Answer:
h = 7 + 6x
Step-by-step explanation:
Since we are trying to find the height of the tree, we put h on the left side of the equation. Since the tree is 7ft tall at the moment, we write 7ft on the right side of the equation. Knowing that the tree grows 6 inches each year (x) we write 6x on the right side of the equation.
Answer:
-1
Step-by-step explanation:
4(x+3)=8
4x+12=8
-12 -12
4x=-4
x=-1
Answer 1: 2/5= 6/15 3/15-6/15= -3/15
Answer 2: 7/10= 14/20
1/4= 5/20
difference- 9/20
Answer 3:
2 5/6= 17/6
3 2/5= 17/5
17/6 = 85/30
17/5= 102/30
187/30
Answer 4:
11/2
9/7
77/14
81/14
-4/14
Answer 5:
23/4
35/12
69/12+35/12= 104/12= 26/3
Answer:
25%
Step-by-step explanation:
25% us the answer. First: work out the difference (decrease) between the two numbers you are comparing.
Decrease = Original Number - New Number
Then: divide the decrease by the original number and multiply the answer by 100.
Answer:
$204.85
Step-by-step explanation:
Let the two legs be the adjacent and the opposite of the right triangle. To get the third side (the hypotenuse), we will use the pythagoras theorem;
Perimeter of the garden will be the sum of all the three sides.
Perimeter of the garden = 12 + 12 + 16.97
Perimeter of the garden = 40.97 feet
Since 1 foot = $5
40.97 feet = x
Cross multiply
1*x = 5*40.97
x = 204.85
Hence it will cost $204.85 to fence the entire perimeter of the garden
