The first statement means:
b=i+12,
The third statement means:
b-3=4(i-3),
b-3=4i-12
b=4i-9
Using the value for b from the first statement in the third statement gives you:
i+12=4i-9
-3i=-21
i=7: and since b=i+12
b=19
So Ben is 19 and Ishaan is 7.
The answer is 4/7. see it from the multiple of 3...3*4 =12 and 3*7= 21. So this is the answer: 4/7.
Answer:
First account= 2500
Second account= 4000
Step-by-step explanation:
Total amount invested: 6500
Amount in first account: x
Amount in second account: y
x+y=6500
1.13x+0.9y=6500-75=6425
You have two equation now just solve the system of equation through either substitution or elimination.
Then you'll get the answer
x= 2500
y= 4000
8r + 7 - 6r -5
2r + 7 - 5
2r + 2
