3x+-6+2 > = 5x -8......can someone please solve this
Answer:
x ≤ 2
Step-by-step explanation:
If you referencing ">=" as greater than or equal to, follow the solution below:
Solve:
3x - 6 + 2 ≥ 5x - 8
Combine like terms.
3x - 4 ≥ 5x - 8
Subtract 5x from both sides.
-2x - 4 ≥ -8
Add 4 to both sides.
-2x ≥ -4
Divide both sides by -2, while flipping the inequality as well since you're dividing by a negative number.
x ≤ 2
Your answer would be x ≤ 2
One way to show that two triangles are similar is to show that ______.

A total of 54 adults and students show up for the play. Adult tickets cost $8 and kid tickets cost $5 and the total money collected
was $360. How many of each type of ticket were sold?
It’s using substitution or elimination to get a number for kids and adults
Answer:
30 adult tickets and 24 kid tickets
Step-by-step explanation:
set up equations
x=adult tickets
y=kid tickets
x(adult tickets)+y(kid tickets)=54(people in total)
x+y=54
$8x+$5y=$360
$8 per ticket for adults
$5 per ticket for kids
total of $360 earned
8x+5y=360
↓
x+y=54
8x+5y=360
solve by elimination or substitution or even graph to get
(x,y)=(30,24)
x=30
y=24

At the store, beef was $73.70 for 5 pounds. If you bought 15 pounds, how much would it cost?
Answer:
$221.1
Step-by-step explanation:
Divide 73.70 by 5 pounds so that you can get the price of 1 pound beef
After diving the price for one pound of beef is $14.74.
Now, you have the price of 1 pound beef, you can just multiply it with 15 pounds.
15 x 14.74 = 221.1
Answer:
$221.1
Step-by-step explanation:

There are five members in a family and the average mass is 42.5 kg. What is the total mass? Please help me.
Answer:
the total mass is 212.5 kg
Step-by-step explanation:
The computation of the total mass is as follows;
Given that
Number of family members = 5
And, the average mass is 42.5 kg
Now based on the above information
The total mass is
= Number of family members × average mass
= 5 × 42.5 kg
= 212.5 kg
Hence, the total mass is 212.5 kg
Jenny will choose between two restaurants to purchase pizzas for her party. The first restaurant charges a delivery fee of $6 for the entire purchase and 12 per pizza. The second restaurant has no delivery fee and charges 14 per pizza.
Answer:
The second one
Step-by-step explanation:
The second one because if you compare 12+6=18 to 14 the better buy is the second one because 14 is less than 18

The formula for the circumference of a circle is c=2pir where r is the radius and c is the circumference. The equation r is r=c/2pi
Answer:
r = 8
Step-by-step explanation:
The circumference of a circle is given by :
[tex]C=2\pi r[/tex] ...(1)
We need to find the value of r when C = 16π
Solving equation (1)
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{16\pi}{2\pi}\\\\r=8[/tex]
So, the value of r is 8. Hence, the correct option is (b).
Mark uses 10 cups of apple juice and 16 cups of orange juice to make fruit punch. Deon uses an equivalent ratio of apple juice to orange juice when he makes fruit punch. Which ratio of apple juice to orange juice could Deon use?
Given that,
No of cups of Apple juice = 10
No of cups of Orange juice = 16
Solution,
The ratio of Apple juice to the Orange juice will be :
[tex]R=\dfrac{10}{16}[/tex] ....(1)
For equivalent fraction, multiply both numerator and denominator by 2 such that,
[tex]R=\dfrac{10\times 2}{16\times 2}\\\\=\dfrac{20}{32}[/tex]
Dividing both numerator and denominator 2 such that,
[tex]R=\dfrac{10/2}{16/2}\\\\=\dfrac{5}{8}[/tex]
So, the required ratio is 5/8.

Prove that 3+2 root 3 is irrational
Answer:
Hi friend,
Let 3+2√3 is a rational number.
A rational number can be written in the form of p/q.
3+2√3=p/q
√3=p/2q-3
√3=p-6q/2q
p,q are integers then (p-6q)/2q is a rational number.
But this contradicts the fact that √3 is an irrational number.
So,our statement supposed is false.
Therefore,3+2√3 is an irrational number.
Step-by-step explanation:
Answer:
in the explanation
Step-by-step explanation:
The sqrt of 3 is irrational. Any rational number multiplied or divided with an irrational number is also irrational (2 root 3). It's the same for addition and subtraction, any rational number added or subtracted from an irrational number is also irrational (2 + root 2).

For her parents' anniversary party, Sarah is considering using one of two venues. A hotel in Booneville will cost $904 for a reservation, plus $86 per person. A restaurant in the same city will cost $89 per person, in addition to $901 for the reservation. In order to make the best decision, Sarah figures out how many attendees it would take to have the venues cost the same amount. How many attendees would that be? What would the total cost be?
Answer:
x = 1
$990
Step-by-step explanation:
First you want to write the linear equations for both scenarios
in the first scenario hotel:
y = 86x + 904 where x = # of people, y = total cost
in the second scenario restaurant:
y= 89x + 901
now you want to set them equal to each other since you want to know how many people (x) will be needed to make total costs equal.
86x + 904 = 89x + 901
subtract 86x on both sides to move all x terms on the right
904 = 3x + 901
subtract 901 on both sides to move numbers to the left
3 = 3x
divide both sides by 3
1 = x or x=1
So it would take 1 attendee.
Now plug in x=1 into either equation to find the total cost that is the same.
y = 86(1) + 904
= 86 + 904
= $990

Find the unit rate (constant of proportionality) for Bobby.
Use (2, 1) and (4.) to find the constant of proportionality.
Enter your answer in the edit fields and then click Check Answer
It is 2 by 20 and 4 by 40
Answer:
Use the formula r = d/t. Your rate is 24 miles divided by 2 hours, so: r = 24 miles ÷ 2 hours = 12 miles per hour. Now let's say you rode your bike at a rate of 10 miles per hour for 4 hours.
