Answer:
The ratio of red marbles to yellow marbles will be: 2 : 20 or 1 : 10
Step-by-step explanation:
As from the information
- The ratio of red marbles to blue marbles is 1 : 4.
- The ratio of blue marbles to yellow marbles is 2 : 5.
Multiply the ratio of red to blue marbles with 2.
1 : 4 = 1 × 2 : 4 × 2 = 2 : 8
Multiply the ratio of blue marbles to yellow marbles with 4.
2 : 5 = 2 × 4 : 5 × 4 = 8 : 20
Now the ratio of red : blue : yellow marbles will be:
2 : 8 : 20
Therefore, the ratio of red marbles to yellow marbles will be:
2 : 20 or 1 : 10

7 = n - 2
7 + 2 = n
9 = n
Therefore, n = 9
Answer:
1
0.8
0.4
Step-by-step explanation:
y = 5x
Substituting '5':
5 = 5x
x = 5/5
x = 1
Substituting 4:
4 = 5x
x = 4/5
x = 0.8
Substituting 2:
2 = 5x
x = 2/5
x = 0.4
the answer is CD m=y2-y1/x2-x1
m= 10-2/4-6= 8/-2=-4
If 2 segments are parallel they have 2 have same slope
Answer:
Step-by-step explanation:
Cyclic Quadrilateral's opposite angles add to 180
∠D + ∠B = 180
88 + x = 180
x = 180 - 88
x = 92°
