Answer: The expression represents the price of a sandwich.
Step-by-step explanation:
The given statement : The price of a sandwich is $1.50 more than the price of a smoothie,which is d dollars.
We know that in a algebraic expression , we use Addition sign (+) to show " more than".
Therefore, the given expression: actually represents the price of a sandwich.
Hence, the expression represents the price of a sandwich.

Answer:
i. <DCB =
ii. Sin of <DCB = 0.8
Step-by-step explanation:
Let <DCB be represented by θ, so that;
Sin θ =
Thus from the given diagram, we have;
Sin θ =
= 0.8
This implies that,
θ = 0.8
= 53.1301
θ =
Therefore, <DCB = .
So that,
Sin of <DCB = Sin
= 0.8
Sin of <DCB = 0.8
Answer:
A
Step-by-step explanation:
all we need to do is to plug the point (6,4) in the inequality and see if it satisfies it :
pay attention that here we have x=6 y=4
4<
we simplify we get :
4<4.5-3
4<1.5 which is incorrect so (6,4) is not a solution. moreover
notice that 4 is > than 1.5 so the point lies above the line
thus the answer is : A
you can also solve this problem by graphing the line and plotting the point (6,4) and hence you will notice that the point is above the line
