-2 and 1/3 times 1 and 1/2=

torisob [31]

Answer:

$-2\frac{1}{3}\times 1\frac{1}{2}=-3.5$

Step-by-step explanation:

We are asked to find the product of $-2\frac{1}{3}$ and $1\frac{1}{2}$ .

Upon writing our expression as a product we will get,

$-2\frac{1}{3}\times 1\frac{1}{2}$

Let us convert our given mixed fractions to improper fractions.

$\frac{-7}{3}\times \frac{3}{2}$

Upon cancelling out 3 from our given expression we will get,

$\frac{-7}{2}$

Upon dividing -7 by 2 we will get,

$\frac{-7}{2}=-3.5$

Therefore, our expression simplifies to -3.5.

I need help finding the missing angle with work plz <br> ANSWER ASAP!!!!!!

Gemiola [76]

Answer:

The unknown angle is 80

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

Let the unknown angle be x

20+80+x = 180

Add like terms

100+x = 180

Subtract 100 from each side

100-100+x=180-100

x = 80
