If it says 3×8 its like saying 8+8+8=21.
It's just a faster way of adding.
Anything multiplied by 0 is 0.
Anything multiplied by 10 just add a 0 to the end of the number example 10×2=20.
Answer:
or 9
Step-by-step explanation:
1. Set up the problem: 
÷ 
2. Replace the division sign with a multiplication sign: ×
3. Find the reciprocal by swapping the numerator and denominator on the second fraction: × 
4. Multiply fractions: × = or 9
Answer:
Step-by-step explanation:
Remember that the center of a circle is written in (h,k) format. So h= - 9 and k = -12. Also, the distance between those two points is 15 units, so r = 15.
So the formula 
Should look like
<u><em>The total number of red counters that are in the box is; 728 red counters</em></u>
- We are told that the box contains 1079 counters.
Let the number of white counters be x.
Let the number of red counters be y.
Let the number of black counters be z.
Thus;
z:x = 2:7
Thus; 2x/7 = z
Also, we are given;
x:y = 3:8
Thus;
8x/3 = y
- Since total number in the box is 1079,then;
x + y + z = 1079
x + (8x/3) + (2x/7) = 1079
Multiply through by 21 to get;
21x + 56x + 6x = 22659
83x = 22659
x = 22659/83
x = 273
2x/7 = z
Thus; z = 2 × 273/7
z = 78
8x/3 = y
y = 8 × 273/3
y = 728
273 white counters
728 red counters
78 black counters.
