What value of x is in the solution set of 2x - 3 > 11 - 5x?
Answer:
x>2
Step-by-step explanation:
first you collect like terms together so ,
u bring 5x to the other side to be 2x+5x-3>11 ,
you take -3 to the other side to be 2x+5x>11+3
therefore it will be 7x>14 ,so you divide both sides with 7 to get
x>2
Answer:
(2, +oo)Step-by-step explanation:
Solving in steps
2x - 3 > 11 - 5x2x - 3 + 5x + 3 > 11 - 5x + 5x + 37x > 147x/7 > 14/7x > 2x = (2, +oo)If a person walks 1/3 mile in 15 minutes, how far will that person walk in 1 hour
The distance the person would walk in one hour given the distance walked in 15 minutes is 1/45 miles.
What is the distance walked in one hour?Division is the process of dividing a number into equal parts using another number. The sign used to denote division is ÷.
the distance walked in one hour = 1/3 ÷ 15
1/3 x 1/ 15 = 1/45 miles

Five brothers wanted to share a parcel of land inherited for their late father. The first born received ¼ of the parcel. The second, third and fourth born each received 1/6 of the remainder. If the portion received by the last born was 3 hectares, what was the initial size of the parcel land?
Step-by-step explanation:
Let the size of their father's land be x.
The first born received x/4
The second, third and fourth born each received 1/6 * (x - x/4) = 3x/24 = x/8
The portion received by the last born = x - (x/4 + 3*x/8) = x - (x/4 + 3x/8) = x - (5x/8) = 3x/8
3x/8 = 3hectares
3x = 24
x = 8.
. : The initial size of the parcel land was 8 hectares.
Which of these place values is found to the left of 0.001? a) ones b) tenths
Match each phrase to its correct translation as an algebraic expression. Please help me out, I'm struggling LOL.
Answer:
A number plus two and three-tenths. → x + 2.3
A number divided by three-tenths. → x / .3
Four, subtracted from three times a number. → 3x - 4
Four, added to twice a number. → 2x + 4

Does it equal 2? True or
False.
Add in order from left to right:
-9 + 5 = -4
-4 -10 = -14
-14 + 3 = -11
False, it does not equal 2.
Answer:
False. It equals -11.
Step-by-step explanation:
Simply because if you add -10+3, you get -7. Then if you add -9 and 5, you get -4. when you add -4 and -7 together, you get -11.
Louise used this figure to model the expression 20 divided by 4.
A number line going from 0 to 20. An arrow goes from 4 to 8, from 8 to 12, from 12 to 16, and from 16 to 20.
What error did Louise make in her model?
The small arrows are pointed in the wrong direction.
The small arrows should all end in the same place as the large one.
The arrows should start at zero.
There should be one large arrow and 20 small arrows.
Answer:
The answer is , The arrows should start at zero .

IDK WHY ITS SPREAD APART
Answer:
I answered #1 on a previous question
2) A
Step-by-step explanation:
2) So the formula for consecutive integers is x+x+1+x+2 and so on.
So we know there are 6 integers so the final would be x+5.
so the sum of the final and the first is x+5+x=1
Simplify the equation and solve
2x+5=1
2x=-4
Divide 2 on both sides
x=-2
so -2 is the least Interger of all.
Check: Use the equation x+5 since it’s the greatest, so since x is -2 subsitute and you’ll get -2+5 you'll get 3 and 3+-2=1

Solve the system by substitution
Answer:
(x, y, z) = (-3, 2, 5)
Step-by-step explanation:
Using the first equation, we can write an expression for x:
x = 21 +3y -6z
Substituting this into the remaining two equations gives ...
3(21 +3y -6z) +2y -5z = -30
63 +9y -18z +2y -5z = -30
11y -23z = -93
and
2(21 +3y -6z) -5y +2z = -6
42 +6y -12z -5y +2z = -6
y -10z = -48
This second equation makes it easy to write an expression for y:
y = 10z -48
Substituting that into the previous equation, we have ...
11(10z -48) -23z = -93
110z -528 -23z = -93
87z = 435
z = 5
y = 10(5) -48 = 2
x = 21 +3(2) -6(5) = -3
The solution is (x, y, z) = (-3, 2, 5).

A company earns $6.00 for
every t-shirt they sell. The
same company spends $400 in
advertising each month.
If they profit $800 at the end
of the month, how many t-
shirts did the company sell?
Write an equation to determine how many t-shirts the company sold?
HELP PLEASE
Answer:
Either 133 or 134 T-shirts
Step-by-step explanation:
If you divide the profits at the end of the month by $ per T-shirt, you get approximately 133.333 T-shirts, which rounds to 133-134 T-shirts. Basically the margin of error for this answer is 1.
Answer:
400x800=x solve for x , X =320000
X÷ 6 = 53333.3333333

One of the exterior angles of a triangle is 120° and the
interior,opposite angles are in the ratio 4:2. Find the
anglés of the triangle
Answer:
the angles are 80 degrees and 40 degrees
Step-by-step explanation:
The sum of two opposite interior angles equal to the exterior opposite angle.
so;
4x + 2x = 120
x = 120 / 6
x = 20
4x = 80
2x = 40

Let y = ax²+bx+c then substitute all of orders. we'll be doing equations system.
[tex]a-b+c=0\\c=3\\a+b+c=2[/tex]
Ok we are at this.
Substitute c = 3 into equation 1 and equation 3.
[tex]a-b+3=0\\a-b=-3[/tex]
[tex]a+b+3=2\\a+b=2-3\\a+b=-1[/tex]
then addition and subtract for a-b = 3 and a+b = -1
[tex]a-b=-3\\a+b=-1\\2a=-4\\a=-2[/tex]
Therefore a = -2, substitute a = -2 in a-b+c=0 or a+b+c=2 but i'm doing a-b+c=0 one.
[tex]a-b+c=0\\\\-2-b+3=0\\-b+1=0\\-b=-1\\b=1[/tex]
Therefore b = 1, substitute both a, b and c into y=ax²+bx+c as we get,
