Aaron claims the same answer could also be found by adding either –5 + 3 or –3 + 5.
What is the error in Aaron’s reasoning?
Answer:
Step-by-step explanation:
-5 + 3 = -2 -5 is larger
5 + (-3) = 2 5 is larger
2 is larger than -2
Answer:
The negative signs were switched.
Step-by-step explanation:
Aaron claims the same answer could also be found by adding either –5 + 3 or –3 + 5.
What is the error in Aaron’s reasoning?
The commutative property is not true for addition.
The negative signs were switched.
The numbers are not in the correct order.
The associative property was used.

The recipe of a certain type of rice calls for 2:3 ratio to water . If you need to make 5 cups of rice , how much water should you use ?
Answer:
7 and 1/2 cups of water.
Step-by-step explanation:
Every 2 cups of rice, you need three cups of water. You make this equation, [tex]\frac{2}{3} \frac{5}{y}[/tex] and do cross multiplication to get 2y=15, divide that by two and end up with 7 1/2 cups of water.
help please and thank you
Answer:
D
Step-by-step explanation:
We assume the rotation R is counterclockwise 60°.
__
The exponent on R is the number of times it is applied. That is, R² = R(R(figure)). So, the composition is equivalent to R^(2-4) = R^-2.
When the exponent of R is negative, it is essentially the inverse function. That is, applying the function R to the result will give the figure you started with. Equivalently, it is rotation in the other direction.
[tex](\mathcal{R}^2\circ\mathcal{R}^{-4})(\text{figure})=\mathcal{R}^{-2}(\text{figure})=\text{figure rotated $120^{\circ}$ CW}[/tex]
The point 120° clockwise from B is D.
The desired image point is D.
expand (x-5)(x+2)(x+7)
Answer:
x³ + 4x² - 31x - 70
Step-by-step explanation:
Step 1: Expand (x - 5) and (x + 2)
(x - 5)(x + 2) = x² + 2x - 5x - 10 = x² - 3x - 10
Step 2: Expand (x² - 3x - 10) and (x + 7)
(x² - 3x - 10)(x + 7) = x³ - 3x² - 10x + 7x² - 21x - 70 = x³ + 4x² - 31x - 70

Writing What is the slope of the line which goes through the points (-3,-11) and (1,1)
The slope of the line is (Type an integer or a simplified fraction.)
Answer:
3
Step-by-step explanation:
[tex]m=\frac{rise}{run}=\frac{1+11}{1+3}=\frac{12}{4}=\boxed{3}[/tex]
The slope of the line would be 3.
Hope this helps.
Answer:
Slope = 3
Step-by-step explanation:
Let (x1,y1) = (-3,-11) and (x2,y2) = (1,1)
Slope = y2-y1/(x2-x1)
1-(-11)/(1-(-3) = 12/4 = 3

Suppose that a bike rents for $4 plus $1.50 per hour. Write an equation in slope-intercept form that models this situation. After how many hours will the bike rental cost a total of $10? Can you explain or show work so I can understand ?
Answer:
Equation: y=1.5x+4 Will total $10 after 4 hours
Step-by-step explanation:
Format: y=mx+b
y is total cost
m is per hour
b is starting cost
Equation: y=1.5x+4
After 4 hours, it will be $10 because:
10=1.5x+4
subtract 4 both sides
6=1.5x
divide 6 by 1.5
4=x
Hence the 4 hours answer

What is the slope of the line that passes through points (3,2) and (4,5)? *
Answer:3over1
Step-by-step explanation:
Answer:
3
Explanation:
The formula for the slope of a line is
[tex]\frac{ y_{2} -y_{1}}{x_{2} -x_{1}}[/tex]
In this case, the y2 would be 5 and the y1 would be 2
so the numerator would be 3.
The x2 would be 4 and the x1 would be 3 so the denominator would be 1.
The answer is [tex]\frac{3}{1} = 3[/tex]
What is the solution to the compound inequality 3x - 8≤ -5 or 2x – 7 > 5?

x ≤ 1 or x > 6
Is √3,600 rational or irrational? Please help asap.
Answer:
[tex]\sqrt{3600}[/tex] is rational
Step-by-step explanation:
A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The answer of square root of 3600 is 60 which is not a decimal or an irrational number and therefore it's rational
What is the measure of AngleDCF?
Three lines extend from point C. The space between line C D and C E is 75 degrees. The space between lines C E and C F is 54 degrees.
The measure of AngleDCF is
degrees.
Answer:
129°
Step-by-step explanation:
∠DCE = 75
∠ECF = 54
∠DCF = ∠DCE + ∠ECF
= 75 + 54
= 129°
Answer:
129
