Step-by-step explanation:
No of pieces John has = 240
No of pieces Stephen has = twice of Johns sweet = 240 x 2 = 480
No of pieces John Sister has = half of John's sweet = 240 ÷ 2 = 120
Total sweets = 240 + 480 + 120 = 840

Answer:
3/13
Step-by-step explanation:
ratio is another way to say fraction, so we have 21/91. This can be reduced if we divide by 7: 21/7 = 3, 91/7 = 13. Now we have 3/13. You can write it as 3:13 or 3/13.
The equation is y= -5/2x + (-10)
To find the y-intercept you use the equation.
y= -5/2x + b
You substitute y with the y value which is 5 and x with the x value which is -6. You multiply -5/2 by -6 which gives us 30/2 which equals to 15. Then you subtract 15.
5= -5/2(-6) + b
5-15 = 15 - 15
b= -10
The slope is -5/2 and the y-intercept is -10
So the equation of the line is y= -5/2x + (-10)
