The equation would be -9+-9 = -18
Answer:
-9 + (-9) = -18
Step-by-step explanation:
They start on -9 and end on -18. That means -9 has to be an addend and -18 is the sum.
-18 - (-9) = -18 + 9 = -9, which means the other addend is also -9.
Hope this helps!

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
Answers
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

hi there user! Looks like your looking for help, so Mizuki came here to help you!
the answer is:

Brainlist for positive attitude and correct answer :D
Answers
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

Please help me quickly!!
Answers
Answer:
<
Step-by-step explanation:
the exponent will tell you how many places u need to move the decimal. 5.7 × 10 to the 2nd power = 570. u moved the decimal 2 places to the right.
If we interpret the statement correctly "5.7 x 5,700,000,000,000" means to multiply 5.7 with 5,700,000,000,000, which gives us the result of 32,490,000,000,000.
Therefore, we can write the statement as: 5.7 x 5,700,000,000,000 = 32,490,000,000,000.

1. 4t + 3.5 =12.5

2. 8m - 5.5 =10.1
what is m equal to
Answers
Step-by-step explanation:
This is the answer that you want
t=9/4
m=1.95
Answer:
t = 2.25 and m . 1.95
Step-by-step explanation:
4t + 3.5 = 12.5
to start, isolate the variable by subtracting 3.5 from both sides
4t = 9
then, divide both sides by 4 to find what t is equal to
t = 2.25
8m - 5.5 = 10.1
isolate the variable by adding 5.5 to both sides
8m = 15.6
then, divide both sides by 8 to find what m is equal to
m = 1.95

The base of the pyramid below is a square that has an area of 64 square inches.
Suppose that the pyramid is sliced so that the cross-section is a square with an area of 49 square inches.
How can you slice the pyramid to get that square?
Answers
The height of the pyramid must be sliced by a factor of 7/8
How to slice the pyramid to get the square?From the question, we have the following parameters that can be used in our computation:
Area of base of the pyramid = 64 square inches.Area of cross-section of the pyramid = 49 square inches.The base length of the pyramid is
L^2 = 64
L = 8
For the cross-section, we have
l^2 = 49
l = 7
Using the similar shapes, we have the height h to be
(L - l)/h = l/L
So, we have
(8 - 7)/h = 8/7
This gives
1/h = 8/7
Evaluate
h = 7/8
This means that the height of the pyramid must be sliced by a factor of 7/8

Answer: consistent and dependent
Step-by-step explanation:
For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.
Joshua has 2 ¾ times as many stamps as Leo. How many stamps must Joshua give to Leo so that each of them will have 210 stamps?
Show your work
Answers
Answer:
Joshua has to give Leo 93.75 (or 93 3/4) of his stamps
Step-by-step explanation:
210x2=240
210/4=52.5
52.5x3=157.5
157.5+240
So Joshua has 397.5 stamps
397.5-219=187.5
So there's a 187.5 difference
187.5/2=93.75
397.5-93.75=303.75
210+93.75=303.75
