Mr. Edwards went to Six Flags and brought $50. He spent $20 on a souvenir and $10 on food. The rest was spent on a refillable drink at $2.50 per refill. How many refills did Mr. Edwards purchase?
Answer:
8 refills
Step-by-step explanation:
Set up an equation. You know that Mr. E spent his entire $50, so you start by making one side 50. Then, you know that the total is the same as the sum of everything purchased, so on the other side, add the souvenir, the food, and the refillable drink term (2.5x, with x being the number of refills, the thing the question is asking for). This gets you an equation of 50 = 20 + 10 + 2.5x. Isolate x by getting the x term by itself. In this case, you subtract 20 and 10 from both sides, leaving you with 20 = 2.5x. Finally, divide both sides by 2.5 to isolate x completely, leaving you with 8 = x, or x = 8. Don't forget your units (:
Answer:
8 refills

solve for x : -4 = (2/3)x
show steps please
To solve for x, we have to find a way to make x the subject of the equation (get x on one side and everything else on the other side)
since -4 = (2/3)x [mutiply both sides by 3]
⇒ -4 × 3 = 2x [divide both sides by 2]
⇒ (-12/2) = x [simplify by dividing -12 by 2]
∴ x = -6
Answer:
X = 6
Step-by-step explanation:
2/3 x 6/1 = 4
2 x 6 = 12
3 x 1 = 3
12/3 = 4
12 divided by 3 is 4
The answer is 6 , x = 6

The image shows the linear graph for a family that hired a babysitter for a day. The family gave the babysitter some money up front to buy herself some lunch, and then paid her a constant hourly rate for the hours she worked. Click the thumbnail image to see the full size image.
Which 2 of the following statements are TRUE about the Y-INTERCEPT of this line? Select the TWO statements that are accurate.
A.
The y-intercept is 0.
B.
The y-intercept is 10.
C.
The y-intercept tells me that they paid the babysitter $20 to buy her lunch.
D.
The y-intercept tells me that they paid the babysitter $10 to buy her lunch.
The y-intercept, which represents the point the graph crosses the y-axis, is the point where x = 0, or the usual start of a time based function
The true statements about the y-intercept are;
B. The y-intercept is 10
D. The y-intercept tells me that they paid the babysitter $10 to buy her lunch
Reasons:
The points on the graph are;
[tex]\begin{array}{|c|cc|} \mathbf{Time }&&\mathbf{Cost}\\0&&10\\1&&20\\2&&30\\3&&40\\4&&50\\5&&60\end{array}\right][/tex]
The slope of the graph is therefore; [tex]\dfrac{60 - 50}{5 - 4} = 10[/tex]
The equation of the graph is y - 60 = 10·(x - 5)
y = 10·x - 50 + 60 = 10·x + 10
y = 10·x + 10The y-intercept is give by the point where the x-value is zero
At the start when x = 0, the amount paid to the baby sitter is y = 10×0 + 10 = 10
Therefore, the y-intercept which is $10, represent the amount the family
paid to the babysitter at the start for her lunch
The correct statements are therefore;
Option B; The y-intercept = 10
Option D; The y-intercept indicates the amount given to the babysitter for
her lunch

One grain of this sand approximately weighs 7 x 10^-5 g. How many grains of sand are there in 6300 kg of sand ? Give your answer in standard form
Answer:
90 000 000 000 Grains
Step-by-step explanation:
one grain equal approximately 0.00007 grams.
convert 6300 kg into grams (multiply by 1000) and that equals 6 300 000g.
divide that by the weight of a single grain and you get the number of grains in that weight. So 6300000/0.00007=90 000 000 000 grains.
The number of grains of sand are there in 6300 kg of sand is 90,000,000.
What is scientific notation?Scientific notation is a method for expressing a given quantity as a number having significant digits necessary for a specified degree of accuracy, multiplied by 10 to the appropriate power such as [tex]1.56\times10^7[/tex].
Given that, one grain of this sand approximately weighs [tex]7\times10^{-5}[/tex] g.
6300 kg of sand
Number of grains = [tex]\frac{6300}{7\times10^{-5}}[/tex]
= [tex]900\times10^5[/tex]
= 90,000,000
Therefore, the number of grains of sand are there in 6300 kg of sand is 90,000,000.

Standard electrical voltage in Europe is 220 volts.
a. Find the impedance in a standard European circuit if the current is 22 - 11i amps.
b. Find the current in a standard European circuit if the impedance is 10 - 5i ohms.
c. Find the impedance in a standard European circuit if the current is 20i amps.
Applying the general Ohm's Law, it is found that:
a) The impedance is of 8 + 4i ohms.
b) The current is of 17.6 + 8.8i amperes.
c) The impedance is of -11i ohms.
Ohm's Law states that voltage is current multiplied by impedance, that is:
[tex]V = IZ[/tex]
Standard voltage of 220 volts, thus [tex]V = 220[/tex].
Item a:
Current is 22 - 11i amps, thus [tex]I = 22 - 11i[/tex]. Then:
[tex]V = IZ[/tex]
[tex]220 = (22 - 11i)Z[/tex]
[tex]Z = \frac{220}{22 - 11i} \times \frac{22 + 11i}{22 + 11i}[/tex]
Considering [tex]i^2 = -1[/tex]
[tex]Z = \frac{220(22 + 11i)}{605}[/tex]
[tex]Z = 0.3636(22 + 11i)[/tex]
[tex]Z = 8 + 4i[/tex]
The impedance is of 8 + 4i ohms.
Item b:
Impedance is 10 - 5i ohms, thus [tex]Z = 10 - 5i[/tex]. Then
[tex]V = IZ[/tex]
[tex]220 = (10 - 5i)I[/tex]
[tex]I = \frac{220}{10 - 5i} \times \frac{10 + 5i}{10 + 5i}[/tex]
[tex]I = \frac{220(10 + 5i)}{125}[/tex]
[tex]I = 1.76(10 + 5i)[/tex]
[tex]I = 17.6 + 8.8i[/tex]
The current is of 17.6 + 8.8i amperes.
Item c:
Current is 20i amps, thus [tex]I = 20i[/tex]. Then:
[tex]V = IZ[/tex]
[tex]220 = 20iZ[/tex]
[tex]Z = \frac{220}{20i} \times \frac{20i}{20i}[/tex]
[tex]Z = -\frac{220 \times 20i}{400}[/tex]
[tex]Z = -11i[/tex]
The impedance is of -11i ohms.

A line passes through the points (-6, -8) and (-3,-7).
What is the equation of the line in Slope-Intercept Form?
A)y=1/3x-6
B) y=3x-6
C)y=1/3x+6
D) y=3x+6
Step-by-step explanation:
For us to write the equation for this line, we need to (1) find the slope of the line, and (2) use one of the points to write an equation:
The question gives us two points, (-6, -8) and (-3,-7), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (-8 - (-7)) ÷ (-6 - (-3))
= -1 ÷ (-3)
= ¹/₃
Finding the Equation
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - (-7) = ¹/₃ (x - (-3))
we could also transform this into the slope-intercept form ( y = mx + c)
since y + 7 = ¹/₃ (x + 3)
⇒ y + 7 = ¹/₃ x + 1
∴ y = ¹/₃ x - 6

The length of a rectangle is 8 cm more then 4 times the with. If the perimeter of the rectangle is 46 cm, what are the dimensions
Answer:
15
Step-by-step explanation:
let the breadth be x
let the length be x+8
perimeter of rectangle=2 (length +breadth)
so, 2 (x+x+8)=44cm
=2 (2x+8)=44
=4x + 16=44
=4x= 44-16
=4x= 28
=x = 28÷4
=x= 7
therefore,
breadth is 7 (x)
length is 7+8 (x+8)
