3. Which equation illustrates the associative
property of addition?
A. (x + y) + 3 = x + (y + 3)
B. 3(x + y) = 3x + 3y
C. x + y = y + x
D. x + 0 = x
Answer: C. x + y = y + x
Step-by-step explanation:
Answer:
A. (x + y) + 3 = x + (y + 3)
Step-by-step explanation-
The associative property of addition allows the numbers grouped within the parenthesis to be switched with the other numbers in the equation to make the problem easier to solve.

whats the equation for the perpendicular bisector of the line segment whose endpoints are (-5,3) and (3,7)?
Answer:
The equation of perpendicular bisector of the line segment passing through (-5,3) and (3,7) is: [tex]y = -2x+3[/tex]
Step-by-step explanation:
Given points are:
(-5,3) and (3,7)
The perpendicular bisector of line segment formed by given points will pass through the mid-point of the line segment.
First of all we have to find the slope and mid-point of given line
Here
(x1,y1) = (-5,3)
(x2,y2) = (3,7)
The slope will be:
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{7-3}{3+5}\\m = \frac{4}{8}\\m = \frac{1}{2}[/tex]
The mid-point will be:
[tex](x,y) = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})\\ = (\frac{-5+3}{2},\frac{3+7}{2})\\= (\frac{-2}{2},\frac{10}{2})\\=(-1,5)[/tex]
Let m1 be the slope of the perpendicular bisector
Then using, "Product of slopes of perpendicular lines is -1"
[tex]m.m_1 = -1\\\frac{1}{2}.m_1 = -1\\m_1 = -1*2\\m_1 = -2[/tex]
We have to find the equation of a line with slope -2 and passing through (-1,5)
The slope-intercept form is given by:
[tex]y = mx+b\\y = -2x+b[/tex]
Putting the point (-1,5) in the equation
[tex]5 = -2(-1)+b\\5 = 2+b\\b = 5-2\\b = 3[/tex]
The final equation is:
[tex]y = -2x+3[/tex]
Hence,
The equation of perpendicular bisector of the line segment passing through (-5,3) and (3,7) is: [tex]y = -2x+3[/tex]

A milk truck delivers 457 dozen gallons of milk to stores in 1 day. Write and solve an equation to find g, the number of gallons of milk the milk truck delivers in 1 day I don't get it help!
Answer:
5484 gallons
Step-by-step explanation:
Given that:
Delivery in 1 day = 457 dozen gallons
g = number of gallons delivered on that day
Recall :
1 dozen = 12
Therefore, the number of gallons delivered in 1 day :
457 gallons * 12 = 5484 gallons
What is the answer?
Answer:
read explanation
Step-by-step explanation:
rearrange equations to form y=mx+b
-2x+4=2y
-x+2=y
-y=-2x-5
y=2x+5
use these equations to find slope and y intercepts, and match those with the right graph

The top running speed of a giraffe is 250% of the top speed of a squirrel. If a squirrel’s top running speed is 12 miles per hour, find the speed of a giraffe.
Answer:
30
Step-by-step explanation: First take the fastest speed of the squirrel, and then you multiply it by the percentage (250%). You can this by moving on decimal point to the left from the zero (250% = 2.50). Then multply the speed of the squirrel by said percentage of the girrafe,
12 x 2.5 = 30

PLEASE EXPLAIN HOW YOU GOT IT!!!!
Answer:
−r^3+r^2+r
Step-by-step explanation:
Let's simplify step-by-step.
r^2(r+1)−r(2r^2−1)
Distribute:
=(r^2)(r)+(r^2)(1)+−2r^3+r
=r^3+r^2+−2r^3+r
Combine Like Terms:
=r^3+r^2+−2r^3+r
=(r^3+−2r^3)+(r^2)+(r)
=−r^3+r^2+r

Answer: t= 11.5
Step-by-step explanation: 5 + (-11.5+3) = 3.5
Answer:
T = -3.7
Step-by-step explanation:
We begin with the given equation.
5(t+3)=-3.5
Distribute 5 throughout parentheses.
5t + 15 = -3.5
Move 15 to the other side and switch signs.
5t = -3.5 - 15
Combine like terms.
5t = -18.5
Divide by 5t.
t = -3.7

Solve. Express your answer as a mixed number. 5 feet= ______ yards Solve. I need an explanation on how to put it as a mixed number and how to solve it.
Answer: 5 feet= __5/3 0r 1 2/3____ yards
Step-by-step explanation:
Step 11 yard = 3 feet
3 feet = 1 yard
5 feet = 5feet x 1 yard/ 3feet
= 5/3yards
Step 2 To convert 5/3 yards to a mixed fraction,
1. We first Divide the numerator, 5 by the denominator, 3 giving us a whole number and a remainder
5/3 = 1 remainder 2
2.then we write the whole number and put the remainder 2 above the denominator 3 giving us
5/3 = 1 2/3
such that when you multiply the mixed fraction 3 x 1 and add 2 it gives back the improper fraction of 5/3
