Step-by-step explanation:
(a)
The 2 colours are yellow and blue
yellow : blue = 14 : 24 ( divide both parts by 2 )
= 7 : 12 , or
(b)
The number of red snacks = 13 per 100
Then number of red for 500 = 13 × 5 = 65 ( 500 is 5 times greater than 100 )
Homework = 12.5% of 24 hours = 0.125 x 24 = 3 hours
Sam spent <u>3 hours</u> on homework.
Proportion of the time spent on homework = 3/24 = 1/8
Answer: Same spent 1/8 of his day on homework.
It’s b because I just did that question
Since both equations equal y they need to equal each other.
2x - 5 = -3x + 10
Add 3x to both sides:
5x -5 = 10
Add 5 to both sides
5x = 15
Divide both sides by 5
X = 3
Now solve for y by replacing x with 3:
Y = 2(3)-5 = 6-5 = 1
Y = -3(3)+ 10 = -9+ 10 = 1
Check: replace y with 1 and solve for x:
1 = 2x -5
Add 5 to both sides
6 = 2x
Divide both sides by 2
X = 3 ( True)
