Answer: he would have $343.47 after 2 years.
Step-by-step explanation:
if he leaves his interest from the first year in the bank, we would assume that his interest was compounded. We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = $300
r = 7% = 7/100 = 0.07
n = 1 because it was compounded once in a year.
t = 2 years
Therefore,.
A = 300(1 + 0.07/1)^1 × 2
A = 300(1.07)^2
A = $343.47
Alana and Petra bought 9 books combined.
Angus bought 19 books and had a $10 discount.
Angus spent $5 more than Alana and Petra combined.
This means that the price of 19 books is $15 more than the price of 9 books. 19 books is 10 books more than 9 books.
Giving you 10 books = $15, 1 book = $1.50
Answer:
y = 4
x= 7
Step-by-step explanation:
First you would rearrange the first equation x-7y=-21 and make x the subject:
x= -21 +7y
Then substitute x into the 2nd equation to find y:
13x - 7y= 63
13(-21+7y) - 7y = 63
-273 + 91y -7y = 63
-273 + 84y=63
84y = 63 + 273
84y = 336
y = 4
Once you have y you can substitute this into any of the original equations to find x, for example:
x - 7y = -21
x - 7(4) = -21
x - 28 = -21
x = -21 +28
x= 7
Answer:
There will be three digits in the quotient.
Step-by-step explanation:
The answer would be 119. Hope this helped ^^✨
(1)4x + 3> 15 or -6x>=12
4x+3>15, subtract 3 on both sides (4x> 12) and then divide both sides by 4
x > 3
-6x>=12, divide both sides by -6 , so x<=-2
x>3 or x<=-2
The middle graph satisfies the above inequality
(2) -8x>-24 and -10<=2x-6
-8x>-24 , divide both sides by -8 , so it becomes x < 3
-10<=2x-6, add both sides by 6 , -4<=2x . then divide both sides by 2
x >=-2
x>-2 and x<3
The last graph satisfies the above inequality
-29<=9x-2<16
Add both sides by 2 and then divide both sides by 9
-27 <= 9x < 18
divide both sides by 9
-3 <= x < 2
x lies between -3 and 2
The first graph satisfies the above inequality
