Answer:
x = 8
Step-by-step explanation:
Assuming the figure is a parallelogram, the diagonals bisect each other. That means ...
3x -11 = x +5
2x = 16 . . . . . . . add 11-x to both sides
x = 8 . . . . . . divide by 2
Answer:
the answer is x=8

L U C K luck is parallelogram with ∠C=68° and ∠LUK=42° find: 1.
m∠ CUK 2. m∠ K
Answer:
1. m∠CUK = 70°
2. m∠K = 112°
Step-by-step explanation:
1. The given parameters of the parallelogram LUCK are;
∠C = 68°
∠LUK = 42°
From the diagram of parallelogram LUCK obtained from an online source, we have;
Given that LUCK = A parallelogram, we have;
The same side interior angles ∠C and ∠U are supplementary angles
Therefore;
∠C + ∠U = 180°
∠U = 180° - ∠ C
∴ ∠U = 180° - 68° = 112°
∠U = 112°
By angle addition property, ∠U = ∠LUK + ∠CUK
∴ m∠CUK = ∠U - ∠LUK
By plugging in the value of ∠LUK = 42°, and ∠U = 112°, we have;
m∠CUK = ∠U - ∠LUK = 112° - 42° = 70°
m∠CUK = 70°
2. By angle addition property, we have;
∠K = ∠LKU + ∠CKU
∠LKU and ∠CUK are alternate interior angles
∴ ∠LKU = ∠CUK = 70°
Similarly, ∠CKU and ∠LUK are alternate interior angles
∠CKU = ∠LUK = 42°
m∠K = ∠LKU + ∠CKU = 70° + 42° = 112°
m∠K = 112°.
which is the solution set for the quadratic equation x^2-9=0
===================================================
Explanation:
We could add 9 to both sides, and then apply the square root to both sides. Don't forget about the plus minus
x^2 - 9 = 0
x^2 = 9
x = sqrt(9) or x = -sqrt(9)
x = 3 or x = -3
To check these answers, you replace x with those values we found. I'll show you how to check x = 3
x^2 - 9 = 0
(3)^2 - 9 = 0
9 - 9 = 0
0 = 0
So that confirms x = 3. The confirmation for x = -3 is nearly the same. Keep in mind that (-3)^2 = (-3)(-3) = 9. You'll be squaring the negative as well.
------------------
Another method you could do is to use the difference of squares rule
x^2 - 9 = 0
x^2 - 3^2 = 0
(x - 3)(x + 3) = 0
Now apply the zero product property. This effectively means you set each factor equal to zero and solve for x
x-3 = 0 or x+3 = 0
x = 3 or x = -3
We end up with the same solution set.
Yet another method you could use is the quadratic formula, but that may be overkill. It's still good practice to do.
Graphing is a visual way to find the answers. You'll graph y = x^2 - 9 and look to see where the curve crosses or touches the horizontal x axis.

Use the arithmetic series formula to calculate the sum of the first 15 terms of the sequence: a n =5n+3
Answer:
S₁₅ = 645
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Using the nth term formula [tex]a_{n}[/tex] = 5n + 3 , then
a₁ = 5(1) + 3 = 5 + 3 = 8
a₂ = 5(2) + 3 = 10 + 3 = 13 , then
d = a₂ - a₁ = 13 - 8 = 5
Thus
S₁₅ = [tex]\frac{15}{2}[/tex] [ (2 × 8) + (14 × 5) ]
= 7.5( 16 + 70)
= 7.5 × 86
= 645
One Baseball Weigh 14.2 g how many grams would 100 baseballs weigh
Answer:
1,420 grams per 100 baseballs
Step-by-step explanation:
Set up an equation:
Variable x = grams per 100 baseballs
1/14.2 = 100/x
Cross multiply
1 × x = 14.2 × 100
1x = 1420
x = 1420

A sample of nitrogen gas has a pressure of 6.58 kPa at 539K. If the volume does not
change, what will the pressure be at -62C.
Answer:
2.575844
Step-by-step explanation:
This is a simple change of temp problem, from 539K to -62C but to start you have to change the C to K, which is simply adding 273 to the -62 so 211K.
Now you take P1/T1 = P2/T2 so,
6.58 = x
539 = 211
now cross multiply and divide, 211 x 6.58 then divide by 539.
this will give you your answer

At the craft store, Kim bought a bag of marbles. In the bag there were 20 blue marbles and 30 green marbles. What percent of the marbles were green?
Answer:
60%
Step-by-step explanation:
percent of green marbles = (total number of green marbles / total number of marbles in the bag) x 100
total number of marbles in the bag = 30 + 20 = 50
30 / 50 x 100 = 60%
Answer:
60%

lines m and p are cut by the transversal n. determine the value of x. write the measures of the six angles. show all work
x = 36
Step-by-step explanation:
The angles 4x and x are supplementary, meaning they add up to 180; therefore we have
[tex]4x + x = 180[/tex]
[tex]5x = 180[/tex]
dividing both sides by 5 gives
[tex]x = 36[/tex]
the measure of angle x is 36 and that of 4x is 4 * 36 = 144
The angle opposite to 4x also measures 144 and the one opposite to x is 36.
Answer:
x° + 4x° = 180°
5x° = 180°
x° = 180°/5
x° = 36°

The measures of the three angles of a
triangle are given by 2x + 6, x, and 3x.
What is the measure of the largest angle?
Answer:
[tex]\boxed {\boxed {\sf 87 \ degrees}}[/tex]
Step-by-step explanation:
The angles in a triangle must add to 180 degrees.
We are given three angles: 2x+6, x, and 3x. Their sum must be 180, so we can create an equation.
[tex]2x+6+x+3x=180[/tex]
Combine like terms (all terms with an x) on the left side.
[tex](2x+x+3x)+6=180[/tex]
[tex]6x+6=180[/tex]
Now solve for x by isolating the variable.
6 is being added and the inverse of addition is subtraction. Subtract 6 from both sides.
[tex]6x+6-6=180-6\\6x=174\\[/tex]
x is being multiplied by 6. The inverse of multiplication is division. Divide both sides by 6.
[tex]6x/6=174/6 \\x=29[/tex]
Substitute 29 for x in the angle measures.
2x+6= 2(29)+6=58+6=64x=29 3x= 3(29)=87The largest angle is 87 degrees.

Which function has the greater rate of change? Function 1: y = -1/2x +5
or Function 2: y = -3/4x - 4
I’ll give brainliest
The rate of change is the slope. The slope is the number in front of the x
Function 1 rate of change is -1/2
Function 2 rate of change is -3/4
The greater rate of change would be the steepest slope.
