Answer:
x = 13
Step-by-step explanation:
A linear pair of angles sum to 180° , then
2x + 9 + 10x + 15 = 180 , that is
12x + 24 = 180 ( subtract 24 from both sides )
12x = 156 ( divide both sides by 12 )
x = 13
Can someone help me?
Answer:
x = 5
Step-by-step explanation:
If the lines containing points A, B, C, D are parallel, then those two angles are equal because they would be corresponding angles. Therefore, you would set up this equation:
25x - 17 = 20x + 8
Subtract 20x from both sides
5x - 17 = 8
Add 17 to both sides
5x = 25
Divide both sides by 5
x = 5
The first container of milk contains twice as much milk as the second container and the 3 gallons of milk from the first container, the first container has 4.5 times as much milk as the second. How many gallons of milk were in each container originally?
Answer:
There are [tex]4.58[/tex] gallons of milk in each container.
Step-by-step explanation:
Given:
[tex]1[/tex]st container has [tex]2x[/tex] gal.
[tex]2[/tex]nd container has [tex]x[/tex] gal.
To calculate the number of gallons
[tex]2x - 3 = x-2 + 4.5(x-2)[/tex]
[tex]2x - 3 = 5.5x - 11[/tex]
[tex]-3.5x = -8[/tex]
[tex]x = 2.29[/tex] gal.
[tex]2x = 4.58[/tex] gal.
Hence, there are [tex]4.58[/tex] gallons of milk in each container originally.

https://brainly.com/question/237650tom is 2 kg heavier than harry, who is 3 kg heavier than ben. when they add up all their weights, it comes to 65 kg. how many kg does harry weigh?
Answer:
Step-by-step explanation:
Let Harry = x
Tom = harry + 2
Tom = x + 2
Ben + 3 = harry
harry - 3 = ben
x - 3 = ben
Tom + harry + Ben = 65
x + 2 + x + x - 3 = 65
3x - 1 = 65 Add 1 to both sides
3x = 65 + 1
3x = 66 Divide by 3
x = 66/3
x = 22
So harry = 22 kg

Find the slope of the line through each pair of points (20,-16),(19-16)
Answer:
Undefined slope.
Step-by-step explanation:
The formula should be y2 - y1 over x2 - x1
Points ( 20,-16 ) and ( 19, -16 )
So ( -16 - ( -16 ) ) over ( 19 - 20 )
0 over -1
The slope is 0. Undefined.
Answer:
Slope = 0
This line is not sloped. It moves flat relative to the x axis.
Step-by-step explanation:
Slope = (y2 - y1) / (x2 - x1)
= (-16 - (-16)) / (19 - 20)
= (-16 + 16) / (-1)
= 0 / -1
= 0

Answer:

if 4 is added to greater number the sum is thrice the smaller number find the number
Sentence is not clear, but based on what i understood :
The following sum : "4 added to a greater number" can be written as follow. Let x be that greater number (x > 4) :
"4 + x"
Then this Sum's value, is thrice the smaller number : 3 × 4 = 12.
Finally, we need to solve this equation :
4 + x = 3 × 4
4 + x = 12
We subtract 4 on both sides of the equation :
4 + x - 4 = 12 - 4
x = 8
So this number x, is equal to 8.

Using the Triangle Sum Theorem. Determine the angle measure
of <1.
38
31
(78 and 31 degrees)
Answer:
71 degrees
Step-by-step explanation:
Hi there!
The sum of the interior angles of a triangle is always 180 degrees.
Knowing this, to solve for the measure of angle 1, subtract 78 and 31 degrees from 180:
180-78-31
= 71
Therefore, angle 1 measure 71 degrees.

Sarah has saved $150. She wants to double the amount she saves each month. As an incentive, Sarah’s grandma says if she saves that amount, she will give her an additional $50 each month. What are the recursive formula and first term for Sarah’s saving’s?
Answer:
A₁ = $150.
Step-by-step explanation:
We know that:
Sarah has saved $150 at the moment.
She wants to double the amount that she saves each month, so the next month she needs to save 2*$150 = $300
And if she saves the $300, then her grandma will give her another $50.
Then, if the previous month Sarah saved A, then the next month she will get the double of A plus $50, which is:
2*A + $50
Then the recursive relation is just:
Where Aₙ is the amount that she saves in the n-th month, and the first term of the sequence is the initial amount that she saved, so we have:
A₁ = $150.

Un terreno tiene las siguientes dimensiones 52 m x 44 m. Una persona trota por la orilla del terreno y todos los días recorre 4.5 vueltas, partiendo de un vértice del rectángulo, si todo el recorrido lo hace en 1.47 minutos ¿Cuál es la magnitud de la velocidad (m/s) que realizó?
Podemos definir la magnitud de la velocidad como el cociente entre la distancia total recorrida y el tiempo que tomo recorrerla.
Encontraremos que la magnitud de la velocidad es 9.8 m/s.
En este caso, tenemos un terreno rectangular de 52m por 44m.
Recordamos que el perimetro de un rectangulo de largo L y ancho A está dado por:
P = 2*(L + A)
En este caso, el perimetro será:
P = 2*( 52m + 44m) = 192m
Si la persona recorre este perimetro 4.5 veces, entonces la distancia total que recorre es 192 metros por 4.5:
distancia = 4.5*192m = 864m
Y sabemos que la recorre en 1.47 minutos.
Notar que queremos la magnitud de la velocidad en metros sobre segundo, por lo que debemos reescribir este tiempo en segundos.
1 minuto = 60 segundos
Entonces:
1.47 minutos = (1.47)*60 segundos = 88.2 segundos.
Finalmente, la magnitud de la velocidad será:
V = (864m)/(88.2s) = 9.8 m/s
