Answer:

Drawing a quick picture is helpful when adding decimals because it gives you a visual picture of what the answer is. Also, it gives you the opportunity to be sure that you got the correct answer because computations in adding may have some mistakes.

Step-by-step explanation:

9514 1404 393

Answer:

  (2x +1)/(4x^2) . . . . except x=0, -1

Step-by-step explanation:

Addition of fractions works in the usual way:

  a/b +c/d = (ad +bc)/(bd)

Division of fractions works in the usual way:

  (a/b)/(c/d) = (ad)/(bc)

__

  [tex]\dfrac{\left(\dfrac{1}{2x}+\dfrac{1}{2x+2}\right)}{\left(\dfrac{2x}{x+1}\right)}=\dfrac{1}{2}\cdot\dfrac{\left(\dfrac{1}{x}+\dfrac{1}{x+1}\right)}{\left(\dfrac{2x}{x+1}\right)}=\dfrac{1}{2}\cdot\dfrac{\left(\dfrac{2x+1}{x(x+1)}\right)}{\left(\dfrac{2x^2}{x(x+1)}\right)}\\\\=\boxed{\dfrac{2x+1}{4x^2}}[/tex]

The expression is undefined for any denominator equal to zero: x=0 or x=-1.

Answer:

AED 210

Step-by-step explanation:

If the cost of 7 toys is AED 294, this is written as;

7 toys = AED 294

To get the cost of 5 toys, this is written as;

5 toys = x

Divide both expressions

7/5 = 294/x

Cross multiply

7x = 5 * 294

7x = 1470

x = 1470/7

x = 210

Hence the cost of 5 toys is AED 210

Answer:

The goal post is 40.05 feet tall.

Step-by-step explanation:First, you need to decide whether to use sin, tan or cos.

You have the angle, the adjacent and need the opposite , so you need to find out which one has all three values in

Sin  

Cos  

Tan  

So you need to use tan.

Tan = opposite / adjacent, so rearrange the formula to make opposite the subject:

[tex]Opp = Tan * adj

So simply plug these values in:

[tex]Opp =131 * tan(17) = 40.05

So the goal post is 40.05 feet tall

Answer:

My calculator says 165.789

Answer:

ELLA

Step-by-step explanation:

Given that :

Distance covered by Ella = 5/10

Distance covered by Sam = 7/8

Comparing each distance to 1/2

Ella = 5/ 10 = 1/2 ; 1/2 = 1/2 = 0.5

Sam = 7/8 = 0.875 ; comparing with 1/2

0.875 > 0.5

Given

Sam ran farther Than ELLA

Because 0.875 > 1/2

0.875 - 0. 5 = 0.375

Answer:

y = 5x + 1

Step-by-step explanation:

Hello There!

Equations that have no solutions are parallel

So the line we are going to create an equation for has the same slope as the line drawn  

To find the slope we do change in y divided by change in x

as y goes 5 x goes up 1

so the slope is 5/1 or 5

The requirements for the equation is it has to go through the points (0,1)

The ordered pair listed is the y intercept so the equation would be

y = 5x + 1

Answer:

-8a - 6b

Step-by-step explanation:

6a - 13b - 14a + 7b =

6a-14a = -8a

-13b + 7b = -6b

-8a - 6b

I dont see the numbers sorrry

Answer:

neptune = 6m+2

Step-by-step explanation:

mars has 'm' moons

pluto has one more than twice that of mars, = 2m+1

neptune is one less than thrice of pluto

= 3(2m+1) -1

= 6m+3 -1

= 6m+2

His hourly rate is:

242/11=22 dollars

( dollars/hour ) x ( hours worked ) = dollars earned

Let t= hours worked

22t+=198

t=198/22

t=9

Yolanda needs to work 9 hrs

Answer:

60 kilograms of the 30% solution

140 kilograms of the 40% solution

Step-by-step explanation:

Let x = the no. of kilos containing 30% salt (solution 1)

and 200 - x = the no. of kilos containging 40% salt solution 2)

.30x = amount of salt in solution 1

.40(200 - x) = amount of salt in solution 2

.37(200) = amount of salt in the final mixture

salt in solution 1 + salt in solution 2 = salt in final mix.

.30x + .40(200 - x) = .37(200)  

Let's multiply thru the equation by 100 to remove the decimal fractions

30x + 40(200 - x) = 37(200)

30x + 8000 - 40x = 7400

-10x = -600

x = 60 kilograms of the 30% solution

200 - 60 = 140 kilograms of the 40% solution

Honest people would tell other people what they think honestly. And honestly, I don't know how to answer your question :( Honestly, I feel like I don't deserve to answer this question if I can't come up with an honest answer. I don't know, maybe I come back to this question another day when I'm older and wiser, and have an answer that will impress you with my honesty. But for now, honestly, I feel like I have failed this user.

Answer: -45°

Step-by-step explanation: This is because if it changes -3°F every minute and there are 15 minutes, just do 15*-3. In this case, is -45°

Answer:

4 1/2 tiles are needed to cover this area

Step-by-step explanation:

Mathematically, the area of a parallelogram is the product of the base and the height

We have this as;

24 * 10 = 240 cm^2

So the area of a tile is this

The number of tiles that will cover the given area will be;

1080/240 = 4.5 tiles

Answer:

Answer:

RQ = 10

Step-by-step explanation:

When two triangles are similar, the ratio of their corresponding sides are equal;

Thus, we have it that;

QP/RQ = BC/AB

12/RQ = 36/30

RQ = 12 * 30/36 = 10

Answer:

50,000 Square Miles.

Step-by-step explanation:

Answer:

ok

Step-by-step explanation:

Answer:

Step-by-step explanation:

y = mx +b

Here, m is slope and b is y-intercept

1) y = -5x - 6

Slope = -5

y-intercept = -6

2) y = 2x

Slope = 2

y-intercept = 0
