The answer is 50, numerical just means by way of numbers
Answer:
x = -5 and y = 8
Step-by-step explanation:
To solve the system by substitution, solve one equation for a variable. Then substitute the equation into the other equation.
x + 2y = 11 becomes x = 11 - 2y
Substitute x = 11 -2y into 4x + 4y = 12.
4(11-2y) + 4y = 12
44 - 8y + 4y = 12
44 - 4y = 12
32 = 4y
y = 8
Substitute again with y = 8 into the equation to find x.
x = 11 - 2(8)
x = 11 - 16
x = -5

The pool is full when the time is zero:
It is emptied (-) in the rate 150 gallons every hour.
Answer:
Step-by-step explanation:
- Binomial: 2 terms
- Trinomial: 3 terms
- Linear: a straight line
- Quadratic: like a curved line
(3x + 2) - (x + 5)
1(3x + 2) - 1(x + 5)
3x + 2 - x - 5 <== combine like terms
3x - x + 2 - 5
2x - 3 <== final answer, linear binomial
(2x + 8) + (3x² - 2)
1(2x + 8) + 1(3x² - 2)
2x + 8 + 3x² - 2
3x² + 2x + 6 <== final answer, quadratic trinomial
(3x + 8) + (4x² - x)
1(3x + 8) + 1(4x² - x)
3x + 8 + 4x² - x
4x² + 2x + 8 <== final answer, quadratic trinomial
(x² + 5x minus (-) 2) + (8 minus (-) 5x)
(x² + 5x - 2) + (8 - 5x)
1(x² + 5x - 2) + 1(8 - 5x)
x² + 5x - 2 + 8 - 5x
x² + 6 <== final answer, quadratic binomial
(x² + 7x) - (x² + 5)
1(x² + 7x) - 1(x² + 5)
x² + 7x - x² - 5
7x - 5 <== final answer, linear binomial
Hope this helps!
Answer:
Step-by-step explanation:
if 600 represents ........................15%
x.................................................100%
(600*100)/15=4000
