Answer:
Ava's share = $20
Charlotte's share = $16
Step-by-step explanation:
15x + 12x = 36 : multiply each girl's age by same amount and adding gives $36
27x = 36 : add x terms
x = 36 / 27 : divide both sides of equation by 27
x = 4 / 3
Ava's share = 15x = 15 * 4/3 = 20
Charlotte's share = 12x = 12 * 4/3 = 16
Answer:
3
Step-by-step explanation:
The measure of the slope is 
at x = a
Differentiate using the power rule
(a
) = na
Given
y = x³ - 1, then
= 3x²
The slope at (1, 0) is
= 3(1)² = 3
Answer:
<em>x = 1</em>
<em>y = 1</em>
Step-by-step explanation:
<u>System of Equations</u>
We are given the system of equations:
2x + y = 3
x = 2y - 1
Substituting x in the first equation:
2(2y - 1) + y = 3
Operating:
4y - 2 + y = 3
5y = 3 + 2
y = 5/5 = 1
y = 1
Since:
x = 2y - 1
Then:
x = 2(1) - 1
x = 1
Solution:
x = 1
y = 1
Answer:
35
Step-by-step explanation:
70 takeaway 35 is 35 which is what is left over.
Answer:
A. v= $3,995.72 - $1,838.03
Step-by-step explanation:
Given:
fixed expenses: $1,838.03
total expenses: $3,995.72
We need to find the amount of Variable expense (v).
Now We know that;
Variable expense (v) can be calculated by Subtracting Fixed expense form Total expense.
framing in equation form we get;
Variable expense (v) = total expenses - fixed expenses.
Variable expense (v) = $3,995.72 - $1,838.03 = $2,157.69
Hence The equation represents Jessie's variable expense (v) = $3,995.72 - $1,838.03
