answer:

40°

step by step:

93°+47° (i think the circle at the bottom says 47)=140°

180° ( as the angles in a triangle must add up too 180°) - 140° = 40°

3=7-2(3z+2)<br> How to solve

attashe74 [19]

Answer: z = 0 | Equation is not solvable

Step-by-step explanation:

We have 3 = 7 - 2(3z + 2)

When we distribute the 2, we get: -6z - 4 + 7 = 3

Combine like terms: -6z + 3 = 3

Subtract the left hand side 3 from the right hand side 3: -6z = 0

We can not divide by zero thus the equation is not solvable.

A pet store has 10 cats, 9 dogs, and 8 turtles. If Mario randomly selects a pet to take home, determine his Theoretical Probabil

ololo11 [35]

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

STEP (1)

We have to know how many pets does the pet store have.

Look : 10 + 9 + 8 = 27

So the pet store completely have 27 pets.

_________________________________

STEP (2)

Mario randomly selects a pet :

$\frac{10}{27} \\$

Is the Probability of selecting a cat.

##############################

$\frac{9}{27} \\$

Is the Probability of selecting a dog.

_________________________________

STEP (3)

(( or )) in mathematics means plus (( + )) .

So the Probability of selecting a cat or a dog means :

$\frac{10}{27} + \frac{9}{27} = \frac{19}{27} \\$

_________________________________

STEP (4)

There's no STEP 4.

And we're done.

Thanks for watching buddy good luck.
