I don't know if it wants me to find the interest from the bond or the quote price of the bond.
If it is the bond it would be $1400 interest.
If it is the quote price of the bond, it would be $1,239 interest.
0.4x = 32
Solve for x
x = 32/0.4
x = 80
Answer:
a. =11+ 1
b. =4x+ (-7y) + (-5z) +6
c. (-3x) + (-8y) +(-4)+(-8/7z)
Step-by-step explanation:
a. 20 - 9 + 8 -7
=11+ 1 ( this is obtained by solving)
b. 4x - 7y - 5z + 6
=4x+ (-7y) + (-5z) +6
We multiply the negative sign with the positive sign to get a minus so the answer remains the same and the expression is written as an addition sum.
c. -3x - 8y - 4 - 8/7z
-[ 3x+8y+4+8/7z]
or
(-3x) + (-8y) +(-4) +(-8/7z)
The minus sign is taken as common leaving the expression with the plus only.
It can be written in the same manner as above, adding the negative terms so that the expression is written as a sum.
The expressions are a sum after the negative sign is marked with the terms. It shows that the negative terms are being added.
