X = 18
Steps:
Remove the parenthesis...
4x-6+x = 12+4x
Then cancel out 4x...
-6+x = 12
Then regroup the terms...
x - 6 = 12
Add 6 to both sides...
x = 12 + 6
Then you get...
x = 18
Hope this helped!
Click on the image to see the answer
X + y + z = 54
y = x + 1
z = x + 2
x + x + 1 + x + 2 = 54
3x + 3 = 54
x + 1 = 18
x = 17
y = 17 + 1 = 18
z = 17 + 2 = 19
the three integers are 17, 18, and 19
The range is the difference between the largest and the smallest values.
largest value = 14
smallest value = 8
14 - 8 = 6
6 is your range.
Answer:
$101.97
Step-by-step explanation:
Diameter of circular wooden deck = 30 ft
Radius of the deck = ½ of diameter = ½*30 = 15 ft
Area of deck = πr² = 3.14*15² = 706.5 ft²
1 gallon covers 250 ft² (1 gallon = 250 ft²)
Let x be the number of gallons that will cover 706.5 ft² of the deck
Thus:
1 gallon = 250 ft²
x = 706.5 ft²
Cross multiply
1*706.5 = 250*x
706.5/250 = x
2.826 = x
Number of gallons to cover the deck is approximately 3 gallons (approximated to nearest whole number). Since the we can't buy a gallon that is not full, we approximate to give us 3 gallons.
1 gallon cost $33.99 (1 gallon = $33.99)
3 gallons cost: 3*33.99 = $101.97
