Answer:
the answer is B (2,1)
Step-by-step explanation:
Given the simultaneous equation
Using substitution method
from equation 2 :
Substitute equation 3 into 1:
Open the bracket
Substitute y=1 into x=3-y
Hence the solution to the equation is (2,1)

C is the answer
x+y<57
50.000x+100.000y>3.000.000
Answer:
$300
Step-by-step explanation:
Since 20% is equal to 1/5, you should multiply $60 by 5 to get $300 as the original cost and as your answer.
Answer:
Below.
Step-by-step explanation:
As both the right sides of the 2 equations are equal to y, by the transitive law of equality 3x + 1 = -2x + 3.
W then solve this equation for x then substitute this value of x in the first equation ( y = 3x + 1) to find the value of y.
Distance (in miles) Amount of fuel (in gallons)
1092 109
671 67
985 99
Relation, x/y = 1092/109 = 10.02
671/67 = 10.2
So, Relation is x = 10.02y
Hope this helps!
