We don't know the value of the number, so we call it x.The quotient of a number and negative five is:[tex]\frac{x}{-5} = -\frac{x}{5}[/tex]
One less than the quotient is:[tex]1 - (-\frac{x}{5}) = 1 + \frac{x}{5}[/tex]
--------------------------------
Supposing this is equals to 5.[tex]1 + \frac{x}{5} = 5[/tex]

An online store sells only two types of bandanas: cotton bandanas and silk bandanas. Cotton bandanas cost $7 each, and silk bandanas cost $11 each. Mrs. Tran spent a total of $93 on bandanas at this store. How many cotton bandanas did Mrs. Tran buy
Given :
An online store sells only two types of bandanas: cotton bandanas and silk bandanas. Cotton bandanas cost $7 each, and silk bandanas cost $11 each.
Mrs. Tran spent a total of $93 on bandanas at this store.
To Find :
How many cotton bandanas did Mrs. Tran buy.
Solution :
Let, number of cotton and silk bandanas buys are x and y respectively.
So, 7x + 11y = 93
x = (93 - 11y)/ 7
Putting y = 1 , x = 82/7 ( not possible since x can only be positive integer )
Putting y = 4 , x = 7
Therefore, Mrs . Tran will buy 7 cotton bandanas.
Hence, this is the required solution.
what is slope and y interceapt
Answer:
slope- 1
y-int- y=2x+-2
Step-by-step explanation:
In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form".

The diagram to the right of airport runaways intersection shows two parallel runways. A taxiway crosses both runways use the diagram to answer the question.
Answer:
m<4 is the measurement of 20°
and m<1 is the measurement of 33°
and in order to get 127° is to subtract 180° by 127° then that gives you 53° then you ether divide 53° by 180° or, you divide 53° in half, which gives you 33° for measurement 1™ and measurement 4™ gives you 20°
Step-by-step explanation:
The sum of angles m∠1 and m∠4 is 254°.
What is an angle?When two lines meet at a point, the geometrical figure that is formed is called an angle.
Here the taxiway crosses two parallel airplane runways.
Now, the m∠8 = m∠4 (these are corresponding angles)
Again, m∠4 = m∠1 (these are opposite angles)
Therefore, sum of angles m∠1 and m∠4
= (m∠1 + m∠4)
= (m∠8 + m∠8)
= 2 × m∠8
= 2 × 127°
= 254°

Find the probability that x <-3
Answer:
Step-by-step explanation: if you want to obtain the probability that x [tex]\leq[/tex]-3 , then you need to add the probability for the cases x=-3 and x=-5.
p=0.13+0.17= 0.3
answer=0.3
The probability that x ≤ -3 will be the sum of 0.13 + 0.17 = 0.30.
What is probability?The probability of an event occurring is defined by probability.
Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
As per the given probability distribution.
The probability distribution is the probability of different cases.
In cases the probability adds thus,
P(x ≤ - 3) = P (x = -3) + P(x = -5)
⇒ 0.13 + 0.17 = 3
Hence "The probability that x ≤ -3 will be the sum of 0.13 + 0.17 = 0.30".
