Answer:

15

Step-by-step explanation:

First, find x

set your formula up as 3x+5=6x-10, since AB and DC are the same length.

This means x = 5

Now substitute 5 for x in the line DA

4x-5

4 * 5 - 5 = 15

What is the answer 4+3x = -2y
lilavasa [31]
First add 2y to both sides
so 4 + 3x + 2y = 0
then subtract 4 from both sides
so 3x + 2y = -4
that is standard form
now subtract 3x from both sides
2y = 3x - 4
now divide by 2 on both sides
y = 1.5x - 2
This is solved for y and is slope intercept form
starting from original subtract 4 from both sides
so 3x = -2x -4
now divide by 3 on both sides
so x = -2/3x -4/3
this is solved for x
hope any of that is what you needed.

PLEASE HELP URGENT!!!!
Dovator [93]

Answer:

£ 21552.13

Step-by-step explanation:

P= £18790

r =4.9% = \frac{4.9}{100}=0.049

t = 3 years

I = Prt

I = 18790 * 0.049 * 3

 =£ 2762.13

After 3 years , the amount in Dan's account = 18790 + 2762.13

                                                                         = £ 21552.13

Is anyone able to give a step by step process to this?

Answer:

The value of y is 3 cm.

Step-by-step explanation:

Given,

Perimeter of triangle = 29\ cm

Solution,

Lets redraw the triangle with nomenclature ABC, given in the attachment.

∴P(ΔABC) = 29 cm  (P stands for perimeter)

Length of AB = y+9

Length of BC = 2y

Length of CA = 4y-1

Now, we all know that the perimeter of a triangle is sum of all the three sides of triangle.

P(ΔABC) = Length of AB+Length of BC+Length of CA

On substituting the values, we get;

(y+9)+2y+(4y-1)=29\\y+2y+4y+9-1=29\\7y+8=29\\7y=29-8\\7y=21\\y=\frac{21}{7} =3\ cm

Length of AB =y+9=3+9=12\ cm

Length of BC =2y=2\times3=6\ cm

Length of CA =4y-1=4\times3-1=12-1=11\ cm

Hence the value of y is 3 cm.

Divide both sides by 4pi, then take the square root of both sides. You will not get an actual value, but the answer should be
\sqrt{ \frac{a}{4\pi} }
