7xy − 3xz + yz + 3xy − 5xz + 4yz?
7xy - 3xz + yz + 3xy - 5xz + 4yz equals 10xy - 8xz + 5yz.
−42x+3 + 5 ?
-42x + 3 + 5 equals -42x + 8.
`-4\left(2x+3\right)\ +\ 5\ ?`
-4(2x + 3) + 5 equals -8x - 12 + 5, which simplifies to -8x - 7.
1 39x+15
1/3(9x + 15) can be simplified to 3x + 5.
10−x−3
10 - x - 3 simplifies to 7 - x.
`10-\left(x-3\right)`
10 - (x - 3) can be simplified to 10 - x + 3, which further simplifies to 13 - x.
Evaluate the expression `\frac{9mn}{-2p}` when `m\ =\ \frac{1}{3},` `n\ =-2,`and `p=5.` Type your fractional answer below.
To evaluate the expression, substitute the given values into the expression:
\frac{9mn}{-2p} = \frac{9 \left( \frac{1}{3} \right) (-2)}{-2(5)}
Now perform the calculations:
\frac{9 \left( \frac{1}{3} \right) (-2)}{-2(5)} = \frac{9 \left( -\frac{2}{3} \right)}{-10} = \frac{-18}{-10}
The expression simplifies to \frac{9}{5}.
