Answer:
Step-by-step explanation:
a: 2(-3x - 2)/2 = -3x - 2
c: -(6x +4)/2 = (-6x - 4)/2
d: -3x -2 when the brackets are removed and the terms are multiplied by -1/2
Answer:
x = 5, x = 
Step-by-step explanation:
Given
+
= 3 
= 
= 
=
( cross- multiply )
10(x² - 6x + 8) = 3(2x² - 10x + 10) ← distribute both sides
10x² - 60x + 80 = 6x² - 30x + 30 ← subtract 6x² - 30x + 30 from both sides
4x² - 30x + 50 = 0 ( divide through by 2 )
2x² - 15x + 25 = 0 ← in standard form
(2x - 5)(x - 5) = 0 ← in factored form
Equate each factor to zero and solve for x
2x - 5 = 0 ⇒ 2x = 5 ⇒ x = 
x - 5 = 0 ⇒ x = 5
Answer:
B. The statement does not make sense because 1 yen is worth approximately $0.0087
Step-by-step explanation:
Since $1 = ¥115 you can substitute ¥115 for $1 in the statement to see if it makes sense. (You can always substitute equals.)
Then you get ...
... so 1 yen is worth more than 115 yen. -- <em>a statement clearly false</em>
This means that for every inch there is 16 feet. 1 and 1/2 inches is also 1 + 1/4 + 1/4 inches, or (to scale) 16 + 4 + 4 feet, equaling 24 feet.
TL;DR 24 feet
