Answer:
-The equation r+b-33 represents the total number of marbles
-There 9 black marbles
-There are 24 red marbles
Step-by-step explanation:
The bag contains 33 red and black marbles. Let the number of black marbles be b and that of red marble to r
Total number of marbles will be
b+r = 33 i.e b+r-33 = 0... (1)
If the number of red marbles is 6 more than double the number of black marbles, this can be represented as;
r = 6+ 2b... (2)
Substituting 2 in eqn 1 we have;
b + 6+2b = 33
3b = 27
b = 9
r = 33-9
r = 24
This shows that there are 9 black marbles, 24 red marbles and the equation r+b-33 represents the total number of marbles in the bag.
First, you calculate 10% of 2500, which is 250. Then, you multiple it by five because she borrowed it for FIVE years. The answer is C. :)
Answer:
0.009 also as 0 and 9 thousandths
Step-by-step explanation:
Answer:
i) p = 4
ii) p = 8
iii) p = 12
Step-by-step explanation:
Here, we need to understand the initial relation
Mathematically, we have this as;
2.79 * p = c
So let us calculate the value of p for each value of c
i) 2.79p = 11.16
p = 11.16/2.79
p = 4
ii) 2.79p = 22.32
p = 22.32/2.79
p = 8
iii) 2.79p = 33.48
p = 33.48/2.79 = 12
