Answer:
let ratio 4:5 be 4x& 5x
according to the question
5x=75
x=75/5=15
the number of Maths books=4x=4×5=20 is your answer
Let Sydney's age be x
Christine's age is 2x
Sum of their age is 54
x + 2x = 54
3x = 54
x = 18
Sydney is 18 years old.
The answer you’re looking for is x=145.
Every circle adds up to 360 degrees. The only measurement that we know is 70, but the congruent markings tell us that the unknown “sides” are the same. Therefore, you’d take 360-70=290. There are 290 degrees around the unknown part of the circle, which we then divide by 2 to get 145 degrees total. I hope this helped, let me know if I can explain anymore:)
The middle term of the simplified product is “x”.
The simplified product is x^2 - x - 12
X being the middle
hope this helps !
