Answer:
False
Step-by-step explanation:
Here's a simple little trick to tell wether a system of inequalities has any solutions or not, just by looking at it:
- If the slopes are the same but the y-intercepts are different, the system has no solutions.
- If the slopes are different, the system has only one solution.
- If the slopes are the same and the y-intercepts are the same, then the system has infinitely many solutions.
By following this logic, since the system given has different slopes, it only has one solution. Therefore your answer is false.
Hope this helps you.

Roger: $24
Bethan: $36
Explanation:
4/5 of $75 is $60
So $60 is distributed to Roger and Bethan in the ratio 2 : 3.
Add the numbers in the ratio 2 : 3
2 + 3 = 5
Divide $60 by 5
60 ÷ 5 = 12
Multiply each number in the ratio 2 : 3 by 12:
2 • 12 : 3 • 12
= 24 : 36
I’m sorry if I explained this badly
But if my answer was correct, brainliest please!
Have a nice day!

Answer:
Red circle: 30 cm
Blue circle: 60 cm
Step-by-step explanation:
The circle's circumference is calculated with
They want you to make it <em>about</em> how long it is so instead of pi we can just use 3 (since pi is about 3,14). The diameter (d) is double the ratio.
So now we just put in the numbers.
For the red one
The circumference is about 30 centimetres.
For the blue one
We know the ratio of the smaller so we just add together the small ratio with the rest of the length that we know so the blue one's ratio is 10 cm. (5+5=10)
And now we just put the numbers in again.
The circumference is about 60 centimetres.
