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.

Guys can you please HELP!!?
Brian has reduced his cholesterol level by 15% after his last checkup. If his original level was 260, what is his cholesterol level now?
Answer:
His cholesterol level now is 221
Step-by-step explanation:
Convert 15% into a decimal, which is 0.15. Multiply that amount by 260.
0.15 x 260 = 39
Subtract 39 from 260, the original level
260 - 39 = 221

Given: RW ≅ WT; UW ≅ WS Prove: RSTU is a parallelogram. Quadrilateral R S T U is shown. Diagonals are drawn from point S to point U and from point R to point T and intersect at point W. The lengths of S W and W U are congruent. The lengths of R W and W R are congruent. Identify the steps that complete the proof. ♣ = ♦ = ♠ =
Answer:
♣ = ✔ vertical angles theorem
♦ = ✔ SAS
♠ = ✔ CPCTC
Step-by-step explanation:
This is the answer on Edge!! hope this helps!!!!!!
The steps that complete the two column proof are;
Vertical angles theorem, SAS Congruency postulate and CPCTC
What are congruent triangles?In the given parallelogram, we are told that RW ≅ WT; UW ≅ WS.
Now, from the given triangle attached we can say that;
∠SWR ≅ ∠UWT because of vertical angles theorem
Secondly, we can say that since ∠SWT ≅ ∠UWR by vertical angles theorem, then we can say that ΔSWR ≅ ΔUWT by SAS Congruency.
Lastly, since ΔSWT ≅ ΔUWR by SAS congruency rule then we can say that ∠WRS ≅ ∠WTU by CPCTC

x + 3y = 1 −3x − 3y = −15 solved by substitution please show work so i can understand
Answer:
x=7
y= -2
Step-by-step explanation:
x+3y=1 ---------------- (1)
−3x−3y=−15 -------------(2)
Solve Equation (1) for x
x=1−3y
Substitute x=1−3y in equation (2)
−3(1−3y)−3y=−15
−3+9y−3y=−15
−3+6y=−15
6y=−15+3=−12
y=−12/6=−2

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.

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.

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

O C. AKE
O D. AKEJ
ОЕ. ДЈЕ

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.

amount Kayla and Michael paid, including tax. Round your answer to the nearest cent.
Answer:
$1.06
Step-by-step explanation:
Kayla: 19 increase 6% =
19 × (1 + 6%) = 19 × (1 + 0.06) = 20.14
Michael: 18 increase 6% =
18 × (1 + 6%) = 18 × (1 + 0.06) = 19.08
Difference: 20.14 - 19.08 = 1.06
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.
