6 days
Y= 107-8x
Y=83-4x
You can use substitution
83-4X= 107-8x
Bring 8X
Over to the left
83+ 4x=107
Subtract 83
4x= 24
X=6
Or put in calculator and go 2nd graph you see table and on 6 day they both have $59
Answer: 8.16•10^2
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
. The sign of the exponent will depend on the direction you are moving the decimal. You do this to both equations and when you got the final answer of you divide the 2 equations and put it back in scientific notation Mark me brainliest
Answer:
-8n + 9
Step-by-step explanation:
Given that,
A = -3n + 2
B = 5n - 7
Before solving you have to know that,
( + ) × ( + ) = ( + )
( - ) × ( - ) = ( + )
( + ) × ( - ) = ( - )
Let us solve now.
A - B
-3n + 2 -(5n - 7)
-3n + 2 - 5n + 7
Combine like terms
-3n - 5n + 2 + 7
-8n + 9
Hope this helps you.
