Answer:
1,578
Step-by-step explanation:
I took the test
the length of the box is represented by (8m2)
does that mean 8m^2?
in English that would be 8 times m^2 or 8 * m * m.
if that is true, then the volume of the box would be equal to (8*m^2)^3 which is equal to 8^3 * m^6 which is then simplified further to 512 * m^6 which can also be written as 512m^6.
if we assume that m is 3, then the side of the box is equal to 8 * 9 which is equal to 72 and that is cubed to get 373248.
working that out algebraically, it would look like this:
(8*3^2)^3 equals 8^3 * (3^2)^3 which is equal to 8^3 * 3^6 which is equal to 512 * 729 which is equal to 373248

System of Linear Equations entered :
[1] 3x - y = 19
[2] 8x - 5y = 20
Graphic Representation of the Equations :
y + 3x = 19 -5y + 8x = 20
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 3x - 19
// Plug this in for variable y in equation [2]
[2] 8x - 5•(3x-19) = 20
[2] -7x = -75
// Solve equation [2] for the variable x
[2] 7x = 75
[2] x = 75/7
// By now we know this much :
x = 75/7
y = 3x-19
// Use the x value to solve for y
y = 3(75/7)-19 = 92/7
Solution :
{x,y} = {75/7,92/7}
The answer would be -7 because -7 is 5 less than -2 on a number line
Answer:
True
Step-by-step explanation:
A common denominator of the mixed numbers is 20. select True or false
Mr. Clements painted his barn for 3 3/5 hours in the morning.
He painted the barn for 5 3/4 hours in the afternoon.
Now we consider the denominator of both fractions 18/5 and 23/4
Least common denominator is 5 times 4 = 20
So its true that the common denominator of mixed numbers is 20
