Please help I need the answer fast I’m so confused

Answer 1

Hello!

Answer:

`\Large \boxed{\sf x = 5}`

`\Large \boxed{\sf JK = 80}`

Explanation:

→ We want to find the value of x and JK.

Find the value of x:

→ We know that JM is equal to MK.

→ So we have this equation:

`\sf 7x+5=8x`

→ Let's solve this equation to find x:

◼ Subtract 7x from both sides:

`\sf 7x+5-7x=8x-7x`

◼ Simplify both sides:

`\boxed{\sf x = 5}`

Find the value of JK:

→ We know that JK is equal to JM + MK.

→ So we have this equation:

`\sf JK = 7x+5+8x`

→ Let's replace x by 5 to find JK:

`\sf JK = 7 * 5 + 5 + 8 * 5`

→ Simplify the equation:

`\sf JK = 35 + 5 + 40`

`\boxed{\sf JK = 80}`

Conclusion:

x is equal to 5, so JK is equal to 80.
