5 1/4 in decimal form is 5.25 because 25 is 1/4 of 100.
Best to write these two figures in a column:
$5672
-$4523
-----------
$ 1149 is the amount you have left.
The quadratic model is f(x) = -5x^2 + 200.
f(x) = 50 meters
x = time in seconds
50 = -5x^2 + 200
5x^2 = 150 // Here, divide both side by 5
x^2 = 30
x =
seconds
Or approximately 5.48 seconds
Answer:
Keisha =$25
Scott =$19
Ryan = $57
Step-by-step explanation:
Let the amount each have be represented by A, B and C
Keisha = A
Scott = B
Ryan = C
Keisha , Scott and Ryan have a total of $101.
That’s
A + B + C = $101
Keisha has $6 more than Scott
A = 6 + B
Ryan has 3 times Scott
C = 3B
Substitute 6+B for A and 3B for C in the first equation.
That’s
A + B + C = 101
6 + B + B + 3B = 101
6 + 5B = 101
Subtract 6 from both sides
6 - 6 + 5B = 101 - 6
5B = 95
Divide both sides by 5
B = 95/5
B = 19
Scott has $19
Recall Keisha has $6 more than Scott B.
That’s A = 6 + B
A = $6 + $19
A = $25
Keisha has $25
Also, Ryan C has 3 times what Scott B has .
That’s
C = 3 x B
C = 3 x 19
C = $57
Therefore, Keisha has $25, Scott has $19 and Ryan has $57
