I think it’s C sorry if it’s wrong
5r + 6s = 53
25r + 3s = 49
Meaning of simultaneous is to solve by elimination
Multiply the equation 2 by -2
-2( 25r + 3s = 49)
-50r – 6s = -98
Then add the two equation to eliminate s, so the resulting equation is:
-45r =-45
r = 1
substitute r = 1 to equation 1
5(1) + 6s = 53
6s = 53 – 5
6s = 48

Answer:
Im sorry! idk the answer but if you have a phone, there is this app called photo math, or ask you mom or dad for help.
Step-by-step explanation:
Answer:
-1<x<1 and 1<x
Step-by-step explanation:
We are asked to determine the interval in which our function shown in the graph has positive values.
In order to do so, we have to see for what values of x on x axis, the graph is above x axis.
As we can see in the graph, when we move from x = -1 towards right, the graph is above x axis. And towards left of x=-1 , the graph is below x axis. Hence answer is
-1<x<1 and 1<x
64% = $389
___ ____
100% X$ = Cross multiplication. (64x = 38900 = $607.81)
I rounded it.
Hope I become the brainliest answer.
