18 + 0.14m = 8 + 0.19m
18 - 8 = 0.19m - 0.14m
10 = 0.05m
10 / 0.05 = m
200 = m <== they will cost the same at 200 minutes
7:9
42:54
7 · 6 = 42
9 · 6 = 54
That means: 7:9 = 42:54
Yes.It can form a proportion.
Hope this helps :)
Answer:
y = 2x - 8
Step-by-step explanation:
The charity should collect 600 cans of food
Number of families that the charity asked to donate food = 150
80% of the families donated 5 cans of food
Number of families that actually donated 5 cans of food = (80/100) x 150
Number of families that actually donated 5 cans of food = 0.8 x 150
Number of families that actually donated 5 cans of food = 120
Number of cans donated by each family = 5
Number of cans donated by 120 families = 5 x 120
Number of cans donated by 120 families = 600
The charity should collect 600 cans of food

Answer:
Step-by-step explanation:
Here, we want to write the equations in the form of matrix
To do this we simply make sure that the coefficients of any given variable are on the same side of the matrix to first form a 2 by 2 matrix
Then we proceed to use the variables to form a 1 by 1 matrix by side and then finally the results forming another 1 by 1 matrix by the side
