Solve 2( 4x - 1) = 18
Answer:
x=2Step-by-step explanation:
Simplifying
2(4x + 1) = 18
Reorder the terms:
2(1 + 4x) = 18
(1 * 2 + 4x * 2) = 18
(2 + 8x) = 18
Solving
2 + 8x = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2' to each side of the equation.
2 + -2 + 8x = 18 + -2
Combine like terms: 2 + -2 = 0
0 + 8x = 18 + -2
8x = 18 + -2
Combine like terms: 18 + -2 = 16
8x = 16
Divide each side by '8'.
x = 2
Simplifying
x = 2

I need to step-by- step ways on how this is or isn’t a solvable equation. Please HELP
Answer:
it is a solvable equation
Step-by-step explanation:
(x + 2) -3(x - 4) = 6 and x = 4
if x = 4 then fill in all the x's with 4 so the equation is now:
(4 + 2) -3(4 - 4) = 6
Use PEMDAS
Now the equation is 6 - 3(0) = 6
-3 times 0 is 0 so it's 6-0=6
6 = 6
when you put the 4 in for the x variables and the numbers on both sides of the equal sign are the same it makes the equation true
hope this makes sense and hope it helps :)

Roy and two friends are at a game center. Each person buys hot dogs for $3, fries for $2.49, and a drink for $2.50. They also have a coupon for $1 off each drink. Write an expression to represent the total cost. Then find the total cost.
Answer:
$20.97
Step-by-step explanation:
3 people, meaning to multiply each one by 3.
Total price of Hot Dogs= 9.00
Total price of Fries=7.47
Total price of Drinks=7.50
7.50 - 3= $4.50
9.00+7.47+4.50= $20.97

Connor is going to see a movie and is taking his 4 kids. Each movie ticket costs $13 and there are an assortment of snacks available to purchase for $5 each. How much total money would Connor have to pay for his family if he were to buy 5 snacks for everybody to share? How much would Connor have to pay if he bought xx snacks for everybody to share?
If Connor buys 3 snacks at 3 dollars each for himself and his 3 children, the net cost (including movie tickets) would be 88 dollars.
If he buys x amount of snacks, his cost will be determined by C=52+3x or C=52+3*x (both are equivalent, but not everyone knows every way to represent multiplication)
Step-by-step explanation:
To find the cost of the snacks:
Cost = Price*NumberOfSnacks, or C=p*n, or C=pn
To find the unit cost of the snack, find the price, the p value, which is 3 dollars.
Then, find the total number of snacks that will be bought. Since each person receives an equal number of snacks, 3 per person, and there are 4 people (himself and his 3 children), we can multiply 3*4 to find the n value, which is now known to be 12.
C=3*12=36. Add to the 13 dollar per person charge for tickets (52 dollars for 4 people), and you get 88 dollars.
To find the cost if he buys x amount of snacks for himself and his 3 children (assumed to be "everyone"), all costs but the n value are to be the same, creating this equation:
C=52+3x
In this context, 52 is the cost of movie tickets, 3 is the cost of the snacks, and x is the total number of snacks bought. C represents total cost.
The total cost for tickets and 5 snacks is $90.
The total cost for tickets and x snacks is $(65+5x).
Total cost:Important information:
Number of kids = 4Cost of each ticket = $13Cost of each snacks = $5Number of snacks = xThe total number of people is 5. So, cost of 5 tickets is:
[tex]5\times 13=65[/tex]
Cost of 5 snacks is:
[tex]5\times 5=25[/tex]
Total cost is:
[tex]65+25=90[/tex]
The total cost for tickets and 5 snacks is $90.
Cost of x snacks is:
[tex]5\times x=5x[/tex]
Total cost is:
[tex]65+5x[/tex]
The total cost for tickets and x snacks is $(65+5x).

Answer:
D
Step-by-step explanation:
All real numbers are solution
Step 1: Simplify both sides of the inequality.
8x−7<8x−3
Step 2: Subtract 8x from both sides.
8x−7−8x<8x−3−8x

simplify the expression -6 - 7 (c+10)
Answer:
[tex]-6-7\left(c+10\right)=-7c-76[/tex]
Step-by-step explanation:
Given the expression
[tex]-6\:-\:7\:\left(c+10\right)[/tex]
simplifying the expression
[tex]-6-7\left(c+10\right)[/tex]
Expanding -7(c + 10) = -7c - 70
[tex]-6\:-\:7\:\left(c+10\right)=-6-7c-70[/tex]
subtract the numbers: -6 - 70 = -76
[tex]=-7c-76[/tex]
Therefore, we conclude that:
[tex]-6-7\left(c+10\right)=-7c-76[/tex]

Last week at the park, Heather ran 4 miles in 48 minutes. When she runs her next race, she hopes to improve her time by 2 minutes per mile.
Last week at the park, what was Heather’s rate of speed in miles per hour? Use words and/or numbers to explain your answer.
Answer:
she ran 10 miles a hour
Step-by-step explanation:
she runs 10 miles a hour because she wants to improve her time per mile by 2 minutes so you do 2x4 and get 8, then you subtract 8 from 48 and get 40 then you divide 40 by 4 and get 10
Heather's rate of speed last week was 1/12 miles/min.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that last week at the park, Heather ran 4 miles in 48 minutes. When she runs her next race, she hopes to improve her time by 2 minutes per mile.
Heather's rate of speed last week -
{r} = 4/48 = 1/12 miles/min
{r} = 1/12 miles/min
Therefore, Heather's rate of speed last week was 1/12 miles/min.
