Answer:
i think it has 4
Step-by-step explanation:
t + 15 is something on money
First solve the equation for 3x
-3x+3y=12
3x=-57-6y
Now substitute the given value into the equation
-(-57-6y)+3y=12
Then solve for y
Y=-5
Then substitute the given value of y
3x=-57-6✖️(-5)
Now solve for x
X=-9
Ordered pairs
(X,Y)=(-9,-5)
Then you are left with your answer:
(-9,-5)
Hope this helps! :3

Answer:
Number of whole tiles need = 120,000 tiles
Step-by-step explanation:
Given:
Area of room = 300 m²
Dimension of each tile = 5cm x 5cm
Find:
Number of whole tiles need
Computation:
Dimension of tile in meter = 5 /100 = 0.05 m
Area of each tile = 0.05 x 0.05
Area of each tile = 0.0025 m²
Number of whole tiles need = Area of room / Area of each tile
Number of whole tiles need = 300 / 0.0025
Number of whole tiles need = 120,000 tiles
Total 120,000 tiles need to cover 300 m² room.
