Answer:
114 marbles.
Step-by-step explanation:
Let the number of red marbles be r
Let the number of black marbles be b
<u>Given the following data;</u>
Total number of marbles = 120
Translating the word problem into an algebraic equation, we have;
.......equation 1
........equation 2
Substituting the value of "r" into equation 2, we have;



b = 6 marbles.
To find the number of red marbles;
From equation 1;
Substituting the value of "b" into equation 1, we have;

<em>r = 114 marbles.</em>
<em>Therefore, there are 114 red marbles in the bag. </em>
Answer: 313
Step-by-step explanation:
Let x be the attendance before the drop.
Given: An article reports, "attendance dropped 4% this year, to 300.
Wec can write 4% = 0.04
Then, 4% of x = 0.04x
Now according to the question we have:-
![x-0.04x=300\\\\\Rightarrow\ x(1-0.04)=300\\\\\Rightarrow\ 0.96x=300\\\\\Rightarrow\ x=\dfrac{300}{0.96}=312.5\approx313\ \ \ \ \text{[Rounded to the nearest whole numbers.]}](https://tex.z-dn.net/?f=x-0.04x%3D300%5C%5C%5C%5C%5CRightarrow%5C%20x%281-0.04%29%3D300%5C%5C%5C%5C%5CRightarrow%5C%200.96x%3D300%5C%5C%5C%5C%5CRightarrow%5C%20x%3D%5Cdfrac%7B300%7D%7B0.96%7D%3D312.5%5Capprox313%5C%20%5C%20%5C%20%5C%20%5Ctext%7B%5BRounded%20to%20the%20nearest%20whole%20numbers.%5D%7D)
Hence, the the attendance before the drop = 313
Answer:
6 Hours
Step-by-step explanation:
360 is half of 720, so it would take half the time to travel. half of 12 is 6
