(can prove using similarity of the triangle)
AC*CB = DC*CE
8*7 = 4*CE
CE = 14
DE = DC+CE = 4+14 = 18
Ans: 18
Answer:
D (3/2
Step-by-step explanation:
<u>Simplify both side of the equation</u>: 5(4x - 10) + 10x = 4(2x - 3) + 2(x - 4)
(5)(4x) + (5)(−10) + 10x = (4)(2x) + (4)(−3) + (2)(x) + (2)(−4)
Then you distribute: 20x + −50 + 10x = 8x + −12 + 2x + −8
(20x + 10x) + (−50) = (8x + 2x) + (−12 + −8)
Combine like terms: 30x + −50 = 10x + −20
30x - 50 = 10x - 20
<u>Subtract 10x from both sides</u>: 30x − 50 − 10x = 10x − 20 − 10x
20x - 50 = -20
<u>Add 50 to both sides</u>: 20x - 50 + 50 = -20 + 50
20x = 30
<u>Divide both sides by 20</u>: 20x / 20 = 30 / 20
<em>x = 3/2</em>

Boom! I hope that helped :)
It would be $636 because 30 times 22 is 660 and since it’s $4 interest for every hundred you do 6 times 4= 24 and 660-24=636.

Answer:
∠2 = 41°
Step-by-step explanation:
This is because, all three interior angles in a triangle will have a sum of 180 degrees.
So given that we have two angles, 90 degrees(right angle) and 49 degrees, we can replace angle 2 as our unknown value(a variable) and make it equal to 180 degrees then solve for x;
49 + 90 + x = 180
139 + x = 180
-139 -139
x = 41°, ∠2 = 41°
