Answer:
-3
Step-by-step explanation:
6x take 4x equals 2x
So it'll be 2x+4=-2
Then you do - 2 take 4 which is - 6
So then it is 2x=-6
-6÷2=-3
Hope this helps you :)
Answer:
x=-3
Step-by-step explanation:
6x+4=4x-2
Subract the x on the right side on both sides
Equation should now be:
2x+4=-2
Now subtract the 4 from both sides
The equation is now:
2x=-6
Now all you have to do is divide the x on both sides
Your answer is now x=-3
Solve the following equation 4x+4 = -3+2x+15
x = 4
Step-by-step explanation:4x + 4 = -3 + 2x + 15
4x - 2x = 15 - 3 - 4
2x = 8
x = 8 : 2
x = 4
2-3x-5+9x=? Thank you to whoever gets the answer
Answer:
6x - 3
Step-by-step explanation:
Step 1: Write out expression
2 - 3x - 5 + 9x
Step 2: Combine like terms (x)
2 - 5 + 6x
Step 3: Combine like terms (constants)
-3 + 6x
Step 4: Rewrite
6x - 3
A camping ground began with 240 pounds of food and each day consumed about 12 pounds. After how many days did they have 180 pounds left
Answer:
5 days
Step-by-step explanation:
Set up linear equation; food= 240-12(day) f=240-12d
f(1)=240-12(1)=240-12=228
f(2)=240-12(2)=240-24=216
Now set food to equal 180, solve for days:
180=240-12d
-240 -240
-60=-12d
/-12 /-12
5=d
To check: f(5)=240-12(5)=240-60=180

Violet was carrying around the steps to solve square root of 3x plus 1 = 4. On her way through the Math Factory, Violet dropped them and they mixed with other steps. Put the correct steps in order to solve square root of 3x plus 1 = 4.
Answer:
First, square both sides (d.) leaving 3x + 1 = 16
Second, subtract 1 from both sides (a.) leaving 3x = 15
Third, divide by 3 from both sides (e.) leaving x = 5
Answer: First D, then A, then E

Mr. Drew wants to build a square sandbox for his children. The area of the sandbox will be 104 ft2. To the nearest tenth, what is the total length of Mr. Drew wants to build a square sandbox for his children. The area of the sandbox will be 104 ft2. To the nearest tenth, what is the total length of wood Mr.drew needs to make the sides of the sandbox
Answer:
26 ft.2
Step-by-step explanation
Divide 104 by 4 because the sandbox is a square. With a square all sides are equal length, so you just divide by the amount of sides.

evaluate the expression. 5^2. what is the value of the expression?
Answer:
25
Step-by-step explanation:
Any numbers to the 2nd powered are always squared. Whenever you are given an exponent, the base is the number that you multiply, and the power is one more than how many times you multiply the base number together. In this case, you multiply five by itself once to get 25 as your answer.

Using technology or other resources, research the average distance that each planet is from the Sun
(in kilometers). Once you have found the distance, create a chart showing each planet's distance
from the Sun. The Sun itself will not receive a label since it is your starting point. For example,
Mercury is located an average of 57,909,000 km from the Sun, so on the chart, Mercury would be
labeled with a distance of 57,909,000. Use the chart below to record your answers:(Add rows if
necessary)

the ratio of picnic tables to garbage cans in a new national park should be 5:2. the park design shows plans for 30 picnic tables in a small campground and 110 picnic tables in a large camp ground how many garbage cans should there be in each campground
Answer:
Small campground = 12 garbage cans
Large campground = 44 garbage cans
Step-by-step explanation:
Picnic tables : garbage cans
= 5 : 2
Small campground = Picnic tables : garbage cans
= 30 : x
5 : 2 = 30 : x
5/2 = 30/x
Cross product
5 * x = 2 * 30
5x = 60
x = 60/5
= 12
5 : 2 = 30 : 12
large camp ground = Picnic tables : garbage cans
5 : 2 = 110 : x
5/2 = 110/x
Cross product
5 * x = 2 * 110
5x = 220
x = 220/5
= 44
5 : 2 = 110 : 44
Therefore, there are 12 garage cans in the small campground and 44 garbage cans in the large campground

Express 18.348 in the form p/q where p and q are integers, q≠ 0
Answer:
[tex]\frac{18348}{1000}[/tex]
Step-by-step explanation:
The 8 in the decimal part 0.348 is in the thousandths position, thus
18.348
= 18 [tex]\frac{348}{1000}[/tex]
= [tex]\frac{18(1000)+348}{1000}[/tex]
= [tex]\frac{18348}{1000}[/tex]
Mario has LaTeX: 2\frac{1}{4}2 1 4 pounds of trail mix. He puts equal amounts of the trail mix into 6 bags for a hike with his friends. If he uses all of the trail mix, how many pounds will be in each bag?
Answer:
0.375 poundsStep-by-step explanation:
Let the amount of trail mix in each bag be x pounds. If Mario has [tex]2\frac{1}{4}[/tex] pounds of trail mix and puts equal amounts of the trail mix into 6 bags for a hike with his friends, the amount of trail mix in each bag can be derives using the expression;
[tex]2\frac{1}{4} = 6 * x[/tex]
solving for x
[tex]\dfrac{9}{4} = 6x\\\\2.25 = 6x\\\\divide\ both \ sides \ by \ 6\\\\\dfrac{2.25}{6} = \dfrac{6x}{6} \\\\x = 0.375\\[/tex]
Hence 0.375 pounds of trail mix will be in each bag
the sum of a number x and 10
Answer:
x + 10
Step-by-step explanation:
x and 10 are not the same
The sum of the numbers x and 10 is ( x + 10 ).
What is summation?The process of increment of any number of quantities or the process of integrating small parts to make a big part is called summation.
The given numbers are x and 10. The sum of the given numbers x and 10 is calculated as:-
Sum = x + 10
Hence, the sum is ( x + 10 ).

4 square root of 18 simplified
Answer:
[tex]\sqrt{288}[/tex]
Step-by-step explanation:
What we have here is a radical: [tex]4\sqrt{18}[/tex].
Radicals can be made by dividing a number into a perfect square and a number, then taking the square root of the perfect square and putting it outside the square root symbol.
This means that the number here will be [tex]18\cdot(4^2)[/tex]
[tex]4^2 = 16\\\\16\cdot18=288[/tex]
