how to solve 7x+(-3)=18
Answer:
x=3
Step-by-step explanation:
7x(-3)=18
add 3 to both sides
7x=21
divide by 7 on both sides
x=3
Answer:
7x+(-3)=18
7x-3=18
7x-3+3=18+3
7x=18+3
7x=21
7x/7=21/7
x=21/7
x=3

Ashleys Shoe Store buys shoes for $35 and then sells them for
$85.
What is the percent of increase on the price of the shoes?
Round to the nearest whole number
Step-by-step explanation:
% Increase = ((New value - Old Value) / Old Value) * 100
Given New value = $85
and Old Value = $35
% Increase =
[tex] (\frac{85 - 35}{35} ) \times 100 \\ = ( \frac{50}{35} ) \times 100 \\ = 143percent(nearest \: whole \: number)[/tex]

Costas has an after school job. He budgets his money, allowing 0.31 of his earnings for food and 0.58 of his earnings for entertainment. The rest of the money he saves. If he earns $67.50 per week, which is the best estimate of the amount of money he saves each week ?
Answer: the amount of money he saves a week is $19.56
Step-by-step explanation: I am assuming that you mean percent so you subtract the percentages ($67.50 - 58%) - 31% This should give you a remaining amount of $19.56

explain how to isolate the variable in the equation -2/3+7=15
Answer:
n= -12
Step-by-step explanation:
- 2n/3 + 7=15 Subtract 7 from both sides and move all terms containing
-7 = -7 n to the right
- 2n/3 = 8 multiply both sides of equation by - 3/2
-3/2 x (-2n/3) = -3/2 x 8
n= -3/2 x 8 cancel the common factor of 3
n= -12

PLEASE HELP ME FIND THE DISTANCE OF THE DIAGONAL
Step-by-step explanation:
Let x be the diagonal distance,
by pythagoras' theorem,
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
where c is the diagonal
a and b are the 2nd and 3rd longest side, interchangeable.
given a = 50m, b = 25m,
[tex] {c}^{2} = {50}^{2} + {25}^{2} \\ {c}^{2} = 2500 + 625 \\ {c}^{2} = 3125 \\ c = \sqrt{3125} \\ = 55.9m \: (nearest \: tenth)[/tex]

Answer:
A. 117.2 cubic feet
Step-by-step explanation:
Volume of the cone = ⅓πr²h
Where,
r = 4 ft
h = 7 ft
π = 3.14
Substitute
Volume = ⅓*3.14*4²*7
Volume = 117.226667 ≈ 117.2 cubic feet

find the perimeter of the figure
Answer:
(19x+10)/2
Step-by-step explanation:
Perimeter of the figure is the sum of all the sides
Perimeter of the figure = 4x+3 + x+2+2x+2 + x/10 -1 + 2x/5 + 2x-1
Perimeter of the figure = 4x+x+2x+2x+x/10+2x/5 + 3 + 2 + 2 -1-1
Perimeter of the figure = 9x + (x+4x)/10 + 5
Perimeter of the figure = 9x + 5x/10 + 5
Perimeter of the figure = 9x + x/2 + 5
Perimeter of the figure = (18x+x)/2 + 5
Perimeter of the figure = 19x/2 + 5
Perimeter of the figure = (19x+10)/2

Answer:
20 and 25
Step-by-step explanation:
The solution is, The mode and median are 7.
What is median?In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.
here, we have,
From the given dot plot, we can find the values.
Each X symbol corresponding to a number in the horizontal axis represents a value.
So, the data set can be written as,
3, 6,6,6,6,6,6,6, 7,7,7,7,7,7,7,7, 8,8,8,8,8,8, 9,9,9, 10,10
An outlier is value that lies outside the other values in the given data.
7 is a value which is close to the other values in the data set.
Hence, 7 is not an outlier.
Therefore, the statement "there is an outlier at 7 " is incorrect.
The total number of values can be found by counting the numbers in the data set after aarranging it in numerical order.
The total number of values in the data set is N=27.
The median is the middle value in a given data set.
Since N is odd, the position of the median is
median = 14
Since 7 is the 14 th value in the data set, the median is 7.
Mode is the value which repeats frequently in the given data set.
Since 7 is the most repeated value in the data set, 7 is the mode of the data set.
Hence, the statement "The mode and median are 7" is correct.
The range of a data set is the difference between the highest and the lowest values in the data set.
Hence, the range of the given data set is,
Hence, the statement " The range of the given data set is 10" is incorrect.
A dot plot is positive skewed if majority of the data is located to the right of the plot. The given dot plot is not positively skewed.
Hence, the statement " The data shows a positive skew" is incorrect.
Final Answer:
The mode and median are 7
