a = 2 cm
b = 55 mm = 5,5 cm
c = 10 cm
d = 60 mm = 6 cm
Perimeter: 2 + 5,5 + 10 + 6 = 23,5 cm
y-3 = 2(x+1)
fiind the missing value ?
Step by step process:
Let's solve for x.
y−3=2(x+1)
Step 1: Flip the equation.
2x+2=y−3
Step 2: Add -2 to both sides.
2x+2+−2=y−3+−2
2x=y−5
Step 3: Divide both sides by 2.
2x/2=y−5/2
x=1/2y+(−5/2)
Answer: x=1/2y+(−5/2)
Let's solve for y.
y−3=2(x+1)
Step 1: Add 3 to both sides.
y−3+3=2x+2+3
y=2x+5
Answer:
y=2x+5
At the county fair, 12% of the
people who attended received
free water bottles. If 1,500 people
received free water bottles, how
many people went to the fair?
Answer:
12,500 people went to the fair.
Step-by-step explanation:
Set up an equation:
Variable x = number of people who went to the fair
12/100 = 1500/x
Cross multiply:
12 × x = 100 × 1500
12x = 150000
x = 12500
Check your work:
12500 × 12%
Convert percentage into a decimal:
12500 × 0.12
1500
1500 people received water bottles so this is correct!
A city has a population of 310 000 of people. Suppose that each year the population grows by 7.25%. What will the population be after 12 years?
This is an exponential growth problem.
The equation is: total = start value x ( 1 + rate)^time
Total = 310,000(1 + 0.0725)^12
Total = 718,008
Answer: 718,008
Write an equation for the line that is parallel to 8x + 2y = 4 and goes through (0,7)
Answer:
y = -4x +7
Step-by-step explanation:
First, we need to find the slope of the first equation
8x + 2y = 4
Subtract both sides by 8x
8x + 2y = 4
-8x -8x
2y = -8x + 4
Then divide both sides by 2 to isolate the variable, y
2y/2 = (-8x + 4)/2
y = -4x + 4
This means the slope is -4, so our other equation will need to have the slope of -4 to be parallel
y = -4x + ?
Wait, the equation also needs to be a line where it goes through (0,7)
Luckily, that just seems to be the y-intercept, so our work is cut out for us.
Here is our equation
y = -4x + 7
You can plug in the numbers to check
7 = -4(0) +7
7 = 0 + 7
7 = 7
If 2^10 + 2^10 = 2^x, what's x?
Answer:
11
Step-by-step explanation:
2^10 + 2^10 = 2^x
1024 + 1024 = 2^x
2,048 = 2^x
x = 11

I believe your answer is:

Here’s why:
⸻⸻⸻⸻
[tex]\boxed{\text{Solving for 'x'...}}\\\\2^{10}+2^{10} = 2^x\\--------------\\\rightarrow 2^{10} = 1024\\\\\rightarrow 1024 + 1024 = 2^x\\\\\rightarrow 2048 = 2 ^x\\\\\rightarrow log(2^x)=log(2048)\\\\\rightarrow xlog(2)=log(2048)\\\\\rightarrow \frac{log(2)}{log(2)} =\frac{log(2048)}{log(2)}\\\\\rightarrow x = \frac{log(2048)}{log(2)}\\\\\rightarrow \boxed{x = 11}[/tex]

Answer:
Ada is correct.
Step-by-step explanation:
Problems with Naman:
Naman is supposed to follow PEMDAS, which is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Division
Addition
Subtraction
~
The mistake: Naman moved +6 to the left and added it to the 2 located on the left side of the expression. You cannot do that, as it breaks the law of PEMDAS. On the other hand, Ada did the correct thing, which was to distribute 2 to all terms within the parenthesis (as one term in the parenthesis has a variable, and the other is a constant, meaning that they cannot be combined). This leads to Naman not doing the rest of the question correct.
Next, Ada correctly combined the two constants, which resulted in 0. 0 means nothing, therefore the placeholder is not needed. Therefore, 8x is the final answer.
What is the median of the following data values?
17, 19, 20, 21, 22, 25, 29, 30, 32, 35
O A. 24.5
O B. 22
O c. 25
O D. 23.5
Answer:
[tex]\boxed {\boxed {\sf D. \ 23.5}}[/tex]
Step-by-step explanation:
The median is the number in the middle of a set of data. To find, we place the numbers in order from least to greatest and pick the middle number.
The data set is:
17, 19, 20, 21, 22, 25, 29, 30, 32, 35This is already in order from least to greatest, so we can begin removing numbers from each side of the list until the middle is reached.
19, 20, 21, 22, 25, 29, 30, 3220, 21, 22, 25, 29, 30 21, 22, 25, 2922, 25Now we have 2 numbers that are in the middle. To find the median, we take the mean or average of these 2 numbers. Add them together, then divide by 2.
22 + 25= 4747/2 = 23.5The median of this data set is 23.5 and choice D is correct.

Solve for j.
–9j = 6j − 2(5j + 5)
j =
Answer:
-9j=6j-2(5j + 5)
-9j-6j=-2(5j+5)
-15j=-10j -10
-15j+10j=-10
-5j=-10
-5j/-5 =-10/-5
j=2
Step-by-step explanation:
-9j = 6j - 2 (5j + 5)
-9j = 6j - 10j - 10
-9j = -4j - 10
-9j + 4j = -10
-5j = -10
j = -10 / -5
j = 2
