Answer:
C
Step-by-step explanation:
So we have the equation:
[tex]3x-7=x+3[/tex]
Subtract x from both sides. The right cancels:
[tex](3x-7)-x=(x+3)-x\\2x-7=3[/tex]
Add 7 to both sides. The left cancels;
[tex](2x-7)+7=(3)+7\\2x=10[/tex]
Divide both sides by 2:
[tex](2x)/2=(10)/2\\x=5[/tex]
So, our answer is C
Answer:
C) x = 5
Step-by-step explanation:
A) 3(-5) - 7 = (-5) + 3
-15 - 7 = (-5) + 3
-23 = (-5) + 3
-23 = -2 (they do not equal the same so no)
B) 3(2) - 7 = (2) + 3
6 - 7 = (2) + 3
-1 = (2) + 3
-1 = 5 (they do not equal the same so no)
C) 3(5) - 7 = (5) + 3
15 - 7 = (5) + 3
8 = (5) + 3
8 = 8 (they equal the same so yes)
D) 3(-2) - 7 = (-2) + 3
-6 - 7 = (-2) + 3
-13 = (-2) + 3
-13 = 1 (they do not equal the same so no)

s - 51 = 12 (same thing as above)
s (-51 + 51) = 12 + 51

65 = x + 7 (same as above)
( 7 - 65 ) = x ( 7 - 7 )

what is a geometric sequence with a first term of 3/4 and a constant ratio of 4
Answer:
Below
Step-by-step explanation:
A geometric sequence is a sequence where you keep multiplying a term by the ratio to generate the next one.
The first term is 3/4
Let n0 = 3/4
The next term is n1.
To get n1 we must multiply n0 by the ratio 4.
● n1 = n0×4
This formula gives us the second term. We need a general one that can generate all the terms of the sequence.
Let S(n) be a term of this sequence.
To get n we have multiplied n0 (the first term) by 4 (the ratio) one or many times. Precisely, n times.
So:
● S(n )= n0 ×4^n
no is 3/4
● S(n)= (3/4) × 4^n
This formula generates any term from this geometric sequence. If you want to calculate the 77th term then just replace n with 77.
Answer:
Step-by-step explanation:
To find the next term, multiply the previous term by constant ratio
a₁ = 3/4
[tex]a_{2}=\frac{3}{4}*4=3*1 = 3\\[/tex]
a₃ = a₂ * constant ratio = 3 * 4 = 12
a₄ = a₃ * constant ratio = 12 *4 = 48
Geometric sequence :
3/4, 3,12, 48, 192,.......

(02.01)Line segment EF has a length of 5 units. It is translated 5 units to the right on a coordinate plane to obtain line segment E'F'. What is the length of E'F'?
5 units
6 units
10 units
25 units
The line segments are translated 2 units to the left to form J'K' and M'N'. Which statement describes J'K' and M'N'?
Line segments J'K' and M'N' do not intersect and are closer together than JK and MN.
Line segments J'K' and M'N' intersect at (−2, 0) and are two times farther apart than JK and MN.
Line segments J'K' and M'N' intersect at (0, −2) and are two times closer together than JK and MN.
Line segments J'K' and M'N' do not intersect and are the same distance apart as JK and MN.
Answer:
The answer is "Option a and Option d".
Step-by-step explanation:
In the given-question, the numbering of the choices was missing so, we define the number after that we define its explanation:
In question 1, the translations were only the axis, which moves in the length of a segment, that doesn't change. Even so, the graph shifts only by growth, that's why the E'F 'duration will be the same as the EF length, which equals to "5 units".
In question 2, both JK and MN shifts to the left two units, and there would be no difference throughout the space between them, that's why the choice "d" will be correct.
A = a+b+c/3 Solve for b this is a literal equation problem please show steps

Step-by-step explanation:
[tex]$A=\frac{a+b+c}{3} $[/tex]
Multiply both sides by 3
[tex]$3A=a+b+c $[/tex]
Add [tex]-b-c[/tex] both sides

if DF = 61 and EF = 18, find DE
The measure of length DE if DF = 61 and EF = 18 is 43
From the question, we are given the following measurement:
DF = 61
EF = 18
Required:
DE
Using the expression to find the measure of DE
DE + EF = DF
Substitute the given values
DE + 18 = 61
Subtract 18 from both sides
DE + 18 - 18 = 61 - 18
DE = 43
Hence the measure of DE is 43

Casey dug a cubical hole to bury a memory box as a time capsule. The volume of the dirt he removed is 729 cubic inches. How many inches deep is the hole?
Answer:
The hole is 9 inches deep
Step-by-step explanation:
Volume of a cubicle hole = a^3
Where a= side edge of the cube
Volume of dirt removed = 729 cubic inches
How many inches deep is the hole
Volume of a cubicle hole = a^3
729 = a^3
Find the cube root of both sides
3√729 = 3√ a^3
9 = a
a= 9 inches
The hole is 9 inches deep
Check:
9^3
=9 *9*9
= 729

1. Pick a sport and name two categorical variables and two numerical variables
Answer:
Football
Categorical variables:
Type of game= Ball game
Governing body= Federation Internacionale de Football Association (FIFA)
Numerical Variables
Number of players in each team= 11
Number of teams involved= 2
Step-by-step explanation:
A categorical variable is data about a subject that tells its category, type or description. It answers the what, when, why, which, and where questions. The game of football is categorized as a ball game and the governing body that supervises it is FIFA. This answers the question of 'Which governing body supervises the game of football?
Numerical variables give details of a subject in terms of figures, or measurements. To answer the question of how many people play the game of football in each team, we state that there are 11 players and the number of teams that can play at the same time is 2.

Answer:
B
Step-by-step explanation:
by a rule of angles in parallel lines we have that
angle 4 + angle 5 =180
so we have
(3x+15)+(2x-10)=180
(3+2)x+(15-10)=180
5x+5=180
5(x+1)=180
x+1=36
x=36-1
x=35
Answer:
B. 35
Step-by-step explanation:
<4 and <5 are supplementary angles and their sum is = 180°
3x + 15 + 2x - 10 = 180 add like terms
5x + 5 = 180
5x = 175
x = 35

The midpoint of MN is point P at (-4, 6). If point M is at (8, -2), what are the coordinates of point N?
O (-16, 14)
O (-10,5)
O (22)
O (6,2)
Answer:
N(- 16, 14 )
Step-by-step explanation:
Given the endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ [tex]\frac{1}{2}[/tex](x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ )
Use this formula and equate to the coordinates of the midpoint P
let the coordinates of N = (x, y ), then
[tex]\frac{1}{2}[/tex](8 + x ) = - 4 ( multiply both sides by 2 )
8 + x = - 8 ( subtract 8 from both sides )
x = - 16
[tex]\frac{1}{2}[/tex] (- 2 + y ) = 6 ( multiply both sides by 2 )
- 2 + y = 12 ( add 2 to both sides )
y = 14
Thus
coordinates of N = (- 16, 14 )

five states in a country have 4 star hotels. Assume the country has 50 states. (a) what fraction of the states can claim at least one four star hotel? (b) how many states do not have a four star hotel (c) write a fraction of states without a four star hotel
Part A:
Since five states have four-star hotels, only those five states can claim at least one four-star hotel and since there are 50 states, we can write this as 5/50 or 1/10.
Part B:
50 - 5 = 45 states don't have a four-star hotel.
Part C:
45/50 or 9/10 of the states do not have a four-star hotel.
Best of Luck!
Answer:
The fraction of states with a four-star hotel 9/10.
The number of states without a four-star hotel is 5
The fraction of states without a four-star hotel is 1/10
NOT 45.

What conditions would determine whether or not two numbers' GCF is equal to one of the original numbers?
Step-by-step explanation:
GCF is literally abbreviated to "Greatest Common Factor". In order for two numbers to have the same GCF they must have a number that they both could be multiplied by.
I also suggest using a factor tree. Super useful when figuring out the rest of the common factors.
