Answer:
the answer is 7
Step-by-step explanation:
Add the same term to both sides of the equation
-x=7x-56
−x=7x−56
−x−7x=7x−56−7x
25% because the 0.25, the "25," are on the right hand side of the decimal point, that means they are 25 HUNDRETHS of a whole "one." key word: hundred. so therefore, it is 25%
Answer:
The correct option is (1).
Step-by-step explanation:
The given system of equation is,
..... (1)
.... (2)
The solution of the system of equation is the point where both line intersect each other.
Solve the equation by method of elimination.
Multiply equation 1 by 3.
... (3)
Add equation (2) and (3).
Put this value in equation 1.
Therefore, the lines intersect each other at (0.25,3.75). So, the first option is correct.
We know angles 3 and 4 = 123°. We also know that they are both located on a straight line, which is 180°. If we subtract 123 from 180, we get 57°, which is the size of the two angles in the smaller triangle KTL is located in.
Now, if we add up all the angles of a triangle, we get 180. With that knowledge, we can subtract 114° (57 x 2) from 180 and get out answer, which is 66°.
