Answer:

Step-by-step explanation:

4x+4+2x+2+7x-8=180

add like terms

4x+2x+7x=13x

4+2-8=-2

13x-2=180

+2 +2

13x=182

/13 /13

x=14

now you plug in X

4(14)+4= 60

2(14)+2= 30

7(14)-8= 90

add ur stuff up see if u get 180

60+30+90=180

#1:

A)

you need to know where a vertex goes on a isosceles triangle...

I attached a picture that explains it.....

you also want to label triangle.... XYZ

I put a picture on of how you should of labeled the triangle...

B)

so we need to find Measure for each angle.... REMEMBER: A triangle angles needs to = 180.

so your equations will need to be equal to 180.

4x+4+2x+2+7x-8=180

so we combine liked terms

4x+2x+7x=13x

4+2-8=-2

13x-2=180

+2 +2

13x=182

/13 /13

x=14

now you plug in X

4(14)+4= 60

2(14)+2= 30

7(14)-8= 90

now you want to check you answers so add them up to see if your answers equal 180...

60+30+90=180

to be continued.... i do second question on a second answer since i dont want pictures to get mixed up

Answer:

260 stickers

Step-by-step explanation:

Let Gareth's stickers be x.

Hence Cheryl sticker is 160+x;

If Cheryl gave 185 stickers

to Gareth, it means:

Cheryl has at the moment;

160 + x - 185 = x - 25

At this time when Gareth receives 185 he now has:

x+ 185

Also when he receives x +185, he has 3 times Cherry's meaning:

x+185 =3(x-25)

x + 185 = 3x -75

185 + 75 = 3x-2x

260= x

x = 260.

Hence Gareth has 260 stickers

Which of the following correlation coefficients represents the strongest
erik [133]

Answer:

\boxed {\boxed {\sf -0.92}}

Step-by-step explanation:

A correlation coefficient is a number ranging from -1 and 1 that measures the strength and direction of a linear relationship.

  • If it is a negative number, the linear relationship is also negative. If it's positive, the relationship is positive.
  • The closer it is to -1 or 1, the stronger the relationship.

Since the question only asks for the strongest relationship and does not ask for the direction (positive/negative), we can simply choose the number closest to -1/1. Therefore, the answer is -0.92.

3x + ky = 8
djyliett [7]

Answer:

a) 3x + ky = 8

ky = 8 - 3x

x – 2ky = 5

x - 2(8 - 3x) = 5

x - 16 + 6x = 5

7x = 21

x = 3 (shown)

b) x-2ky = 5

sub x = 3, y = 1/2

3-2k(1/2) = 5

-2k = 2

k = -1
