5 people visited SmashBurger. Each person bought a hamburger (h) and a bottle of water (w). Write an expression that shows the amount of hamburgers and bottles of water were purchased.
Answer: 5(h + w)
Step-by-step explanation:
Number of visitors = 5
Each of the five visitors purchased:
One hamburger (h) + one bottle water (w)
Expression for the amount of harmburger and bottle water purchased is thus ;
Number of visitors × (number of harmburger per person + Number of bottle water per person)
5 ( 1h + 1w)
5h + 5w = 5(h + w)

810-162=648
-8x -3(2x+1)=67 Find the value of X
Answer:
x=-5
Step-by-step explanation:
-8x-6x-3=67
-14x=70
x=-5
Answer:
x = -5
Step-by-step explanation:
Solve for x:
-8 x - 3 (2 x + 1) = 67
-3 (2 x + 1) = -6 x - 3:
-6 x - 3 - 8 x = 67
Grouping like terms, -6 x - 8 x - 3 = (-8 x - 6 x) - 3:
(-8 x - 6 x) - 3 = 67
-8 x - 6 x = -14 x:
-14 x - 3 = 67
Add 3 to both sides:
(3 - 3) - 14 x = 3 + 67
3 - 3 = 0:
-14 x = 67 + 3
67 + 3 = 70:
-14 x = 70
Divide both sides of -14 x = 70 by -14:
(-14 x)/(-14) = 70/(-14)
(-14)/(-14) = 1:
x = 70/(-14)
The gcd of 70 and -14 is 14, so 70/(-14) = (14×5)/(14 (-1)) = 14/14×5/(-1) = 5/(-1):
x = 5/(-1)
Multiply numerator and denominator of 5/(-1) by -1:

2x+x+3=6x
What does x equal?
Answer: x=1
Step-by-step explanation:
Simplify 2x+x+3 to 3x+3
3x+3=6x
Subtract 3x from both sides.
3=6x-3x
Simplify 6x-3x to 3x
3=3x
Divide both sides by 3.
1=x
Switch both sides
x=1
Answer:
[tex]2 x + x + 3 = 6x : x = 1[/tex]
Step-by-step explanation:
[tex]2x + x + 3 = 6x[/tex]
Add similar elements: [tex]2x + x = 3x[/tex]
[tex]3x + 3 = 6x[/tex]
Subtract 3 from both sides:
[tex]3x + 3 - 3 = 6x - 3[/tex]
Simplify:
[tex]3x = 6x - 3[/tex]
Subtract 6x from both sides:
[tex]3x - 6x = 6x -3 - 6x[/tex]
Simplify:
[tex]-3x = - 3[/tex]
Divide both sides by -3:
[tex]\frac{-3x}{-3} = \frac{-3}{-3}[/tex]
Simplify:
[tex]x = 1[/tex]

In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we divided by 2 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.
[tex]\frac{1}{2} (x - 1) - \frac{1}{6} (x+1) = 0[/tex]
→ Expand the brackets
[tex]\frac{1}{2} x- \frac{1}{2}-\frac{1}{6}x -\frac{1}{6} =0[/tex]
→ Multiply everything by 12 to make solving the equation easier
6x - 6 - 2x - 2 = 0
→ Simplify equation
4x - 8 = 0
→ Add 8 to both sides to isolate 4x
4x = 8
→ Divide by 4 on both sides to isolate x
x = 2
⇒ We can substitute x = 2 back into the equation to see if the solution is correct, if we get 0 on both sides then x = 2 is correct
[tex]\frac{1}{2} (x - 1) - \frac{1}{6} (x+1) = 0[/tex]
⇒ Substitute in the values
[tex]\frac{1}{2} (2-1)-\frac{1}{6} (2+1) = 0[/tex]
⇒ Simplify
[tex]\frac{1}{2} (1)-\frac{1}{6} (3) = 0[/tex]
⇒ Simplify further
[tex]\frac{1}{2} -\frac{1}{2} =0[/tex]
0 = 0
The solution x = 2 is correct

The interior angles of a triangle have measures kº, 27°, and 10°
What is the value of k?
Answer:
k = 143

The sum of the 3 interior angles of a triangle = 180°, thus
k = 180 - (27 + 10) = 180 - 37 = 143
X/5+2 = -1
Solve 2-step equations
Answer:
X = -15
Step-by-step explanation:
X/5+2 = -1

X/5 *5 = -3*5
X = -15
Answer:
x =-15

at a fourth of july celebration, a rocket is launched straight up with an initial velocity of 128 ft. The height of the rocket in feet above sea level is modeled by the expression 128t - 16t^2, where T is the time in seconds after the rocket is launched. (a) what is the gcf of each term of the expression? (b) write the factored form of the expression for the height of the rocket after T seconds. (c) well the height of the rocket be greater after four seconds or after six seconds?
Answer:
Step-by-step explanation:
Given
Height of the rocket is given by
[tex]h=128t-16t^2[/tex]
[tex]h=8\times 16t-16t\times t[/tex]
(a)Greatest common factor in each term is [tex]16t[/tex]
(b)
[tex]h=8\times 16t-16t\times t[/tex]
[tex]h=16t(8-t)[/tex]
(c)
After [tex]t=4\ s[/tex]
[tex]h=16\times 4(8-4)[/tex]
[tex]h=256\ m[/tex]
after [tex]t=6\ s[/tex]
[tex]h=16\times 6(8-6)[/tex]
[tex]h=192\ m[/tex]
Thus after [tex]4\ s[/tex] height of rocket is greater .

A number is greater than 8. The same number is less than 10. The inequalities > 8 and x < 10 represent the situation, which
best explains the number of possible solutions to the inequality?
There is one solution because 9 is the only number between 8 and 10,
There are a three solutions because 8. 9, and 10 are possible seyitions
There are a few solutions because there are some tractions and decimals between 8 and 10,
There are infinite solutions because there is always another number between any two numbers,
Answer:
There are infinite solutions because there is always another number between any two numbers,
Step-by-step explanation:
This is because in the given equation >8 and x < 10 we are not told of the unique numbers we are searching for be it a decimal or a larger number searching for a unit of 9. ie) 8.0009 or searching for specific 9's.

Suppose you deposit $100 in Account A with a simple interest rate of 3.4%, and $300 in Account B with a simple interest rate of 1.8%. One year later, you get a bank statement, that shows the interest for Account A is $3.40 and the interest for Account B is $540.00. Which account is incorrect?
Answer:Statement for Account B is incorrect.
Step-by-step explanation:
Interest for Account B should be 300 x 1.8% = $5.40
The account B is incorrect. The interest of account B is $5.40.
What is simple interest?The crediting of cash flows associated with an investment or deposit is referred to as "simple" interest.
In finance and economics, interest is the payment of an amount above the repayment of the principal sum by a borrower or deposit-taking financial institution to a lender or depositor at a specific rate by a borrower or depositor.
