X=7, y=3
because it is an algebraic method you have to solve for an x or y in either equation, and then plug that into the other equation. it’s helpful for these problems to check your work and plug the numbers back into the equations and the end for future reference !
Answer:
D
Step-by-step explanation:
Given the 2 equations
4x + 8y = 21 → (1)
y = - 
x + 3 → (2)
Substitute y = - x + 3 into (1)
4x + 8(- x + 3 ) = 21 ← distribute parenthesis on left side
4x - 4x + 24 = 21 ( subtract 24 from both sides )
0 = - 3 ← not possible
This indicates the system has no solutions
Answer:
732π cm^3
Step-by-step explanation:
Volume of the biggest cone
(15^2 * π *20)/3 = 1500π cm^3
Volume of the smallest cone
20^3 : 16^3= 1500π : x
x = (1500π * 4096)/8000= 768π cm^3
Volume of the frustum = 1500π - 768π = 732π cm^3

Answer:
$25830
Step-by-step explanation:
If 100% of the car price is 24,600 , then you can imagine that extra 5% being added to this
100 + 5 = 105
So you need to find what 105% of the cost was.
To do this you can use the percentage formula:
Amount x 
Now, you can simply plug the values into this
24,600 x 
24600 x 1.05 = 25830
<h3>So the total cost including tax would be $25830!</h3><h3 /><h2>Hope this helps!</h2>
