Find x.
x = 4
x = 5
x = 6
Answer:
Given triangles are similar
[tex] \frac{9}{6} = \frac{x}{4} \\\frac{3}{2} = \frac{x}{4} \\ x = \frac{(3 \times 4)}{2} \\ \boxed{x = 6}[/tex]
Value of x is 6.Write 1.625 x 1.625 using an exponent.
Answer:
1.625²
Step-by-step explanation!
1.625 x 1.625 is just 1.625 two times. So you add a 2 on the top which represents the number. You can write 1.625² instead of putting 1.625 x 1.625.
1.625 x 1.625 can be written in exponential form as [tex]1.625^2[/tex]
Given :
The given expression is 1.625 x 1.625 . we need to write it in exponential form
The exponent is in the form of [tex]b^x[/tex], where 'b' is the base and 'x' is the exponent
base is the number and x is the exponent that is repeating number of times
For example , [tex]2 \cdot 2 \cdot 2 = 2^3[/tex]
where 2 is the base and 2 is occurring three times
so exponent is 3
1.625 x 1.625 can be written in exponential form as [tex]1.625^2[/tex]

James and Anna share £42 in the ratio 4:3
Work out how much each person gets.
Use the terms 4, 12a 6 2a and 24 to make equivalent expressions use each term only once use substitution to prove that the expressions are equivalent
Answer:
12a + 24 = 6(2a + 4)
Step-by-step explanation:
Given the numbers :
4, 12a 6 2a and 24 ; create an equivalent expression :
12a, 2a, 4, 6, 24
We could separate tbe constant terms and those with variables :
12a, 2a ; 6, 4, 24
We could put the larger digit to one side
12a + 24 = 6(2a + 4)
This way the Right hand side is equal to the left hand side.
Check:
12a + 24 = 6(2a + 4)
12a + 24 = 12a + 24
Hence, the proof
Jamie's older brother and his three friends want to split the cost of lunch they also want to leave a 15% 20% tip how much should each person pay
Answer: See explanation
Step-by-step explanation:
Your question isn't well written but let me help out by making some assumptions.
Let's say Jamie's older brother and his three friends want to split the cost of lunch that costs $30 and they also want to leave a 20% tip. How much should each person pay?
Cost of the lunch = $30
Tip = 20% × $30 = 0.2 × $30 = $6
Total amount to be paid = $30 + $6 = $36
Since there are four people and they want to share the cost, each person would pay:
= $36 / 4
= $9

Answer:
one jumbo cost $4 and one chocolate cost $2
Step-by-step explanation:
Let the price eif one jumbo be x
Let the price of one chocolate be y
If one jumbo and 2 chocolate cost$6, then
x+2y= 6 ... 1
If one jumbo and 4chocolate cost $8, then;
x +4y = 8... 2
Subtract both equations
2y -4y = 6-8
-2y= -2
y = 1
Substitute y = 1 into 1;
From 1, x+2y = 6
x +2(1) = 6
x = 6-2
x = 4
Hence one jumbo cost $4 and one chocolate cost $2

Studying atoms helps people by providing research to common problems found in our environment, universe, and ourselves. Such as cleaning up oil spills, identification of atoms in our universe, etc.
Answer:
Many accounts of the atom begin with a history of the growth in scientists' understanding of its structure, but here we will take the opposite approach, first discussing the atom in terms of what physicists and chemists today understand. Only then will we examine the many challenges scientists faced in developing the current atomic model: false starts, wrong theories, right roads not taken, incomplete models. In addition, we will explore the many insights added along the way as, piece by piece, the evidence concerning atomic behavior began to accumulate. People who are not scientifically trained tend to associate studies of the atom with physics, not chemistry. While it is true that physicists study atomic structure, and that much of what scientists know today about atoms comes from the work of physicists, atomic studies are even more integral to chemistry than to physics. At heart, chemistry is about the interaction of different atomic and molecular structures: their properties, their reactions, and the ways in which they bond.
Step-by-step explanation:
Sample Response: "Studying atoms is important because knowledge about atoms helps people to understand the world around them and produce materials used in daily life. Also, research done on atoms has contributed to the improvement of people's lives through medicine, to the protection of the environment, and to the discovery of new things about the world and the universe."

Which of these strategies would eliminate a variable in the system of equations? \begin{cases} 2x - 5y = 13 \\\\ -3x + 2y = 13 \end{cases} ⎩ ⎪ ⎪ ⎨ ⎪ ⎪ ⎧ 2x−5y=13 −3x+2y=13
Answer and Step-by-step explanation:
Given the system of equations:
2x – 5y = 13
–3x + 2y = 13
We can decide to eliminate either x or y in order to solve the simultaneous equations.
1. To eliminate x:
Multiply the first equation by the coefficient of x in the second equation and multiply the second equation by the coefficient of x in the first equation. By doing this the coefficients of x in the equations would be the same and subtracting them to be equal to zero becomes easy, thus eliminating that variable.
The coefficient of x in the second equation is –3, if we multiply the first equation by it we have:
–6x+15y = –39
The coefficient of x in the first equation is 2, if we multiply the second equation by it we have:
–6x+4y = 26
Subtracting the resulting equations we have:
11y = –65 and x is eliminated.
2. To eliminate y:
Multiply the first equation by the coefficient of y in the second equation and multiply the second equation by the coefficient of y in the first equation. By doing this the coefficients of y in the equations would be the same and subtracting them to be equal to zero becomes easy, thus eliminating that variable.
The coefficient of y in the second equation is 2, if we multiply the first equation by it we have:
4x–10y = 26
The coefficient of y in the first equation is –5, if we multiply the second equation by it we have:
15x–10y = –65
Subtracting the resulting equations we have:
–11x = 91 and y is eliminated.

Answer:
The number of branches triples every 15 years.
Step-by-step explanation:
Satoshi started studying how the number of branches on his tree grows over time.
The relationship between the elapsed time t, in years, since Satoshi started studying the tree, and the number of its branches, N(t), is modeled by the following function:
N(t) = 24 - 3^t/15
Complete the following sentence about the growth rate of the branches. The number of branches triples every years.
The number of branches triples every 15 years.
What is a mathematical function, equation and expression? function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that the relationship between the elapsed time [t], in years, since Satoshi started studying the tree, and the number of its branches [N(t)], is modeled by the following function → N(t) = 24 - 3^t/15
The function that models the situation is -
N(t) = 24 - 3ⁿ/15 .... Eq[1]
After tripling the number of branches, we can write -
3N(t) = 24 - 3ⁿ/15
N(t) = {24 - 3ⁿ/15}/3 ..... Eq [2]
Equating both equations, we get -
{24 - 3ⁿ/15} = {24 - 3ⁿ/15}/3
3{24 - 3ⁿ/15} = {24 - 3ⁿ/15}
72 - 3ⁿ/5 = 24 - 3ⁿ/15
72 - 24 = 3ⁿ/5 - 3ⁿ/15
48 = 3ⁿ(1/5 - 1/15)
n = 15
Therefore, the number of branches triples every 15 years.
