Answer:
The amount that William has at the beginning is $37.50 and the amount that Gracie has at the beginning is $52.50
Step-by-step explanation:
Let
x ---> amount that William has at the beginning
y ---> amount that Gracie has at the beginning
we know that
William says to Gracie, "If you give me $7.50,we will have and equal amount of money
so
----> equation A
"Grace responds, if you give me $ 7.50 instead, I will have twice as much money as you
----> equation B
substitute equation A in equation B
solve for x
Find the value of y
therefore
The amount that William has at the beginning is $37.50 and the amount that Gracie has at the beginning is $52.50

Answer:
c ≈ 5.5 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
c² = 2.4² + 4.9² = 5.76 + 24.01 = 29.77 ( take square root of both sides )
c = 
≈ 5.5 cm ( to the nearest tenth )
To find a number in between you could multiply 39/130 by 2/2
and 40/130 by 2/2 to get
78/260 and 80/260
Answer:
1/2 is equivalent to 50%
Step-by-step explanation:
In order to convert a fraction to a percentage you divide the numerator (Top number of a fraction) by the denominator (Bottom number of a fraction), multiply by 100, and add a percentage sign.
So lets try that with our first answer option A) 1/2:
1 divided by 2 = 0.5
0.5 x 100 = 50
50%
So we know that 1/2 is equivalent to 50%
