At the beginning of the year, Alexa had $40 in savings and saved an additional $14 each week thereafter. Joshua started the year with $70 and saved $8 every week. Let AA represent the amount of money Alexa has saved tt weeks after the beginning of the year and let JJ represent the amount of money Joshua has saved tt weeks after the beginning of the year. Write an equation for each situation, in terms of t,t, and determine the amount of money Alexa and Joshua have saved in the week that they have the same amount of money saved.
Answer:
[tex]A=40+14t[/tex]
[tex]J=70+8t[/tex]
Amount of money Alexa and Joshua have saved in the week that they have the same amount of money saved is equal to $110.
Step-by-step explanation:
Initial amount as savings in account of Alexa = $40
Amount saved per week by Alexa = $14
Initial amount as savings in account of Joshua = $70
Amount saved per week by Joshua = $8
Amount saved by Alexa [tex]t[/tex] weeks after the beginning of the year (A) = [tex]\$(40+14t)[/tex]
[tex]A=40+14t[/tex]
Amount saved by Joshua [tex]t[/tex] weeks after the beginning of the year (J) = [tex]\$(70+8t)[/tex]
[tex]J=70+8t[/tex]
Now solve [tex]40+14t=70+8t[/tex].
[tex]70-40=14t-8t\\30=6t[/tex]
t = 5 years
[tex]A=40+14(5)=40+70=\$110\\J=70+8(5)=70+40=$110[/tex]
Answer:
110 dollars
Step-by-step explanation:
First equation: 14t+40
Second equation: 8t+70
Then find the value of t.
Equation: 14t+40= 8t+70
t=5. Then substitute the value of t into the first equation to get your final answer.
A car loses a quarter of its value every year. It is
originally worth $35,000. To the nearest dollar, how
much will the car be worth in eight years?
Answer:
Step-by-step explanation:
This is an exponential equation of the form
[tex]A=ar^2\text{ where a is the initial value r is the rate and t is the time.}\\ \\ A=35000(0.75)^8\\ \\ A\approx \$ 3504[/tex]
Which of the following are valid names for the triangle below? Check all that
apply.
А
R
O A. AJKE
B. AEJR
O C. AKE
O D. AKEJ
ОЕ. ДЈЕ
OF AJAOE
Answer:
A and D!
A-JKE
D-KEJ
Step-by-step explanation:
JKE and KEJ line up and are in the correct position and order to form the triangle listed by themselves. The other ones will not form even the same shape!
The reason why the other ones aren't elgible: EJR, KE and JE just form a line, and JAOE forms an uneven trapezoidal shape (forgot what it was called)
So that would leave JKE and KEJ, which are the only ones that line up.
The correct options are ΔJKE and ΔKEJ.
A and D are correct.
What is a Triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices.
As per the given data:
We are given the diagram of a triangle and we have to find out of the given options which ones can be the names of this triangle.
ΔJKE:
This is correct as J, K and E are the vertices and written in the correct order.
ΔEJR:
This is incorrect as R is not a vertex.
ΔKE:
This is incorrect, 3 points must be there.
ΔKEJ:
This is correct as J, K and E are the vertices and written in the correct order.
ΔJE:
This is incorrect, 3 points must be there.
ΔJAOE:
This is incorrect, 3 points must be there.
Hence, The correct options are ΔJKE and ΔKEJ.

A carpenter needs to cut 15-inch pieces of wood from a board of wood that is 11 feet in length.
What is the greatest number of 15-inch pieces the carpenter can cut from 6 of these wood boards?
Answer:
15-inch times 11 =165
Step-by-step explanation:
The greatest number of 15-inch pieces the carpenter can cut from 6 of these wood boards is 52.
Given that, cut 15-inch pieces of wood from a board of wood that is 11 feet in length.
We need to find the greatest number of 15-inch pieces the carpenter can cut from 6 of these wood boards.
How to convert inches to feet?Converting an inch length measurement to feet is as simple as dividing the number of inches by 12 because there are 12 inches in a foot.
Now, 11×6×12/15=52.8
Therefore, the greatest number of 15-inch pieces the carpenter can cut from 6 of these wood boards is 52.

Solve the system of linear equations by elimination. 11x−20y=28 , 3x+4y=36
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The value of x is 8.
The value of y is 3.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 7 is an equation.
We have,
11x - 20y = 28 ____(1)
3x + 4y = 36 _____(2)
Now,
Multiply 5 on (2).
11x - 20y = 28
15x + 20y = 180
26x = 208
This means,
x = 208/26
x = 8
Now,
11x - 20y = 28
11 x 8 - 20y = 28
88 - 20y = 28
88 - 28 = 20y
y = 60/20
y = 3
Thus,
The value of x is 8.
The value of y is 3.

Answer:
40+5q
Step-by-step explanation:
Distributive property is multiplying each number inside the parentheses by the number outside the parentheses.
For example: a(b+c) would be ab+ac
Knowing that all you have to do now is multiply:
5x8=40
5xq=5q
Put them together and you get 40+5q!

The values of d and p in the given expression are 13/4 and 30 respectively.
What is expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, are some expressions we need to perform operations to solve them,
1) 12x-2/3+2/3 [addition property]
= 12x
= 12x/12 [division property]
= x
2) 4d+5 = 13
Solving for d,
4d+5-5 = 13-5 [subtraction property]
4d = 13
4d/4 = 13/d [division property]
d = 13/4
3) 0.6p+4.5 = 22.4
Solving for p,
0.6p+4.5-4.5 = 22.4-4.5 [subtraction property]
0.6p = 18
0.6p/0.6 = 18/0.6 [division property]
p = 30
Hence, the values of d and p in the given expression are 13/4 and 30 respectively.

write 25 less than a number 4 as an expression
Answer:
y - 25 = 4
Step-by-step explanation:
i’m guessing you meant this as “25 less than a number = 4.” so i can put tha as an expression.
Basically you’re gonna want to take the unknown number and turn it into a variable.
You should know what a variable is but if not it’s just a letter in place for an unknown number.
so since the unknown number, we will use the letter y as the variable.
so y-25=4
boom that’s it.
since there’s an unknown number in place of the bigger number, we can just put the variable and write the rest out as a regular problem.
and if you need to know the variable number it’s 29.
