Help me find the value of "y" thanks

Help Me Find The Value Of "y" Thanks

Answers

Answer 1
You would move you positive 3 to the left side so (y) is by itself. So you would have 3x-8=y. Then substitute X=5. So 3(5)-8=y. 15-8=y. 7=y
Answer 2

Answer:

[tex]y=3x-8[/tex]

Step-by-step explanation:

First, you have to isolate y on one side of the equation.

Step 1) Add 5 to both sides (this will cancel out the (-5) on the left)

Step 2) Subtract 3x from both sides (this will cancel out the (3x) on the left)

Step 3) Subtract y from both sides

Step 4) In order to make the desired variable positive, change the sign of everything in the equation

The step shown above will yield the answer of [tex]y=3x-8[/tex]

Hey guys this is confusing, someone plz help

Answers

Answer: x = 13

Step-by-step explanation:

To find the value of x, you have to find ∠QRP

∠QRP + ∠QRS = 180

∠QRP + 95 = 180

Subtract 95 from both sides

∠QRP = 85

∠RQP + ∠QPR + ∠QRP = 180   Definition of triangle

(4x + 3) + (3x + 1) + 85 = 180

Subtract 85 from both sides

(4x + 3) + (3x + 1) = 95

7x + 4 = 95

Subtract 4 from both sides

7x = 91

Divide 7 from both sides

x = 13

Answers

Answer:

45 / 5 can be simplified to 9

Answer:

Scott has 9 football cards.

Step-by-step explanation:

On a team 5 girls and 2 boys scored a total of 41 points. The difference between the number of points scored by the 5 girls and the number of points scored by the
2 boys is 29. Each girl scored the same number of points and each boy scored the same number of points. Find the number of points scored by each girl and each
boy
Each girl scored points

Answers

Step-by-step explanation:

Let x be the number of points the 5 girls scored.

=> 41 - x is the number of points the 2 boys scored.

We have x + 29 = 41 - x or x - 29 = 41 - x.

=> 2x = 12 or 2x = 70

=> x = 6 or x = 35

We reject x = 6 as 6 is not a multiple of 5. (Each girl would have scored 1.2 points which is absurb)

So x = 35, each girl scored 35/5 = 7 points.

=> 41 - (35) = 6, each boy scored 6/2 = 3 points.
