8 + 6.2 + 4a - 9a
(8 + 6.2) + (4 - 9)a
14.2 - 5a is your answer.
Answer:
Well,[tex]8+4a+6.2-9a[/tex] has like terms. The simplified expression would just be these like terms combined.
First, let's combine [tex]8[/tex] and [tex]6.2[/tex]
[tex]8+6.2=14.2[/tex]
[tex]4a-9a+14.2[/tex]
Now, combine the other two monomials.
[tex]4a-9a=-5a[/tex]
[tex]-5a+14.2[/tex] would be your answer.
Remember: Some terms can't be combined. For example, [tex]4a[/tex] and [tex]8[/tex] cannot be added together, due to the [tex]a[/tex] in [tex]4a[/tex]. These are not like terms. But [tex]4a[/tex] and[tex]-9a[/tex] are, and can indeed be combined.
The diameter of the moon is about 3,476 kilometers the distance from earth to the moon is about 384,400 kilometers about how many moons could be lined up in a row between earth and the moon round the nearest whole number
384,400 /3476 = 110.587 so 111
because .587 is more than half way from 110 to 111
Remark
You have to make up your own formula here. You also should estimate the answser. That's always good practice. It makes you think about Math.
Estimate
If you take 384,000 and estimate it to be 300000 and do the same with the diameter to make it 3000
300,000 / 3000 = 100 about. You should get an answer of 100
Formula
Distance to the moon (D)= number of moons (n) * diameter of 1 moon (di).
Givens
D = 384000
n = ??
di = 3476
Solution
384000 = n * 3476 Divide by 3476
384000 /3476 = n / 3476
n = 110.5 moons which I think you should like round to 110.
You could fit 110 moons in the given distance
Determine the slope of the line that passes through the points (-5, -4) and (0, 10).
so the equation for slope is y2-y1/x2-x2
so this would be -4-10/-5-0 which equals -14/-5 which is the same thing as 14/5
so the answer is 14/5 or if its mixed then 2 4/5
Hope this helps!

A(x+b)-c=d
How can I find the area of this?
Find the area of each triangle and then add them together.
Bottom Triangle
A = [tex]\frac{1}{2}[/tex]b * h
= [tex]\frac{1}{2}[/tex](160)(120)
= 80(120)
= 9600 m²
Top Triangle
First we need to find the side length. We can calculate the length of the hypotenuse using Pythagorean Theorem for the bottom triangle.
a² + b² = c²
120² + 160² = c²
14400 + 25600 = c²
40000 = c²
200 = c
Now we can use Pythagorean Theorem on the top triangle to find the missing side length.
a² + b² = c²
100² + b² = 200²
10000 + b² = 40000
b² = 30000
b ≈ 173
A = [tex]\frac{1}{2}[/tex]b * h
= [tex]\frac{1}{2}[/tex](100)(173)
= 50(173)
= 8650 m²
Top Triangle + Bottom Triangle = Total Area
8650 + 9600
18250
Answer: Area = 18,250 m²
Larry is 10 and his sister is 7 years old. In how many years time will their total age be 25 years?
about 47% of the 15152 samples researchers found were bacteria. what number of dna samples were not bacteria
To find what number of DNA samples were not bacteria we have to find what was 47% of the 15,152 samples first.
We can do this by multiplying 0.47 x 15,152 = 7,121.44
Now 7,121.44 is 47% of the samples that DOES have bacteria. To find out how many do not we must subtract.
15,152 - 7,121.44 = 8,030.56
So the number of DNA samples that were not bacteria were 8,030.56.
GOOD LUCK! :)

how much does the medium smoothie cost?
2 jumbo + 1 medium = 4 med + 0.15
Multiply 2 jumbo smoothies by 2 which is >> 9.90+m =4 m+0.15
9.75=3m
Divide and it'll be 3.25
3.25=m
I Actually spent a hour trying to write an answer as it also challenged me, then i saw how simple it is i wish i could take back my time
Anyways, to find out the amout a medium smoothie cost we need to find the equation for it. With the given information we can find out that the cost of 4 medium smoothies is the same as 2 jumbos and one smoothie.So first lets find out the cost of 2 smoothies, 4.95 * 2 = 9.9.Now lets plot them into an equation.
4x+0.15=9.9+x
Simplyfy the equation by removing the x from the right side
4x-x=3x x-x=0
so now our new equation is
3x+0.15=9.9
Next lets remove the 0.15
0.15-0.15 = 0 9.9-0.15=9.75
so our new equation is now
3x=9.75
Then, we simplify the x by dividing the amount of x's it has
3x/3=x 9.75/3=3.25
So, after doing all that math, we found out that x=3.25
So each smoothie costs $3.25
so, the equation would be 4x+0.15=9.9+x
We can test it out by plotting in the situation
(3.25*4)+0.15=13.15 9.9+3.25=13.15
Don't forget to add the extra amount.
I am so glad i was able to find this out, and hope this helps you, as i had trouble with it myself, and thats coming from someone who's taking honors!

You work 20 hours a week at a store in our $8.50 per hour. At another job you earn $8.00 per hour and can work as many hours as you want. If you want to earn $370 for the week, how many hours will you need to work at the second job?
For the second job you work for $8.00 per hour and you want to make $370 for the week so its just simple division.
$370/$8.00 is 46.25 hours a day which means you will have to work close to 46-47 hours a day to make $370 in a week.

To find the inverse of f(x) = 5x + 4, swap x and y to get x = 5y + 4, solve for y to get y = (x - 4)/5, which is the inverse.
With the given function f(x) = 5x + 4, we first replace f(x) with y to get y = 5x + 4. We then swap x and y to get x = 5y + 4. To solve for y, we subtract 4 from both sides, giving us x - 4 = 5y. Then, we divide both sides by 5, yielding (x - 4)/5 = y. Therefore, y = (x - 4)/5, which is the inverse of the function f(x).
4+2p_< 3p -1 can somebody answer this for me
Answer: p ≥ 5
Step-by-step explanation:
Subtract 4 from both sides :
4+ 2p - 4 ≤ 3p-1 - 4
Simplify :
2p ≤ 3p -5
Subtract 3 p from both sides
2p - 3p ≤ 3p - 5 - 3p
Simplify:
- p ≤ - 5
Multiply both sides by -1 (reverse the inequality right) :
( - p ) * ( - 1 ) ≥ ( -5 ) * ( - 1 )
Simplify :
p ≥ 5
Hope that helps!
6x4=8xN
How can I solve this
6×4=24 right so than how many 8 can get you to 24, so you do 8,16,24 or 8×3 So it's 8×3=24 (Your welcome ^.^)
6x4=8xN is the same as 24=8N
Divide both sides by 8 and there's your answer
Find the equation of the line that is perpendicular to the line y=-1/3x-1 and passes through the point (1,5)
To find the equation of the line perpendicular to y = -1/3x - 1 and passing through the point (1,5), we use the negative reciprocal of the original slope (which is 3) and the point-slope form to finally arrive at the equation y = 3x + 2.
The student is asking for the equation of a line that is perpendicular to a given line and passes through a specific point. The given line has the equation
y = -1/3x - 1. Because perpendicular lines have slopes that are negative reciprocals of each other, the slope of the line we're looking for is 3. Using the point-slope form of the equation of a line, we plug in the slope and the coordinates of the point (1,5) to get
y - 5 = 3(x - 1).
Simplifying this equation gives us the standard form of the line:
y = 3x + 2.
