Answer:
2.5%
Step-by-step explanation:
interest = principal * rate * time
1200 = 8000r6
1200 = 48000r
r = 0.025
Rate for account is 2.5%
Answer:
Add 4 on both sides.
In the equation there is a -4.
If -4+4=0, that is how you would get rid of the -4.
But, you need to add 4 to 29 to really get rid of the -4.
So, 29+4 is 33.
b=33
Answer:
Step-by-step explanation:
a = 8 and b = -4 a(a - b) ÷ (a + b)
A) -12
B) 8/3
C) 10
D) 24
ANSWER IS D) 24
Solution
For this case we can do the following:
11y - 3x = 18
16y -3x = 33
We can multiply the first equation by -1 and we got:
-11y +3x =-18
16y -3x = 33
_______________
16y -11y = 33-18
5y = 15
y= 15/5 = 3
And then solving for x we got
x = -(18 -11*3)/ 3= -15/3 = 5
