Answer:
x = 3
Step-by-step explanation:
set up proportion based on corresponding sides of similar triangles:
15 / 10 = 15 + x / 12
cross-multiply:
10(15 + x) = 15(12)
150 + 10x = 180
10x = 30
x = 3
Answer:7 x -6
Step-by-step explanation: 7 x -6= -42
7 + -6= 1
becasue different signs subtract and keep the sign of the bigger number since the 7 is positive and 6 is negative u subtrac and 7 is bigger than 6 so the answer is gonna be positive. Hope this was helpful <3
Answer:
cost of journey of 25 miles = £ 17.5
Step-by-step explanation:
Base on the equation the cost of the journey can be represented as
C = 0.5n + 5
where
C = cost in £
n = number miles covered
To calculate the cost of a journey that is 25 miles we have to insert the value of n as 25 in the equation. Therefore,
C = 0.5n + 5
n = 25
C = 0.5(25) + 5
C = 12.5 + 5
C = £ 17.5
cost of journey of 25 miles = £ 17.5
I was thinking it would be 125° because of alternate exterior angles but i’m not super sure but if i’m wrong i’m sorry!
If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.
