X+2y = 9 ---------eq.1
x-y =6 ----------- eq.2

x = 9 -2y (from eq. 1)

Now substitute the value of x in the second eq.2

9-2y-y =6
-3y = -3
y =1

So,
x +2 (1)= 9
x= 7

Answer:

The answer is "\frac{1}{25}"

Step-by-step explanation:

They might claim that perhaps the ratio to Raul would've been:\frac{y}{x} = \frac{5}{125} = \frac{1}{25} per each 125(x) page, which he reviewed throughout a summer competition.

Raul's cost per unit for each paragraph reads is \frac{1}{25} page points, that's why the model a link with the same unit rate. please find the graph in the attached file.

Answer:

c = 5

Step-by-step explanation:

a^2 + b^2 = c^2

3^2 + 4^2 = c^2

9 + 16 = 25

c^2 = 25

sqrt of 25 = 5

c= 5
