Answer:
x=6
Step-by-step explanation:
i used an app called math-way hope this helps.
Answer:
x = 6
Step-by-step explanation:
3(x-4) + 3 = 9
3x - 12 + 3 = 9
3x - 9 = 9
3x = 9 + 9
3x = 18
x = 6
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
Can someone please help me answer this question asap thank you
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.
Function 2 has the greater rate of change

12. One dekameter is equal to 1,000
centimeters. If Howard's driveway
measures 1.75 dekameters long, how
many centimeters long is the driveway?
Explain your answer.
Answer quick PLZZ no website
Answer:
the number of centimeters is 1,750
Step-by-step explanation:
The computation of the number of centimeters is shown below;
Given that
1 dekameter = 1000 centimeter
And, there are 1.75 dekameters
So, the number of centimeter is
= 1000 × 1.75
= 1,750 centimeter long
Hence, the number of centimeters is 1,750
Therefore the same would be considered and relevant too

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
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

What is the greatest common factor of 5xy and 20x
Answer:
5x
Step-by-step explanation:
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.

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°.

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.

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°
