Answer:
x = 81
Step-by-step explanation:
With this equation, you would first want to multiply -4 to x and -26.
Your new equation is now -4x + 124 = -200
You would then subtract 124 from both sides leaving you with
-4x = -324
Finally, you would divide both sides by -4, leaving you with
x = 81

Which equation describes the line through the points (4,-3) and (5,0)
Answer:
y = 3x - 15
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, - 3) and (x₂, y₂ ) = (5, 0)
m = [tex]\frac{0+3}{5-4}[/tex] = 3 , thus
y = 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (5, 0 ), then
0 = 15 + c ⇒ c = 0 - 15 = - 15
y = 3x - 15 ← equation of line
A prepaid phone card has a balance of $22.40 remaining. If calls are $0.035 per minute, which equation represents the number of minutes, m, you may talk using the card?
Answer:
The equation that represents the number of minutes that Imay talk using the card is [tex]m =28.571\cdot C[/tex].
Step-by-step explanation:
From statement we know that balance ([tex]C[/tex]), measured in US dollars, is directly proportional to remaining call time ([tex]m[/tex]), measured in minutes. That is:
[tex]C \propto m[/tex]
[tex]C = k\cdot m[/tex] (Eq. 1)
Where [tex]k[/tex] is the proportionality ratio, measured in US dollars per minute.
If we know that [tex]k = 0.035\,\frac{USD}{min}[/tex], then the equation is:
[tex]C = 0.035\cdot m[/tex]
Now we clear remaining call time within equation:
[tex]m =28.571\cdot C[/tex]
The equation that represents the number of minutes that Imay talk using the card is [tex]m =28.571\cdot C[/tex].
A recipe uses 4 cups of milk to make 12 servings. If the same amount of milk is used for each serving, how many servings can be made from three gallons? How many cups will you need to find the number of servings for?
Answer:
144 servings
Step-by-step explanation:
1 gallon = 16 cups
2 gallons = 32 cups
3 gallons = 48 cups
Using ratio
4 cups of milk : 12 servings
48 cups of milk : x servings
4 : 12 = 48 : x
4 / 12 = 48 / x
Cross product
4 * x = 12 * 48
4x = 576
x = 576 / 4
= 144
x = 144 servings
3 gallons of milk = 48 cups of milk = 144 servings

If m7 is 100 find m3
Answer:
m3 is 100 degrees
Step-by-step explanation:
In this case, angle 7 is congruent to angle 5 because both their angles are located on the same place in different lines. Another rule you need to know is that angles across from each other are equal. So, if angle 5 is 100 degrees, then angle 3 is also 100 degrees because they are across from each other.

Prenell is filling his car with gasoline. Regular unleaded gas costs $1.89 per gallon. Which two equations show the proportional relationship between the total cost, c, and the price per gallon, p, of gasoline?
(more than one answer)
a. p=1.89c
b. c=1.89/p
c. pc=1.89
d. c=1.89p
e. p/c=1.89
f. c/p=1.89
Answer:
Step-by-step explanation:
For all Plato users.
c = 1.89p and c/p = 1.89 these two equation shows the proportional relationship between the cost c, and price p.
What is Proportionality Constant?Two sequences of numbers, often experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, which is called the coefficient of proportionality or proportionality constant.
Here, Total cost = $c
Price per gallon = $ 1.89
Total cost = Price per gallon X total units
c = 1.89 X p
c = 1.89p
or, c/p = 1.89
Thus, c = 1.89p and c/p = 1.89 these two equation shows the proportional relationship between the cost c, and price p.

Sheila is planning to move from New York to Arizona she obtained a price quote from two moving companies company a charge is a one time processing fee of $230 and $3.4 for every pound moved company Bb charges a one time processing fee of 270 and 280 for every pound moved part a right and expression that represents the right each company charges X represent the number of pounds to be moved part B if Sheila has a total of 1250 pounds of household items which company would charge less to move her items show your work and explain how you got your answer answer
Answer:
Company B will charge less to move her items
Step-by-step explanation:
A. Expression that represents the rate each company charges
Let x = number of pounds moved
Company A = 230 + 3.40x
Company B = 270 + 2.80x
B. If Sheila has a total of 1,250 pounds of household items
Substitute x = 1,250
Company A = 230 + 3.40x
= 230 + 3.40(1,250)
= 230 + 4,250
= 4,480
Company A = $4,480
Company B = 270 + 2.80x
= 270 + 2.80(1,250)
= 270 + 3,500
= 3,770
Company B = $3,770
Company B will charge less to move her items
a) 2x -1.5 = 2x - 1.5
-
b) 2v + 4 = -1
Answer:
a) all real numbers
b) v = -2.5
Step-by-step explanation:
a) 2x - 1.5 = 2x - 1.5
subtract 2x from both sides of the equation
2x - 1.5 - 2x = 2x - 1.5 - 2x
1.5 = 1.5
since 1.5 will always equal 1.5 regardless of what x is,
the solution is all real numbers
b) 2v + 4 = -1
subtract 4 from both sides of the equation
2v + 4 - 4 = - 1 - 4
2v = -5
divide both sides of the equation by 2
2v/2 = -5/2
v = -2.5

The regular price of an item is at a store in p dollars. The item is on sale for 20% off the eegular price. Some of the expression shown below represent rhe sale price in dollars of the item. Which two expression each represent the sale price of rhe item
Complete question :
The regular price of an item at a store is p dollars. The item is on sale for 20% off the regular price. Some of the expressions shown below represent the sale price, in dollars, of the item. Expression A: 0.2p Expression B: 0.8p Expression C:1 - 0.2p Expression D: p - 0.2p Expression E: p - 0.8p Which two expressions each represent the sale price of the item?
Answer:
Expression B: 0.8p ;
Expression D: p - 0.2p
Step-by-step explanation:
Given that:
Regular price = p dollars
Discount on price = 20%
Hence,
sale price = regular price - discounted price
Discounted price = 0.2 * p = 0.2p
Sale price = p - 0.2p
Or
Sale price = p - 0.2p = 0.8p
