Answer:
The answer is
3P+2B=15.50
P+4B=20
Where P=pizza slice and B=burger
B=4.45
P=2.20
Step-by-step explanation:
The system proposal is
3P+2B=15.50
P+4B=20
Solving for P in the second equation, we have
P=20-4B and replace in first equation we have:
3(20-4B)+2B=15.50
Solving for B:
B=(60-15.5)/10=4.45
Replace B in first equation
P=20-4B=20-4(4.45)=2.20
Answer:
0.4444... repeated
Step-by-step explanation:
2 divide by 45 is 0.444... repeated.
2/5 is the first simplification, and 1/9 is correct
Factor the expression completely.
The factors of the equation 4x²+12x -72 will be 4(x-3)(x+6).
A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is2.
Factor out the 4 first since all numbers are divisible by 4. That leaves us with x² +3x -18.
4( x² +3x -18 ) = 4 ( x² + 6x - 3x -18 )
= 4 ( x(x+6) -3 (x + 6)
= 4 ( x + 6 ) ( x - 3 )
Hence, the factors are 4 ( x + 6 ) ( x - 3 ).

Answer:
Answer:
4(x-3)(x+6)
Step-by-step explanation:
We factor out the 4 first since all numbers are divisible by 4. That leaves us with x^2+3x-18.
Then we factor this to get (x-3)(x+6).
So the factored form of the equation is 4(x-3)(x+6)
