Answer: A) 3x + 5x - 4 = 1
<u>Step-by-step explanation:</u>
The second equation is y + 4 = 5x. Solve this equation for y by subtracting 4 from both sides. --> y = 5x - 4
Now replace "y" in the first equation with "5x - 4".
3x + y = 1
--> 3x + (5x - 4) = 1
hola buenos días tío PEDRO de la Mari pero le

Answer:
25
Step-by-step explanation:
To find the missing side (in this case, the longest one/hypotenuse), we can use the equation a^2 + b^2 = c^2. By substituting out the variables, we get 7^2 + 24^2 = c^2; this can be simplified to 49 + 576 = c^2. Add, and then we know that 625 = c^2. If c squared is 625, we need to find the square root of 625, which is 25.
Answer:
x=70 angle b = 70 and angle c=72
Step-by-step explanation:
all triangles add up to 180 so the equation is 2x+40=180
