To determine the answer, we need to set up equations. We do this by doing mass balances. We let
x = A alloy 25% copper
y = B alloy 55% copper
Overall Mass balance:
x + y = 100
Copper mass balance:
.25x + .55y = .43(100) = 43
SOlving simultaneously, we get:
x = 99.67 kg 25% copper alloy
y = 0.33 kg 55% copper alloy
Answer:
-26
Step-by-step explanation:
x-39=-65
+39 +39
x= -65+39
x= -26
I get it I've been there lol
Hope this helps! :)
Answer:
x ≈ 11.09
Step-by-step explanation:
Using the rule of logarithms
x = n ⇒ x = 
Given
ln(x + 9) = 3 , that is
(x + 9) = 3 , then
x + 9 = e³ ( subtract 9 from both sides )
x = e³ - 9 ≈ 11.09 ( to the nearest hundredth )
