Answer:

See explanation.

Step-by-step explanation:

An expression is a set of terms that are combined using addition, subtraction, multiplication, or division. The following are examples of expressions:

$2x-1$

$5y+8$

$2$

Note: expressions do not equal anything.

In contrast, equations are expressions that equal at least one term. The following are examples of equations:

$2y-4=26$

$4x-4=0$

$x=10$

$y=x+2$

Note: equations do equal a term, as shown in the examples.

Each basket in basketball is worth 2 points. Cathy makes 5 basketsand scores 6 more points with free throws. How many points did

statuscvo [17]

Since each basket in basketball is 2 points, then 2 * 5 = 10. If Cathy makes 6 more points from free throws, which are each one point, then you would have to do 10 + 6, which equals 16. So in total, Cathy scored a total of 16 points.
