Answer:
x=10
Step-by-step explanation:
Simplifying
1.5x + 3 = 18
Reorder the terms:
3 + 1.5x = 18
Solving
3 + 1.5x = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 1.5x = 18 + -3
Combine like terms: 3 + -3 = 0
0 + 1.5x = 18 + -3
1.5x = 18 + -3
Combine like terms: 18 + -3 = 15
1.5x = 15
Divide each side by '1.5'.
x = 10
Simplifying
x = 10

What is the mass of 2.5 moles of carbon dioxide?
Answer:
110 grams
Step-by-step explanation:
CO2 molecule is made up of Carbon (atomic mass =12) and oxygen (atomic mass=16).
So first finding the mass of 1 molecule of CO2 which is equals to
= mass of 1 carbon atom + masses of 2 oxygen atom, we get
= 12+(16*2)= 12+32= 44 a.m.u.
Now 1 molecule of CO2 has mass 44 amu so mass of 1 mole CO2 will be 44 grams.( 1 a.m.u.=1.6729*10^-33 grams. 1 mole = 6.022*10^23, so 44 a.m.u.=73.6076*10^-33 grams approx. For one mole CO2, 73.6076*10^-33*6.022*10^23 which is approximately equals to 44 grams. )
1 mole CO2= 44grams, so 2.5 moles = 44*2.5= 110 grams
So our answer is 110 grams.
lowkey hope this helped you, good luck whatever you need it for Imaooo
How much solutions does this equation have?
2x+y=3
2y=-4x+6
pls answer,, show ur work, have a great day :)) !!
Answer:
All solutions or infinite.
Step-by-step explanation:
Turn 2y = -4x + 6 into standard form - divide by 2
Y = -2x + 3
2x + y = 3
Substitute the y equation in for y.
2x - 2x + 3 = 3
The x variables cancel out.
3 = 3
Which is true so it means all solutions.
Hope this helps.

gonzalo nacio el 18 de sptiembre de 1945 si bertha nacio cuatro decadas y un lustro cual es la fecha de nacimiento de bertha
Answer: Bertha nació el 18 de septiembre de 1990.
Step-by-step explanation:
Gonzalo nació el 18 de septiembre de 1945.
Bertha nació cuatro décadas y un lustro después.
Una década son 10 años
Un lustro son 5 años
Entonces 4 décadas y un lustro son:
4*10 años + 5 años = 45 años
Esto significa que Bertha nació 45 años después que Gonzalo.
Entonces si Gonzalo nació en 1945, Bertha nació en el año:
1945 + 45 = 1990
Bertha nació el 18 de septiembre de 1990.
La fecha de nacimiento de Bertha es el 18 de septiembre de 1990.
How many years does a decade have?A decade is composed of 10 years. So, if there are 'x' decades, then that means there are going to be [tex]10 \times x[/tex] years in it.
For this case, we are given that:
Date of birth of Gonzelo is 18th of Sept. 1945
Bertha born after 4 decades and 5 years of Gonzelo's birth.
4 decades = 4 times 10 = 40 years
Thus, 4 decades + 5 years = 40 + 5 = 45 years.
45 years after 1945 uis 1945 + 45 = 1990
Thus, date of birth of Bertha is 18th Sept. 1990

Answers:
Sam's current age = 24The mother's current age = 48=========================================================
Explanation:
s = Sam's age right now
2s = the mother's age right now, since she is twice as old as Sam currently.
In 12 years time, Sam will be s+12 years old.
12 years ago from this current year, the mother was 2s-12 years old.
Since we're told these future and past ages line up, this means s+12 and 2s-12 are the same value
Set the expressions equal to one another and solve for s.
s+12 = 2s-12
s-2s = -12-12
-s = -24
s = 24
Sam is currently 24 years old.
His mother is currently 2s = 2*24 = 48 years old.
12 years ago, his mother was 2s-12 = 48-12 = 36 years old.
12 years from now, Sam will be s+12 = 24+12 = 36 years old.
Since we get 36 each time, this confirms we have the correct answers.

6. Solve for x in each of the following equations:
a. m(x + n) =n
b. x( a + b) = b(c - x)
c. mx = n(m + x)
Step-by-step explanation:
m(x + n) = n
mx + mn = n
mx = n - mn
x = (n - mn)/m
x(a + b) = b(c - x)
ax + bx = bc - bx
ax + bx + bx = bc
x(a + b + b) = bc
x(a + 2b) = bc
x = bc/(a + 2b)
mx = n(m + x)
mx = mn+ nx
mx - nx = mn
x(m - n) = mn
x = mn/(m-n)
A pair of pants originally cost 25 dollars but costs 45 dollars. what is the percent markup? Please help!
Answer:
The markup formula is as follows: markup = 100 * profit / cost .
Step-by-step explanation:
For example if your cost is $10.00 and you wish to markup that price by 40%, 100% + 40% = 140%. Multiply the $10.00 cost by 140% and get the retail price of $14.00.
How do you calculate a 45 markup?
Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage.

for #2 it's both lines have the same slope
for #3 it's both lines have a different y-intercept
Step-by-step explanation:
#1 explanation: all of them have the y-intercept of -8
ex. y = 3x (- 8) y = 5x (-8) y = 2x (-8) y = (1/3)x (-8)
#2 explanation: both have a slope of (1/4)
#3 explanation: y = (1/4)x there is not y-intercept that we know of and y = (1/4)x - 5 the y-intercept is at -5 therefore the y-intercepts are different
