Step-by-step explanation:
x=shortest side
one side =4
3x-5=long side
(3x-5)+x+4=19
4x-5+4=19
4x=20
x=5
long side = 3(5)-5=10

Penny, Amjit and James share some money in the ratio 3 : 6 : 4
Amjit gets $28 more than James.
Work out the amount of money that Penny gets.
Answer:
$42
Step-by-step explanation:
Let the amounts received by Penny, Amjit and James be 3x, 6x and 4x respectively.
According to the given information:
Amount received by Amjit = Amount received by James + 28
So,
6x = 4x + 28
6x - 4x = 28
2x = 28
x = 28/2
x = 14
Amount of money received by Penny = 3x = 3*14 = $42

The radius of a circle can be approximated using the expression √(A/3). A circular kiddie swimming pool has an area about 28 square feet. An inflatable full-sized circular pool has an area of about 113 square feet. How much greater is the radius of the full-sized pool than the radius of the kiddie pool? round to the nearest whole number.
It says Hint: First find the radius of each pool by substituting for A in the expression. Divide by 3 before approximating square root.
Answer:
yeah I know you are literally perfect for you to be home
By using the expression to approximate the radius of a circle, we want to compare the radius of the two pools. We will find that the radius of the full-sized pool is 2 times larger than the radius of the kiddie pool.
The expression for the radius of a circle is:
R = √(A/3)
Where A is the area of said circle.
The circular kiddie swimming pool has an area of 28ft^2, we just replace that in the above expression to get:
R = √(28 ft^2/3) = 3 ft
The full-sized pool has an area of 113 ft^2, then its radius is:
R' = √(113 ft^2/3) = 6 ft
To see how much greater is the radius of the full-sized pool than the radius of the kiddie pool, we just take the quotient:
R'/R = 6ft/3ft = 2
Meaning that the radius of the full-sized pool is 2 times larger than the radius of the kiddie pool.

Which of these is a correct identity?
x + 4x = 5x
6x = 18
2x + 1 = 7
7x + 9 = x
Answer:
x + 4x = 5x
Step-by-step explanation:
An identity is a mathematical equation that is always true (here - for all possible x's).
a). x + 4x = 5x; this is true, because for any possible x
x+4x = (1 + 4)x = 5x; there's not much to add.
b). 6x=18; evaluates to
x = 3; so it only works for one x, not all possible xs.
c). 2x + 1 = 7
2x = 6
x = 3; so it only forks for one x
d). 7x + 9 = x
6x + 9 = 0; we could compute the exact x it works for from here, but suffice to say this doesn't work for x = 0.
In between these given equations, x + 4x = 5x is the correct identity here.
What is an identity?"An identity is an equality relating one mathematical expression A to another mathematical expression B, such that A and B produce the same value for all values of the variables within a certain range of validity."
Given equations are:
1. x + 4x = 5x
⇒ 5x = 5x
This equation is true for all values of 'x'.
Hence, this is a correct identity.
2. 6x = 18
⇒ x = 3
This equation is true when x = 3.
3. 2x + 1 = 7
⇒ 2x = 6
⇒ x = 3
This equation is true when x = 3.
4. 7x + 9 = x
⇒ 6x = - 9
⇒ x = - 9/6
⇒ x = - 3/2
This equation is true when x = - 3/2.

If 2 fractions have the same numerator but different denominators, which fraction is greater? Give an example.
The question is incomplete, the complete question is;
two fractions have the same numerator, but different denominators. is the fraction with the greater denominator greater than or less than the fraction with the lesser denominator
Answer:
The fraction with the greater denominator is less than the fraction with the lesser denominator
Step-by-step explanation:
A fraction refers to a ratio of two number. A fraction has a numerator (The number on top) and a denominator (The number below).
If i have two fractions having the same numerator, then, the fraction with the greater denominator is less than the fraction with the lesser denominator.
Let me give you an instance, if i have 2/3 and 2/5.
We know that 5 > 3 hence 2/5 < 2/3

Aiko is selling books for $12 each. She wants to make more than $180 in book sales. The inequality 12b > 180 can be used to determine the number of books, b, she must sell in order to meet her goal. Which number line best represents the solution to the inequality?For which equation is x=5 a solution?
The third number line shows the inequality.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
Aiko is selling books for $12 each. She wants to make more than $180 in book sales.
and, the inequality 12b > 180 can be used to determine the number of books, b.
Now, solving the inequality
12b > 180
b > 180/12
b > 15
Hence, the third number line shows the inequality.

T = 4v + 3
(a)
(b) Make V the subject of the formula T = 4v + 3
The equation T = 4v + 3 is solved for v will be written as v = (T - 3) / 4.
What is the solution to the equation?The possible value of the variables that satisfy the equation which is known as the solution of the equation.
The equation is written below.
T = 4v + 3
The degree of the equation is one. Then the equation is given a linear equation.
Solve the equation for v, then we have
T = 4v + 3
Subtract 3 from both sides, then we have
T - 3 = 4v
Divide the equation by 4 into both sides, then we have
v = (T - 3) / 4
The equation T = 4v + 3 is solved for v will be written as v = (T - 3) / 4.
