Answer: x=5
Step-by-step explanation:
To solve for x, we want to use algebraic properties to isolate x.
-28+2x=-18 [add both sides by 28]
2x=10 [divide both sides by 2]
x=5
Now, we know that x=5.
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \text{x = 5}}}}}[/tex]
Step-by-step explanation:
[tex] \star{ \sf \: - 28 + 2x = - 18 }[/tex]
[tex] \tt{Step \: 1}[/tex] : Move 28 to right hand side and change it's sign
[tex] \hookrightarrow{ \sf{2x = - 18 + 28}}[/tex]
[tex] \tt{Step \:2}[/tex] : Subtract 18 from 28
The negative and positive integers are always subtracted but posses the sign of the bigger integer
[tex] \hookrightarrow{ \sf{2x = 10}}[/tex]
[tex] \tt{Step \: 3}[/tex] Divide both sides by 2
[tex] \hookrightarrow{ \sf{ \frac{2x}{2} = \frac{10}{2}}} [/tex]
[tex] \tt{Step \: 4}[/tex] Calculate
[tex] \hookrightarrow{ \sf{x = 5}}[/tex]
[tex] \tt{∴ \: The \: value \: of \: x \: is \: \bold{5}}[/tex]

5 (n - 14) =2 (n + 14)
Answer:
n= 98/3
Step-by-step explanation:
1. Complete distributive property *5(n-14)* and *2(n+14)*
5n-70=2n+28
2. Subtract 5n from both sides
-70=-3n+28
3. Subtract -70 from both sides
-98=-3n
4. Divide the variable from both sides *-3n*
-98/-3
5. Simplify
98/3
Final Answer:

What equation can Janet use to calculate the principal amount? (and please don't just answer try to solve it someone ripped me off, the last time i asked by just typing)
Answer:
t = [tex]\frac{l}{pr}[/tex]
Step-by-step explanation:
Formula or literal equation used to calculate the simple interest is,
l = prt
where 'l' = Simple interest
p = principle amount invested
r = rate of interest
t = time or duration of the investment
If we have to calculate the time of investment form the given formula,
l = prt
By the division property of equality,
[tex]\frac{l}{pr}=\frac{prt}{pr}[/tex]
[tex]t=\frac{l}{pr}[/tex]
Therefore, formula to be used is, [tex]t=\frac{l}{pr}[/tex]

Ben’s age, x, is 3 times his age 12 years ago. Finish the equation, using no spaces
Given :
Ben's age x is 3 times his age 12 years ago.
To Find :
The current age of Ben.
Solution :
It is given that current age of Ben is x.
So, his age 12 years ago is (x - 12).
Expressing given condition mathematically , we get :
[tex]x=3(x-12)\\\\x=3x-36\\\\2x=36\\\\x=18\ years[/tex]
Therefore, current age of Ben is 18 years.
Hence, this is the required solution.

what is the answer to -3x+5= -16
Answer: 7
Step-by-step explanation: First you subtract 5 from both sides to single out the -3x. Then you will have -3x = -21. You will then divide both sides by negative three because you want to single out the x. After that, you will have the answer of x = 7
Answer:
x = 7
Step-by-step explanation:
-3x+5=-16
-5 -5
-3x=-21
-3x/3 = -21/-3

Find the measure of angle XAZ in the figure below.
Answer:
m∠XAZ = 40°
Step-by-step explanation:
Since ∠YAU, ∠YAZ and ∠XAZ are the angles based at a point on a straight line, and the sum of the all angles on a line is 180°.
Therefore, m∠YAU + m∠YAZ + m∠XAZ = 180°
50° + 90° + m∠XAZ = 180°
m∠XAZ = 180° - 140°
= 40°
Therefore, measure of angle XAZ is 40°.

Martina drove 792 miles in 11 hours.
At the same rate, how long would it take her to drive 504 miles?
Answer:
7 hours
Step-by-step explanation:
Her rate (speed) is
v = d/t = (792 miles) / (11 hrs) = 72 mph
To drive a distance D = 504 miles, it will take her a time T given by
T = D/v = (504 miles) / (72 mph) = 7 hours

If x represents a number then write an expression for a number that is three more than one third the value of x
Answer:
1/3x+3
It is asking for 1/3 of x which is 1/3x
three more essentially means add 3
So 1/3x+3 is the answer
The expression is,
y = 1/3x+3
Where, y is number write with the help of x
And, x is a number.
Here,
We have to write an expression for a number that is three more than one third the value of x.
What is Number system?
A system of writing to express the number is called Number system.
Now,
x represents a number.
Let a number y which is written as, three more than one third the value of x.
One third of x = 1/3 x
Then, more than 3 means to add 3, we get
y = 1/3 x + 3
Hence, The expression is,
y = 1/3x+3
Where, y is number write with the help of x
And, x is a number.

[tex]3x - 5 = \frac{12 + 4x}{2} [/tex]
x = [?]
Answer:
x= 11
Step-by-step explanation:
[tex]3x - 5 = \frac{12 + 4x}{2} [/tex]
Multiply both sides by 2:
2(3x -5)= 12 +4x
Expand:
2(3x) +2(-5)= 12 +4x
6x -10= 12 +4x
Bring all x terms to 1 side, constant to the other:
6x -4x= 10 +12
2x= 22
Divide by 2 on both sides:
x= 22 ÷2
x= 11
