Hello from MrBillDoesMath!
Answer:
Yes!
Discussion:
a + b= 2a => subtract "a" from both sides
a - a + b = 2a - a => as (a-a) = 0 and (2a-a) = a
b = a (*)
Then from (*) above
b-a = b - b => b-b = 0
b -a = 0
Thank you,

Answer: x= 5 years and y = $225
Step-by-step explanation:
Since we have given that
Amount Nisa gained per year = $25
Amount Kevin lost per year = $35
According to question,

so, it becomes,

so, For x= 5 years,
Their income of Nisa and loss of Kevin will be

Answer: 220
Step-by-step explanation: 130 degrees + the 90 degree angle = 220 degrees
Hope this helps:)
3.78 x 10^9 = 3780000000 = 3,780,000,000
3,780,000,000 / 14,000 = 270,000
270,000 = 2.7 x 10^5
The other factor would be (x + 4). We can find this by using synthetic division. To do this, we must first find the divisor, which would be 9, if we let x - 9 equal to zero and solve for x. Then, for the dividend, we can use the coefficients and constant term values.
<u>9</u>| 1 -5 -36
<u> 9 36</u>
1 4 0
Therefore, the other expression (x + 9) would be (x + 4). Hope this helped!
