Step-by-step explanation:
x² + 3x - 15 = 2x - 13
x² + x - 2 = 0
(x + 2)(x - 1) = 0
By zero product rule, (x + 2) = 0 or (x - 1) = 0.
Hence x = -2 or x = 1.
Answer:
x = 14
Step-by-step explanation:
x- 9 = 5
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Add 9 to both sides of the equation:
x - 9 (+9) = 5 (+9)
x = 5 + 9
x = 14
x = 14 is your answer.

Answer:
A possible solution is 60/2 = 30
Step-by-step explanation:
The given parameters are;
The dividend is a factor of 60
The divisor is a factor of 18
The quotient is a multiple of 3
The dividend is the amount divided
The dividend is the number that is dividing the dividend
The quotient is the result of the division operation
The given numbers to use are 60, 2, 30, and 18
Therefore one possible solution is 60/2 = 30
The dividend = 60 which is a factor of 60 (60 × 1 = 60)
The divisor = 2 which is a factor of 18 (2 × 9 = 18)
The quotient = 30 which is a multiple of 3 (3 × 10 = 30)
Answer:
Number of jars can be filled from 15kg of the salt = 468 or 469 jars (Approx.)
Step-by-step explanation:
Given:
Amount of salt containing in jar = 32 gram
Total amount of salt in jar = 15 kg
Find:
Number of jars can be filled from 15kg of the salt
Computation:
Total amount of salt in jar = 15 kg
Total amount of salt in jar (in grams) = 15 x 1000 g
Total amount of salt in jar (in grams) = 15,000 g
Number of jars can be filled from 15kg of the salt = Total amount of salt in jar (in grams) / Amount of salt containing in jar
Number of jars can be filled from 15kg of the salt = 15,000 / 32
Number of jars can be filled from 15kg of the salt = 468.75
Number of jars can be filled from 15kg of the salt = 468 or 469 jars (Approx.)
