Answer:
(-5, -8); the missing value is -8
Step-by-step explanation:
First, you need to simplify the given equation to isolate y
1: -3x + 7y = 5x + 2y (Given)
2: 7y = 8x + 2y (Add 3x to both sides)
3: 5y = 8x (Subtract 2y from both sides)
4: y = 8/5x (Divide both sides by 5)
Now, you can use this to solve for the missing y in value set (-5, y)
where y = 8/5x and x = -5,
y = 8/5(-5)
y = -8
so, the missing value is -8

Step-by-step explanation:
5x-3+ x+9 + 90= 180
6x+ 96=180
6x=180-96
6x=84
x=84/6
x=14
A bag contains eleven balls labeled 1 through 11. One ball will be randomly picked. What is the probability of picking a multiple of 3? Write your answer as a fraction in simplest form.
Answer:
3, 6, 9 (the multiples of three within 11)
3 out of 11 numbers are multiples of 3
so you have a 3 out of 11 probability to grab a multiple of three
3/11 is your answer
Step-by-step explanation:
Probability of picking a ball of multiple of 3 is equals to (3/11).
What is probability?
" Probability is a mathematical expression which represents the ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
'B' represents the ball
Possible outcomes = { B₁, B₂, B₃, ...., B₁₀, B₁₁}
favourable outcomes multiple of 3 = { B₃, B₆, B₉}
Total number of outcomes= 11
Number of favourable outcomes = 3
Substitute the value in the formula we get,
Probability of picking ball multiple of 3 = ( 3 / 11)
Hence, probability of picking a ball of multiple of 3 is equals to (3/11).

22 lb/day ≈ ____________ oz/h
Answer:
there are 16 ounces in a pound and 24 hours in a day.
22*16= 352oz/day
352/24 = 14.66666 oz/h
i would round up because it has the about symbol. so your answer is:
15 oz/h
Step-by-step explanation:
i multiplied 22 by 16 to find out how many ounces were in 22 pounds.
i divided 352 by 24 because there's 24 hours in a day and i needed how many ounces for one hour.

If a triangle has three sides with the lengths 20, 16, and 12, what are the angles?
Answer:
angle a = 53.13°
angle b = 36.87°
angle c = 90°
Step-by-step explanation:
The following is one way to perform the calculation. It may not be the best way.
Calculates ∠A, ∠B, ∠C based on given a, b and c.
∠A = arccos( b2 + c2 - a2 2bc )
= 0.9273 rad = 53.13° = 53.13°
∠B = arccos(a2 + c2 - b2 2ac )
= 0.6435 rad = 36.87° = 36.87°
∠C = arccos(a2 + b2 - c2 2ab )
= 1.5708 rad = π/2 = 90°

Y-9=4/5(X+7)
Find the value of x in the isosceles triangle
Step-by-step explanation:
Since all 3 sides of the triangle is equal, it is not only an isosceles, but an equilateral triangle.
x = 8sin60° = 6.928 or sqrt48.
That is a question about triangles.
In my answer I will show 2 ways to solve that question, ok? Let's go.
First way - Pythagoras's theoremThe line segment x divide the biggest triangle in 2 equals right triangles.
Let's choose one of them and note that is a triangule with hypotenuse equals to 8 and one cathetus equals to half of 8.
The Pythagoras's theorem says that:
[tex]\boxed{a^2 = b^2 + c^2}[/tex]
a is the hypotenuse and b and c are cathetus.
So, in our case, we know the hypotenuse and one cathetus, let's substitute that in the expression:
[tex]a^2 = b^2 + c^2\\8^2 = 4^4 + c^2\\64 = 16 + c^2\\c^2 = 64 - 16\\c^2 = 64 -16\\c^2 = 48\\c = \sqrt{48}\\c= 4\sqrt{3}[/tex]
Therefore, the value of x is [tex]4\sqrt{3}[/tex].
Second way - The equilateral triangle heightThat way to solve the question is a consequence of the previous way.
That triangle has all the sides equals, so it is a equilateral triangle.The line segment x is the height of that triangle. And we can find the equilateral triangle height using that expression:
[tex]\boxed{h = \frac{S\cdot \sqrt{3} }{2} }[/tex]
h is the height and S is the triangle's side.
So, we know that the side of our triangle is 8. Let's change S value in the expression:
[tex]h = \frac{S\cdot \sqrt{3} }{2} \\h = \frac{8\cdot \sqrt{3} }{3} \\h = 4\sqrt{3}[/tex]
Thus, the value of x is [tex]4\sqrt{3}[/tex].
Note that in the 2 ways we find the same result, so that answer is correct.
I hope I've helped. :D

Answer:
82 units
Step-by-step explanation:
There are multiple ways to go about solving this problem (solving by calculating the areas of the individual, smaller shapes), but I recommend solving it by first calculating the area of the entire figure (96 units - 12 * 8 - length * width ((formula for the area of a rectangle)) and then subtracting the area of the missing part from this value.Assume the opposite sides are equal in value (see picture for work) and subtract the given values (4 and 5) from 8 and 12 to get the measurements to find the triangle (the missing part).You get 7 and 4 and now you use the formula for the area of a triangle to get the area. (7*4)/2, which gives you 14 units.Subtract 14 (area of missing value) from 96 (area of total value) to get your final answer, 82 units!from least to greatest 42%,0.43,17/40

Tim’s age is nine more than his sister, Jill. Twice his age added to twice Jill’s age is 330.
Answer:
jill age is 78 and tim's age is 87
Step-by-step explanation:
let jill age be x then, tim's age is 9+x
by the question,
2(9+x) + 2x = 330
or,18 + 2x + 2x = 330
or,4x = 330-18
or, x = 312÷4
x = 78
9+x= 9+78=87
