12/-4 = pls help i don’t understand

Sveta_85 [38]

$\text {Hello! Let's Solve this equation!}$

$\text {Since there is a negative in the problem this tells us that the answer we get will be a negative.}$

$\text {Here are some tips on dividing/multiplying equations like this.}$

$\text {Multiplying/Dividing a Positive to a Positive will equal a Positive}\\\text {Multiplying/Dividing a Positive to a Negative will equal a Negative}\\\text {Multiply/Dividing a Negative to a Negative will equal a Positive}\\\text {Multiplying/Dividing a Negative to a Positive will equal a Negative}$

$\text {Now Divide!}$

$\text {12/-4=}$

$\fbox {-3}$

$\text {As you can see 4 is a negative number so our result came out as a negative number.}$

$\text {Want to see if your answer is correct? Sure! Do the opposite of Dividing and Multiply!}$

$\text {-3*-4=12}$

$\text {Best of Luck!}$

Authur earned $136 in three weeks. He goes back to school in one more week. He needs at least $189 to buy the new coat that he w

Nady [450]

Answer:

136+ m ≥ 189 is the required inequality : m: The earning in 4th week

Arthur needs to earn AT LEAST $53 in the fourth week to buy the coat which costs at least $189.

Step-by-step explanation:

The amount earned by Arthur in first 3 weeks = $136

The amount needed to buy a coat = AT LEAST $189

Let us assume the amount Arthur needs to earn more to buy coat = $m

⇒ $ 136 + Amount Earned in 4th week ≥ $189

⇒ 136+ m ≥ 189

The above equation is the NEEDED inequality of the given situation.

Now, solving for the value of m, we get:

136+ m ≥ 189

⇒ m ≥ 189 - 136 = 53

or, m ≥ $53

Hence, Arthur needs to earn AT LEAST $53 in the fourth week to buy the coat which costs at least 189.

If csc θ=8/7, which equation represents cotθ

TEA [102]

Sin θ = opposite leg/hypotenuse
csc θ = hypotenuse /opposite leg =8/7

cot θ = adjacent leg/opposite leg

hypotenuse =8
opposite leg =7
We need to find adjacent leg.

(Opposite leg)² +(adjacent leg)² = hypotenuse²
7² + (adjacent leg)² =8²
(adjacent leg)² = 64 - 49
(adjacent leg)² = 15

adjacent leg=+/-√15
WE need only positive root,
so adjacent leg =√15

cot θ = √15/7 or 0.5533
