The number of the blue cubes is 35 and the number of the red cubes is 20.
<h3>What is the ratio?</h3>
The ratio is defined as the representation of the one number with respect to the other number. or one number is how many times the other number.
Given that:-
- In a bag, there are red and blue cubes in the ratio of 4: 7
- I add 10 more red cubes to the bag. Now there are red and blue cubes in the ratio of 6: 7
The number of the blue cubes are calculated as:-
The two equations will be formed by the given data in the question.
7r = 4b
7r + 70 = 6b
Solving the above equation we will get the value of b.
4b + 70 = 6b
6b - 4b = 70
2b = 70
b = 35
7r = 4b
7r = 4 x 35
r = 20
Therefore the number of the blue cubes is 35 and the number of the red cubes is 20.

Answer:
50
Step-by-step explanation:
The interior angle next to 80 equals 100. all angles of a triangle should equal 180. 180-100 is 80, 80-30 is 50

Answer:
Slope: -1/4; Y-Intercept: 1.5
Step-by-step explanation:
Step 1: Find the slope. The best way to do this is to transform the two given points to y=mx+b form. When given two points, the best way to find the slope will be to do y2-y1/x2-x1. In this equation it would be -2-0/2+6, which is -2/8, simplified is -0.25 or -1/4. So we have the slope, which can determine the length of the line.
Step 2: Find the Y-Intercept. Finding the Y-intercept is so much simpler when given a graph, since all you have to do is find where the line goes through the y-axis, which in this case is (0,1.5), meaning that the y-intercept is 1.5 <em>(note: the y-intercept can also be found when x=0, for example (0,9).</em>

I think c it also could be b
