Which equation has no solution A.) 4(x+3)+2x=6(x+2) B.) 5+2(3+2x)=x+3(x+1) C.) 5(x+3)+x=4(x+3)+3 D.) 4+6(2+x)=2(3x+8)
Answers
Answer:
B. 5+2(3+2x)=x+3(x+1)
Step-by-step explanation:
Expand the brackets.
5 + 6 + 4x = x + 3x + 3
11 + 4x = 4x + 3
Add -4x and -11 on both sides.
4x - 4x = 3 - 11
0 = -8
There are no solutions.
Answer:
B
Step-by-step explanation:
I could explain this to you by using process of elimination but I think it would be easier to explain to you straight forward why answer choice B has no possible answers. First I did the equation out on a piece of paper:
5 + 2(3 + 2x) = x + 3(x + 1)
5 + 6 +4x = x + 3x +3
11 + 4x = 4x +3
Now we have 4x + 3 = 4x + 11. It is impossible for 4x to be added to two entirely different numbers and still produce the same outcome, so that is why B is the correct answer choice.
find jh in triangle HIJ

Answer:

\(2 \times area \div height \:\)
Step-by-step explanation:
the answer is 5
Answer:
JH=16
Step-by-step explanation:
Hi there!
We are given ΔHIJ, where HI is parallel to KL, and that JK=10, JI=40, and JL=25
We want to find JH
We can use something called the Triangle Proportionality Theorem to help us find JH
The Triangle Proportionality Theorem essentially states that if there is a line parallel to one of the sides of a triangle that intersects the other 2 sides of that triangle, then that segment divides those sides proportionally
In other words, KL is parallel to HI and intersects both HJ and JI, and JK, JH, JL, and JI create a proportion, which is \(\frac{JK}{JH} =\frac{JL}{JI}\)
We can substitute the values that we know into that equation
\(\frac{10}{JH} =\frac{25}{40}\)
We can simplify 25/40 to 5/8.
\(\frac{10}{JH} =\frac{5}{8}\)
Now we can cross multiply (use the means-extreme theorem)
Multiply 10 and 8 together, and set that equal to 5 times JH
80 = 5JH
Divide both sides by 5
16=JH
Hope this helps!

Answer:
% change in perimeter = 43. 44 %
% change in area = 16 %
Step-by-step explanation:
initial perimeter of the rectangle = 2(2p + p)
= 6p
initial area of the rectangle = 2p × p
= 2p²
25% is equal to 0.4therefore,
new length = 2p + (2p × 0.4)= 2p + 0.8p = 2.8 p
new breadth= p - 0.4p
= 0.6 p
new perimeter = 2 ( 2.8 p + 0.6p)= 3.4 p
new area = 2.8p × 0.6p= 1.68 p²
% change in perimeter
\( = \frac{6p - 3.4p}{6p} \times 100 \\ = \frac{2.6p}{6p} \times 100 \\ = 43.33\%\)

If Jamal treated his family with a family brunch and the brunch costs $250 and the sales tax was 4%. If Jamal left an 18% tip on the $250. How much did he pay in total?
Answers
The total amount jamal paid is $305.
Given:
Jamal treated his family with a family brunch at the cost of $250.
The sales tax was 4%.
The tip is 18%.
to find the sales tax.
\(\begin{gathered} =250\cdot4\text{ \%} \\ =250\cdot\frac{4}{100} \\ =\frac{1000}{100} \\ =10 \end{gathered}\)The amount he paid for sales tax is $ 10.
to find the tip.
\(\begin{gathered} =250\cdot18\text{ \%} \\ =250\cdot\frac{18}{100} \\ =\frac{4500}{100} \\ =45 \end{gathered}\)Jamal left a tip of $45.
Thus the total amount paid by Jamal is,

Dange measures and finds that she can do a vertical jump that is27.5 % her height f dange can jump 13.2 inches how tall is she
Answers
The height of Dange who can jump 27.5% of her height is 10.4 inches.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, Dange measures and finds that she can do a vertical jump that is 27.5 % of her height f and the distance of the jump is 13.2 inches.
Therefore. (100 + 27.5)% = 127.5% of f is 13.2 inches, This can be numerically expressed as,
(127.5/100)×f = 13.2.
1.275f = 13.2.
f = 13.2/1.27.
f = 10.4 feet.
So, The height of Dange is 10.4 inches.

Answers
Let x be the amount invested at 9% and y the amount invested at 6%.
Then we have:
I) x + y = $14,929
II) 0.09x - 0.06y = $1,139.91
First, we multiply equation II by 100:

Now, we add to it 6 times equation I:
15x = $203,565
x = $13,571
Now, we replace x in equation I to find y:
$13,571 + y = 14,929

We can solve this a super simple way.
The midpoint is (-6,-3/2) and the coordinate B is (-1,3)
We notice that we change y by positive 5 and we change our x by negative 3/2, from M to B. So to get to A from M, we change y by -5 and change our x by positive 3/2...

The value of the 18th percentile for the data set of n=31 scores from 121 to 167 summarized by the given stem and leaf plot is: O 152 O 133 O 127
O 133.5
O None of these
Answers
A leaf plot, also known as a stem-and-leaf plot, is a way of displaying numerical data by separating each value into a "stem" and "leaf" and organizing them in a table for easy analysis.
To find the value of the 18th percentile for this data set, we need to first determine how many scores fall below that percentile.
Since there are 31 scores in total, the 18th percentile would correspond to the score at the 0.18(31) = 5.58th position when the scores are listed in ascending order. However, since we are given a stem-and-leaf plot rather than the raw data, we need to estimate the position of the 18th percentile based on the plot.
Looking at the plot, we can see that there are a total of 31 scores, with 12 of them falling in the range from 120 to 139 (inclusive) and 9 of them falling in the range from 140 to 159 (inclusive). This means that the 18th percentile must be somewhere in the first group of scores.
To estimate the exact position, we can use the fact that the 12 scores in the first group represent 12/31 = 0.3871 (rounded to 4 decimal places) of the total number of scores. To find the position of the 18th percentile within that group, we can multiply that fraction by the number of scores in that group:
0.3871 x 12 = 4.6452 (rounded to 4 decimal places)
So the 18th percentile falls somewhere between the 4th and 5th scores in the first group. Looking at the stem-and-leaf plot, we can see that the 4th score is 127 and the 5th score is 133.
Therefore, the value of the 18th percentile for this data set is between 127 and 133.5 (since we know it falls between the 4th and 5th scores in the first group, and there is a gap of 0.5 between adjacent scores).
The answer choices given are 152, 133, 127, and 133.5. Of these, the only one that falls within the range we just determined is 133. Therefore, the answer is:
O 133
