Answer:
see explanation
Step-by-step explanation:
The restriction a ≠ 0 and b ≠ 0 is applied since division by zero would make
and its reciprocal undefined, thus meaningless
No.
5a-9=26 add 6 to both sides, 5a=35 Divide by 5, a=7 not 5.

Answer:
The monthly payments $193.33.
The total interest for the loan $1,599.8.
Step-by-step explanation:
Given formula:
= (PMT×nt)-P
PMT= Monthly installment
P= Present value
r= Rate of interest
t= Time
n= Number of interest per year.
Here,
P=$10,000, r= 6%=0.06, t= 5 years, n=12
= (PMT×nt)-P
=(193.33×12×5)-10,000
=11,599.8 -10,000
=$1,599.8
The monthly payments $193.33.
The total interest for the loan $1,599.8.
Answer:
(E) 450
Step-by-step explanation:
Let x represent the number of gallons of solution X that must be added to the mix. Then the amount of sugar in the mix is ...
0.20x +0.40·150 = 0.25(150 +x)
0.20x +60 = 37.5 +0.25x . . . eliminate parentheses
22.5 + 0.20x = 0.25x . . . . . . subtract 37.5
22.5 = 0.05x . . . . . . . . . . . . . subtract 0.20x
450 = x . . . . . . . . . . . . . . . . . . multiply by 20
450 gallons of solution X must be added to make a 25% sugar solution.
