Simplify the expression:
8(2x - 3) - 6x = 8×2x - 8×3 - 6x = 16x - 24 - 6x = 10x - 24
for x=3
put value of "x" to the expression:
<u>10×3 - 24 = 30 - 24 = 6</u>
Answer:
the answer is uh..21
Step-by-step explanation:
Cancel the common Factors of 3^2 and 3
Which will equal 7x(3)
Multiply 7x(3)
That would be 21 :)

Answer:
2.5
Step-by-step explanation: i just solved it and it was correct. 300-250=50 50 divided by 20 is 2.5. you divide it by 20 because you have to isolate h in 20h by itself. and to do that you divide 20h by 20
Answer is C. multiply by 3 - square root 5
using a^2 - b^2 = (a + b)(a - b)
First let us calculate the total cost before tax:
1.06 * cost = 16.43
cost = 15.5
Therefore the cost of sunscreen is:
2 * Sunscreen + 6.50 = 15.5
2 * Sunscreen = 9
Sunscreen = $4.50
<span>Hence each bottle of sunscreen cost $4.50</span>
