if 5k - 14= 26, then what is k?
Answer:
k = 8
Step-by-step explanation:
5k - 14 = 26
5k - 14 + 14 = 26 + 14
5k = 40
5k ÷ 5 = 40 ÷ 5
k = 8
someone help me with this please
Answer:
Step-by-step explanation:
Call the movie length m
3/4 m = 1 1/2 hours
3/4 m = 3/2 hours
This is easier to do by decimals
3/4 = 0.75
3/2 = 1.5
0.75 m = 1.5 Divide by 0.75
0.75/0.75 m = 1.5/0.75
m = 2
If it must be done using fractions then this is how it works.
3/4 m = 3/2
[tex]\frac{3*m}{4}=\frac{3}{2}\\m=\frac{\frac{3}{2} }{\frac{3}{4} }[/tex]
[tex]m= \frac{3}{2}*\frac{4}{3}\\\text{The threes cancel out. So does 2 into 4}[/tex]
You get 2 just as you did before.
Based on the figure below, what is the value of x? (5 points) A right angle is shown divided in two parts. The measure of the angle of one part is 30 degrees and the measure of the other part is 5x plus 15 degrees.
Answer:
Hello! answer: 9
Step-by-step explanation:
Assuming this is a complementary angle (meaning it will add up to 90 degrees)
5 × 9 = 45 45 + 15 = 60 60 + 30 = 90 therefore x = 9 Hope that helps!
a coffee retailer has two grades of decaffeinated coffee beans, one wholesales at $4.00 a pound and the other for 6.50 a pound. she wishes to blend the beans to form a 150 pound mixture that sells wholesale for 4.75 a pound. how many pounds of each grade of bean should she use in the mixture?
Answer:
Step-by-step explanation:
To solve mixture problems like this the best way is to make a table. Here's the basic format of the table we will use, calling the first coffee C1 and the second coffee C2:
#lbs x $/lb = Total
C1
C2
Mix
This is the table we will fill in. First, we were given the cost per pound of each type of coffee, so we put that in first:
#lbs x $/lb = Total
C1 4
C2 6.50
Mix
Next, we are told that she wants to make a mix of these coffees so she has a total number of pounds as 150 and that she wants it to cost $4.75 per pound. That goes in next:
#lbs x $/lb = Total
C1 4
C2 6.50
Mix 150 * 4.75
That asterisk is the multiplication sign.
Here's where we are now responsible for filling out the rest of the chart. If she needs to mix these 2 coffees to get a mix that is `150 pounds, she can have x pounds of C1 which means that she has to have 150 - x of C2:
#lbs x $/lb = Total
C1 x * 4
C2 150 - x * 6.50
Mix 150 * 4.75
Now all we have left to do is what the table tells us to do, which is to multiply the first 2 columns and put that product under the Total column:
#lbs x $/lb = Total
C1 x * 4 = 4x
C2 150 - x * 6.50 = 975 - 6.50x
Mix 150 * 4.75 = 712.50
Since we have to add the 2 coffees together to get the pounds of mix in the first column, we also have to add the cost of those coffees together to get the total cost of the mix. The equation looks like this:
4x + 975 - 6.50x = 712.50 and combining like terms:
-2.5x = -262.5 so
x = 105
That means that there is 105 pounds of coffee 1 and 150 - 105 pounds of coffee 2.
C1 = 105 pounds, C2 = 45 pounds
The product of two consecutive even integers is 36 less than 18 times their sum. Find the two integers
Answers:
There are two possible outcomes
The integers are 0 and 2The integers are 34 and 36If your teacher wants only positive integers, then go for the second scenario.
=========================================================
Explanation:
x = smaller integer
x+2 = larger integer
We can see that x+2 follows directly after x, so they are consecutive. Also, there's a gap of 2 units between the values. This is due to the phrasing "consecutive even" instead of just "consecutive".
Their product is x(x+2) = x^2+2x
Their sum is x+(x+2) = 2x+2
The product is 36 less than 18 times their sum, which means,
product = 18*(sum) - 36
x^2+2x = 18(2x+2) - 36
x^2+2x = 36x+36-36
x^2+2x = 36x
x^2+2x-36x = 0
x^2-34x = 0
x(x-34) = 0
x = 0 or x-34 = 0
x = 0 or x = 34
-------------------------------------------
If x = 0, then x+2 = 0+2 = 2
The product is x*(x+2) = 0*2 = 0
The sum is x+(x+2) = 0+2 = 2
If we multiply the sum by 18, then we get 18*2 = 36. Subtracting off 36 leads to 36-36 = 0
Therefore the equation below
product = 18*(sum) - 36
has been satisfied
-----------------------------------------
If x = 34, then x+2 = 34+2 = 36
product = x*(x+2) = 34*36 = 1224
sum = x+(x+2) = 34+36 = 70
then we can see that...
product = 18*(sum) - 36
1224 = 18*(70) - 36
1224 = 1260 - 36
1224 = 1224
So that works as well.
----------------------------------------
There are two possible outcomes
Either the integers are 0 and 2
OR
the integers are 34 and 36

what is the explicit formula for the nth term of the geometric sequence? -2,-16,-128,-1024
Answer:
an = a1 * [tex]8^{n-1}[/tex]
Couldn't find a subscript function so
an= a subscript n
a1 - a subscript 1
Step-by-step explanation:
What is the explicit formula for this sequence?
-6, -2, 2, 6, 10,....
Answer:
4n-10
Step-by-step explanation:
First we will use n as any number.
the difference between each of the numbers is +4
This creates first part of the formula.
4n...
If you do 4n and replace n as one (For the first number of the sequence) then 4×1=4. You then have to find out how much you need to add or subtract to get -6 so the difference between 4 and -6 is -10.
This creates the second part of our formula.
4n - 10
You can check this by doing the same thing for the second number and replacing n with 2.
2×4=8
8 - 10= -2 which is the second number in the sequence which confirms this is correct.

Gió thổi trên mặt nước trong các đại dương chịu trách nhiệm cho dòng hải lưu. Tuy nhiên, dòng hải lưu trong đại dương không được hình thành bởi gió đơn thuần. Nước gần cực lạnh trong khi nước gần xích đạo ấm. Sự chênh lệch nhiệt độ giữa hai vùng nước này cũng chịu trách nhiệm cho sự hình thành dòng hải lưu. Địa hình đáy đại dương, mưa và thậm chí thủy triều cũng gây ra dòng chảy trong nước.

SOMEONE PLS HELP ME FIND X
Answer:
step one you look at the question until you find the ex cuz it says 125 degrees and 125 degrees 2x
Answer:
x = 50
Step-by-step explanation:
The sum of all entire angles in this, esentially a pentagon, add up to 540
To find x, use the following
540 = 125 + 125 + 90 + 2x + 2x
540 - 125 - 125 -90 = 4x
200 = 4x
200 / 4 = x
50 = x

solve for j
PLEASE SHOW WORK IF YOU CAN
Answer:
j = 15
Step-by-step explanation:
The angles shown form a straight line
Angles on a straight line must add up to 180 degrees
Hence, 2j + 32 + 6j - 2 + 30 = 180
( note that we just created an equation that we can use to solve for j )
We now solve for j using the equation we created.
2j + 32 + 6j - 2 + 30 = 180
step 1 combine like terms
2j + 6j = 8j
32 - 2 + 30 = 60
we now have 180 = 8j + 60
step 2 subtract 60 from each side
60 - 60 cancels out
180 - 60 = 120
we now have 120 = 8j
step 3 divide each side by 8
120 / 8 = 15
8j / 8 = j
we're left with j = 15

Find the value of x.
Answer:
100
Step-by-step explanation:
The two angles form a straight line which is 180 degrees
5+x +75 = 180
Combine like terms
x+80 = 180
Subtract 80 from each side
x +80-80=180-80
x = 100
Answer:
x=100°
Step-by-step explanation:
(5+x)°+75°=180°(being a straight line)
x=100°

The left side of the box represents quartile 1
The right side of the box is hovering over 85
The right side of the box represents quartile 3
The whisker at the end of the right side is hovering over 100
The whisker at the very end of the right represents the maximum
Hence, we can conclude that the answer is Q1 Q3 maximum
Would you rather be reborn into the past or future? Why?
Would you rather go into the past and meet your ancestors or go into the future and meet your great-great grandchildren? Why?
Would you rather have a rewind button or a pause button on your life? Why?
(I'm aware that this isn't a mathematical question, this is simply just for fun:)
Answer:
Future just cause I don't really have much interest about the past, moving forward as always. I'd like to see how things advance over time :")
I think a rewind is more useful in this case if I am able to correct my mistakes or have a moment back again, I'd like that.
