Answer:
(0, 3 )
Step-by-step explanation:
Given the 2 equations
x + 3y = 9 → (1)
- 2x + 2y = 6 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the x- term
2x + 6y = 18 → (3)
Add (2) and (3) term by term to eliminate x, that is
0 + 8y = 24
8y = 24 ( divide both sides by 8 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
x + 3(3) = 9
x + 9 = 9 ( subtract 9 from both sides )
x = 0
solution is (0, 3 )
The college student spends 45 dollars on laundry.
To find this you have to divide 495, by 11. This is because the question states "the college student spends 10 times more on pizza than laundry", which means the cost of the laundry (l) is added to the cost of pizza (10p). Dividing 495 by 11, you get 45.
As I stated earlier, the cost of laundry is added to the cost of pizza. 45 * 10 is 450. 450 + 45 = 495. Thus making 45 the answer.
I hope this helps!
Answer:
Step-by-step explanation:
Let
x -----> the number of hours that the painter works
we know that
The inequality that represented this situation is equal to
solve for x
Subtract 60 both sides
Divide by 15 both sides
The maximum number of hours is 2
It would take approximately 4.5 seconds
Answer:
1st Option is correct that is we get circle after slicing a right circular cylinder in small pieces.
Step-by-step explanation:
Given: Jamal Sliced aright circular cylinder into congruent pieces.
To find: Shape of Two-Dimensional plane section obtained after slicing.
We get congruent pieces only when we slice the cylinder parallel to its base at equal heights.
By doing this we get small pieces of cylinders of equal height and equal radius.
Base and top remains same that is circular in shape.
Therefore, 1st Option is correct that is we get circle after slicing a right circular cylinder in small pieces.
