Three consecutive integers have a sum of 87. Find the integers.
Answer:
28, 29, 30Step-by-step explanation:
Let the integers be x- 1, x and x +1, then:
x - 1 + x + x + 1 = 873x = 87x = 29The integers are 28, 29, 30
Answer:
Let the numbers be (x-1), x and (x+1)
According to the above problem,
[tex](x - 1) + x + (x + 1) = 87 \\ 3x = 87 \\ \boxed{x = 29}[/tex]
Therefore, the numbers are 28, 29 and 30.

Answer:
3a
Step-by-step explanation:
Here we have to divide like terms that means 9 by 3, a^3 by a^2 and b by b. 9 by 3= 3, a^3 by a^2=a after subtracting power 3 and 2 we get 1 and b by b are both cut like dividing 2 by 2 is cut and we get 1 which is not necessary to write as there would be no difference in ans.

Bookers father sells computer and earns a 4.25 commission on every software package he sells. How much commission would he earn on software package that sold for 15,725 round to the nearest cent
Answer:
Commission= $668
Step-by-step explanation:
Giving the following information:
Commission rate= 4.25% = 0.0425
Sales= $15,725
To calculate the commission earned, we need to use the following formula:
Commission= commission rate*sales
Commission= 15,725*0.0425
Commission= 668.3125
Commission= $668

The point-slope form of the equation is
9514 1404 393
Answer:
the value of x1 is 6the value of y1 is -1the point-slope equation is: y +1 = 2(x -6)Step-by-step explanation:
Point-slope form is ...
y -y1 = m(x -x1) . . . . . . line with slope m through point (x1, y1)
The given point is (6, -1), so ...
x1 = 6
y1 = -1
The given slope is 2, so ...
m = 2
Substituting these into the point-slope form above gives ...
y -(-1) = 2(x -6)
y +1 = 2(x -6)
Answer:
y+1= 2(x-6)
Step-by-step explanation:
Hi! Before we begin answering the question, we need to recall the formula for Point-Slope Form which is y- yı= m(x-xi), in which m is the slope of the function. With this given information, we just need to plug in the point (6,-1) and the slope 2 into the given function.
This will look like:
y- (-1) = 2 (x-6)
Notice that two negatives will make a positive, so the left side of the equation is the same as y+1.
Therefore, our answer is y+1= 2(x-6) .
Algebra...George bought 2 identical couches and 3 identical chairs. A couch cost twice as much as a chair. He spent $270 more on th ecouches than on the chairs. How much did he spend altogether
Answer:
$1890
Step-by-step explanation:
x= couches
y=chair.
x=2y
2x=3y+270
2(2y) or 4y=3y+270
y=270
x=540
2(540)+3(270)=1890.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
George bought 2 identical couches and 3 identical chairs.
A couch costs twice as much as a chair.
Let the cost of one couch = 2x
Let the cost of one chair = x
Now,
He spent $270 more on the couches than on the chairs.
This means that,
2(2x) = 270 + 3x
4x = 270 + 3x
Subtract x on both sides.
x = 270
The total spending.
= 4x + 3x
= 4 x 270 + 3 x 270
= 1080 + 810
= $1890
Thus,
The total spending is $1890

If a video is getting 12,000 views every 4 hours, how long will it take to reach 30,000 views?
Step-by-step explanation:
12,000 views = 4 hours
=> 30,000 views = 4 * (30000/12000) = 10 hours.
Hence it will take 10 hours.
Answer:
10
Step-by-step explanation:
Since we know every 4 hours the vid recieves 12,000 views, we divide 12,000 by 4 to see how many views it recieves in 1 hour. We get 3,000. So 3,000 views every hour. Divide 30,000 by 3,000, to get 10 hours.

Factorize
The options are not given; So, I'll answer on a general term

Express -9 as -3 * 3

Then factorize 3 out of the expression as:
[tex]-3x - 9 = 3(-x - 3)[/tex]
Another way is to factor -3 out of the expression as:

please show working
Answer:
Step-by-step explanation:
1. u^2 = x^(p+q)
v^2 = x^(p-q)
Show that logx u + logx v = p
From statement 1
p + q = logx u^2 = 2 logx u (by the laws of logs)
Similarly:
p - q = logx v^2 = 2 logx v
So 2 logx U + 2 logx v = p+q + (p - q)
2 (logx u + logx v) = 2p
logx u + logx v = p.
Also 2(logx u - logx v) = p+q - (p - q) = 2q
and logx u - logx v = q.
2. ∛(8a^3b^3) / √(1/25 * a^4b^7)* (16√(a^4b^6))^-1/2
= 2ab / 1/5a^2b^7/2 * (16a^2b^3)^-1/2
= 2ab / 1/5a^2b^7/2 * 1 / 4ab^3/2
= 2ab / 4/5 a^3 b^5
= 5ab / 2 a^3 b^5
= 5/(2a^2b^4).

How many positive four-digit integers have the three digits the same and a different fourth digit (in some order)
Answer:
81 * 4 = 324.
Step-by-step explanation:
There are 81 * 4 = 324 such integers.
There are 9000 four-digit integers from 1000 to 9999. Let’s refer to the digit that occurs three times as the triplet and the digit that occurs once as the singleton.
In the first (most significant) position there are 9 possible values for the singleton, 1 through 9. In each case there are also 9 possible values for the triplet. For example if the singleton was a 1, the triplets could be anything but a 1: 1000, 1222, 1333, …, 1999. So there are 9 * 9 = 81 cases with the singleton in the first position.
A singleton in the second position can have 10 possible values, 0 through 9. If it’s a 0 there are 9 possible values for the triplet: 1011, 2022, 3033, …, 9099. If it’s anything else there are only 8 possible values for the triplet since the triplet cannot be 0: 2122, 3133, 4144, …, 9199. So there are 9 + (8 * 9) = 81 cases with the singleton in the second position.
The third and fourth positions work just like the second. So the grand total is 81 * 4 = 324.
If you plot the 9000 four-digit integers as a 100 x 90 grid of squares and color the integers with three same digits in red, an interesting pattern occurs:

L 5.2.3 Quiz: Two-Variable Systems: Substitution
Question 7 of 10
Use the substitution method to solve the system of equations. Choose the
correct ordered pair.
y = 10x-9
y = x + 18
Answer:
We get x=3 and y=21
The ordered pair will be: (3,21)
Step-by-step explanation:
We need to use the substitution method to solve the system of equations.
[tex]y = 10x-9\\y = x + 18[/tex]
For substitution method we substitute the value of x or y from one equation to other.
Let:
[tex]y = 10x-9--eq(1)\\y = x + 18--eq(2)[/tex]
Putting value of y from equation 2 into equation 1
[tex]y=10x-9\\Put\:y=x+18\\x+18=10x-9\\x-10x=-9-18\\-9x=-27\\x=\frac{-27}{-9}\\x=3[/tex]
So, we get value of x=3
Now, for finding value of y, We substitute the value of x
Find value of x from equation 2
[tex]y=x+18\\x=y-18[/tex]
Now, putting value of x in equation 1
[tex]y=10x-9\\Put\:x=y-18\\y=10(y-18)-9\\y=10y-180-9\\y-10y=-189\\-9y=-189\\y=\frac{-189}{-9}\\y=21[/tex]
So, we get value of y=21
So, We get x=3 and y=21
The ordered pair will be: (3,21)
-10 F is colder than -4 degrees?
Answer: yes, it is a smaller temperature, which means that is "colder"
Step-by-step explanation:
I guess that the question is:
Is -10°F colder than - 4°C?
Ok, when we have a temperature T in Celcius, the equation to transform this quantity to the Fahrenheit scale is:
T' = (T*9/5) + 32°
Replacing T by the temperature in celcius, we get:
T' = (-4°*9/5) + 32° = 24.8°F
This means that -4°C is equivalent to 24.8°F
And -10°F is a smaller value than 24.8°F (which mean that is colder)
This implies that -10°F is colder than -4°C
Then the statement is true.
