1/3<span> is </span>bigger <span>because the three in </span>1/3<span> is less than 1/4 &1/5. </span>
Lets check all the choices:
A. subtraction:
(3x+2)-(4y-11)=3x+2-4y+11=3x-4y+13
similarly, (4y-11)-(3x+2)=-3x+4y-13
both are polynomials (of 2 variables)
B. (3x+2)(4y-11)=12xy-33x+8y-22, which is a polynomial
C. (3x+2)+(4y-11)=3x+2+4y-11=3x+4y-9, which is a polynomial
D.
both
and
are rational expressions in 2 variables, not polynomials
Answer: D
You just told us that 't' is the tax, and 'c' is the cost of the item.
We know it's not the 'equals' sign (=), so the only thing left
that it could be is the 0.07 .
Answer:
d equals 2 if that's what u need
To add 1/2 and 1/4 you need a common denominator. The common denominator is 4. Multiply 1/2 × 2/2 and you get 2/4
Now you have 6 2/4 + 2 1/4
6+2=8 and 2/4+1/4=3/4
Your answer is 8 3/4 or 8.75
