Answer:
(1/7, 1)
Step-by-step explanation:
By "answer," you probably meant "solution." What is the "solution of the system of linear equations
- 5y = - 5
+ 7x +6y=7
The first eqation can be solved for y: y = 1. Substitute 1 for y in the secon equation. Then 7x + 6(1) = 7, or 7x = 1, or x = 1/7.
The solution to this system is (1/7, 1)
Answer:
Yes
Step-by-step explanation:
If you do 7x3 it equals 21.
A is correct. ...................................................
Answer:
$13.75
Step-by-step explanation:
the bill before the tip is x.
0.20x = 2.75
now divide both sides by .20
x= 2.75/0.20
x=13.75
To find the volume,we would first need to find the height of square pyramid, by it's base edge and slant height using Pythagoras theorem:
We can then use the pyramid formula to find the volume:
In this case,the volume will be:
10×_/69×1/3
=27.68874...
≈27.7 units^3
Hope it helps!
