It will take her 8 weeks to have enough money for a bike. I made the equation 125+15x=245 and multiplied 15 by 8 to get exactly 245
Times means
2 times 3 means 3+3
4 times of 3=3+3+3+3
divide is
4 divided into 2 parts=2
6 divided into 3 parts=3
but you could multiply by a fraction and essensially divide
they are different
Written as a unit rate would be 5 dollars for each pounds.
I hope this helps!
The right triangle has legs of x and 2.5 where x is the height up the wall that the ladder will reach. The length of the ladder is the hypotenuse of the right triangle.
According to the Pythagorean Theorem, x^2 + 2.5^2 = 12^2
x = 11.736 approx To the nearest tenth that is 11.7.
