To solve the equation, Antwan uses the distributive property, combines like terms, then uses the addition and subtraction properties of equality to isolate the variable term on one side of the equation and the constant term on the other side. What are the possible values of the constant after Antwan has completed these steps?

What is the surface area of a cylinder with base radius 4 and height 5?
Answer:
around 266.188
Step-by-step explanation:
so first find the circumference of the circle, which is 2 x pi x radius
after that, multiply your circumference by the height to find the curved surface area
now find the surface aread of the base and the top, which is just 2 x pi x radius x radius
write an explicit and recursive formula for the sequence -4, -6, -8, 10
Answer:
Each term is 2 greater than the term before it. Thus for any given term, an, our equation is:
an=2n
We can write this in a form closer to standard, by noting that a1=2, so we can make it dependent on a1..
an=a1+2(n−1)=2+2(n−1)

8(5x+ 2) = 296 how to solve this
Answer:
x = 7
Step-by-step explanation:
8(5x + 2) = 296
40x + 16 = 296
40x = 280
x = 7
Answer:
x=7
Step-by-step explanation:
➼Okay, so first thing you need to do is to distribute the 8 to everything in the parentheses:
8(5x+ 2) = 296
8 times 5x
8 times 2
(8 x 5x) + (8 x 2) = 40x + 16
➼Now you solve for x
40x+16=296
➼to get rid of 40 you have to do the opposite and divide it by everything
40x+16=296
40/40=0
16/40=0.4
296/40=7.4
➼all adds up to x + .4 = 7.4 but to get the x alone you need to get rid of the .4, we'll do this by doing the opposite and subtract it from everything
.4-.4=0
7.4-.4=7
➼so in conclusion
x=7

I need answers please
Answer:
Step-by-step explanation:
The equation has to be
8x + 20 = 148 Subtract 20 from both sides
8x = 148 - 20 Combine
8x = 128 Divide by 8
x = 128/8
x = 16

You invested $20,000 in two accounts paying 7% and 8% annual interest, respectively. If the total interest earned for the year was $1530, how much was invested at each rate?
Answer:
$7,000 at 7%; $13,000 at 8%
Step-by-step explanation
x: the amount invested at 7%
y: the amount invested at 8%
x + y = 20,000
7%.x + 8%.y = 1,530
⇒ x =7,000
y = 13,000

[tex]\\ \sf\longmapsto x^2=121+121[/tex]
[tex]\\ \sf\longmapsto x^2=242[/tex]
[tex]\\ \sf\longmapsto x=\sqrt{242}[/tex]
[tex]\\ \sf\longmapsto x=15.4[/tex]
Step-by-step explanation:
Use the pythagorean theorem
[tex]a {}^{2} + b {}^{2} = c {}^{2} [/tex]
[tex]11 {}^{2} + 11 {}^{2} = c {}^{2} [/tex]
[tex]121 + 121 = c {}^{2} [/tex]

4x/x^2-8x+7+5x/x^2-10x+7
Answer:
simplified: -18x + 14 + [tex]\frac{9}{x}[/tex]
Step-by-step explanation:
-8 < 2x - 4 < 8 how do I solve this
-8 < 2x-4 < 8
Add 4 to all sides:
-8 + 4 < 2x -4 + 4 < 8 + 4
Simplify :
-4 < 2x < 12
Divide all sides by 2:
-4/2 < 2x/2 < 12/2
Simplify to get the answer:
-2 < x < 6
what is the answer to -|3x-9|+2=-4
entered :
-|3x-9|+2=-4
Step by step solution :
STEP
1
:
Rearrange this Absolute Value Equation
Absolute value equalitiy entered
-|3x-9|+2 = -4
Another term is moved / added to the right hand side.
To make the absolute value term positive, both sides are multiplied by (-1).
|3x-9| = 6
STEP
2
:
Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |3x-9|
For the Negative case we'll use -(3x-9)
For the Positive case we'll use (3x-9)
STEP
3
:
Solve the Negative Case
-(3x-9) = 6
Multiply
-3x+9 = 6
Rearrange and Add up
-3x = -3
Divide both sides by 3
-x = -1
Multiply both sides by (-1)
x = 1
Which is the solution for the Negative Case
STEP
4
:
Solve the Positive Case
(3x-9) = 6
Rearrange and Add up
3x = 15
Divide both sides by 3
x = 5
Which is the solution for the Positive Case
STEP
5
:
Wrap up the solution
x=1
x=5
I hope this help you
Answer: x= 1, 5
Step-by-step explanation:
First, isolate the absolute value. Subtract two from the equation to get -l3x-9l=-6, and then divide by -1 to get l3x-9l=6.
Since an absolute value measures how far away a value is from zero, it's always positive. For example, -10 and 10 have the same absolute value, 10, because they're both 10 units away from zero.
Because of this, you create two equations; 3x-9=6, and 3x-9=-6.
For the first equation, add 9 to 6 and divide that by 3 to get x=5.
For the second equation, add 9 to -6 and divide that by 5 to get x=1.
