I suck at algebra but my advice is download photomath it will help trust me
Answer:
9, -3
Step-by-step explanation:
An algebraic expression is a phrase in mathematics that consists of numbers such as 1,2,3 and the like, variables which are represented with letters and operations like addition, multiplication, subtraction and division. It is usually used to represent a certain situation which would relate the variables involved. To write the algebraic expression for the problem statement above, we do as follows:
Let x = number of consoles to be bought
y = number of games to be bought
z = number of controllers to bebought
C = total cost of all
The total cost would be equal to the sum of the price multiplied by the number of consoles, games and controllers bought. We write the algebraic expression as follows,
C = 299x + 59.99y + 29.99z
I think is B sorry if I am worng
Step-by-step explanation:
the equations are :-
=》d = 40m + 200
=》d = 50m
here, by equalising both equations.
( since, d = d )
=》40m + 200 = 50m
=》50m - 40m = 200
=》10m = 200
=》m = 200 ÷ 10
=》m = 20
now,
=》d = 50m
=》d = 50 × 20
=》d = 1000
