Answer:
1. 6x = 18 (Divide by six on both sides
2. 
(the6 on the right side cancels out, you are left with 18/6)
3. x = 3
Step-by-step explanation:
Step-by-step explanation:
Divide 140 by 
to represent the amount of hours he worked.
To make dividing easier, can also represent 2.8 as a decimal.
He has worked 50 hours after completing 140 rows of grapes.
Answer:
Cos B = 4/5
Step-by-step explanation:
From the question given above, the following data were obtained:
Sine B = 3/5
Cos B =?
Recall:
Sine B = Opposite / Hypothenus
Sine B = 3/5
Therefore,
Opposite = 3
Hypothenus = 5
Next, we shall determine the Adjacent. This can be obtained as follow:
Opposite = 3
Hypothenus = 5
Adjacent =?
Hypo² = Adj² + Opp²
5² = Adj² + 3²
25 = Adj² + 9
Collect like terms
Adj² = 25 – 9
Adj² = 16
Take the square root of both side
Adj = √16
Adjacent = 4
Finally, we shall determine Cos B. This can be obtained as follow:
Hypothenus = 5
Adjacent = 4
Cos B =?
Cos B = Adjacent / Hypothenus
Cos B = 4/5
Answer:
Simplified: 4X^3
Step-by-step explanation:
Simplify the expression.
Answer:
A
Step-by-step explanation:
Expand parentheses:
Move all y's to one side and numbers to the other:
Divide both sides by -6. Since you are dividing both sides by a negative number, you need to flip the comparator:
