Answer:
<h2>D</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about</h3>
first note: it will be more easy if we solve the inequality first
so let's solve it together




so what we get
we get that x is greater than 12
<h2>so the answer would be d</h2>
Answer:
there could be more than one answer...
Step-by-step explanation:
<u>k / 9 = 12</u>
Multiply each side of the equation by 9 : <em>k = 108</em>
<u>84 n = 504</u>
Divide each side of the equation by 84 : <em>n = 6</em>
<u>6 = m / 148</u>
Multiply each side of the equation by 148 : <em>888 = m</em>
Answer:
B
Step-by-step explanation:
Since ∠ E = ∠ F then the triangle is isosceles and DF = DE, that is
6x = x + 2y ( subtract x from both sides )
5x = 2y ( subtract 2y from both sides )
5x - 2y = 0 → (1)
and perimeter = 29, that is
6x x + 2y + 5x - y = 29 , simplifying
12x + y = 29 → (2)
Multiply (2) by 2
24x + 2y = 58 → (3)
Add (1) and (3) term by term to eliminate y, that is
29x = 58 ( divide both sides by 29 )
x = 2
Substitute x = 2 into (2) and evaluate for y
12(2) + y = 29
24 + y = 29 ( subtract 24 from both sides )
y = 5
Thus
FE = 5x - y = 5(2) - 5 = 10 - 5 = 5 → B
Answer: t= 13.4
Step-by-step explanation:
The given equation is 
To solve this equation for 't', we first divide both sides by
, we get

Taking log on both the sides, we get

Since 
Then,

Hence, the value of t is 13.4.
