Answer:
Step-by-step explanation:
a=2d+3
b=3d-12
c=a+b so
c=2d+3+3d-12
c=5d-9
Answer:
2d + 3
Step-by-step explanation:
Dylan’s weight is d.
Twice Dylan’s weight is 2d.
Three pounds more than twice Dylan’s weight is 2d + 3.
So, the expression for Alan’s weight in terms of Dylan’s weight is 2d + 3.

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.

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
y=−2
Substitute y=−2 in equation (1)
x+3(−2)=1
x−6=1
x=1+6=7

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.

Kayla buys a video game for $19 plus a 6% tax. Michael buys a volleyball for $18 plus a 6% tax Enter the diference in the
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

♣ = ✔ 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

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.

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/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
