Step-by-step explanation:
8×4=12°
20×4=80°
17×4=64
12+80+64=180
8x+20x+17x=180
add all together,
20+8=28+17=45
180/45=4
your answer is 4
to check sub x for 4
8x4=32
20x4=80
17x4=68
68+32=100
100+80=180
X=4

Answer:
A
Step-by-step explanation:
Sila put a wrong number in her calculator
Sila jogged 12 kilometers today and wants to know how far she traveled in feet. What error did Sila make while converting from kilometers to feet ? The correct answer is Option a) Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction times Start Fraction 5280 feet Over 1 mile End Fraction = 392,832 feet.
Sila's mistake can be identified in her conversion calculation. She first needs to convert kilometers to miles and then miles to feet. Let's break down the process step by step:
1. Kilometers to Miles:
Start by converting kilometers to miles.
There are 0.62 miles in 1 kilometer.
So, the first fraction is correct:
Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction.
2. Miles to Feet:
Next, convert miles to feet.
There are 5280 feet in 1 mile. Sila's calculation is incorrect at this step. The correct fraction to use here is Start Fraction 5280 feet Over 1 mile End Fraction.
Now, let's put it all together:
- Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction times Start Fraction 5280 feet Over 1 mile End Fraction
Multiply the fractions step by step:
- 12 kilometers * 0.62 miles/kilometer * 5280 feet/mile
- This simplifies to 392,832 feet.
So, Sila's error lies in not using the correct conversion factors for both kilometers to miles and miles to feet.
The correct conversion factors should be applied in sequence, leading to the final answer of 392,832 feet traveled.

Step-by-step explanation:
27 divided by 9 equals 3 and the ^2 is 3x3 Which equals 9 and then the negative comes
Answer:
-9
Step-by-step explanation:
In this, you should use PEMDAS, parentheses, exponents, multiplication, division, addition, subtraction. It is the order of solving any equation. The first thing you should start with is the parentheses. -27/9 is -3. Since exponents come next, you would do -3 x -3, which equals 9. After that, all that is left is a negative sign being multiplied to 9 (which is in the parentheses still. The negative sign times 9 equals -9. Therefore, your answer is -9. You could check through just in case, but I hope its correct. Also, if you don't mind, could you mark brainliest? I would really appreciate it :D

A local farmer started the year with 56 farm animals. At the end of the year, the farmer had 63 farm animals. What was the percent of change? (Show work)
Answers

Answer:
The answer is a increase of 12.5%
Step-by-step explanation:
The equation to find this is new minus old divided by old times 100, so it would be 63 minus 56 divided by 56 which gives you 7 over 56 times 100. 7 over 56 times 100 equals 12.5 so 12.5% is the answer

18 + 7 = 7 + 18
18 + 7 = 7 + 18
4 + (1 + 11) = (4 + 1) + 11
Answers
According to the Associative property of Addition, when 3 or more numbers are added, the result (sum) remains the same even if the numbers are grouped in a different way. Here, grouping is done with the help of brackets.
This can be expressed as, a + (b + c) = (a + b) + c.
So, according to this the answer is 4 + (1 + 11) = (4 + 1) + 11.

What is the equation of this graphed line?
Enter your answer in slope-intercept form in the box.
Answers
Answer:
y = 2x + 2
Step-by-step explanation:
As we know, slope intercept is: y = mx + b
m is slope and b is the y-intercept.
Looking at this problem, we can see that the line crosses the y-axis at positive 2, so that is our y-intercept. For the slope, take a point like the y-intercept, and see how many squares is has to go up before it reaches the next square to the right. In this problem the line goes up 2 squares in the time it takes to go to the right 1. So the slope is y over x, or 2 over 1, or just 2.
