4004 + 50.50t = 300.75t
4004 = 300.75t - 50.50t
4004 = 250.25t
4004 / 250.25 = t
16 = t <=== they charge the same at 16 tons
300.75(16) = 4812 <== they cost the same
Do what? If you mean to find when it equals zero...
By inspection you can see that if x=0 or 2 the expression is equal to zero...
You multiply each term in the parentheses by the term outside the parentheses...like:
3x*3x+3x*6 which is equal to:
9x^2+18x If you meant to expand it....
9x(x+2) If you meant to factor it completely
Answer:
22/10 or 11/5
Step-by-step explanation:
There are two (2) whole and two tenths (2/10).
You have to multiply the 2 whole by the denominator and add it to the numerator.
Step by step:
1) 2 and 2/10
2) (2*10) = 20
3) add 20 to 2, then put it on the /10
4) 22/10, then reduce the fraction
5) 11/5
Final answer: 11/5

Answer:
it has no solutions
Step-by-step explanation:
y = mx + b
y = -5x - 1......slope here is -5 and y int is -1
y = -5x + 7....slope here is -5 and y int is 7
