Answer:
2c - 10
Step-by-step explanation:
When you combine the like terms of the expression c+c-10, you get 2c-10.
Therefore, 2c - 10 is equivalent to c + c - 10.
c + c - 10 → 2c - 10.

A candle on a table is 6 inches tall and burns at a rate of .8 inches per hour. How many hours will it take for the candle to burn down to a height of 1.2 inches?
Answer:
6 hours
Step-by-step explanation:
6 inches burns at rate .8 inches in 1 hour
to be 1.2 inches has to burn 6 -1.2 = 4.8 inches of the candle
4.8 inches / .8 inches in 1 hour = 6 hours
Solve for X please help
Answer:
x = 10
Step-by-step explanation:
First square both sides of the equation...
[tex]2\sqrt{x + 8} = 3\sqrt{x - 2} \\(2\sqrt{x + 8})^{2} = (3\sqrt{x - 2})^{2} \\ 4(x + 8) = 9(x - 2)\\4x + 32 = 9x - 18\\-5x = -50\\x = 10[/tex]
The ages of George and Genemy are in ratio 5:7 . Four years from now the ratio of their ages will be 3:4 .Find their present ages.
Answer:
Below in bold.
Step-by-step explanation:
Let x be George's age and y be Genemy's age.
x/y = 5/7
(x + 4)/ (y + 4) = 3/4
From equation 1, y = 7x/5 = 1.4x so substituting in equation 2 :
(x + 4)/ (1.4x + 4) = 3/4
3(1.4x + 4) = 4(x + 4)
4.2x + 12 = 4x + 16
0.2x = 16 -12 = 4
x = 4/0.2 = 20 = George's age.
So y = 1.4x = 1.4 * 20 = 28 = Genemy's age.
Can someone please help me with math.
What is the equation of a line, in slope intercept form, that has a y-intercept of -1 and a slope
Answer:
y = 5x - 1
Step-by-step explanation:
Given the following data;
Intercept = -1
Slope = 5
To find the equation of line;
Equation of straight line is y = mx + c
Where;
m is the slope.
x and y are the points
c is the intercept.
Substituting the values in order to find the intercept, we have;
y = mx + 1
y = 5x - 1
I needs your helps please :) ty
Answer:
so the answer could either be
Yes. as elevation increases, the temp decreases
but..
there is also no trend coz the points are scattered i.e the temp
as the elevation is increasing the temp does vary.
so My final answer would be no, there is not a trend

At noon three students, Abby, Ben, and Cassie, are standing so that Abby is m west of Ben and Cassie is m east of Ben. While Ben stays in his initial position, Abby begins walking south at a constant rate of m/min and Cassie begins walking north at a constant rate of m/min. In how many minutes will the distance between Cassie and Ben be twice the distance between Abby and Ben?
Answer:
Let represent the number of minutes until Cassie’s distance to Ben is twice that of Abby’s distance to Ben. In minutes Abby will walk m and Cassie will walk m. The following diagram contains the information showing Abby’s position, , Ben’s position, , and Cassie’s position, , at time .
A right-angled triangle is formed by joining Abby's initial position to points A and B. Its hypotenuse is A B and its other sides are of length 100 and 20 times t. Another right-angled triangle is formed by joining Cassie's initial position to points C and B. Its hypotenuse is B C and its other sides are of length 160 and 41 time. Represent Abby, Ben and Cassie’s respective positions at noon as points on the -axis so that Ben is positioned at the origin , Abby is positioned units left of Ben at and Cassie is positioned units right of Ben at .
solution 2
Let represent the number of minutes until Cassie’s distance to Ben is twice that of Abby’s distance to Ben.
In minutes Abby will walk south m to the point . In minutes Cassie will walk north m to the pointTherefore, in
minutes ( minutes seconds), Cassie’s distance to Ben will be twice that of Abby’s distance to Ben. .

Volume of Composite Figures
Answer:
612 pi m^3
Step-by-step explanation:
Volume of the cylinder = 576 pi m^3
volume of the cone = (radius^2 x pi x height)/3 = (6^2 x pi x 3)/3 = 36 pi m^3
total volume = 576 pi + 36 pi = 612 pi m^3

Need help with this question
In picture above
Answer:
Solution given:
Cos -θ:[tex]\frac{\sqrt{3}}{4}[/tex]
since cos -θ=Cos θ
Cos θ :[tex] \frac{\sqrt{3}}{4} [/tex]
[tex]\frac{\sqrt{b}}{h} [/tex]=:[tex] \frac{\sqrt{3}}{4} [/tex]
b=[tex]\sqrt{3} [/tex]
h=4
p=[tex] \sqrt{4²-(\sqrt{3})²} [/tex]=[tex] \sqrt{13}[/tex]
So
Sin θ=[tex]\frac{p}{h} [/tex]=[tex]\frac{\sqrt{13}}{4} [/tex]
So third one is a required answer.
Which solution correctly solves the problem 6x - 19 = 77? plz help
A.
B.
C.
D.
Answer:
D
Step-by-step explanation:
in order to get the process of solving the equation, we need to solve it.
our goal to solve the equation 6x-19=77 is to isolate the variable onto one side, and have the numbers (value of x) on the other
we have the equation:
6x-19=77
first, we can get rid of -19 on the left side and leave 6x on that side by adding 19 to both sides (-19+19=0).
The reason why we're adding 19 to both sides is because if we do something to one side, we have to do it to the other side to make sure the value of the equation stays the same.
6x-19= 77
+19 +19
_________
6x=96
now, we do have the variables on one side and the numbers on another side, but we aren't done yet, as we want the value of x by itself
divide by 6 on both sides
x=16 (because 6x/6=1x, or x. 96/6=16).
the option of D shows the same method I did and has the correct answer as well.
This is what was given for D:
6x-19=77
6x-19+19=77+19
6x=96
6x/6=96/6
x=16
(same thing I did)
So D is the correct answer.
Hope this helps!
HELP ME WITH THIS PLEASE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
The answer is 5
hope it helps
Answer:
n = 5 units
Step-by-step explanation:
We can solve this using 2 different equations which lead to the same answer:
Equation #1: Sin(30) = n/10
=>Sin(30) * 10 = n
=> 5 = n
Equation #2: Cos(60) = n/10
=> Cos(60) * 10 = n
=> 5 = n
If a number is a whole number, it is in it's simplest radical form, therefore; n = 5 units is the correct answer
Hope this helps!
