Answer:
24 inches.
Step-by-step explanation:
Add em' all up cuz.
4(a-2)=3(a+4)
4a-8=3a+12
a=20
60% decrease.
$105-$42 = $63
$63/$105 = 0.6
0.6 x 100 = 60
X + y = 1.....multiply by -2
2x - 3y = -30
-----------------
-2x - 2y = -2 (result of multiplying by -2)
2x - 3y = -30
----------------add
-5y = -32
y = -32/-5
y = 32/5 or 6.4 <===
Distribute the 8p to all of the numbers in the parenthesis. You would multiply the coefficient and add the exponents. The answer would be B.
