Eighty four divided by 6 is 14
I'm assuming that you meant 4x+1=3x?
Subtracting 4x, we get 1=-x. Multiplying by -1, we get x=-1 as the solution.
Answer:
the answer to your question is 0.4375
Answer:
P=40
a + b + x = P
a = 3x
b = x + 5
substitute for b & y
3x + (x+5) + x = 40
Step-by-step explanation:
longest section 1 = a
mid length section 2 = b
shortest section 3 = x
P=40
a + b + x = P
a = 3x
b = x + 5
substitute for b & y
3x + (x+5) + x = 40
5x + 5 = 40
5x = 35
x = 7
b = 12
a = 21
Answer:
42.0 ft
Step-by-step explanation:
let t be the height of the tree.
<u><em>At the same time ,the measure of something </em></u>
<u><em>and its shadow are proportional</em></u> .
Then
Then
2t = 6 × 14
Then
2t = 84
Then
t = 84/2
Then
t = 42
Therefore the tree is 42 ft tall
