What is 6 - 2 over 3 (x + 5) = 4x algebraically
Answer: x = 4/7
Explanation and steps is in the image below.
The solution to the given equation 6 - 2(x + 5)/3 = 4x is x = 4 /7.
What is the equation?The equation is defined as an algebraic statement that has a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question
6 - 2(x + 5)/3 = 4x
Apply the distributive property of multiplication,
6 - (2x + 10)/3 = 4x
(2x + 10)/3 + 4x = 6
2x/3 + 10/3 + 4x = 6
2x/3 + 4x = 6 - 10/3
Take the LCM in the above equation,
14x/3 = 8/3
14x = 8
x = 8 / 14
x = 4 /7
Thus, the solution to the given equation 6 - 2(x + 5)/3 = 4x is x = 4 /7.

1 2/3 yards of chain cost 9.00.
How much money for 1 yard
Alright nevermind, imma delete this answer.
Answer: $5.40
Step-by-step explanation:
1 and 2/3 yards costs $9
5/3 yards costs $9 <--- changes 1 and 2/3 to improper
5 * 1/3 yards costs $9 <---- 5/3 = 5 * 1/3
1/3 yard costs $9/5 = $1.80 <--- divides the ratio by 5
1 yard costs $1.80 * 3 = $5.40

Translate the inequality and solve. Three times a number is less than or equal to six.
Answer:
x ≤ 2
Step-by-step explanation:
We can write out the inequality as: 3(x) ≤ 6
You have to divide 3 from both sides, so x ≤ 6/3 which is x ≤ 2.

a triangle has side lengths 6,11 and 14. Is it acute, obtuse or right
Answer:
acute
Step-by-step explanation:
sorry if im wrong how I did it is on a paper or create a picture in your mind have a good night if you have a question please ask away in the comments
This triangle is obtuse.
What is right triangle?Triangle is defined as a triangle which one angle is a right angle or two sides are perpendicular.
Let a = 6 ,b = 11 & c = 14 be the sides of a traingle, c being longest of three
If a²+b²=c² it is right angled,
If a²+b²>c² it is acute,
If a²+b²<c² it is abtuse,
Substitue the values of a, b and c,
a²+b²= 6²+11² = 157
c² = 14² = 196
Since a²+b²<c²
Hence, this triangle is obtuse.

A rectangle and an equilateral triangle have the same perimeter. The perimeter of the rectangle is 6 ( 1 2 x + 5 ) inches. The perimeter of the triangle is 4 ( x − 2 ) inches. What is the perimeter of each figure?
Answer:
-328/34
Step-by-step explanation:
Here,
Perimeter of rectangle = 6(12x+5)
Perimeter of equilateral triangle = 4(x-2)
Since they are equal, 6(12x+5) = 4(x-2)
or, 72x + 30 = 4x - 8
or, 68x = -38
or, x= -38/68 or -19/34
Now,
Area of triangle ( or rectangle whichever you prefer)
= 4* -19/34 - 8
= -76/34 - 8
= - 328/34
what is y equal to 2x + 4y = -18
Slope = -1/2
Y intercept = -9/2
=====================================================
Work Shown:
2x + 4y = -18
2(x+2y) = -18 .... factor out 2
x+2y = -18/2 .... divide both sides by 2
x+2y = -9
2y = -9-x .... subtract x from both sides
2y = -x-9
y = (-x-9)/2 ... divide both sides by 2
y = (-x/2) - (9/2) ... break up the fraction
y = (-1/2)x - 9/2
The last equation is in slope intercept form y = mx+b with m = -1/2 as the slope and b = -9/2 as the y intercept.
Answer:
Step-by-step explanation:
2x + 4y = -18
2(x+2y) = -18 .... factor out 2
x+2y = -18/2 .... divide both sides by 2
x+2y = -9
2y = -9-x .... subtract x from both sides
2y = -x-9
y = (-x-9)/2 ... divide both sides by 2
y = (-x/2) - (9/2) ... break up the fraction
y = (-1/2)x - 9/2
The last equation is in slope intercept form y = mx+b with m = -1/2 as the slope and b = -9/2 as the y intercept.

Step-by-step explanation:
if u pluged in 4 for t to the equation u would get 1000 which is the correct amount
hope this helped!
Answer:
a = 250t or Answer D
Step-by-step explanation:
Y = mx+b
m = (y2-y1)/(x2-x1)
m = (2500-100)/(10-4)
m = 1500/6 = 250
y = 250x+0
y = 250x
Scientists are preparing two satellites to be launched. The equation y=8200xy=8200x represents the number of miles, yy, that the satellite, Space Explorer B, flies in xx hours. The satellite, Space Explorer A, flies 28800 miles in 24 hours. How many fewer miles does Space Explorer A travel in one hour than Space Explorer B?
Answer:
It flies 380 miles fewer
Step-by-step explanation:
The correct question is as follows;
Scientists are preparing two satellites to be launched. The equation y=820x represents the number of miles, y, that the satellite, Space Explorer B, flies in x hours. The satellite, Space Explorer A, flies 28800 miles in 24 hours. How many fewer miles does Space Explorer A travel in one hour than Space Explorer B?
Solution;
For explorer B
The equation is;
y = 8200x
This mean that in 1 hour, it flies 820 miles
For explorer A
28,800 miles in 24 hours
In one hour, we have 28,800/24 = 1,200 miles
The number of fewer miles that explorer A travels will be ;
1200 miles - 820 miles = 380 miles fewer

Bethany and Aidan each have candy bars that are the same size and shape. Bethany's candy bar is marked so that it can be broken into equal parts. Aidan's candy bar is marked to that it can be broken into equal parts. Bethany ate pieces of her candy bar. Aidan also ate pieces of his candy. What is this problem about?
Answer:
Step-by-step explanation:
This problem is most likely about what percentage of the candy does each individual have left. Since the phrase is explaining that each ones candy bar is the same size and can be broken into equally divided pieces then it is most likely about figuring out which one of the individual's has more candy left over when compared to the other's candy. This is possible since both candies are the same size but more information would be needed.
