The volume formula of a square pyramid is
V = 1/3 Bh (B is base).
Base area = 13 • 13
Base area = 169
Height = 11 m
Plug that in for:
V = 1/3 (169)(11)
V ≈ 619.66 or rounded is 619.67 cubic meters
Answer:
x = - 27/5
Step-by-step explanation:
Commutative Property
2x - 12x + 36 = 90
Combine like terms
-10x + 36 = 90
subtract 36 from both sides
-10x = 90 - 36
subtract numbers
10x = 54
Divide both sides by 10
x = - 27 / 5
Answer:
Hi there!
Your answer is;
Simplified equation is: 3m-2
M= 2/3
Step-by-step explanation:
First, distribute the negative to the parentheses
5m-2m-2
Next, combine like terms
3m -2
This is your simplified equation!
To solve for m;
3m-2
+2
3m= 2
/3
m= 2/3
Hope this helps
Answer:
0=0
Step-by-step explanation:
Simplifying
-5(x + -7) = 35 + -5x
Reorder the terms:
-5(-7 + x) = 35 + -5x
(-7 * -5 + x * -5) = 35 + -5x
(35 + -5x) = 35 + -5x
Add '-35' to each side of the equation.
35 + -35 + -5x = 35 + -35 + -5x
Combine like terms: 35 + -35 = 0
0 + -5x = 35 + -35 + -5x
-5x = 35 + -35 + -5x
Combine like terms: 35 + -35 = 0
-5x = 0 + -5x
-5x = -5x
Add '5x' to each side of the equation.
-5x + 5x = -5x + 5x
Combine like terms: -5x + 5x = 0
0 = -5x + 5x
Combine like terms: -5x + 5x = 0
0 = 0
Solving
0 = 0
Couldn't find a variable to solve for.
This equation is an identity, all real numbers are solutions.
-3x-y = -17
-x+y=-1
Using addition
-4x +0y = -16
-4x=-16
x=4
Then plug the value of x into one of the original equations
-x+y=-7
-(4)+y=-7
y=-7+4
y=-3
The solution is x=4 and y=-3
Thus (4,-3)
