Answer:
Step 1 and step 2
Step-by-step explanation:
she has to subtract 30 not add 30.
2(3x+6)=3(x-10)
6x + 12 = 3x-30
6x +12 - 12 = 3x - 30 - 12
6x = 3x - 42
6x - 3x = 3x - 42 - 3x
3x = -42
3x/3 = -42/3
x = -14
Answer:
B
Step-by-step explanation:
Hey There!
So the first thing we're going to do is solve it and then compare it to Maya's steps to see where she made the mistake
2(3x+6)=3(x-10)
step 1 distribute the 2 to whats inside of the parenthesis (3x+6)
2*3x=6x
2*6=12
now we have
6x+12=3(x-10)
step 2 distribute 3 to what's inside of the parenthesis
3*x=3x
3*-10=-30
we're left with
6x+12=3x-30
step 3 add 30 to each side
12+30=42
now we have
6x+42=3x
step 4 subtract 6x from each side
3x-6x=-3x
now we have
-3x=42
step 5 divide each side by -3
42/-3=-14
so x = -14
now lets compare our steps to maya's
as we look at the steps we notice that she messes up on step 2
when distributing 3 to -10
she gets positive 30 but its supposed to be -30
so we can conclude that she mad a mistake from step 1 to step 2
therefore the second one is your answer

1) What is the surface area?
1 ft
8 ft
4 ft
Answer:
88 ft^2
Step-by-step explanation:
For a rectangular prism with dimensions 1 ft by 8 ft by 4 ft, there are two opposite faces with dimensions
1 ft by 8 ft,
two opposite faces with dimensions
1 ft by 4 ft,
and two opposite faces with dimensions
4 ft by 8 ft.
We find their area and add them.
SA = 2 * 1 ft * 8 ft + 2 * 1 ft * 4 ft + 2 * 4 ft * 8 ft
SA = 16 ft^2 + 8 ft^2 + 64 ft^2
SA = 88 ft^2
The highway mileage (mpg) for a sample of 8 different models of a car company can be found below. Find
the mean, median, mode, and standard deviation. Round to one decimal place as needed.
20, 22, 26, 27, 30, 31, 35, 35
Mean =
Median =
Mode =
Standard Deviation =
Mean = 28.3 , Median = 28.5, Mode = 35, Standard deviation = 5.2
(All of the above are rounded off to one decimal place)
How to find mean, median, mode ?
The given data are : 20, 22, 26, 27, 30, 31, 35, 35
We know that, mean = (sum of samples)/(no. of samples)
= (20+22+26+27+30+31+35+35)/8
= 226/8 = 28.25 = 28.3 (approx)
Here, median = (sum of 4th & 5th sample)/2
= (27+30)/2 = 57/2 = 28.5
Since 35 appears highest number of times, i.e. 2 times, then we can say that mode is equals to 35
What is the required standard deviation ?Standard deviation = √{(20-28.3)²+(22-28.3)²+(26-28.3)²+(27-28.3)²+(30-28.3)²+(31-28.3)²+(35-28.3)²+(35-28.3)²}/8
= √{68.89+39.69+5.29+1.69+2.89+7.29+44.89+44.89}/8
= √(215.52/8) = √(26.94) = 5.190 = 5.2 (approx)

Write in equation passing through the point that is parallel to (8,3); y=-1/4x+7
Answer:
y=-1/4x+5
Step-by-step explanation:
Use the point-slope form which is y-y1=m(x-x1) where m is the slope. In this case, y is equal to 3, and x is equal to 8, and the slope is equal to -1/4. Therefore, the equation will be equal to y-3=-1/4(x-8). Simplify that to get y-3=-1/4x+2. Simplify this again to get y=-1/4x+5. Therefore, the equation is y=-1/4x+5.
Answer:
y = -1/4x + 5
Step-by-step explanation:
Since the lines are parallel, they have the same slope, which is -1/4
Use the point-slope form to do this problem
[tex]y - y_{1} = m(x - x_{1})[/tex] Memorize this form. OK?
y - 3 = -1/4(x - 8)
4y - 12 = -1(x - 8) = -x + 8
4y = -x + 20
y = -1/4x + 5

Help please I will give you the brainliest
Answer:
x=15 degrees
Step-by-step explanation:
You know that the right angle is split in half to 45 degrees and 3x degrees. Because a right angle is equal to 90 degrees, 3x has to be equal to 45. Therefore, the equation will be 3x=45. You want to make x equal one so you have to divide 3 by each side. The equation will be x=45/3. Simplify that to get x=15. Therefore, x=15 degrees.
