Answer:
I believe 7 is the GTF (greatest common factor)
Answer:
Step-by-step explanation:
A system of linear equations is one which may be written in the form
a11x1 + a12x2 + · · · + a1nxn = b1 (1)
a21x1 + a22x2 + · · · + a2nxn = b2 (2)
.
am1x1 + am2x2 + · · · + amnxn = bm (m)
Here, all of the coefficients aij and all of the right hand sides bi are assumed to be known constants. All of the
xi
’s are assumed to be unknowns, that we are to solve for. Note that every left hand side is a sum of terms of
the form constant × x
Solving Linear Systems of Equations
We now introduce, by way of several examples, the systematic procedure for solving systems of linear
equations.
Here is a system of three equations in three unknowns.
x1+ x2 + x3 = 4 (1)
x1+ 2x2 + 3x3 = 9 (2)
2x1+ 3x2 + x3 = 7 (3)
We can reduce the system down to two equations in two unknowns by using the first equation to solve for x1
in terms of x2 and x3
x1 = 4 − x2 − x3 (1’)
1
and substituting this solution into the remaining two equations
(2) (4 − x2 − x3) + 2x2+3x3 = 9 =⇒ x2+2x3 = 5
(3) 2(4 − x2 − x3) + 3x2+ x3 = 7 =⇒ x2− x3 = −1
Answer:
H. $360.71
Step-by-step explanation:
The 1 in $435.15 is in the tenths place. It has a value of 1/10. One tenth that value is 1/100. To have that value, a 1 would need to be in the hundredths place: 0.01.
Of the offered choices, the only one with a 1 in the hundredths place is ...
H. $360.71
Answer: B) 5 days
Explanation: 2 weeks is equal to 14 days. If you do 14 - 9 you get 5, which is equal to the amount of days after the due date.
Answer:
I believe the answer would be 55 degrees.
Step-by-step explanation:
Add together all the given angles then subtract that total from 360.
