Answer:
∠A = 100
∠B = 50
∠C = 30
Step-by-step explanation:
Sum of all angles of triangle = 180
∠A + ∠B + ∠C = 180
2x +x + x - 20 = 180 {Combine like terms}
4x - 20 = 180
Add 20 to both sides
4x = 180 + 20
4x = 200
Divide both sides by 4
x = 200/4
x = 50
∠A = 2x = 2*50 = 100
∠B = x = 50
∠C = x - 20 = 50 - 20 = 30

Cual es la constante de proporcionalidad de 1/2 ?
Answer:
Therefore, the relationship given in the table is proportional. When we look at the above table when x gets increased, y also gets increased, so it is direct proportion. Substitute 2 for x and 1 for y. So, the constant of proportionality is 1/2.

members of a softball team raised 1405.25 to go to a tournament. they rnted a bus for 822.50 and budgeted 27.75 per each players . write and solve an equation which can be used to determine x , the number of players the team can bring to the tournament
Creating an expression for the scenario, the Number of players that can be brought to the tournament is 21.
Given the Parameters :
Total amount raised = 1405.25Bus rent = 822.50Amount per player = 27.75We could represent the expression to calculate the number of players thus :
Total amount raised = (Bus rent + (amount per player × number of Players))
1405.25 = 822.50 + 27.75x
1405.25 - 822.50 = 27.75x
582.75 = 27.75x
x = (582.75÷27.75)
x = 21 players
Therefore, the Number of players would be 21.

x-1/2=x-2/3 solve the proportion
Answer:
0 = − 1 /6
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
To find the value of x, we first find the fraction that is equivalent to 1/3 that has a denominator of 12.
Multiplying or dividing the numerator and denominator of
a fraction by the same number will give us an equivalent fraction.
So if we multiply both the numerator and denominator of
the first fraction by 4, we can see that 1/3 = 4/12.
So the value of x must be 4.

rewrite the equation in standard form y - 6 = -1/2 (x-5)
Standard Form: Ax + By = C
---A cannot be negative, nor can it be a decimal or fraction
y - 6 = -1/2(x - 5)
Distribute the -1/2
y - 6 = -1/2x + 5/2
Add -1/2x to both sides
1/2x + y - 6 = 5/2
Add 6 to both sides
1/2x + y = 17/2
Multiply everything by 2 to get rid of the fractions
x + 2y = 17

[tex]Simplify: \frac{ {x}^{a + b} . {x}^{b + c} {x}^{c + a} }{ {x}^{a}. {x}^{b} . {x}^{c} } \\ [/tex]
Need help please.
Step-by-step explanation:
[tex] \bf \underline{Solution-} \\ [/tex]
We have to simplify the given expression.
[tex] \rm = \dfrac{ {x}^{a + b} \cdot {x}^{b + c} \cdot {x}^{c + a} }{ {x}^{a} \cdot {x}^{b} \cdot {x}^{c} } [/tex]
We know that:
[tex] \rm \longmapsto {x}^{a} \times {x}^{b} = {x}^{a + b} [/tex]
[tex] \rm \longmapsto \dfrac{ {x}^{a} }{ {x}^{b} } = {x}^{a - b} [/tex]
Therefore, we get:
[tex] \rm = \dfrac{ {x}^{(a + b) + (b + c) + (c + a)}}{ {x}^{a + b + c} } [/tex]
[tex] \rm = \dfrac{ {x}^{2(a + b+ c)}}{ {x}^{a + b + c} } [/tex]
[tex] \rm = {x}^{2(a + b+ c) - (a + b + c)}[/tex]
[tex] \rm = {x}^{a + b + c}[/tex]

To isolate x, we will first subtract 0.8 from both sides.
0.6x + 0.8 = 1.4
-0.8 -0.8
0.6x = 0.6
Now all we have to do is divide both sides by 0.6, because it is the number besides x.
0.6x/0.6 = 0.6/0.6
x = 1
So you get the answer of x = 1.
Below is a recipe for chocolate chip cookies. The recipe makes 27 cookies. How many teaspoons of vanilla extract do you need to make 24 cookies? Round to the nearest hundredth if needed.
Answer: 1.78 teaspoons
Step-by-step explanation:
The recipe says: 27 cookies/2 teaspoons Vanilla extract. Let's abbreviation this conversion factor as (27/2)C/V, where C is cookie and V is 1 teaspoon vanilla extract. We have both 13.5C/V and 1V/13.5C as conversion factors. 13.5 cookies is equivalent to 1 teaspoon vanilla, or 1 teaspoon vanilla is equivalent to 13.5 cookies. We can multiply ofr divide either of these factors, since they are both equivalent to 1, and you can mukltiply or divide anything by 1 without changing it's accuracy. The atual numbers will change, but the units will also change, making it a valid result.
We want 24 cookies. Use one of the conversion factors to find the teaspoons vanilla extract required:
1) We can divide by (27C/2V)
24C/((27C/2V) = 1.78 teaspoons
or
2) we can multiply by (1V/13.5C)
24C*(1V/13.5C) = 1.78 teaspoons

add 3 to x so

(2 x 3) + (3 x 4) =
Answer:
18
Step-by-step explanation:
To answer, you want to follow PEMDAS:
P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
So, the first step is parentheses, therefore we do whatever is inside the parentheses, and that is multiplying:
(2 * 3) + (3 * 4) =
6 + 12
Now, because there are no exponents, we cannot multiply anymore, and we cannot divide, we can add:
6 + 12 =
18
And that is our final answer!

a line with the slope of -3 passes through (-8, p) and (2, 3p). Find the value of p
Answer:
To find the Slope: Slope Formula: m = y2 −y1 x2 −x1. Given points: P (6,2) and S(3,1) will be our (x1,y1) and (x2,y2) respectively. Hence x1 = 6,y1 = 2,x2 = 3,y2 = 1. Slope(m) = 1 −2 3 −6. ⇒ −1 −3 = 1 3.
Step-by-step explanation:
Answer:
p = -15
Step-by-step explanation:
[tex]-3=\frac{3p-p}{2-(-8)} =\frac{2p}{10}[/tex]
[tex]\frac{2p}{10} =-3[/tex]
[tex]2p=-3(10)[/tex]
[tex]p=\frac{-30}{2}[/tex]
[tex]p=-15[/tex]
[tex]m=\frac{-45-(-15)}{2-(-8)} =\frac{-45+15}{2+8} =\frac{-30}{10} =-3[/tex]
