Answers

Answer: x = 45

simplify both sides of the equation.

3/25x + -14/5 = 13/5

add 14/5 to both sides.

3/25x = 27/5

multiply both sides by 25/3.

x = 45

Answer:

the only thing is that your dot should be an open circle because 11 is not included in the answer. If it was less than or equal too, you have a closed dot, but since its just less than its an open dot. I like to think of it like if its closed dot its included, and if its an open dot it falls through the hole and is not included. I don't know if that makes sense, but you've got it otherwise.

Find the length of TU as indicates in the picture, will name Brainliest.

Answers

Answer:

7

Step-by-step explanation:

2x-5 + 2x-7 = 12

this is because the length of the line is given to be 12

so the sum of the two equations should be 12

2x+2x -5-7 = 12

4x - 12 = 12

4x = 12+12

4x = 24

x = 6

there TU = 2x-5 =2(6) -5 =12-5=7

TU = 7

How is the percentage of a value calculated?

The percentage represents a value divided by 100. In this way, saying 25% of a value is the same as saying 25 out of 100, that is, 25 divided by 100. And to find the exact number of absentees in the event, just multiply the whole by the percentage

So in this case, we have the information that:

May: 223 Dinztop salesJune: 148 Dinztop sales.

Using the percentage we have:

[tex]p=\frac{148}{223} = 0.6637[/tex]

This value in percentage that will be:

[tex]0.6637*100\%= 66.37\%[/tex]

Because of the same percent rate, the amoutns sold in June:

[tex]66.37\%*148=98[/tex]

Anna and Paddy take part in the same fun run.
Anna completed the fun run in 2 hours.
Her average speed was 6 kilometres per hour.
Paddy completed the fun run in 90 minutes.
(a) Work out Paddy's average speed in kilometres per hour.

Answers

Answer:

I wanna say 4.6 kmph

Step-by-step explanation:

6(average) /2(hr)=3kmph

1.20(hr) / 6 (kmph) = 4.6

If Anna and Paddy take part in the same fun run. Anna completed the fun run in 2 hours. Her average speed was 6 kilometres per hour. Paddy completed the fun run in 90 minutes. Then 4.5 km/h is Paddy's average speed

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

Anna and Paddy take part in the same fun run. Anna completed the fun run in 2 hours.

Her average speed was 6 kilometres per hour.

Paddy completed the fun run in 90 minutes.

We need to find paddys  average speed in kilometres per hour.

Let us convert 2 hrs to minutes=120 minutes

6/120=x/90

Apply cross multiplication

90×6=120x

540=120x

Divide both sides by 120

x=4.5

Hence 4.5 kilometer per hour is the Paddy's average speed.
