2x-7=-3x+18


solve for x

Answers

Answer 1

Answer:

x=5

Step-by-step explanation:

2x−7=−3x+18

Step 1: Add 3x to both sides.

2x−7+3x=−3x+18+3x

5x−7=18

Step 2: Add 7 to both sides.

5x−7+7=18+7

5x=25

Step 3: Divide both sides by 5.

5x

5

=

25

5

x=5

Answer 2

Answer:

x = 5

Step-by-step explanation:

2x - 7 = -3x + 18

2x - 7 + 7 = -3x  + 18 + 7

2x = -3x + 25

2x + 3x = -3x + 25 + 3x

5x = 25

x = 5

A triangle has sides represented by 7, x, and x−1. If the perimeter is 28, find the length of the longest side.

Answers

Answer:

x (11 unit) is the longest side

Step-by-step explanation:

Given:

Sides;

7, x, and x−1

Perimeter = 28

Find:

Longest side

Computation:

Perimeter = sum of all sides

So,

7 + x + (x -1) = 28

2x + 6 = 28

x = 11

So,

x -1 = 11 - 1 = 10 unit

x (11 unit) is the longest side

James:

Marks

Sarah:

Robert

Answers

Answer:

James = 119 points

Sarah = 357 points

Roberts = 51 points

Step-by-step explanation:

Given that :

James = x points

Sarah = 3x points

Roberts = x - 68 points

Each point = 3 pence

All students have a total of £15.81

1 pound = 100 pence

£15.81 pound = 1581 pence

3x + 3(3x) + 3(x - 68) = 1581

3x + 9x + 3x - 204 = 1581

15x - 204 = 1581

15x = 1581 + 204

15x = 1785

x = 1785 / 15

x = 119

Hence,

James = 119 points

Sarah = 119 * 3 = 357 points

Roberts = 119 - 68 = 51 points

Ir (2p-1,p) is a solution of the equation 9y + 12 = 10x, then find the value of p​

Answers

Answer:

p = 2

Step-by-step explanation:

Since, (2p-1,p) is a solution of the equation 9y + 12 = 10x.

Therefore, plug x = 2p - 1 & y = p in the above equation.

9p + 12 = 10(2p - 1)

9p + 12 = 20p - 10

12 + 10 = 20p - 9p

22 = 11p

p = 22/11

p = 2

There were 450 people at a play. The admission price was $2 for adults and $1 for children. The admission receipts were $680. How many adults in how many children attended

Answers

Answer:

Adults= 110

Children= 340

Step-by-step explanation:

Given data

let adults be x

and children be y

x+y= 450----------1

2x+y=680---------2

from 1

x= 450-y

put this in 2

2(450-y)=680

900-2y=680

900-680=2y

220=2y

y= 220/2

y= 110

x+110= 450

x= 450-110

x=340
