3(a+b) and 3a+b: not equivalent
4(x+2y) and 8y+4x: equivalent
Let the amount invested at 4% be = x
Let the amount invested at 3% be = y
Given is:
or .... (1)
As, total income for the two investments is $194, so equation is:
....(2)
Putting value of x from (1) in (2)
And x=5200-y
Hence, money invested at 4% is $3800 and money invested at 3% is $1400
Answer:

<u>Step-by-step explanation:</u>
Here we have , John kept track of how many baskets were made in a basketball game. After 4 minutes, 5 baskets were made. We need to find How many baskets were made between 9 and 10 minutes . Let's find out:
In order to calculate baskets between 9 min and 10 min we will find baskets at 10 min and at at 9 min , will subtract than !
Baskets at 10 min :
At 4 min we have 5 baskets so , in 10 min
⇒
⇒
⇒
Baskets at 9 min :
At 4 min we have 5 baskets so , in 9 min
⇒
⇒
⇒
So , Baskets between 10 & 9 min is , which on rounding off gives 1 . Therefore , 1 basket is between 9 and 10 minutes .
Just add the numbers in without the dollar sign in front. Have one axis as money and the other as amount then add in the data.
