Answer:

X=7

Step-by-step explanation:

in order to get everything out of the square root, just square both sides.

This will give you x + 1 = 2x - 6

move like terms to each side and you’ll end up with x = 7

Estimate how much MORE water it would take to completely FILL the vase to the top?
MariettaO [177]

Answer:

81πinc^3

Step-by-step explanation:

Volume of glass = π(3)^2(12) = 108πin^3

Volume of water in glass = π(3)^2(3) = 27πin^3

Volume needed to fill completely = 108π - 27π = 81π^3

A golf tournament has five rounds. The players are given scores for each round based on how many strokes they are above or below
frozen [14]

We have the following table:

Round Number of Strokes Above or Below 72

1 -5

2 +6

3 -2

4 -4

5 +5

So, the expression that represents the total number of strokes is:

72 + (Number of strokes Above or below 72)

Therefore, for every round we get:

Round Number of Strokes Above or Below 72 Total number of strokes

1 -5 72 - 5 = 67

2 +6 72 + 6 = 78

3 -2 72 - 2 = 70

4 -4 72 - 4 = 68

5 +5 72 + 5 = 77

The total number of strokes is:

67 + 78 + 70 + 68 + 77 = 360

Additionally, the average is the total number of strokes divided by the number of rounds, so it is equal to:

\frac{360}{5}=72

Answer: Total: 360 Strokes

Average: 72 Strokes
