Step-by-step explanation:
IF you meant it to convert into digits.
The difference of two numbers is 4. Their sum is 18. Find the numbers.
Answer:
11 and 7
Step-by-step explanation:
Let these two numbers be x and y where x is greater than y.
We can write two equations from the given information:
x - y = 4
and
x + y = 18
If we add them together, the y's cancel out:
x - y = 4
x + y = 18
2x = 22
x = 11
y is 4 less than x, meaning it is 7.
The two numbers are 11 and 7

Step-by-step explanation:
Factor the equation
please help
Answer:
For A
[tex]{ \rm{6 {x}^{2}(x + 1) - 2x(x + 1) }}[/tex]
• The equation above has a common bracket "(x + 1)". So, let's first factorise out that bracket:
[tex] \dashrightarrow \: { \rm{(x + 1) \{6 {x}^{2} - 2x \} }}[/tex]
• now in the second bracket, the common factor is x and 2.
[tex] \dashrightarrow \: { \rm{(x + 1) \{2x(3x - 1) \}}}[/tex]
• Final answer;
[tex]{ \boxed{ \boxed{ \rm{ \dashrightarrow \: 2x(x + 1)(3x - 1) \: \: }}}}[/tex]
For B
[tex]{ \rm{3(x - 1)(x + 2) + ( {x}^{2} - x)(x + 2) }}[/tex]
• In the equation, the common bracket is (x + 2).
So let's first factorise it out:
[tex] \dashrightarrow \: { \rm{(x + 2) \{3(x - 1) + ( {x}^{2} - x) \}}} \\ \\ { \rm{(x + 2) \{3(x - 1) + x(x - 1) \}}}[/tex]
• In the second major bracket, the common bracket is (x - 1). so factorise it out:
[tex]{ \rm{(x + 2) (x - 1) \{3 + x \}}}[/tex]
• Final answer:
[tex]{ \boxed{ \boxed{ \rm{ \dashrightarrow \: (x + 2)(x + 3)(x - 1) \: \: }}}}[/tex]

Answer:
Swimming Pool: $5000Caribbean: $15000Step-by-step explanation:
Let p and c represent the costs (in thousands) of swimming pool and Caribbean weddings, respectively. We have ...
5p +2c = 55 . . . . . total cost of the weddings
p = c -10 . . . . . . . . the difference in their cost
Substituting for p in the first equation gives ...
5(c -10) +2c = 55
7c -50 = 55
7c = 105
c = 15
p = 15 -10 = 5
The Swimming Pool weddings cost $5000; the Caribbean weddings cost $15,000.
If the meeting started at 12:15pm and it took 55 minutes what time did they finish?
Answer:
1:10 PM.
Step-by-step explanation:
If the meeting started at 12:15, it took 45 minutes to get to 1PM, however it lasted 10 minutes longer than that (55 minutes total). If 10 minutes of the meeting remains at 1PM, the meeting ended at 1:10PM. Therefore, 55 minutes after 12PM is 1:10PM.
For the polynomial shown below, find f(2).
f(x) = 2x^4+ x^3 - 4x - 3
Answer:
29
Step-by-step explanation:
Insert 2 in all the x's so, 2(2)^4+(2)^3-4(2)-3
so 32+8-8-3=29
Answer:
f(2)= 29
Step-by-step explanation:
f(x) = 2x^4 + x^3 - 4x -3
all you need to do is to place "2" anywhere you see x in f(x)
2(2)^4 + (2)^3 + 4(3) - 3
32+ 8 - 8 - 3
=29

Complete the table to find the rule for the reflection, the coordinates of triangle A′B′C′, and the coordinates of the reflected image, triangle A″B″C″.
When we reflect a point across an axis, the distance between the point and the axis stays the same, but is flipped to the opposite side.
We know that the coordinates of point A are (4,1), the coordinates of point B are (6,3), and the coordinates of point C are (2,4).
In this case, Triangle ABC is a reflection of point A'B'C' across the y-axis.
= reflection across the y-axis

Oliver drove the first 90 miles of his journey in 1.5 hours and the remaining 120 miles in 3 hours. What was the total average speed. (answer in mph)
Answer:
46 2/3
Step-by-step explanation:
Divide 90 by 1.5 because:
Average Distance= distance/time
then 120 by 3 for same reason
then u find each
then add 90 with 120 to get 210 then divide by 4.5 to get 46 2/3
Answer:
46.6666667
Step-by-step explanation:
we need to know the TOTAL average speed. To do that, we need to know how to get the speed, which is distance/time. Now we have to substitute. The equation we get is: s= (90+120)/(1.5+3). After solving, you should get s= (210miles)/(4.5hrs). Now all we have to do is divide, which equals 46.6666667.
Hope this helps! (:

Answer:
the first six square roots are 1, 3, 10, 5, 8 and 14.
Step-by-step explanation:
You will find yourself using square roots often enough to make it worth the effort to memorize the basic ones.
In the same order as presented here, the first six square roots are 1, 3, 10, 5, 8 and 14. That is, √1 = 1; √9 = 3; √100 = 10; and so on.
Christian has been offered a new job that pays $24,000 a year plus 3% of sales. For what total sales would this new job pay more than his current job which pays $60,000?
Answer:
$1,200,000
Step-by-step explanation:
Let x = sales
Since he gets 3% of a sale, we multiply x by 0.03
24,000 + 0.03x = 60,000
Subtract 24,000 from both sides
24,000 + 0.03x = 60,000
- 24,000 - 24,000
0.03x = 36,0000
Divide both sides by 0.03
0.03x/0.03 = 36,0000/0.03
x = 1,200,000

Anna pays $5.50 each day to park in a parking deck. How much will she pay for 5 days of parking?
Answer:
27.5 :))
Step-by-step explanation:
so this is the way i did it i breaked it down right so the equation is 5.50 x 5
take away the decimal and now its 550 and i did repeative addition of 5 until i got 2's of 1,100 i added them up then added the 2,200 + 550 without the decimal and i got 2750 instead of adding ',' i took the number 5.50 and saw there were two spaces under the numbers before it got to the decimal and it was two spaces so you do two hops like you do on a line in math so it basically turns to 27.50 :)) but you always take away the 0 if theres no number behind it so it turns to 27.5 :) but if the questions dont have the answer 27.5 then just add the 27.50! its the same number anyways :D ( i hope you understand it!)
Answer:
$27.5
Step-by-step explanation:
All you have to do is 5.50 multiplied by the number of days she is staying their, which is 5. Once you put that in, you get your answer which is 27.5!

Can you find the point-slope equation of the line that is parallel to y = -2x - 3 that passes through (0, 5)?
Answer:
y= -2x + 5
Step-by-step explanation:
Parallel equations share the same slope so, you need to take the x coordinate and multiply it by the slope which is -2, and you should get 0. To get from 0 to 5 we need to add 5, so 5 is your y-intercept.

A cricket pitch measures 1 chain by 10 feet. What is the area of a cricket pitch in square feet?
Answer:
660 square feet
Step-by-step explanation:
1 chain = 66 feet
Length ( l ) = 66 feet
Breadth ( b ) = 10 feet
To find :
The area of a cricket pitch in square feet = ?
The area of a cricket pitch in square feet will be in the shape of rectangle.
Formula : -
Area of a rectangle = lb
Area of a rectangle
= 66 x 10
= 660 square feet
Therefore,
660 square feet is the area of a cricket pitch.

x+4=3x+9 how to solve this?
Answer:
x = - [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
x + 4 = 3x + 9 ( subtract x from both sides )
4 = 2x + 9 ( subtract 9 from both sides )
- 5 = 2x ( divide both sides by 2 )
- [tex]\frac{5}{2}[/tex] = x
