Answer:
6:3
Step-by-step explanation:
10 plus 5x = 50(x=8)
62 times 2x = 128(x=31)
Answer:
Step-by-step explanation:
a) 60 = 50x
x = 60 / 50 = 1.20
1.20(100) = 120%
b 50 = 60x
x = 50/60 = 0.83333....
0.83333(100) = 83.333... % or 83⅓%
Answer:
$6.25
Step-by-step explanation:
1. Variables
Let's the variable for socks will be s
2. Set up an equation
21.75 + 3s = 40.50
3. Subtract 21.75 from both sides
3s = 18.75
4. Divide 3 from both sides
s = $6.25
Presumably,

. In that case,
(A)
The average rate of change over the interval

is

and over

, it's

(B)

, i.e. the average rate of change over the second interval is 25 times higher. That's to be expected;

is an exponential function. As

gets larger, the rate of change of

gets larger too.
