Find the missing angle measures.
Y = 63
Z = ?
X = ?
Answer:
Step-by-step explanation:
y = 63 {Vertical angles are congruent}
y + z + 85 = 180 {Angle sum property of triangle}
36 + z + 85 = 180
z + 121 = 180
z = 180 - 121
z = 59
63 + x = 130 {External angle property of triangle}
x = 130 - 63
x = 67

The correct question can be found at https://brainly.com/question/25052574
We are given the equation;
9(x + 6) − 41 = 75
Step 2;
Using addition property of equality, we add 41 to both sides;
9(x + 6) - 41 + 41 = 75 + 41
9(x + 6) = 116
Step 3;
Using distributive property to distribute 6 over the items in the bracket to get;
9x + 54 = 116
Step 4; Using subtraction property of equality, we subtract 54 from both sides;
9x + 54 - 54 = 116 - 54
9x = 62
Step 5; Using division property of equality, we divide both sides by 9 to get;
9x/9 = 62/9
x = 62/9

How do you do this? Am I corrdct
Answer:
1/20 is the correct answer
Step-by-step explanation:
65/100 diet
30/100 caffeine
Of the 65/100, 22 are caffeine free but that is unnecessary info for the question. The 22 caffeine free would fall under the 65/100 anyways.
So 65 + 30 = 95
100-95 = 5
5/100 simplified is 1/20
Yes, you are correct . Since we know 65 sodas are diet and 30 are caffeine-free.
65 + 30 = 95
What plus 95 equals 100?
95 + x = 100
Or 100 - 95 = 5
= 5/100
When 5/100 is simplified, it equals 1/20.

find all of the zeros of
If f(x) = x3 + 13x2 + 32x + 20 and f(-10)=0
pls help with this problem !
Answer:
Step-by-step explanation:
Well you have one of the roots -- -10. Just by looking at it, -1 would seem to be another x intercept.
f(x) = (-1)^3 + 13(-1)^2 + 32(-1) + 20
f(x) = -1 + 13 - 32 + 20
f(x) = 0
So - 1 is also a root.
You should try -2
-2 * -10 - 1 = - 20
f(-2) = (-2)^3 + 13(-2)^2 + 32(-2) + 20
f(-2) = -8 + 13 * 4 - 32(2) + 20
f(-2) = - 8 + 52 - 64 + 20
f(-2) = -72 + 72
f(-2) = 0
The zeros are
x = -10
x = -1
x = -2

what does x equal in the equation
-4(x-1) + 6x = 2(17-x)
Step-by-step explanation:
since -4(x-1) + 6x = 2(17-x) [expand the bracket]
⇒ -4x +4 + 6x = 34 - 2x [group like terms across the equal sign]
⇒ -4x + 2x + 6x = 34 - 4 [simplify like terms]
⇒ 4x = 30 [divide both sides by 4]
⇒ x = ³⁰/₄ [simplify RHS to lowest possible fraction]
⇒ x = ¹⁵/₂Check:
-4((¹⁵/₂) - 1) + 6(¹⁵/₂) = 2(17-(¹⁵/₂))

By what least number should 4851 be divided to get a perfect square number ? Also find the square root of the square number so obtained ?
Answer:
The least number should 4851 be divided to get a perfect square number = 11
The square root of the obtained perfect square number is 21
Step-by-step explanation:
Given number = 4851
It can be written as
4851 = 3×1617
4851 = 3×3×539
4851 = 3×3×7×77
4851 = 3×3×7×7×11
4851 = (3×3)×(7×7)×11
It is clear that We should divide the given number by 11 then we get a perfect square number.
4851/11 = 441
441 = 21×21
=> 441 = 21²
=> √441 = √(21²)
=> √441 = 21
Answer:-The least number should 4851 be divided to get a perfect square number = 11
The square root of the obtained perfect square number is 21
Used Method :-→ Prime Factorization Method
Answer:
11 is the least number and the when you take the square root of the number you get 21
Step-by-step explanation:
The easiest way to solve this problem is guess and check.
First of all, a perfect square NEEDS to be a WHOLE number
Since 4851 is odd, you cannot divide it by an even number evenly, as it would result in a number with a remainder or leftover decimal amount.
This means you cannot divide by 2, 4,8...etc
We just have to guess and check odd numbers starting at 3.
4581/ 3 = 1527 sqrt(1527) = 39.07684737 decimal so not this one
4581/ 5 = 916.2 decimal so not this one
4581/ 7 = 654.4285714 decimal so not this one
4581/ 9 = 509 sqrt(509) = 22.56102835 decimal so not this one
4581/ 11 = 441 sqrt(441) = 21
This is the first instance where 4581 is divisible by a number that yields a perfect square, so 11 is the least number and the square root of the result is 21.

The length of each piece be 3.25 inches.
What is a expression? What is a mathematical equation? What do you mean by domain and range of a function?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which [y] exists.We have Trinity who has 48.75 inches of ribbon. She cut the ribbon into 15 equal-sized pieces.
Assume that the length of each piece be [x]. Then, we can write -
15x = 48.75
x = 48.75/15
x = 3.25 inches
Therefore, the length of each piece be 3.25 inches.

9/10 - (1/8-3/10)= please help me through steps
Answer:
43/40 or 1 3/40
Step-by-step explanation:
9/10 - (1/8 - 3/10)
Remember, we have to solve what's in the parentheses first!
To find 1/8 - 3/10, we must find the least common multiple of the denominators, which is 8 and 10.
Let's list the multiples of 8 and 10
Multiples of 8: 8, 16, 24, 32, 40, 48, 56...
Multiples of 10: 10, 20, 30, 40, 50, 60...
We found a match! 40 is a multiple of both 8 and 10, so we can use that.
To make the denominator 40 for 1/8, we have to multiply both the numerator and denominator by the same number, and the denominator must equal 40 after.
So,
8 times what equals 40?
To make it easier, we can do 40 / 8, which is 5.
That means we multiply the denominator and numerator by 5, so we get 5/40 - 3/10.
If you do the same thing for 3/10, you get 12/40.
Our equation is much easier!
We can easily do 5/40 - 12/40, which is -7/40.
Now, we do 9/10 - (-7/40)
Remember, two minuses right next to each other make a plus!
Our equation is now 9/10 + 7/40.
If you do the least common multiple for 9/10, you get 36/40.
Finally, we do 36/40 + 7/40, which is 43/40.
If it's asking for a mixed number, it would be 1 3/40.
Therefore, 9/10 - (1/8 - 3/10) equals 43/40 or 1 3/40!
Hope this helped :)
Solve -4(10 + 3x) - (x + 8) = -9. Check your solution.
Answer:
x = -3
Step-by-step explanation:
Given the equation, -4(10 + 3x) - (x + 8) = - 9:
Distribute -4 into (10x + 3x), and - 1 into (x + 8):
-4(10 + 3x) - (x + 8) = - 9
-40 -12x - x - 8 = -9
Combine like terms:
-48 - 13x = -9
Add 48 to both sides:
-48 + 48 - 13x = -9 + 48
-13x = 39
Divide both sides by -13:
[tex]\frac{-13x}{-13} = \frac{39}{-13}[/tex]
x = -3
Therefore, x = -3

Answer:
It will be 381. You round up if it is five and over, and round down if 5 and below.
Step-by-step explanation:
A decimal cannot be a whole number so rounding to the nearest whole number means getting rid of the decimal. You do this by rounding up if it 5 and up, and rounding down if it is 5 and below. 380.5 means you would round up to 381. If it it were 380.4, you would round down to 380.

A line passes through the points (-2,-4) and (3, 5). Which equation best represents a line
parallel to this line?
A) y = -5/9x+ 4
B) y = 9/5x + 4
C) y = 1x + 4
D) y = -4/3x + 4
The equation best represents a line parallel to the given line is y = 9/5x - 2/15.
What is the equation of line?The general equation of a straight line is
y = mx + c,
where m is the gradient, and y = c is the value where the line cuts the y-axis.
This number c is called the intercept on the y-axis.
Now it is given that the line passes through (-2,-4) and (3,5).
So here,
x1 = -2;
y1 = -4;
x2 = 3;
y2 = 5
Hence slope of the line is given as,
m1 = (y2 - y1)/(x2 - x1)
⇒ m1 = {5-(-4)}/{3-(-2)}
⇒ m1 = (5+4)/(3+2)
⇒ m1 = 9/5
Since both the lines are parallel, hence
m1 = m2 = 9/5
Therefore equation of line parallel to the given line will be,
(y - y1) = m2( x - x1)
⇒ {y-(-4)} = 9/5{x - (-2)}
⇒ y + 4 = 9/5(x +2)
⇒ y + 4 = 9/5x + 18/5
⇒ y = 9/5x + 18/5 - 4
⇒ y = 9/5x - 2/15
Hence, The equation best represents a line parallel to the given line is y = 9/5x - 2/15.

All I know is that it is acute and less than 51 degrees
Answer:
AOB is 39 degrees.
Step-by-step explanation:
Given that ∠DOE is 51 degrees we know that ∠AOE is 180 degrees as it is a straight line.
∠BOD is a right angle given the ∟symbol so therefore ∠BOD is equal to 90 degrees.
m∠DOE + m∠BOD = 141 degrees (because 51 + 90)
Therefore m∠AOB = 39 because 180 - 141 = 39
Straight angles are equal to 180! Hope this helped
