x = 5
Step-by-step explanation:
distribute 4 into (x - 8)
=> 4x - 32 + 2 = -10
combine like terms
=> 4x - 30 = -10
add 30 on both sides to isolate and solve for x
=> 4x = 20
divide both sides by 4
=> x = 5
The answer to this question should be -82y
Answer:
21n² - 28n + 7
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
3n(7n - 7) - 1(7n - 7) ← distribute both parenthesis
= 21n² - 21n - 7n + 7 ← collect like terms
= 21n² - 28n + 7

Step-by-step explanation:
Karens ration is 5:15 whilst chens is 6:19
