Solve for x<br> 3.24x + 8.37x -8.09=7.83<br> X= <br> Round your answer to the nearest hundredth
amm1812

3.24x + 8.37x -8.09=7.83

adding 3.24 x and 8.37x on the right side:

3.24x + 8.37x -8.09=7.83

11.61x -8.09=7.83

adding 8.09 to both sides:

11.61x =7.83+8.09

11.61x =7.83+8.09

11.61x =15.92

dividing both sides by 11.61

Answer : x=1.37

The cost of 3 notebooks and 2 pencils is $5.10. At the same prices, the cost of 2 notebooks and 3 pencils is $4.65. What is the
Pepsi [2]

Answer:

$1.95

Step-by-step explanation:

notebook = n

pencil = p

3n + 2p = 5.10

2n + 3p = 4.65

multiply top equation by 2 and bottom by 3

6n + 4p = 10.20

6n +9p = 13.95

subtract bottom equation from the top equation

-5p = -3.75

divide by 5, negatives cancel out

p  = 0.75

sub p into either equation, I chose the original top equation

3n + 2(0.75) = 5.10

3n + 1.50 = 5.10

subtract 1.50 from both sides

3n = 3.60

divide both sides by 3

n = 1.20

p = 0.75

n + p = 1.95 (the fourth option)
