Answer:
Options (A), (C) and (E)
Step-by-step explanation:
Given equation is,
-3x + 7 = -5 + x
-3x + 7 - 7 = -5 + x - 7
-3x = -5 + x - 7 Option (C)
-3x = x - 12
-3x - x = -12
-4x = -12 Option (A)
4x = 12 Option (E)
[tex]\frac{4x}{4}=\frac{12}{4}[/tex]
x = 3
Therefore, Options (A), (C) and (E) are the correct options.

Answer:
(f o g)(x) = 4x^2 - 8
Step-by-step explanation:
(f o g)(x) = f(g(x))
f(x) = x^2 - 8
g(x) = 2x
f(g(x))
f(2x) = (2x)^2 - 8
= 4x^2 - 8
(f o g)(x) = 4x^2 - 8

3x+1+10x=x+4
Answer:
x=¼
Step-by-step explanation:
3x+1+10x=x+4 (Group like terms )
3x+10x-x=4-1
12x=3(Divide both sides by 12)
[tex] \frac{12x}{12} = \frac{3}{12} [/tex]

Find the values of x and y in the diagram.
Answer:
x = 18
y = 6
Step-by-step explanation:
In triangle UTR, measures of all angles are equal (60°). (given)
Therefore, it is an equilateral triangle.
So, it's sides will also be equal.
In triangle TRS, m angle T = m angle S
So, RT = RS = 11 (sides opposite to the equal angles are equal)
In triangle URT,
UT = RT (sides of equilateral triangle)
x - 7 = 11
x = 11 + 7
x = 18
In triangle TRS,
m angle T = m angle S = 5y°
m angle R = 180° - 60° = 120° (Linear pair angles)
5y° + 5y° + 120° = 180°
10y° = 180° - 120°
10y° = 60°
y = 60/10
y = 6

if the price of aluminum cans is 32 cents per pound and it takes 32 cans to make 1 pound how many cans do I need to make $100?
Answer:
1,000 cans
Step-by-step explanation:
Since there are 32 cans per pound and each pound is 32 cents. You divide 32/32 which tells you each can is 1 cent. So 100 dollars divided by 1 cent is 1,000 cents or 1,000 cans since each can is 1 cent.
Answer:
1000 can

In continuous type of series, for finding mean, which amongst the
following is considered as X variable value?
Select one:
O a lower limit of the interval
O b. upper limit of the interval
O c. mid point of the interval
O d. none of these
In the continuous type of series for determining the mean, the midpoint of the interval should be considered as the X variable value.
Continuous Series is the series where all types of class intervals with the frequency should be listed in the table form. Here all the class intervals do not contain a similar frequency.
For determining the mean, the direct method should be used in which the midpoint from X should be measured and the same should be relevant.
So, the following should not be relevant for determining the mean:
The lower limit and upper limit of the interval.Therefore In the continuous type of series for determining the mean, the midpoint of the interval should be considered as X variable value.

How much charge is needed to repel another charge of 9.9 x 10^-6 N when they are 200m apart? Please help meee I really can't understand Coulomb's Law : (
Answer:
The charge needed will be [tex]q=6.6\: \mu C[/tex]
Step-by-step explanation:
The equation of the electric force is given by:
[tex]F=k\frac{qQ}{r^{2}}[/tex]
We have the force [tex]F = 9.9 10^{-6}\: N[/tex] and the distance r = 200. k is the Coulomb constant. Q and q are the charges.
We assume we have the same charge of the particles, so we have:
[tex]q^{2}=\frac{Fr^{2}}{k}[/tex]
[tex]q^{2}=\frac{9.9*10^{-6}200^{2}}{9*10^{9}}[/tex]
[tex]q=6.6*10^{-6}\: C[/tex]
Therefore, the charge needed will be [tex]q=6.6\: \mu C[/tex]
