Answer:
y
Step-by-step explanation:
A constant in an equation for example the equation 3x-7=5, the constant would be 7 and 5, the coefficient would be 3, the variable would be x and lastly, the subtraction sign would be the operator. So the answer would be y.
Answer:
7 marble's
Step-by-step explanation:
55 marbles and twice as many white marbles as red marbles and he has 5 more blue marbles than white marble's
We are given that:
side length = 8 3/2 inches = 9.5 inches
the rule for the area is: A = s^2
Substitute with the side length in the rule given to get the area as follows:
Area = s^2 = (9.5)^2 = 90.25 inch^2
20 is the answer to this problem
Cosine(angle) = adjacent leg/ hypotenuse
Cosine( angle ) = 18/20
Angle = arccos(18/20)
Angle = 26 degrees
