Answer:
volume for cube = length cubed I.e. 6x6×6 = 216
Answer:
$8
Step-by-step explanation:
Here is the correct question: Mike bought 20 stamps for 0.40 each and 15 Century 0.32 each how much money did Mike spend on stamp.
Given: cost of each stamp is 0.40
Total stamp bought is 20.
Using unitary method
Cost of 1 stamp is 0.40.
∴ cost of 20 stamp is =
Cost of 20 stamp is $8
∴ Total money spent by Mike on buying 20 stamp is $8.
The final answer is (2,1).
Step 1: Solve for either x or y in one of the two equations.
x + 3y = 5
- 3y - 3y
----------------------
x = -3y + 5
Step 2: Substitute the expression you got for x into the opposite equation.
-3y + 5 - 3y = -1
-6y + 5 = -1
- 5 - 5
--------------------
-6y = -6
------ -----
-6 6
y = 1
Step 3: Plug in the solution you got for y into either of the 2 equations.
x + 3(1) = 5
x + 3 = 5
- 3 - 3
---------------
x = 2
Answer:
y = 4x - 3
Step-by-step explanation:
When we re-write the given equation into its slope-intercept form, it will like this:
y = (-1/4)x - 6
This line has a slope equal to -1/4 so the slope of the required line has a slope of +4 (perpendicular to the given line). Use this new slope and the given point P0(-1, -7) into this equation:
y - y0 = m(x - x0) ---> y + 7 = 4(x + 1)
Rearranging the terms into its slope-intercept form, we get
y = 4x - 3
