2x - y = 3
x = -2y - 1
Answer:
x = 1, y = - 1Step-by-step explanation:
2x - y = 3
x = -2y - 1
2x - y = 3
2(-2y - 1) - y = 3
-4y - 2 - y = 3 {add 2 to both sides}
- 5y = 5 {divide both sides by (-5)}
y = -1
x = -2y - 1 = -2(-1) - 1 = 2 - 1 = 1

Answer:
use division
Step-by-step explanation:
Answer:
525
Step-by-step explanation:
first we need to work out the percentage of the children who attended to to do this we need to add 47% with 32% which is 79%. Then you need to take away 79% from 100% which is 21%. After that you now know that 21% is the children who attended but you wanted to know how many children so to work this out you would find 21% of 2500 which would give you 525.

Answer:
D
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + 12² = 13²
a² + 144 = 169 ( subtract 144 from both sides )
a² = 25 ( take the square root of both sides )
a = [tex]\sqrt{25}[/tex] = 5 → D

tanya has 12 less votes than cynthia for class president. Write and solve a subtraction equation to find the number of votes for cynthia
Answer:
c - 12 = t
Step-by-step explanation:
c stands for cynthia and t stands for tanya
since tanya has 12 less votes than cynthia, you would subtract 12 from cynthia
Answer:
c-12=t
Step-by-step explanation:
Cynthia's number of votes for class president is unknown.
But, we know that Tanya has 12 less votes than her, so if you subtract Cynthia amount of votes by 12 you will get Tanya's.
Hope this helps! :)

Answer:
Angle SFE = 115 °
Step-by-step explanation:
GFS + SFE = GFE
26° + 114x+1 = 142x -1
28° + 114 x. = 142x
28°= 142x-114x
28° = 28x. Thus,x=1
=> Angle SFE = 114(1)+1= 115°

Todos los días por la mañana Alfonso maneja a una velocidad de 80 km/hr para llegar a su trabajo a tiempo realizando un tiempo de 42min de regreso por la tarde disminuye su velocidad a 65km/hr ¿cuanto tiempo tarda para llegar a casa
Usando proporciones, tiene-se que tardará 52 minutos para llegar a casa.
-----------------------------
Esta pregunta se resuelve por proporciones, usando una regla de tres. Considerando que la velocidad y el tiempo son inversamente proporcionales, a medida que uno aumenta y el otro disminuye, se aplica una regla inversa de tres, en la que la multiplicación está en la línea en lugar de cruzada.-----------------------------
80km/hr tiene un tiempo de 42 min. Qual el tiempo a una velocidad de 65 km/hr?80 km/hr - 42 min
65 km/hr - x min
Multiplicando las líneas:
[tex]65x = 80 \times 42[/tex]
[tex]x = \frac{80 \times 42}{65}[/tex]
[tex]x = 52[/tex]
Tardará 52 minutos para llegar a casa.

In a company, 60% of the workers are men If people work for the company who aren't men, how many workers are there in all? Use pencil and paper. Show two different ways that you can solve this problem.
Complete question :
In a company, 60% of the workers are men If 125 people work for the company who aren't men, how many workers are there in all? Use pencil and paper. Show two different ways that you can solve this problem.
Answer:
313
Step-by-step explanation:
Given that :
Percentage of workers who are men = 60%
Number of workers who aren't men = 125
Hence, percentage of workers who aren't men = (100% - 60%) = 40%
Thus;
40% of workers = 125
If ;
0.4 = 125
100% of the workers x
0.4 = 125
1 = x
Cross multiply
0.4x = 125
0.4x / 0.4 = 125 / 0.4
x = 312.5
Hence, total number of workers = 313
What is a equation of the line that passes through the point (−5,7) and is parallel to the line x+5y=10
Answer:
[tex]\displaystyle y = -\frac{1}{5} x +6[/tex]
Step-by-step explanation:
Equation of a LIne
The point-slope form of the equation of a line is:
y - k = m ( x - h )
Where m is the slope and (h,k) is a point through which the line passes.
We are required to find the equation of a line that passes through the point (-5,7) and is parallel to the line x+5y=10.
This information provides us the values of h=-5 and k=7. We now need to determine the value of the slope.
Two parallel lines have equal values for the slopes. The equation of the line
x + 5y = 10
Can be rearranged in such a way we can find its slope. Let's solve it for y:
5y = -x + 10
[tex]y = -\frac{1}{5}+2[/tex]
The slope of this line is -1/5 and that is the same value of the slope of our line, thus its equation is:
[tex]\displaystyle y - 7 = -\frac{1}{5} ( x + 5 )[/tex]
Adding 7:
[tex]\displaystyle y = -\frac{1}{5} ( x + 5 )+7[/tex]
Operating:
[tex]\displaystyle y = -\frac{1}{5} x + -\frac{1}{5}*5 +7[/tex]
[tex]\displaystyle y = -\frac{1}{5} x -1+7[/tex]
[tex]\boxed{\displaystyle y = -\frac{1}{5} x +6}[/tex]
Answer:
7=-1/5x+6 is the answer
