Answer: 21
Step-by-step explanation: All he did was took the amount of red and gave it a ratio of 7:1 meaning that he will increase the amount of red and make it 21 because the number 8 increased by 3 so 7 must increase by 3 as well.
Answer:
15
Step-by-step explanation:
We assume you mean that ...
∠1 + ∠2 = 90°
60° + 2x° = 90° . . . . given values for the angles
2x° = 30° . . . . . . . . . .subtract 60°
x = 15
X= 1.25. I hope this helps you
Answer:
4 1/3
Step-by-step explanation:
Find slope (y2-y1)/(x2-x1)
Pick any two points on line
(1,15) and (2,25)
(25-15)/(2-1) = 10/1, slope is 10 (rate of change)
Y = 10x + b
15 = 10 + b
The y intercept would be 5
