Answer:
10
Step-by-step explanation:
x = Edith's age = 20 years
y = Ronald's age
x = 20 = y/4
y = 20×4 = 80 years
in z years we have
(x + z) = (y + z)/3
(20 + z) = (80 + z)/3
3(20 + z) = 80 + z
60 + 3z = 80 + z
60 + 2z = 80
2z = 20
z = 10
in 10 years Edith's age will be 1/3 of Ronald's age.
then Edith will be 30, and Ronald will be 90.
30 = 90/3
correct.
Answer:
C(2, 2) is the solution to both lines A and B.
Step-by-step explanation:
Line A is given as:
A straight line labeled A joins the ordered pair 3, 0 and the ordered pair 0, 6.
We know that the equation of a line passing through (a,b) and (c,d) is calculated as:
Hence, the equation of line is:
Hence, equation of line A is:
Similarly B is a line passing through (0,0) and (5,5).
Hence, the equation of line B is:
So, from the graph we observe that, the point of intersection of the two lines is (2,2).
Thus, option C is correct.
The first question I think it’s A because 1.13 is larger than 1.2
I hope this helps
