Answer:
x = 4
Step-by-step explanation
2x−5+x=−x+7+x
3x−5=7
3x−5+5=7+5
3x=12
x=4
Answer:
x = 4
Step-by-step explanation:
You need to isolate the variable on one side first so that the equation is easier to solve. To do that, add x to both sides to get 2x + x, which is 3x. This gets rid of the -x on the other side and results with the new equation
3x - 5 = 7. Add 5 to both sides to get 3x = 12, then divide both sides by 3 to get x = 4.
You can check your work by plugging in 4 for x.
2(4) - 5 = -(4) + 7
8 - 5 = 3
3 = 3
Therefore, x is equal to 4.
Hope this helped! Have a good day!
Solve the inequality for w.
7w > 35
Answer:
w≥5
Step-by-step explanation:
You just divide 7 by both sides which cancels it on the left, and you get 5 on the other side because 35 divided by 7 is 5.

The final enrollment for the spring 2012 semester at The Florida State University
Panama City was confirmed to be 1,342 students. The year before it was 1,550 students. What was the
percent change in student enrollment?
Answer:
13% decrease. (13.4193548...% to be specific)
Step-by-step explanation:
The difference is 1550-1342=208. 208 as a percentage of 1550 --> 208/1550= 0.134193548... = 13% to the nearest whole number. So, it is a 13% decrease.

Given:
LMN is an equilateral triangle.
LM = LN = MN = 12 cm
To find:
The height of the triangle h.
Solution:
In a right angle triangle,
[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]
[tex]\sin (60^\circ)=\dfrac{h}{12}[/tex]
[tex]\dfrac{\sqrt{3}}{2}=\dfrac{h}{12}[/tex]
Multiply both sides by 12.
[tex]\dfrac{\sqrt{3}}{2}\times 12=\dfrac{h}{12}\times 12[/tex]
[tex]6\sqrt{3}=h[/tex]
Therefore, the height of the triangle is [tex]6\sqrt{3}[/tex] cm.

find the slope of the line that passes through (6, 3) and (10, 6)
Step-by-step explanation:
3/4
insert 1st point into y=mx+b
3=m(6)+b
insert 2nd point into y=mx+b
6=m(10)+b
-----------------------------------
use system of equations to solve for m and b
b=3-6m
b=6-10m
3-6m=6-10m
4m=3
m=3/4
insert back into the equation
3=(3/4)6+b
3=9/2+b
3-9/2=b
-3/2=b
insert back into y=mx+b
m=slope
b=y-intercept
y=(3/4)x-3/2
slope=3/4

Malik can spend no more that $24 to buy pecans and cashews. He will spend $6 per
pound for pecans and $8 per pound for cashews. Which graph represents the number
of pounds of pecans and the number of pounds of cashews Malik can buy?
Answer:
Graph D
Step-by-step explanation:
We can look at the number of pounds of pecans and cashews, shown on the x- and y-axis, respectively.
All of the graphs have an x-intercept of (4, 0), meaning that the number of pecans being bought is 4 lbs.
Since pecans cost $6 per lb, we can multiply the cost by 4 in order to make sure that the total cost is not exceeding $24.
$6 · 4 lbs = $24Let's look at the y-axis to see how many lbs of cashews Malik can buy. The y-intercept is (0, 3) for all graphs, meaning that 3 lbs of cashews are being bought.
Since cashews cost $8 per pound, we can multiply the cost by 4 in order to make sure that the total cost is not exceeding $24.
$8 · 3 lbs = $24The shaded area represents the values that can be used in the problem. Since we want $24 or less, the shaded region has to be below the line.
Malik can spend no more than $24, so the line should be solid since this means that the values the line touches are inclusive. 4 lbs of pecans and 3 lbs of cashews should be inclusive.
The graph that has all of these properties is Graph D.

n
Answer:
(n-7) ≤ 95
Step-by-step explanation:
We need to write the expression for the given statement.
Seven less than the product of a number n and 1 means (n-7).
It is no more than 95. No more than 95 means less than or equal to i.e.
(n-7) ≤ 95

A cone has a diameter of 12 centimeters and a height of 9 centimeters. Using 3.14 for pi, find the
volume of the cone to the nearest tenth.
A cone has a diameter of 12 centimeters and a height of 9 centimeters. The volume of the cone would be 2034.72 cubic cm.
How to find the volume of a right circular cone?
Suppose that the radius of considered right circular cone be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \dfrac{1}{3} \pi r^3 h \: \rm unit^3[/tex]
The right circular cone is the cone in which the line joining the peak of the cone to the center of the base of the circle is perpendicular to the surface of its base.
A cone has a diameter of 12 centimeters and a height of 9 centimeters.
Radius = 12/2 = 6cm
Height h = 9 cm
The volume of the cone
[tex]V = \dfrac{1}{3} \pi r^3 h \: \rm unit^3[/tex]
[tex]V = \dfrac{1}{3} \times 3.14 \times 6^3 \times 9\: \rm unit^3\\\\V = 3.14 \times 648\\\\V = 2034.72 cm^{3}[/tex]
Hence, The volume of the cone would be 2034.72 cubic cm.
