-20y+16y= -4y
-4y+15=2+11
-11
-4y+4=2
-4
-4y=2
÷-4
y=-2
Answer:
The answer is y = 1/2
Step-by-step explanation:
-20y + 15 = 2 - 16y + 11 <----This is the original problem.
-20y + 15 = 13 - 16y <----- Use the commutative property and addition.
-20y + 15 = 16y -13 <-----Use commutative property.
-20y + 15 - 15 = 16y - 13 - 15 <----- Subtract 15 from both sides.
-20y = 16y - 2 <----- Simplify
-20y + 16y = 16y - 2 + 16y <------Add 16y to both sides.
-4y = -2 <---- Simplify
-4y/-4 = -2/-4 <---- Divide both sides by -4
y = 1/2

Answers
Answer:
Step 1. Perimeter P means adding up all three sides of a triangle.
Step 2. Then P=s+s+s=3s where s is the length of the side of the equilateral triangle.
Step 3. ANSWER: Perimeter P=3s.
I hope the above steps and explanation were helpful.
Step-by-step explanation:
HOPE THIS HELPS
Answer:
p = 3k
45cm
Step-by-step explanation:
Since all sides of an equilateral triangle are equal, to find perimeter, you multiply the number of sides by the length of one side.
So the equation would be p = 3k (k represents the side length and 3 is the number of sides)
If a equilateral triangle has a side length of 15, you just multiply 15 by the number of sides.
3 (15cm) = 45cm

Use a graph to find x and y values that make both y=-23x+3 and y=2x−5 true.
Answers
Answer:
y=x^2
Step-by-step explanation:
The graph of the equation y = - 23x + 3 and y = 2x - 5 is attached in the image below.
What is the graphical solution of a system of equations?Graphical solutions of a system of equations are a way of finding the intersection points of all the equations given.
A system with two or more than two equations has a solution only when they have a common intersection point.
Given, Are two equations y = - 23x + 3 and y = 2x - 5.
Subtracting equation 1 from equation 2 we have,
25x = - 8.
x = - 8/25.
y = - 2(8/25) - 5.
y = - 16/25 - 5.
y = (- 16 - 125)/25.
y = - 141/25.

Answers
Answer:
a
Step-by-step explanation:
An expression is a combination of numbers, variables, functions such as addition, subtraction, multiplication or division, etc.
The expression that shows the combined volume of the three boxes is 3.5x.
Option C is the correct answer.
What is an expression?An expression is a combination of numbers, variables, functions such as addition, subtraction, multiplication or division, etc.
We have,
Three box sizes:
Small, Medium, and Large.
The volume of the medium box is x.
The volume of the medium box = x ____(1)
The small box has half the volume of the medium box.
The volume of the small box = x/2 _______(2)
The large box has twice the volume of the medium box.
The volume of the large box = 2x _____(3)
Combining (1), (2), and (3) we get,
= x + x/2 + 2x
= (2x + x + 4x) / 2
= (7/2)x
= 3.5x
Thus the expression that shows the combined volume of the three boxes is 3.5x.
