X=-2y+1. and 3x+8y=11

x=-7

y=4

Step-by-step explanation:

I am assuming you want the values of x and y. We know that x=-2y+1 and 3x+8y=11. We can substitute the value of x (-2y+1) into the equation 3x+8y=11.

Therefore 3(-2y+1)+8y=11

Using the distributive property:

-6y+3+8y=11

2y+3=11

y=4

To solve for x, we will plug in 4 in -2y+1. So, x= -2(4)+1=-7.

Check: 3(-7)+8(4)=-21+32=11.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
