Answer:
(x ,y)= (1/3, -4/3)
Step-by-step explanation:
simplify
y = -4x
x + 2y + 1 = -4x
multiply both sides
4x + y = 0
5 x + 2y = -1
eliminate one variable
-8x - 2y = 0
5x + 2y = -1
divide
-3x = -1
x = 1/3
possible solution
y= -4/3
check the solution
(x, y) = (1/3, -4/3)
simplify
-4/3 = 1/3 + 2 x (-4/3) + 1 = -4 x 1/3
place in order
-4/3 = -4/3 = -4/3
simplify 1/3x + 1/4 - 2/3x
Answer: ___
-1/3x + 1/4
Answer:
x/3 +1/4+-2x/3
Step-by-step explanation:
Combine multiplied terms into a single fraction
1/3x+1/4-1*2/3*x
1x/3+1/4-1*2/3*x
Multiply by 1- 1x/3+1/4-1*2/3*x x/3+1/4-1*2/3*x
Multiply the numbers- x/3+1/4-1*2/3*x x/3+1/4-2/3x
Combine multiplied terms into a single fraction-
x/3 +1/4-2/3x x/3+1/4+-2x/3
SOLUTION:
x/3 +1/4+-2x/3

Answer:
2.73 8.75
Step-by-step explanation:
n = 1
1 (DOUBLE) = 1+1 = 2
2 +3/4 = 1.5
1.5 +2 = 3.5
3.5 x 0.22 = 0.77
3.5 - 0.77 = 2.73
n = 1
1 + 3/4 = 1 + 0.75 = 1.75
1.75 (DOUBLE) = 3.5
3.5 x 2 1/2 = 8.75

Answer:
it would be A
Step-by-step explanation:
the "<" (less sign) would mean B is less than A which is less than D which is less than C. if it is asking to put in the order which is greater than, there would need to be a ">" (greater sign). since there are no greater than signs, the process is flipped to be D is less than C which is less than A which is less than B meaning B is the greatest increasing likelihood, hope this helps :)

Im so glad I could help! I hope you pick my answer as the Brainliest!
Answer:
Step-by-step explanation:
Since this is a test, I'll give a hint.
This problem can be a little confusing, but thats ok! The problem is trying to make two models, (each model is a number) and asking you to find what the addition sentence is.
If that makes you confused, then that's probably the right response! The first thing you would need to know is what are they dividing the whole circles of? Thirds? Seconds? Sixths?
You would then need to know how many whole numbers are there. "Whole numbers" are basscially fully shaded circles.
Hope this helps!

I REALLY NEED A GOOD GRADE ON THISSS
Answer:
is this a test
Step-by-step explanation:
Answer:
1. No Solution, 2. Unique Solution, 3. Infinitely Many Solutions
Step-by-step explanation:
1. If two lines are parallel, they share no common points, and no answers.
2. y = 3x + 4 and y = 1/2x + 5 are not parallel and not equivalent, therefore, they have one solution.
3. Simplified, the two equations are z + 2y = 10 and z + 2y = 10, therefore they are equivalent and they have solutions for as far as the line extends, which is infinitely.

3.17, because there are about 1.056 quarts in one liter.
1.056 times 3 = 3.168, which, rounded to the nearest hundredth, is 3.17.
hope this help :)
After rounding off the obtained value, the value obtained in quarts will be equal to 3.17 qt.
What is rounding off values?The act of simplifying a number so that its value remains near to what it was is known as rounding. The outcome of rounding off a figure is less precise but simpler to utilize. They directly involve if a number's digits are taken into account while rounding it.
As per the given information in the question,
As we know,
1 liter = 1.057 quarts
Then, the number of quarts in 3 L will be equal to,

What is the value of x?
3(-9 - 4x) - 4= 8x - 9(x + 12)
Answer:
x=7
Step-by-step explanation:
uhhh yes
Answer:
x=7
Step-by-step explanation:
3(-9 - 4x) - 4= 8x - 9(x + 12)
distribute
-27-12x-4=8x-9x-108
combine like terms
-31-12x=-x-108
add x to both sides
-31-12x+x-108
add 31 to both sides
-12x+x=-108+31
combine like terms
-11x=-77
divide both sides by -11
x=7
Micheal is buying Presents for a gift exchange for his four friends. He would like to spend less than $160 total. On average, how much can he spend on each person? Write out the Inequality as well.
Answer:
Micheal will spent 40 $ on each of his friends
Step-by-step explanation:
160$÷4=40$
why because there is 160 dollars to spend and there are 4 friends now you need to divide that to get the amount of money you need.
Answer:
x≤40. He can spend about $40 on each friend
Step-by-step explanation:
I got this because a number x is the amount of money he can spend on a friend on average. The inequality is then written like 4x≤160. You then try to get "x" on its own by dividing both sides by 4 (both sides being 4x and 160). then you get the average amount Michael can spend on his friends.

Jenna rents 4 identical storage lockers. each locker is shaped like a cube. the four lockers are arranged in a row, as shown.
The total volume of all four lockers is 4s^3
What is the total volume of all four lockers if one side of a locker is 2 feet long.?
ANSWER ASAP
Answer:
║∦║→→→→Hello :D←←←←║∦║
Your answer should be:
4s^3
Step-by-step explanation:
Hope this helped!
Have a great day!We want to get the total volume of the four lockers when one side of the locker is 2 ft long. The total volume of the four lockers is 32 ft^3
First, we know that the total volume is given by:
V = 4*s^3
Now, lockers are shaped like cubes, thus, if one of its sides measures 2ft, then all of the sides measure 2ft.
That volume equation says that the volume of the four lockers is equal to four times the volume of a cube of side length s.
In this case, we just have s = 2ft, replacing that we get:
V = 4*(2ft)^3 = 32ft^3
The total volume of the four lockers is 32 ft^3
