The solution is: x= 7 and y = 2
Step-by-step explanation:
Given equations are:
Putting x = 3y+1 in equation 2 from equation 1
Subtracting 1 from both sides
Dividing both sides by 7
Putting y=2 in equation 1
Hence,
The solution is: x= 7 and y = 2

Answer:
b. 10
Step-by-step explanation:
The triangles are all similar, so you have ...
hypotenuse/short side = x/4 = 25/x
Cross multiplying gives ...
x^2 = 100
x = 10 . . . . . . . take the square root
Answer:
x= 4.3125
Step-by-step explanation:
2^2 = 16x - 65
4= 16x- 65
+65 +65
69 = 16x
69/16 =16x/16
4.3125 = x
