Determine whether the ordered pair (10, 4) is solution to the equation 3x - 5y = 10 O Yes, (10, 4) is a solution.
O No, (10, 4) is not a solution.

Given :

The ordered pair (10, 4) is solution to the equation 3x - 5y = 10.

To Find :

Which one is the solution and which is not.

Solution :

Two pairs are (10,4) and (4,10) :

Putting ( 10,4 ) in given equation, we get :

LHS = 3( 10 ) - 5( 4 ) = 30 - 20 = 10 = RHS

So, ( 10,4 ) is the solution of the equation.

Now, putting, ( 4, 10 ) in given equation, we get :

LHS = 3( 4 ) - 5( 10 ) = 12 - 50 = -38 ≠ RHS

Therefore, (10,4) is the solution and (4,10 ) is not the solution.

Hence, this is the required solution.

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
