Answer:
x= 6
Step-by-step explanation:
\(12x +4 = 10x+16 \\\)
You will subtract 10x from 12x and get 2x
\(2x + 4 = 16\)
Subtract 4 from 16 to get 12
\(2x = 12\)
You will then divide both sides by 2
\(\frac{2x}{2}\) = \(\frac{12}{2}\)
x= 6
The second one is hard to read but since ∠3 is 54° you should just start from there
Hope this helps
Answer:
x = 6
Step-by-step explanation:
The Answer for the first figure:
m<5 and m<7 are equal, since they are corresponding angles. So, that means;
m<5 = m<7
12x + 4 = 10x + 16
12x - 10x = 16 - 4
2x = 12
x = 6 (when both divided by 2)
What is fl oz to gallon?
A gallon equals 4 quarts, 8 pints, or 128 fluid ounces.
Ounces to Gallons:Say a farmer in the US measures his cows' milk production by the ounce but sells it by the gallon. If the farmer collected 19,200 ounces of milk in a week, how many gallons of milk will he be able to sell?
The most important thing to remember about changing ounces to gallons is that there are 128 fluid ounces in every gallon.
Another way to think of it is for every gallon, you have 128 ounces. Let's use x to represent the number of ounces and y to represent the number of gallons.
x ounces / 128 = y gallons
Notice that this formula divides the number of ounces into groups of 128 to determine the number of gallons.
Remember the formula for finding how many fluid ounces are in a gallon:
x ounces / 128 = y gallons

A car travels 60mph for the first part of a trip abd then 80mph for the remainder of the trip which was twice as long as the first part of the trip. If the person drove a total of 330 miles, how much time was spent on each part of the trip? (please include a table of how you got the answer)
Therefore, the time spent traveling at 60mph is 1.5 hours, and the time spent traveling at 80mph is 2(1.5) = 3 hours.
Time spent traveling at 60mph = 1.5 hours
Time spent traveling at 80mph = 3 hours
How can you find distance in math?To calculate the distance between two locations, use the distance formula, a Pythagorean theorem application. The Pythagorean Theorem can be rewritten as d=((x 2-x 1)2+(y 2-y 1)2) to get the distance between any two points.
Let's denote the time spent traveling at 60mph as "t", then the time spent traveling at 80mph is "2t" because the second part of the trip is twice as long as the first part.
We can use the formula:
distance = speed x time
To calculate the distance traveled in each part of the trip, then we can set up the following equations:
distance traveled at 60mph = 60t
distance traveled at 80mph = 80(2t) = 160t
The total distance traveled is given as 330 miles, so we can set up the equation:
60t + 160t = 330
220t = 330
t = 1.5 hours
Therefore, the time spent traveling at 60mph is 1.5 hours, and the time spent traveling at 80mph is 2(1.5) = 3 hours.
Time spent traveling at 60mph = 1.5 hours
Time spent traveling at 80mph = 3 hours

which expression fails to compute the area of a triangle having base b and height h (area is one-half base time height)?a.(1.0 / 2.0 ) * b * hb.(1 / 2) * b * hc.(b * h) / 2.0d.0.5 * b * h
The expression that fails to compute the area of a triangle correctly is option b: (1 / 2) * b * h.
The correct formula to compute the area of a triangle is one-half times the base multiplied by the height, which can be written as (1/2) * b * h. Option a, c, and d correctly represent this formula. However, option b is incorrect because it uses integer division instead of decimal division.
In option b, (1 / 2) is computed using integer division, which results in truncating the decimal part. Therefore, (1 / 2) evaluates to 0 instead of 0.5. As a result, the expression (1 / 2) * b * h would yield incorrect and significantly smaller results than the actual area of the triangle.
To accurately calculate the area of a triangle using this formula, it is essential to use decimal division or explicitly represent the fraction as a decimal. Options a, c, and d correctly account for this by using either 1.0/2.0 or 0.5, ensuring the proper calculation of the area.

You have two pieces of rope. One piece is of rope is 98 feet and the other is 56 feet. You need to cut the rope into equal lengths with non left over. What is the greatest possible lenth you can cut the rope so all peices will be the same
Answer:
14 feet
Step-by-step explanation:
We solve the above question by using the Greatest Common Factor method
We find the factors of 56 and 98
The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56
The factors of 98 are: 1, 2, 7, 14, 49, 98
Then the greatest common factor is 14.
Therefore, the greatest possible length you can cut the rope so all pieces will be the same is 14 feet
Find f[g(x)] and g[f(x)] for the given functions. 3 f(x) = -x³ +3, g(x) = 4x+7 (Simplify your answer. Do not factor.) (Simplify your answer. Do not factor.) f[g(x)] = g[f(x)] =
The value of f[g(x)] is - 64x³ - 336x² - 588x - 340 and the value of g[f(x)] is -4x³ + 19
The functions are as follows; f(x) = -x³ +3 and g(x) = 4x+7
The value of f[g(x)] is obtained by replacing every x in f(x) with the value of g(x) as given below
f[g(x)] = f(4x + 7) = - (4x + 7)³ + 3
When we expand (4x + 7)³, it gives us 64x³ + 336x² + 588x + 343
Then
f[g(x)] = - 64x³ - 336x² - 588x - 340
Similarly, g[f(x)] is obtained by replacing every x in g(x) with the value of f(x) as shown below;
g[f(x)] = g(-x³ + 3) = 4(-x³ + 3) + 7g
[f(x)] = -4x³ + 19
Therefore,
f[g(x)] = - 64x³ - 336x² - 588x - 340

intercepts: (0, 5/2) or (-5, 0)arbitrary point: (7, 6)Step-by-step explanation:
You want two methods of choosing points on the line with slope 1/2 through A(-1, 2).
InterceptsWriting the equation in standard form, we can find the x- and y-intercepts. To get there, we can start from point-slope form:
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -2 = 1/2(x -(-1)) . . . . . using given slope and point
2y -4 = x +1 . . . . . . . . . . multiply by 2
x -2y = -5 . . . . . . . . . . . . add -1 -2y
Setting x=0 tells us the y-intercept is ...
0 -2y = -5
y = -5/-2 = 5/2
So, the y-intercept is (0, 5/2).
Setting y=0 tells us the x-intercept is ...
x -2(0) = -5
x = -5
So, the x-intercept is (-5, 0).
Arbitrary pointIt will be convenient to choose an arbitrary y-value to find another point on the line. We can pick y = 6, for example, Then the corresponding x-value is ...
x -2y = -5
x = -5 +2y = -5 +2(6) = 7
Another point on the line is (7, 6).
__
Additional comment
If we were to choose an arbitrary value for x, we would want it to be odd, so the corresponding y-value would be an integer. We chose to pick an arbitrary value of y so we didn't have to worry about how to make the x-value an integer.

isosceles triangle abc has a perimeter of 96 centimeters. the base of the triangle is line segment a c and measures 24 centimeters.
The measure of the line segment AB is 36cm .
In the question ,
it is given that ,
The triangle ABC is a isosceles triangle ,
that means side AB = side BC ,
and the length of base AC = 24 cm .
given the perimeter of the triangle is 96 cm .
So ,
AB + BC + AC = 96
AB + AB + AC = 96 .....because AB = BC
2AB + AC = 96
Substituting the value of AC = 24 cm
2AB + 24 = 96
Subtracting 24 from both the sides , we get
2AB = 96 - 24
2AB = 72
Dividing both sides by 2 ,
we get ,
AB = 72/2 = 36 .
Therefore , The measure of the line segment AB is 36cm .
