Answer:
$60
Step-by-step explanation:
Let x represent the initial money she had
She spent 3/5 of her money on a bag, That is;
3/5 of x
= 3/5 * x
and 1/6 of x on a belt
Therefore, the total money she spent is
3/5 * x + 1/6 * x
She had $14 left after all her purchases
To find how much she had left, sum up all her spending and what she has left
3/5 * x + 1/6 * x + 14 = x
collect like terms
3/5 x + 1/6 x - x = -14
23/30 x -x = -14
-7/30x = -14
x = $60
Answer:
The average rate of change for the given function, from x = −3 to x = 7 will be:
Step-by-step explanation:
Given the table
x f(x)
-3 50
3 10
7 0
As the interval is from x = -3 to x = 7.
so
at x₁ = -3, f(x₁) = 50
at x₂ = 7, f(x₂) = 0
Using the formula to determine the average rate of change at which the total cost increases will be:
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [0 - 50] / [7-(-3)]
= [-50] / [7+3]
= -50 / 10
= -5
Therefore, the average rate of change for the given function, from x = −3 to x = 7 will be:
Answer:
0.03 = 3%
0.18 = 18%
23/25 = 92%
Step-by-step explanation:
D, the answer is the same but in the parenthesis is reversed using the addiction something property
Answer:
8 dollars
Step-by-step explanation:
if "x" is his weekly allowance:
x-0.5x+8=12
Dan make x dollars, then he spend 0.5x dollars and he earned 8 dollars, and that is 12 dollars.
0.5x=12-8
x=8 dollars
