If x+y−z=8 and x−y+z=12, then x=
Answer:
x = 10
Step-by-step explanation:
We see and show that x = 10
This makes y = 5 and z = 7 as 5-7 (y-z) = -2
As y5-z7 = -2 then we add 10 = 8
x+y-z = 10x-2yz = 8
x-y+z = 10 -5 +7 = 12 we know x = 10
We cna now prove.
x+y-z =8
x+5y-7z = 8
x +-2yz = 8
x = 8+2yz
x= 10
And prove
(x-5y)+7z= 12
x-y =12-7z
x = 5+5y
x=10
as x-5 (=5+7z) = 12

Determine the measure of obtuse angle A. answers: A) 130° B) 122° C) 58° D) 7°
Answer:
B) 122 degrees.
Step-by-step explanation:
Consider the kite :- the 2 angles at the tangents are 90 degrees so we have:
9x - 5 + 14x + 24 + 90 + 90 = 360
9x - 5 + 14x + 24 = 180
23x + 19 = 180
23x = 161
x = 7
So the obtuse angle = 14(7) + 24
= 98 + 24
= 122 degrees.

6 times _ equals 9
12 times _ equals 3
Answer:
6 times 1.5 equals 9. Essentially, this is just 1 and a half of 6, meaning you have 6, and half of 6, 3, together.
12 times 0.25 equals 3. Multiplying something by 0.25 has the same effect as dividing by 4, as both results in a quarter of the original number. Since 3 is a quarter, or 1/4 the size of 12, that means that multiplying it by 1/4 or 0.25 will give us 3.

Plot and connect the points A (2, -2), B (-4, -4), C (-4, -1), D (-2, 3), E (1, 3), F (2, 5), and find the length of BC.
Answer:
BC = 3 units
Step-by-step explanation:
Given points:
A = (2, -2)B = (-4, -4)C = (-4, -1)D = (-2, 3)E = (1, 3)F = (2, 5)Plot the points on the coordinate plane (x, y) and connect them in alphabetical order with straight lines (see attached).
From visual inspection of the drawn polygon, we can see that the length of BC is 3 units.
It is fairly simple to calculate the length of BC without plotting the points.
As points B and C have the same x-value, this means that the distance between them is simply the difference between their y-values.
⇒ distance = |-4 - (-1)| = |-3| = 3 units
Distance

(X/3 - 2)+(X/2 + 6)=3
Answer:
x=−6/5Step-by-step explanation:
\(\frac{x}{3} - 2 + \frac{x}{2} + 6 = 3\\\)
Simplify both sides of the equation:\(\frac{x}{3} - 2 + \frac{x}{2} + 6 = 3\)
\(\frac{1}{3} x + -2 + \frac{1}{2} x + 6 = 3\)
\(( 1/3x + 1/2x ) + ( −2+6 ) = 3\) (Combine Like Terms)\(5/6 x + 4 = 3\)
Subtract 4 from both sides:\(5/6x + 4−4= 3−4\)
\(5/6x = −1\)
Multiply both sides by 6/5:\((6/5) * (5/6x) = (6/5) * (−1)\)
\(x=−6/5\)
Today, after 10 days, the bean plant is 27 inches tall. How tall was it yesterday?
Answer:
23.48 inches
Step-by-step explanation:
Knowing that the plant grows 15% of its height every day, 27 inches would represent 115% of its height from the day before.
To find how it was yesterday, simply divide 27 inches by 115% (or 1.15).
27 inches/1.15 = 23.48 inches

Answer:
\(13.5 m^{2}\)
Step-by-step explanation:
area = length × width
= 15m × 9/10m
= 15m × 0.9m
= \(13.5 m^{2}\)
Answer:
\(\Huge \fbox{Area = 13.5 m^{2}$}\)
Step-by-step explanation:
To find the area of the baseboard, we need to multiply the length by the width:
The length of the baseboard is given as 15 metres. The width of the baseboard is given as \(\frac{9}{10}\) metre.To multiply these values, we can convert the width to a decimal by dividing the numerator (9) by the denominator (10):
\(\frac{9}{10} = 0.9\)Now we can multiply the length and width:
\(\text{Area = Length $\times$ Width}\)\(\text{Area = 15 m $\times$ 0.9 m}\)\(\text{Area = 13.5 m^{2}$}\)Therefore, the area of the baseboard is 13.5 m².

William is a very busy professional DJ. Last year, he worked at 10-anniversary parties and 26 other events.
What is the probability that one of the events William worked on last year, selected at random, was an anniversary party?
Write your answer as a fraction or whole number.
Answer:
hello
Step-by-step explanation:
The required probability that William worked on last year was an anniversary party is 1/ 36.
As mentioned in the quesiton,
William is a very busy professional DJ. Last year, he worked at 10-anniversary parties and 26 other events.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Total sample space = 26 + 10 = 36
Number of favorable outcomes = 1
the probability that William worked on last year is was an anniversary party,
= Favorable outcome/sample space
= 1 / 36
Thus, the required probability that William worked last year is 1/ 36.

The box plots show the weights, in pounds, of the dogs in two different animal shelters.
Weights of Dogs in Shelter A
2 box plots. The number line goes from 6 to 30. For the weights of dogs in shelter A, the whiskers range from 8 to 30, and the box ranges from 17 to 28. A line divides the box at 21. For shelter B, the whiskers range from 10 to 28, and the box ranges from 16 to 20. A line divides the box at 18.
Weights of Dogs in Shelter B
Which describes the spread of the data in the two box plots?
The data in shelter A show more spread than the data in shelter B.
The data in shelter B show more spread than the data in shelter A.
The data in shelter A range from about 17 to 28, while the data in shelter B range from about 16 to 20.
The data in shelter A range from about 21 to 28, while the data in shelter B range from about 18 to 20.
Answer:
The data in shelter A shows more spread than the data in shelter B
-And-
The data in shelter A range from about 17 to 28, while the data in shelter B range from about 16 to 20
For the range/span you look at where the actual box lies and for the spread use the whisker span.
