Answer:
1/10
Step-by-step explanation:
First, find the probability of choosing the red pen:
There are 6 total pens and 3 are red, so the probability will be 3/6
This can be simplified to 1/2
Then, find the probability of choosing a blue pen after not replacing the red one:
There are 5 total pens now, since we did not replace the red one.
There is only 1 blue pen, so the probability is 1/5
Then, multiply these 2 probabilities together:
1/2(1/5)
= 1/10
So, the probability is 1/10
A puppy is on sale at a pet store for $324,marked down 10% from an original selling price of 360.
A. if the markup from coast to sale price was $54,what was the cost? Round to the nearest dollar.
B. How would you solve the problem if you were given the sale price? please help me if you can
Answer:
$ 360
Step-by-step explanation:
Puppy is on sale for = $ 324
It is marked down by 10% from original selling price of $ 360
Markup from the original buying cost = $ 54
Original Cost was = 360 - 54 = $ 306
$ 360 was the original price which was marked down by 10% i.e. $ 36 to the sale price of $ 324
Hector has caught 13 fish whose total weight on the scale is 43 pounds
5 ounces. He tells his friend that each fish likely weighs more than 3
pounds. The inequality below represents Hector's statement.
w>3 where w=weight of one fish
How reasonable is Hector's estimate?
Answer:
Hector's estimate is reasonable.
Step-by-step explanation:
His estimate is reasonable because:
43.5 ÷ 13 = 3.3461538461538461538461538461538This means that the weight of one fish is greater than three, therefore Hector's estimate is reasonable and correct.Joe pays $26.78 for 6.5 gallons of gas.

Evaluate r(x)=−x−7 when x=−2,0, and 5.
Answer:
-5, -7, and -12
Step-by-step explanation:
A function is defined as a relation between a set of inputs having one output each.
The values of the function r(x) at x = -2, 0 and 5 are -5, -7, and -12.
What is a function?A function is defined as a relation between a set of inputs having one output each.
The inputs are called the domain of the function.
The outputs are called the range of the function.
We have,
A function r(x)
r(x) = x - 7
The value of r(x) at x = -2:
r(-2) = - ( -2) - 7
r(-2) = 2 - 7 = -5
The value of r(x) at x = 0:
r(0) = -0 - 7 = -7
The value of r(x) at x = -2:
r(5) = -5 - 7 = -12
We see that,
Domain = -2, 0, and 5.
Range = -5, -7, and -12.
Thus,
The values of the function r(x) at x = -2, 0 and 5 are -5, -7, and -12.

Answer:
166°
Step-by-step explanation:
Since ∠A = ∠B,
the equation below helps to find the value of x and angle A:
7x + 40° = 3x + 112°7x - 3x = 112° - 40°4x = 72°x = 72°/4x = 18°∠A = 7*18° + 40° = 166°7x+40-180=3x+112-180
7x-3x=112-40
4x=72
x=18
A=7*18+40=126
B=21+112=133

Solve this
Answer:
-2
Step-by-step explanation:
6k=-24+12
or,6k=-12
or,k=-12/6
or,k=-2
Answer:
The value of k is -2.
Step-by-step explanation:
First, you have to add 12 to both side :
[tex]6k - 12 = - 24[/tex]
[tex]6k - 12 + 12 = - 24 + 12[/tex]
[tex]6k = - 12[/tex]
Next, you have to divide by 6 :

Write and solve an equation to find the number n. Six times the sum of a number and 15 is -42.
Answer:
8
Step-by-step explanation:
6*(n + 15) = -42
Divide both sides by 6
6*(n - 15)/6 = -42/6
n - 15 = -7
n = -7 + 15
n = 8
The equation is solved and the number is n = -22
Given data ,
The sum of a number and 15 can be written as (n + 15)
Six times the sum of a number and 15 can be expressed as 6(n + 15).
According to the given information, this expression is equal to -42. So, we can write the equation:
6(n + 15) = -42
To solve for n, we need to simplify and isolate the variable.
Distribute 6 to the terms inside the parentheses:
6n + 6(15) = -42
Simplify:
6n + 90 = -42
Next, we want to isolate the variable term. Subtract 90 from both sides of the equation:
6n + 90 - 90 = -42 - 90
Simplify:
6n = -132
Finally, divide both sides of the equation by 6 to solve for n:
n = -132 / 6
Simplify:
n = -22
Hence , the number n is -22

y=-7x-2 through (-4,6)
what is the equation in slope-intercept form?
Answer:
the equation that passes through this is y= -7x-22
Step-by-step explanation:
You want to find the equation for a line that passes through the point (-4,6) and has a slope of -7.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was -7. So you can right away fill in the equation for a line somewhat to read:
y=-7x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(-4,6). When x of the line is -4, y of the line must be 6.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: b is what we want, the -7 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the point (-4,6).
So, why not plug in for x the number -4 and for y the number 6? This will allow us to solve for b for the particular line that passes through the point you gave!.
(-4,6). y=mx+b or 6=-7 × -4+b, or solving for b: b=6-(-7)(-4). b=-22.
15x+6=10x+21 what’s x
Answer:

Step-by-step explanation:
[tex]15x+6=10x+21[/tex]
Subtract 6 from both sides:
[tex]15x+6-6=10x+21-6[/tex]
[tex]15x=10x+15[/tex]
Subtract 10x from both sides:
[tex]15x-10x=10x+15-10x[/tex]
[tex]5x=15[/tex]
Divide both sides by 5:
[tex]\frac{5x}{5}=\frac{15}{5}[/tex]

Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 3}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{15x + 6 = 10x + 21}[/tex]
Move 10x to left hand side and change it's sign
Similarly, move 6 to right hand side and change it's sign
[tex] \dashrightarrow{ \sf{15x - 10x = 21 - 6}}[/tex]
Collect like terms
[tex] \dashrightarrow{ \sf{5x = 21 - 6}}[/tex]
Subtract 6 from 21
[tex] \dashrightarrow{ \sf{5x = 15}}[/tex]
Divide both sides by 5
[tex] \dashrightarrow{ \sf{ \frac{5x}{5} = \frac{15}{5}}} [/tex]
Calculate

The least to greatest order is √9/4, 5/3, √5, and 2.5 after simplification the numbers.
What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
As we know,
The integer can be defined as the whole number it can be a negative whole number or a positive whole number for example 2, 4, 1, -8, 0, etc.
It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words, the irrational number cannot be expressed in the form of p/q form.
A rational number is a sort of real number that has the form p/q and does not equal zero.
Thus, the least to greatest order is √9/4, 5/3, √5, and 2.5 after simplification the numbers.

Given the function f(x) = –5|x + 1| + 3, for what values of x is f(x) = –12?
Answer:
x = 2, -4
Step-by-step explanation:
To find the answer to this question, we will have to find the values of x where:
-5|x + 1| + 3 = -12
We can solve this equation for x to find the values of x that satisfy this equation.
-5|x + 1| + 3 = -12
Subtract 3 from both sides.
-5|x + 1| = -15
Divide both sides by -5.
|x + 1| = 3
Now here, the equation will split off into two different equations. These two are:
x + 1 = 3
x + 1 = -3
Lets solve the first one first.
x + 1 = 3
Subtract 1 from both sides.
x = 2
Now we solve the second one.
x + 1 = -3
Subtract 1 from both sides.
x = -4
So now we have the answers x = 2 and x = -4.
So the values of x are x = 2, -4
