Answer:
x = 8
Step-by-step explanation:
[tex] - \frac{1}{2} x + 3 = - x + 7[/tex]
Collect like terms and simplify
[tex] - \frac{1}{2} x + x = 7 - 3 \\ \frac{1}{2} x = 4[/tex]
Cross Multiply
[tex]x \times 1 = 2 \times 4 \\ x = 8[/tex]
Answer:
x = 8
Step-by-step explanation:
-1/2x+3=-x+7
Add x to each side
-1/2x+x+3=-x+x+7
1/2x+3=7
Subtract 3 from each side
1/2x +3-3=7-3
1/2x=4
Multiply by 2
1/2x*2 = 4*2
x = 8
What modifications did kepler make to copernicus’s model? select two options. planetary orbits are elliptical. planets closer to the sun move faster. planets spin in an epicycle while orbiting earth. venus has phases due to its orbiting of the sun. earth’s rotation causes the rising and setting of the sun.
The modifications did Kepler make to Copernicus’s model are planetary orbits are elliptical (A) and Earth’s rotation causes the rising and setting of the sun (E).
What are the laws of Kepler?There are three laws, made by the Kepler, to explain the motion of the planet around the sun.
First Law-According to this law, all the planets moves in the elliptical orbits. The center of this orbital path is the Sun. Thus Planetary orbits are elliptical. Second Law-The planet moves in elliptical orbit. The line of planet and sun sweeps out equal mass in equal time.Third Law-The square of the period of a planet to complete one path of electrical orbit is directly proportional to the cubes of semi-major axis of their orbit.Earth’s rotation causes the rising and setting of the sun because of the earth's rotation on its axis.
Hence, the modifications did Kepler make to Copernicus’s model are planetary orbits are elliptical (A) and Earth’s rotation causes the rising and setting of the sun (E).

MQ = 2x+2
QO= 3x-10
find x
(it’s a rhombus)
Answer:
2x+2=3x-10
2+10=3x-2x
x= 12
Answer:
x = 12
Step-by-step explanation:
The diagonals PN and MO are perpendicular bisectors of each other, thus
QO = MQ , substitute values
3x - 10 = 2x + 2 ( subtract 2x from both sides )
x - 10 = 2 ( add 10 to both sides )
x = 12

A rental car company charges $68.64 per day to rent a car and $0.12 for every mile driven Jackson wants to rent a car knowing that he plans to drive 500 miles he has at most $210 to spend what is the maximum amount of number of days that Jackson can rent a car while staying with his budget
Answer:
maximum amount of number of days that Jackson can rent a car while staying with his budget is 2 days
Step-by-step explanation:
first of all find the amount of money he will spend for 500 miles
in this case we multiply 0.12 by 500
=> 0.12 × 500
=> 60
subtract 60 from the money budgeted which is $210
=> $210 - 60
=> 150
divide 150 by the company charges per day which is dollars 68.64
=> 150 ÷ 68.64
divide 150 by 68.64
=> 2.185314685314685
approximately
=> 2 days
Answer:
2

Find the distance between the two points in simplest radical form (3, 8) and (5, - 1)
Answer:
[tex]d = \sqrt{85}[/tex]
Step-by-step explanation:
Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in the 2 coordinates into the distance formula to find distance d:
[tex]d = \sqrt{(5-3)^2+(-1-8)^2}[/tex]
[tex]d = \sqrt{(2)^2+(-9)^2}[/tex]
[tex]d = \sqrt{4+81}[/tex]

Solution for 5 divided by 3
✍️See below how to solve this division manually.
5 divided by 3 - Long Division Solution
The solution below uses the "Long Division With Remainders Method". It is one of two existing methods of doing long division.
Start by setting the divisor 3 on the left side and the dividend 5 on the right:
1 ⇐ Quotient
―
3)5 ⇐ Dividend
3
-
2 ⇐ Remainder
The result of the division of 5 divided by 3 is 1.6666666666666667, as a decimal number.
5/3 as a mixed number
5 divided by 3 equals to the mixed number 1 2

this is very simple actually! i can teach you:
(x,y)
so if you are counting left or right it goes to the x. for example, if you want to find J, you go to the black dot that says J and count starting from 0 or by looking at the x axis.
if you are counting up or down you go to (input the value) the y. if you want to find J for example, (the y coordinate) you go to the black dot and you count starting from 0. usually it will have the points -5 -4 -3 -2 -1 0 1 2 3 4 5 but in your problem it does not have so you just have to count carefully.
i will go search for what K' or J' means

what is 0.75x – 100 ≤ 80
Answer: X is less than or equal to 240
The solution to the inequality 0.75x - 100 ≤ 80 is x ≤ 240.
Given is an inequality what is 0.75x – 100 ≤ 80, we need to solve it,
To solve the inequality 0.75x - 100 ≤ 80, we can follow these steps:
1. First, let's isolate the variable x by adding 100 to both sides of the inequality:
0.75x - 100 + 100 ≤ 80 + 100
0.75x ≤ 180
2. Next, we can divide both sides of the inequality by 0.75 to solve for x:
(0.75x) / 0.75 ≤ 180 / 0.75
x ≤ 240
Therefore, any value of x that is less than or equal to 240 will satisfy the inequality.
Therefore, the solution to the inequality 0.75x - 100 ≤ 80 is x ≤ 240.
