We have the expression:

And want to evaluate in y=5, this means we have to replace y in the expression for 5 and calculate the value of the expression, so:

The expression is 30 when y=5.
Answer:
x = 50°
Step-by-step explanation:
sum of all angles of a quadrilateral is 360°
so, the other unknown angle be y
=》y + 40° + 110° + 80° = 360°
=》y + 230° = 360°
=》y = 360° - 230° = 130°
and the unknown angle + x = 180°
( because they for linear pair )
so, x + y = 180°
x + 130° = 180°
x = 180° - 130° = 50°
hence, x = 50°
Answer:
D. decreases the demand for money.
Step-by-step explanation:
Money demand and interest rate has an inverse relationship.
An increase in the interest rate decreases the demand for money. An increase in the price of bonds results in a lower interest rate.
When the interest rate increases, an individual's opportunity cost for holding his money increases. In this condition, the person chooses to hold more bonds, thereby demanding less money.
