Answer:
A, 35
Step-by-step explanation:
9x - 1 = 2x + 27
7x - 1 = 27
7x = 28
7x/7 = 28/7
x = 4
and now we plug it in,
9x - 1
9(4) - 1
36 - 1
35
and for the second point,
2x+27
2(4)+27
8+27
35

Hi. I need help with this question (see image). Please show workings.
Answer:
[tex]\frac{dy}{dx}[/tex] = - [tex]\frac{18x}{(3x^2+1)^4}[/tex]
Step-by-step explanation:
Differentiate using the chain rule
Given
y = f(g(x)) , then
[tex]\frac{dy}{dx}[/tex] = f'(g(x) × g'(x)
Given
y = [tex]\frac{1}{(3x^2+1)^3}[/tex] = [tex](3x^2+1)^{-3}[/tex] , then
[tex]\frac{dy}{dx}[/tex] = - 3[tex](3x^2+1)^{-4}[/tex] × [tex]\frac{d}{dx}[/tex] (3x² + 1 )
= - 3[tex](3x^2+1)^{-4}[/tex] × 6x
= - [tex]\frac{18x}{(3x^2+1)^{4} }[/tex]
Which best represents the amount of water in the bottle that she did not drink?
Answer:
D. 13/20
Step-by-step explanation:
She did not drink 65/100, so you simplify that and you get 13/20
Answer: 13/20
Step-by-step explanation:
This question is based around conversions; you should know how to convert between percentages and fractions.
The question says that Lakisha drank 35% of the water contents. This means that she did not drink 65% (100% - 35% = 65%)
Now here is where the conversion comes in.
65% as a fraction is 65/100.
However, this isn't an option, so you have to simplify the fraction by dividing by 5.
65 / 5 = 13
100 / 5 = 20
Therefore, the answer is 13/20
Hope this helps :)

1. A
group of 20 lobour can complete a
Work in 15 days what oumber of Lobo
to be added to complete that work in
12 days. (Ans-5 workers)
Answer:
5 more man should be added
Step-by-step explanation:
Inverse Proportion
The time needed to complete a job is inversely proportional to the number of men working on it.
It means the more men working, the less time needed to complete the job.
We know 20 men can complete the job in 15 days. If the job must be completed in 12 days, then more men are needed, thus the number of men needed is:
[tex]20*\frac{15}{12}=\frac{300}{12}=25[/tex]
25 men are needed which means 25-20 = 5 more men should be added.
5 more man should be added

Brett and Greg each want to run for president of their school’s student body Council. in order to do so, they must collect a certain number of signatures and get a nomination. So far, Brett has 10 signatures, and Greg has 20. Brett is collecting signatures at an average rate of five per day, whereas Greg is averaging three signatures every day. Assuming that their rate of collection stays the same, eventually the two will have collected the same number of signatures. How many signatures will they both have?
Answer:
they need 130 per day signature
I need help pls asap
Answer:
Step-by-step explanation:
first we are told that side and ae and a f are the same
so that means one side of each triangle is the same
next we are told that that the lines coming off of those sides are both right angles. so we know these are both right triangles
and b/c both of those angle are right angles... the sides ab and ac have to also be the same length.. or the angle could not be a right angle
therefore since two sides are the same length then all 3 must be the same lengths
and b/c all three are the same these two triangles are the same .. congruent

Marie pays $2.50 for 5 pecils. Use the drop down menu to explain how to determine and use constant of proportionality, in dollars per pencil, that relates these values
Answer:
$0.5
Step-by-step explanation:
Given data
Cost of 5 pencils= $2.50
Required
The cost per pencil
The cost per pencil is
Cost of 5 pencils divided by 5
=2.5/5
=$0.5
This is the constant of proportionality
For any number of pencils x
The cost is
Cost =0.5x
Hence the cost of one pencil is $0.5

-w/6 + 9 = 2
PLZ ANSWER TODAY AND FAST I NEED IT RIGHT NOW
Answer:
w = 42
Step-by-step explanation:
-w/6 + 9 = 2
subtract 9 from both sides
-w/6 + 9 - 9 = 2 - 9
-w/6 = 2 - 9
-w/6 = -7
multiply both sides by -6
-w/6 * -6 = -7 * -6
w = -7 * -6
w = 42

The slope of the line is: m = 1
Step-by-step explanation:
From the attached graph, we take the two points
(0, 5) (-5, 0)Now, determining the slope between the points (0, 5) and (-5, 0)
Slope = Rise / Run
Please also check the attached diagram to check Rise and Run.

If a 18 ft tall statue casts a 12 ft Long shadow, then how long is the shadow that a 3 ft tall baby elephant casts
Answer:
2 feet
Step-by-step explanation:
This is because you have to use ratios:
18:12 :: 3:x
you can then figure out 18/12=1.5, so you have to figure out what what 1/1.5 or 2/3 of what 3 is. you then multiply 3 by 2/3 and get 2 feet
Answer:
2 ft
Step-by-step explanation:
use cross multiplication
12 is to 18 as x is to 3
12 / 18 = x / 3
12 × 3 = 18x
now solve for x
36 = 18x
divide by 18
2 = x
So a 3 ft baby elephant casts a 2 ft shadow
