Answer:
1. 13= 13 2. 17> 7 3. 30>9. 4. 30> 3
Answer:
a ) x + 3 = 11, x = 8
b) 3x = 9, x = 3
c) x - 7 = 7, x = 7
d) 3x = 3, x = 1
Step-by-step explanation:
a) There is one green rectangle and 3 yellow triangles on one side and 11 yellow squares on the other side. They're on that thing where in order to balance each side has to be equal, so one green rectangle + 3 yellow squares = 11 yellow squares.
the green thing is x, the yellow thing is 1.
add them up, which makes the equation x + 3 = 11
subtract 3 from both sides
x = 8
You do the same process with each equation.
Hope this helps!
Use the drawing below to answer the questions that follow.
16 feet 8 feet
-------------------l l-------------------------
l11 feeet l
l ? feet l
Answer:
Part A: k=1/2
Part B: 5.5 feet
Step-by-step explanation:
Part A: To go from 16 to 8, you have to divide by 2 (or multiply by 1/2). Since the scale factor is always multiplication, you need to multiply by 1/2.
Part B: Using the scale factor of 1/2, multiply 11 by 1/2 and you will get 5.5.
Match the lines m and n to the statements they represent:
- A set of points where the coordinates of each point have a sum of 2
- A set of points where the y-coordinates of each point is 10 less than its x-coordinate
Match the labeled points on the graph to statements about their coordinates:
- Two numbers with the sum of 2
- Two numbers where the y-coordinate is 10 less than the x-coordinate
- Two numbers with a sum of 2 and where the y-coordinate is 10 less than the x-coordinate
Answer:
see explanation!
Step-by-step explanation:
Line N
A set of points where the coordinates of each point have a sum of 2Line M
A set of points where the y-coordinates of each point is 10 less than its x-coordinate
Any coordinate on N has a sum of 2.
Any coordinate on M has a y that is 10 less than the x.
The matching is shown below.
What are Coordinates?Coordinates are two integers (Cartesian coordinates) or a letter and a number that point to a specific place on a grid known as a coordinate plane. A coordinate plane has four quadrants and two axes: x (horizontal) and y (vertical).
First, A set of points where the coordinates of each point have a sum of 2
- Any coordinate on N has a sum of 2.
A set of points where the y-coordinates of each point is 10 less than its x-coordinate
- Any coordinate on M has a y that is 10 less than the x.

Answer:
120πcm²
Step-by-step explanation:
Since we are keeping this in terms of pi, you do not necessarily need a calculator. I will be doing my calculations as simple as I can.
First we need to figure out the area of the top circle and bottom circle.
We know that the formula for the area of a circle is:
πr²
So we need both circles, our formula becomes:
2πr²
Let's substite our radius in.
2 × π × 4² = 32πcm²
Now we need to find the area of the sides itself. Our formula here is:
2 × π × r × h
Let's substitute our radius and height in:
2 × π × 4 × 11 = 88πcm²
Let's now add both of these together:
88πcm² + 32πcm² = 120cm²
Remember to add your measurements!

Write a series of two transformations that would form a similar but not congruent image. Explain how you can know the figures will be similar without graphing.
Answer:
That is, they're similar if one is congruent to a rescaling of the other. So if two figures are congruent, they are also similar. If they are similar, they are not necessarily congruent.

How do you solve a y=mx+b equation if x is unkown?
example -
y = 1.29x+2
How do I solve that? Please make sure to explain :) thanks!
Answer
Y= 2 x= -0.645
Step-by-step explanation:
you basically plug 0 into x and y
y=1.29(0)+ 2
y=2
0=1.29x+ 2
Answer:
Okay so "y = mx+b is a linear equation that represents a line on a graph; m represents the slope of the line and b is the y-intercept (The y-intercept of this line is the value of y at the point where the line crosses the y axis.)
In y = 1.29x+2, 1.29 is equal to m, so that is your slope.
The 2 is equal to the b so your y-intercept is 2.
Here's a graph to better understand it :)
