 ) = ( 16 + - 8 ) \n \n x + 9 = 8 \n \n x + 9 - 9 = 8 - 9 \n \n \huge{\boxed{ x = -1}}$

At 30 degrees, Edgardo said the temperature was warm enough to go swimming. Did he mean to give the temperature in Fahrenheit or Celsius. Explain.

Answers

30 Fahrenheit is just below the typical freezing temperature of water. 30 Celsius is just a few degrees below normal body temperature . . . nice for casual swimming. Edgardo might also have been referring to 30 degrees latitude.

Certainly in Celsius, because this temperature in Fahrenheit is a low temperature

2/3x - 7 = 11 answer is x=27 how do you get that answer

Answers

In an algebra problem, you don't set the answer-goal and say "Go for it!"

There is only one correct answer, so the only appropriate way to go about it is to say "Here is the equation. Find the solution.?"

Maybe 27 is the solution, and maybe it's not.
We're about to find out.

You said 2/3 x - 7 = 11

Add 7 to each side: 2/3 x      = 18

Divide each side by 2 : 1/3 x      = 9

Multiply each side by 3 :   x   = 27 .

So yes, the correct solution is 27. And that's how to find it.
