Answer: get the 2 perfums in the size 50ml
Step-by-step explanation:
80ml is 55 pound
50 ml is 45 pound
2nd is half of 45 pound which is 22.5
the 2 perfum in the size 50 ml with the special price is: 45 + 22.5 = 67.5 now per ml is 0.675 pound per ml i found the price per pound by dividing the ml by the price
for the 80ml the price per ml is 0.6875
solve using substitution
-5x+7y=-5
y=-5
x=?
So if you solve for x using the first equation, you get: x = 5y - 5.
From there you can plug that into the second equation which would give you:
7y-5y+5=-23
Simplifying from that point, you get y = -9.
Now that you have one of the values, you can solve for x by plugging it back into the equation we made (x = 5y - 5) and getting to the answer x = -40.
A jet travels 470 miles in 2 hours. At this rate, how far could the jet fly in 11 hours?
Answer:
The jet will cover 2585 miles in 11 hours.
Step-by-step explanation:
Given that:
Distance travelled by jet in 2 hours = 470 miles
Speed of jet = [tex]\frac{Distance}{Time}[/tex]
Speed of jet = 470/2
Speed of jet = 235 miles per hour
Time = 11 hours
Distance travelled in 11 hours = Speed * Time
Distance = 235 * 11
Distance = 2585 miles
Hence,
The jet will cover 2585 miles in 11 hours.
which graph represents y=3x+2
Step-by-step explanation:
The general form of a straight line is y = mx + c, where m is the line's slope and c is the y-intercept.
For y = 3x + 2, the slope is positive 3 and the y-intercept is 2. The line should rise up and pass through the point (0, 2).
We are between Options B and C.
In Graph B, the line raises by 4 units for every 2 units across. Hence its slope is 4/2 = 2.
In Graph C, the line raises by 3 units for every 1 unit across. Hence its slope is 3/1 = 3.
Since we want 3 as the slope,
The answer is Option C.
The graph C represents y=3x+2

can someone please help me graph y=2/3x-4
Answer:
Look at the picture attached.
Step-by-step explanation:
Your x-intercept is 6 and your y-intercept is 4, that is where your 2 points will go. According to the slope, you should go up 2 and over 3, if you don't want to find the x-intercept. Then you would just plot the y-intercept which is 4, and then go up 2, over three and plot the next.

How many cubic meters of water are required to fill a rectangular swimming pool 15m long and 10 m wide which is 2m deep throughout.How many liters is that?
Answer:
300,000 liters
Step-by-step explanation:
Let us have the measurements in cm
100 cm = 1 m
so the measurements are multiplied by 100
we have this as;
1500 by 1000 by 200
The volume is the product of the 3
This is :
1500 * 1000 * 200 = 300,000,000 cm^3
Mathematically, 1 liter = 1000 cm^3
300,000,000 cm^3 will be ;
300,000,000/1000 = 300,000 liters

A tax of 7% was added on to the cost of a meal. If the tax paid was $1.40, what was the cost of the meal?
Answer:
The cost of meal is: $20
Step-by-step explanation:
Given
Percentage of tax = 7%
Also given that the amount of tax is $1.40
Let x be the price of meal
Then the tax will be 7% of x
It can be written mathematically as:
[tex]1.40 = 7\%\ of\ x[/tex]
We will simply solve this equation to get the price of meal
So,
[tex]1.40 = 0.07*x\\x = \frac{1.40}{0.07}\\x = 20[/tex]
Hence,
The cost of meal is: $20

If k ∈ A ∩ B, which is the most specific location of k on the Venn diagram?
I
II

Answer:
Zone II
Step-by-step explanation:
k ∈ A ∩ B means k is an element of both A and B.
zone II is in between zone I and zone III which is both.
The most specific location of k on the Venn Diagram is II.
What is Venn Diagram?Venn diagram is a diagram denoting two or more sets which is drawn using circles inside a rectangle where the part where the two circle meet denotes the intersection of two sets.
Given is a Venn Diagram.
U represents the Universal set.
There are 2 sets, set A and set B, which are represented by 2 circles.
I represents the location of elements which are in A alone.
II represents the location of elements which are in B alone.
If an element belongs to A ∩ B, then the element contains both in A and B.
This is the location marked as II.
Hence the location of k will be in II.

The cost of a game g with 7% sales tax can be represented by the expression g + 0.07g. Simplify the expression. Then determine the total cost of the game after sales tax if the original price is $52. (Remember that the coefficient of g is 1).
Answer:
$58.64
Step-by-step explanation:
The total cost of a game g with 7% sales tax can be represented by the expression
g + 0.07g
From the above question,
g = Original price of the game = $52.
The total cost of game g =
$52 + 0.07 × $52
$52 + $3.64
= $58.64

All of the following are equivalent except____.
4y
(4)(y)
4•y
4+y
Answer:
All the options are equivalent except;
4 + y
Step-by-step explanation:
The question relates to the number of ways the operation of a multiplication operation can be represented algebra
1) The coefficient of a variable is a multiplier of the variable
Therefore;
4y = 4 × y
2) When given two numbers or variables in a mathematical expression that are separated by parenthesis, then it is an indication that the two numbers are meant to be multiplied
Therefore;
(4)(y) = 4 × y
3) The dot symbol, '·', placed between two numbers, a number and a variable or two variables, is a representation of multiplication of the two quantities
Therefore;
4·y = 4 × y
However, multiplication, and addition are different mathematical operations that produce different results when applied;
Therefore;
4 + y ≠ 4 × y.
