Karolina [17]

As you know, 4.78 is less than 5, so
.. yes, x=4.78 is a solution to x < 5

As you know, 6 = 6, but is not less than 6.
.. no, x=6 is not a solution to x < 6.

CAN SOMEONE HELP WITH THIS ASAP!!!

Answer: x=8

Step-by-step explanation:

Since we are given that ∠ABC and ∠DBC are complementary angles, we know that adding them together should give us 90°. We can use this to solve for x.

6x+13+4x-3=90 [combine like terms]

10x+10=90 [subtract both sides by 10]

10x=80 [divide both sides by 10]

x=8

Now, we know that x=8.
