Answer: 10
you have to find a common denominator between two and five which is 10. therefore making the number 2 into the fraction 20/10 and finding the common denominator of 1/5 makes it now 2/10. now divide 20 by 2 which gets you 10. and dividing 10 by 10 gets you. therefore making the new fraction 10/1 which is equal to 10. :)
my teacher would like you to solve this using fraction ex:(345/x=727/2355) (just a heads up!!) please help :)
if tñ=2ñ+3, find S10
Answer:
[tex]S_{10}=280[/tex]
Step-by-step explanation:
Given that,
[tex]t_n=2n+3[/tex] ...(1)
We need to find the value of [tex]S_{10}[/tex].
Put n = 1 to find the first term.
[tex]t_1=2(1)+3=5[/tex]
Put n = 2 to find the second term.
[tex]t_2=2(2)+3=7[/tex]
Put n = 3 to find the third term.
[tex]t_3=2(3)+3=9[/tex]
Put n = 10 to find the tenth term.
[tex]t_{10}=2(10)+3=23[/tex]
It means we need to find the sum of 5,7,9,.....,23.
The formula for the sum of n terms is given by :
[tex]S_=\dfrac{n}{2}(a+a_n)[/tex]
We have, n = 10, a = 5 and [tex]a_n=23[/tex]
So,
[tex]S=\dfrac{10}{2}(5+23)\\\\S_{10}=10\times 28\\\\=280[/tex]
So, the value of [tex]S_{10}[/tex] is equal to 280.
Subtract 2w + 4 from 3w + 6 please help!!
Answer:
w+10
Step-by-step explanation:
3w+6-2w+4=w+10
Answer:
Step-by-step explanation:
x subtracted from y means y-x
2w+4 subtracted from 3w+6= (3w+6)-(2w+4)
don't forgett to diestribute invisible -1
-(2w+4)=-1(2w+4)=-2w-4
so
3w+6-2w-4=
3w-2w+6-4=
1w+2=

4x+8≥15-5x
adding 5x on each term
4x+5x+8≥15-5x+5x
9x+8≥15
subtract each term by 8
9x+8-8≥15-8
9x≥7

Given f(x) = x^3 + kx + 2, and x + 1 is a factor of f(x), then what is the value of
k?
Answer:
k = 1
Step-by-step explanation:
Given that,
[tex]f(x) = x^3 +kx + 2[/tex]
If (x+1) is a factor of (x), we need to find the value of k.
Using remainder theorem to find it.
Put (x+1) = 0
x = -1
Put x = -1 in equation below.
[tex]x^3 + kx + 2=0\\\\(-1)^3+k(-1)+2=0\\\\-1-k+2=0\\\\1-k=0\\\\k=1[/tex]
So, the value of k is 1.
what is the equation of the line passing through the point (2,-1) with a slope of -3
Note: this answer assumes that the equation of the line must be in slope-intercept form.
Answer:
[tex]y= -3x + 5[/tex]
Explanation:
When you need to write an equation and know its slope and a point it intersects, you can use the point slope formula [tex]y-y_1 = m (x-x_1)[/tex] first. In order to write an equation using this formula, the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] must be substituted in for real values.
The [tex]m[/tex] represents the slope, so write the slope of this equation, -3, in its place. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects. We know that the line must intersect the point (2, -1). Write 2 in the place of
[tex]y-(-1) = -3(x-(2))[/tex]
[tex]y+1 = -3(x-2)[/tex]
Now, to put it in slope-intercept or [tex]y = mx + b[/tex] form, just expand the right side and isolate [tex]y[/tex]:
[tex]y+1 = -3(x-2)\\y + 1 = -3x + 6 \\y = -3x + 5[/tex]
Therefore, [tex]y= -3x + 5[/tex] is the answer.

2 1/5 - 5/6 =
Answer:
2 1/5 - 5/6 = 41/30
Step-by-step explanation:
Turn the denominator to be the same because if the denominator is not the same so you can't subtract neither can you add.
Next find the least common multiple of both denominator (5, and 6) and ask yourself what time the denominator would give you the least common multiply you got.
1/5 x 6/6 = 6/30 and 5/6 x 5/5 = 25/30
Your expression now would be 2 6/30 - 25/30
You can't subtract 6 from 25 so you have to turn the proper fraction into a improper fraction
2 6/30 = 2 x 30 + 6 = 66/30. 25/30 = 0 x 0 + 25 = 25/30.
Your new expression would be:
66/30 - 25/30
Now you can subtract 66 - 25 and you get 41
Therefore the correct answer is 41/30 you can not simplify the answer because the numerator is a odd number and the denominator is a even number.

write the equation of a line
Answer:
y = 2x - 17
Step-by-step explanation:
y = mx + b
m = 2
y = 2x + b
Plug in (5, -7) for x & y.
-7 = 2(5) + b
-7 = 10 + b
Subtract 10 from both sides.
-17 = b
y = 2x - 17
Check work.
-7 = 2(5) - 17
-7 = 10 - 17
- 7 = -7

If 176 dollars = 100 pounds and 1 pound = NRs. 119,
how much Nepali rupees can be exchanged with 132 dollar? find it
Answer:
NRs. 8925
Step-by-step explanation:
176 dollars = 100 pounds
132 dollars = ??? pounds
Using cross-multiplication, we get:
176 dollars x ??? pounds = 100 pounds x 132 dollars
??? pounds = (100 pounds x 132 dollars)/ 176 dollars
??? pounds = 75 pounds
Now, 1 pound = NRs. 119
So 75 pounds = NRs. ???
Using cross-multiplication again, we get:
1 pound x NRs. ??? = NRs. 119 x 75 pounds
NRs. ??? = (NRs. 119 x 75 pounds)/1 pound
NRs. ??? = NRs. 8925
So the answer is 8925 Nepali rupees
The Nepali rupees can be exchanged with 132 dollar should be considered as the NRs. 8925
Calculation of the amount:Since
176 dollars = 100 pounds
And, for 132 dollars = ??? pounds
So here we applied cross multiplication
176 dollars x ??? pounds = 100 pounds x 132 dollars
??? pounds = (100 pounds x 132 dollars)/ 176 dollars
??? pounds = 75 pounds
Also, 1 pound = NRs. 119
Now
1 pound x NRs. ??? = NRs. 119 x 75 pounds
NRs. ??? = (NRs. 119 x 75 pounds)/1 pound
NRs. ??? = NRs. 8925
