Answer:
y = 5
x = 0
Step-by-step explanation:
soo i think elimination was this:
so first lets make -x = 3x
so we multiply -3 to the whole equation
3x + 3y = 15
now we eliminate (i think this is elimination)
3x + 5y = 25
-
3x + 3y = 15
----------------------------
0 + 2y = 10
2y = 10
y = 5
now substitute to one of the original equations
3x + 5(5) = 25
3x + 25 = 25
3x = 0
x = 0
now lets check
-0 -5 = -5?
-5 = -5

Answers
Answer:
62, the person in the comments helped me notice it was not as simple as it seemed.
The formula for finding perimeter is add all sides.[tex]23 + 6 = 29[/tex] « First two lengths
[tex]8 + 9 = 17[/tex] « Second lengths
[tex]23 - 9 = 14missing[/tex] « The missing length which was difficult for me
[tex]17 + 29 + 14 + 2 = 62[/tex] « Adding all lengths combined
Hope this helps. Let me know if it's right this time.
Answer:
62
Step-by-step explanation:
Ok so we have all but two identified lengths, but we can find them pretty quickly. To find the horizontal unidentified length, we can write 23-9=14 and get out length. To find the vertical length we can write 8-6=2 to get the length. Now add all lengths together 23+8+9+2+14+6=62 to get the perimeter. Just putting it here for the points :)

Answer:
1. x=25
2. x=6
Step-by-step explanation:
1. The angles of a triangle have to add up to equal 180 degrees so 180 minus 130 equals 50 and the two and that are unknown are the same so 50 divided by 2 equals 25
2. It is an isosceles triangle so the two sides are the same and if you plug in 6 for x you get the other missing side of the triangle as 24 as well.

16.3x42.7+22.5x16.3 = 1062.76 (approximately 1063)
Answer:
1063 cm^2
Step-by-step explanation:
notice you have 4 triangles. Take advantage of that!
the formula for a triangle:
[tex]\frac{base * height}{2}[/tex]
the triangles on the left side are the same so
2 * ([tex]\frac{42.7 * 16.3}{2}[/tex]) = 696.01 cm^2
I multiplied it by 2 because there are two corresponding triangles.
on the right side it's the same:
2 * [tex]\frac{22.5 * 16.3}{2}[/tex] = 366.75 cm^2
Now add those values: 696.01 + 366.75 = 1,062.76 cm^2
make sure you round to the nearest square centimetre: then the answer is 1063 cm^2.
You could also use the area of a rhombus.

Dudley Durite deposited $350 into a savings account that earns 6.5% interest compounded semi-annually. What amount was in his account at the end of 1-year?
Answers
Answer:
$373.12
Step-by-step explanation:
You want to set this up with the equation for compound interest which is [tex]A=P(1+\frac{r}{n})}^{nt}[/tex]. A stands for amount, P stands for principle which in this case is 350, r is rate which for this one is .065, ad n is the amount of times compounded per year, and since it is compounded semi annually you do 2 for 2 times a year. Your equation based on this information should look like this:
[tex]A=350(1+\frac{.065}{2})}^{(2)(1)}[/tex]
After working this out you get A = 373.12

if y²-x=7, find the positive value of when x=9.
Answers
Answer:
y = + 4
Step-by-step explanation:
y² - x = 7 ← substitute x = 9 into the equation
y² - 9 = 7 ( add 9 to both sides )
y² = 16 ( take square root of both sides )
y = ± [tex]\sqrt{16}[/tex] = ± 4
the positive value of y when x = 9 is + 4
Answer:
4
Step-by-step explanation:
when x = 9:
⇒ y² - 9 = 7
⇒ y² = 7 + 9
⇒ y² = 16
⇒ y = √16
⇒ y = ±4
Therefore, the positive value of y = 4

At a gymnastics meet, three judges evaluate the balance beam performances of five gymnasts, using a scale from 1 to 10, where 10 is a perfect score. A statistician wants to see if the gymnasts (Factor A) differ in their performances and also wants to see if the scores vary significantly across judges (Factor B) in order to assess any bias in the judges. To do this the statistician uses a two-way ANOVA without interaction and the results are show below. At 0.05 level of significance, what is the critical value for testing differences in mean scores across the Gymnasts
Answers
Answer:
As 2.551 < 3.84 therefore we reject H0.
As 44.803 > 4.46 so we accept null hypothesis.
Step-by-step explanation:
The answer is attached.
There are three judges so v1 = 3-1= 2 and v2 = (4*2)= 8
There are five gymnasts so v1 = 5-1= 4 and v2= (4*2)= 8
For alpha = 0.05 we find the value of F1 and F2 from the table.

Find the value of\xx, y.y, and zz in the parallelogram below.
Answers
Answer:
Step-by-step explanation:
The value of x, y, and z in the parallelogram are, - 40, - 60 and 1 respectively.
What is a parallelogram?A basic quadrilateral with two sets of parallel sides is known as a parallelogram.
The opposing or confronting sides are of equal length and the sum of the adjacent angles is of equal measure.
From the given diagram,
(- 3x - 3)° + 63° = 180°.
- 3x - 3° + 63° = 180°.
x = - 40.
Similarly,
(- 3x - 3)° + (- y + 3°) = 180°.
-3(-40) - 3° - y + 3° = 180°.
y = - 60.
And,
(- y + 3°) + (z - 4°) = 180°.
180° + 3° + z - 4° = 180°.
z = 1.
