First, move all terms containing a to the left, all other terms to the right.
Add '2b' to each side of the equation.4a + -2b + 2b = 16 + 2b
Combine like terms: -2b + 2b = 04a + 0 = 16 + 2b4a = 16 + 2b
Divide each side by '4'.a = 4 + 0.5b
Answer
= 4 + 0.5b
Happy studying ^-^
Answer:
d, To undo addition, you can use multiplication
Step-by-step explanation:
a, To remove a whole number next to the variable, multiply both sides by that number
Idk what it means, sorry and good luck
Use compound interest formula F=P(1+i)^n twice, one for each deposit and sum the two results.
For the P=$40,000 deposit,
i=10%/2=5% (semi-annual)
number of periods (6 months), n = 6*2 = 12
Future value (at end of year 6),
F = P(1+i)^n = 40,000(1+0.05)^12 = $71834.253
For the P=20000, deposited at the START of the fourth year, which is the same as the end of the third year.
i=5% (semi-annual
n=2*(6-3), n = 6
Future value (at end of year 6)
F=P(1+i)^n = 20000(1+0.05)^6 = 26801.913
Total amount after 6 years
= 71834.253 + 26801.913
=98636.17 (to the nearest cent.)
Y>3 is the correct answer because more than 3 inches of rain fell.
