Answer:
x=6
Step-by-step explanation:
3(x-2)=12
divide both sides by 3
x-2=4
add 2 to both sides
x-2+2=4+2
combine like terms
x=6
Answer:
x = 6
Step-by-step explanation:
So the equation looks like this:
3(x - 2) = 12
So the first thing we are going to do in this equation is multiply 3 by x and -2 in order to get rid of the parenthesis:
3(x - 2) = 12
(3 * x) + (3 * (-2)) = 12
3x - 6 = 12
Now we are going to add 6 to -6 and what you to one side of the equation you do to the other:
3x - 6 = 12
+ 6 + 6
3x = 18
Now in order to segregate the variable x from 3 we are going to have to divide 3x by 3 and what you do to one side of the equation you do to the other:
3x/3 = 18/3
x = 6
Now in order to check our work we are going to replace the variable x with six in the equation:
3(x - 2) = 12 = 3((6) - 2) = 12
(3 * 6) + (-2 * 3) = 12
18 - 6 = 12
12 = 12
Tada, hope this helps you!!
m<4=
degrees
*question in picture*
Answer:
38 degrees, see below :)
Step-by-step explanation:
Hello! :)
So, we can use the Base Angles theorem to say the angle with 62 degrees is equal to angle 1.
Now we know angle 1 = 62 degrees.
Next, we can use the exterior angles theorem to say that angle 3 is the sum of the remote interior angles of the triangle so:
angle 3 = 62 + angle 1
= 62 + 62
= 124
Now we know angle 3 = 124 degrees
We can find angle 4 by subtracting 18 degrees and angle 3 from 180 degrees because we know that they all have to add up to 180 so:
angle 4 = 180 - (18 + 124)
= 180 - 142
= 38 degrees.

Answer:
A. Genevieve
B. Sierra
Step-by-step explanation:
Genevieve uses 5 balloons per animal, but Sierra uses 6. We can find this by subtracting 360 from 440 (which gets us 80). To find the unit rate, we divide 20 into 80 (the amount of balloons used when she made 20 animals), and we get 4. So, Sierra uses 4 balloons per animal.
Since Genevieve uses more balloons per animal and started with less balloons than Sierra (she started with 425, versus Sierra, who started with 440), Sierra will have made more animals by the end of the day.
I hope this helps!

1) What is the nth term of the sequence?
2) Use the nth term to work out the 21st term of the sequence.
First difference,
[tex]\Delta_{1} = a_{2} - a_{1} = 3 - 1 = 2 = 1 + 1[/tex]
Second difference,
[tex]\Delta_{2} = a_{3} - a_{2} = 6 - 3 = 3 = 2 + 1[/tex]
Third difference,
[tex]\Delta_{3} = a_{4} - a_{3} = 10 - 6 = 4 = 3 + 1[/tex]
And so on.
Assuming the pattern holds on, we see that
i-th difference,
[tex]\Delta_{i} = a_{i + 1} - a_{i} = i + 1[/tex]
[tex]\implies a_{i + 1} = a_{i} + i + 1[/tex]
Then, nth term is,
[tex]\implies a_{n} = a_{n - 1} + n[/tex]
[tex]= a_{n - 2}+ (n + (n - 1))[/tex]
[tex]= a_{n - 3} + (n + (n - 1) +(n - 2))[/tex]
[tex]= a_{n - (n - 1)} + \sum \limits^{n - 2}_{k = 0}(n - k)[/tex]
[tex]= a_1 + \sum \limits^{n - 2}_{k = 0}n- \sum \limits^{n - 2}_{k = 0}k[/tex]
[tex]= a_1 +n(n -2 + 1 )- \frac{1}{2} (n - 2)(n - 1)[/tex]
[tex]= a_1 +n(n -1 )- \frac{1}{2} (n - 2)(n - 1)[/tex]
[tex]= a_1 +(n -1 )(n- \frac{1}{2} (n - 2))[/tex]
[tex]= a_1 + \frac{1}{2} (n -1 )(2n- n + 2)[/tex]
[tex]= a_1 + \frac{1}{2} (n -1 )(n + 2)[/tex]
[tex]\implies a_{n} = 1 + \frac{1}{2} (n -1 )(n + 2)[/tex]
Now, the 21st term in the sequence is,
[tex]\implies a_{21} = 1 + \frac{1}{2} (21 -1 )(21 + 2)[/tex]
[tex]= 1 + \frac{1}{2} \times 20 \times 23[/tex]
[tex]= 231[/tex]
The mass of the Eiffel Tower is about 9.16 ⋅ 106 kilograms. The mass of the Golden Gate Bridge is 8.05 ⋅ 108 kilograms. Approximately how many more kilograms is the mass of the Golden Gate Bridge than the mass of the Eiffel Tower? Show your work and write your answer in scientific notation.
Please help or im going to faill
Answer:
[tex]7.96 *10^8kg[/tex]
Step-by-step explanation:
Given
[tex]Eiffel = 9.16 * 10^6\ kg[/tex]
[tex]Golden\ Gate =8.05 * 10^8kg[/tex]
Required
Determine the difference in mass
This is calculated by subtracting the mass of Eiffel tower from the mass of Golden gate bridge
[tex]Difference = Golden\ Gate - Eiffel[/tex]
[tex]Difference = 8.05 * 10^8 - 9.16 * 10^6[/tex]
Express [tex]10^8[/tex] as [tex]10^6 * 10^2[/tex]
[tex]Difference = 8.05 * 10^2*10^6 - 9.16 * 10^6[/tex]
Express [tex]10^2[/tex] as [tex]100[/tex]
[tex]Difference = 8.05 * 100*10^6 - 9.16 * 10^6[/tex]
[tex]Difference = 805 *10^6 - 9.16 * 10^6[/tex]
Factorize:
[tex]Difference = (805- 9.16) * 10^6[/tex]
[tex]Difference = 795.84 * 10^6[/tex]
Factorize the decimal number
[tex]Difference = 7.9584 *10^2 * 10^6[/tex]
[tex]Difference = 7.9584 *10^8[/tex]
Approximate:
[tex]Difference = 7.96 *10^8[/tex]

7-(3,1-0,1у)=3-0,2у I NEED THIS TO BE ANSWERED RIGHT NOW PLEASE, I HAVE FAR AWAY SCHOOL AND IM STUCK ON THIS ONE
Answer:
y = -3
Step-by-step explanation:
Given the expression 7-(3.1-0.1у)=3-0.2у
We are to find the value of y as shown
7-(3.1-0.1у)=3-0.2у
Open the parenthesis
7-3.1+0.1y= 3-0.2y
3.9+0.1y = 3-0.2y
Collect like terms
0.1y+0.2y= 3-3.9
0.3y = -0.9
y = -0.9/0.3
y = -3
Hence the value of y is -3
