All you have to do is plug and solve...
2(q+2) + 3q = -26
2q + 4 + 3q = -26
Subtract 4 from the left side and move it to the right...
2q + 4 + 3q = -26
- 4 - 04
_________________
2q + 3q = -30
Now add 3q and 2q together and you get 5q, next divide...
5q = -30
_______
5 5
Finally, you get q equal to negative 6 (-6)!
Answer:
$6,750
Step-by-step explanation:
5% × $135,000 = 5/100 × 135,000
= $6,750
Only the coefficients change, not the exponents when adding
-8n^2 + n + 1
Answer:
C = 250S + 4500
17 tons = $8750
simply plug in 17 into the variable S and solve for C to find the total cost
