Answer:
9
Step-by-step explanation:
2(x-11) + 5-1
We can use the distributive property:
2x - 22 + 5 - 1
We can then simplify:
2x - 18
In this case, if 2x - 18 = 0, then 2x = 18 and x = 9.
Answer:
2x-18
Step-by-step explanation:
[tex]2(x-11)+5-1\\[/tex]
Expand
[tex]2\left(x-11\right):\quad 2x-22[/tex]
Slot it into the equation
[tex]=2x-22+5-1[/tex]
Add/subtract the numbers
[tex]-22+5-1=-18\\\\=2x-18[/tex]

3 - 4x = 6x + 93
Please help with this question
Answer:
-9
Step-by-step explanation:
X=-9
Step-by-step
Simplifying
3 + -4x = 6x + 93
Reorder the terms:
3 + -4x = 93 + 6x
Solving
3 + -4x = 93 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
3 + -4x + -6x = 93 + 6x + -6x
Combine like terms: -4x + -6x = -10x
3 + -10x = 93 + 6x + -6x
Combine like terms: 6x + -6x = 0
3 + -10x = 93 + 0
3 + -10x = 93
Add '-3' to each side of the equation.
3 + -3 + -10x = 93 + -3
Combine like terms: 3 + -3 = 0
0 + -10x = 93 + -3
-10x = 93 + -3
Combine like terms: 93 + -3 = 90
-10x = 90
Divide each side by '-10'.
x = -9
Simplifying
x = -9
1. Five gallons of lemonade cost $8.00, which is
a rate of _____per____.
Answer:
1. $1.60
2. gallon
Step-by-step explanation:
Each gallon of lemonade would cost $1.60.
The rate is $1.60 per gallon.
Hope it helps!
Hey there!
[tex]Answer: \boxed{1.60 \text{ per } gallon}[/tex]
[tex]Explanation:[/tex]
If 5 gallons cost 8.00, we will need to divide to find the amount of 1 gallon each.
$[tex]$8.00/5=1.60[/tex]
So that means that each gallon was $1.60. So the answer to your question is:
[tex]\boxed{1.60 \text{ per } gallon}[/tex]

what is coefficient of the term 16x
Answer:
16
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
We are given the term:
16x
We want to find the coefficient.
A coefficient is a constant that a variable is multiplied by. Essentially, it is the number in front of the variable.
The variable in the term is x. The number that precedes the variable is 16. Therefore, the coefficient of the term must be 16.

Cassandra rents a bicycle while on vacation.
The table below shows the cost of renting a bicycle y, per hour, x.
What is the slope (m) that is defined by the table?
Explain using 2-3 sentences or show each step.
Answer:
m = 6
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply choose 2 points and plug them into the formula to find slope m:
(1, 20)
(2, 26)
[tex]m=\frac{26-20}{2-1}[/tex]
[tex]m=\frac{6}{1}[/tex]
m = 6

17 less than h equals 42
Answer:
17 < h = 42
Step-by-step explanation:
Hoped this helped! :)
we cannot have a negative number for x (its against the laws of math), so the domain would be all non-negative numbers
Answer:
h - 17 = 42

Adam and Barb planned a used book sale for the weekend so they gathered their books and agreed on a price for hardbacks and a lower price for paperbacks. Adam sold 14 hardcover books and 20 paperbacks and earned $234 for his efforts. Barb sold 15 hardcover books and 9 paperbacks. Barb made $201. How much did they charge for each hardcover book and for each paperback?
You must show your work.
1) Mathematically what kind of problem is this called? (What concept did you apply to this problem that allowed you to solve it?)
2) Set up the problem showing the equations you’ll use. Please make sure you label or explain what your variables mean.
3) Show the math work to arrive at the answer. Please make it clear which price is hardcover and which is paperback.
Answer: hardcover books x=11 and paperbacks y=4
Step-by-step explanation:
14x+20y=234
15x+9y=201
Multiply the top equation by 9 and the bottom equation by 20 so the outcome of both equations would be 126x+180y=2106 and 300x+180y=4020 then you subtract the two equations once you do that you get 174x=1914, and the y variable cancels out, once you divide 174 from 1914 you get 11x. So the answer for how much hardcover books cost is 11 dollars. Now we have to find the y variable which we can just plug in 11 (x) into the equation. So 15(11)+9y=201 we get 165+9y=201, subtract 165 from both sides and we get 9y=36 and divide 9 from both sides and we get 4 so y=4 the cost of paperbacks are 4 dollars

Lupe put $12,000 in a certificate of deposit that gained interest at a rate of 6.5%. How much interest did the account gain after 3 months?
Answer:
$195
Step-by-step explanation:
We use the simple interest formula.
I = Prt
I = Interest
P = Principal (initial value)
r = Interest rate
t = Time (years)
P = $12,000
r = 6.5% which we convert to a decimal by dividing by 100 6.5/100 = .065
t = 3 months which we convert to years by dividing by 12 3/12 = 1/4 = .25
Plug in the values
I = 12000 * .065 * .25
I = $195 interest gained
Answer:
195
Step-by-step explanation:
3 month is .25 years
6.5/100 = .065
12000 x .065 x .25 = 195
(8w)^2 without parentheses
Answer:
I believe the answer would be 64w2.
Step-by-step explanation:
8 squared is 8 x 8, which equals 64, and then w squared is just w2, since we don't know what it is. Put them together, and the answer is 64w2.

Answer:
a = h/5
Step-by-step explanation:
If you had the equation ...
10 = 5a
and you wanted to find the value of the variable, you would divide by its coefficient:
10/5 = (5a)/5
2 = a
__
Here, we have replaced '10' with 'h'. The same (single) step applies: divide by the coefficient of 'a'.
h = 5a
h/5 = a
To put this in "a = " form, swap the sides of the equal sign:
a = h/5
_____
Literal equations just use different symbols (h instead of 10, here). The operations are the same.

What is an exact solution for
[tex]m \sqrt{14} [/tex]
Answer: Choice B) [tex]\sqrt{14}[/tex]
We have some value m and we're squaring it to get [tex]m^2[/tex]
To undo this and isolate m, we apply the square root to both sides
[tex]m^2 = 14\\\\\sqrt{m^2} = \sqrt{14}\\\\|m| = \sqrt{14}\\\\m = \sqrt{14} \text{ or } m = -\sqrt{14}[/tex]
There are two solutions here. This is similar to how there are two solutions in something like [tex]x^2 = 25[/tex] (those two solutions being x = 5 and x = -5). Squaring any negative number leads to a positive result because
negative times negative = positive.
