Answer:
195 students are left-handed
Step-by-step explanation:
Here, we want to calculate the total number of students who are left-handed
Let the total number of students in the school be x
The total ratio is 8 + 3 = 11
8/11 * x = 520
8x = 11 * 520
x = (11 * 520)/8
x = 715 students
So the number of students who are left handed will be;
Total - number of right-handed students
That would be;
715-520 = 195

A public parking garage charges $5, plus an additional $2 per hour.
Choose the graph of the line.
Answer:
2nd one
Step-by-step explanation:
Graph-2 is correct line that represents the parking charge of the public garage.
What is a linear equation?A linear equation is an equation where the variable has the highest degree of 1.
Given, a public parking garage charges $5, plus an additional $2 per hour.
For 1 hour, the total cost will be = $(5 + 2 × 1) = $7.
For 2 hours, the total cost will be = $(5 + 2 × 2) = $9.
For 3 hours, the total cost will be = $(5 + 2 × 3) = $11.
For 4 hours, the total cost will be = $(5 + 2 × 4) = $13.
For 5 hours, the total cost will be = $(5 + 2 × 5) = $15.
Here, the increase in parking cost is in the form of linear equation and it increases $2 with the increase in every hour.
Therefore, graph-2 represents the actual line of cost of the parking charge and time.

3. The sum of the two numbers is5/9
If one of the numbers is
1/3 find the other
Step-by-step explanation:
let the one number be X.
and
second one 1/3
then
1/3 +X = 5/9
X = 5/9-1/3
X =( 5-3) /9
X = 2/9 Ans
Answer:
The other number will be 2/9.
Step-by-step explanation:
Let the second fraction be x :
[tex] \frac{1}{3} + x = \frac{5}{9} [/tex]
[tex]x = \frac{5}{9} - \frac{1}{3} [/tex]
[tex]x = \frac{5}{9} - \frac{3}{9} [/tex]
[tex]x = \frac{2}{9} [/tex]

Antonio, Lucas y Darío compraron un refresco de 5/2 (2litros y 1/2) que piensan repartir en partes iguales. a) ¿Qué fracción de litro le corresponde a cada uno? b) Una vez repartido el refresco llego Benjamín a quien van a convidarle. ¿Cuánto debe convidarle cada uno para que los cuatro tengan la misma cantidad de refresco?
Answer:
a) A Antonio, Lucas y Darío le corresponde cada uno [tex]\frac{5}{6}[/tex] litros.
b) Antonio, Lucas y Benjamín deben convidar cada uno [tex]\frac{5}{24}[/tex] litros.
Step-by-step explanation:
a) Antonio, Lucas y Darío compraron un refresco, el cual reparten en tres partes iguales. Por tanto, la fracción de litro para cada persona es la capacidad del refresco dividido por el número de personas. Es decir:
[tex]x = \frac{\frac{5}{2}\,L }{3}[/tex]
[tex]x = \frac{5}{6}\,L[/tex]
A Antonio, Lucas y Darío le corresponde cada uno [tex]\frac{5}{6}[/tex] litros.
b) En primer lugar calculamos la fracción correspondiente a cuatro personas:
[tex]x = \frac{\frac{5}{2}\,L }{4}[/tex]
[tex]x = \frac{5}{8}\,L[/tex]
Ahora, procedemos a calcular la diferencia entre el escenario calculado en a) y el resultado anterior:
[tex]\Delta x = \frac{5}{6}\,L-\frac{5}{8}\,L[/tex]
[tex]\Delta x = \frac{40-30}{48} \,L[/tex]
[tex]\Delta x = \frac{10}{48}\,L[/tex]
[tex]\Delta x = \frac{5}{24}\,L[/tex]
Este resultado corresponde a la fracción que Antonio, Lucas y Darío deben convidar cada uno a Benjamín. Entonces, Antonio, Lucas y Benjamín deben convidar cada uno [tex]\frac{5}{24}[/tex] litros.

help me find the perimeter plzzz!
Answer:
2m-4
Step-by-step explanation:
double both of them and just simplify
the first one will become (6m-12) and the second will become (-4m+8)
subtract 6m and -4m so it's 2m
subtract -12 and 8 so it's -4
so the answer is 2m-4
Answer:
B. 2m - 4
Step-by-step explanation:
When simplifying the expression (3m - 6) + (3m - 6) + (-2m + 4 ) + (-2m + 4) while trying to find the perimeter, you will find your answer to be 2m - 4.

Select the equation that contains the point (3,6) and in which the slope equals 1
Answer:
I think it would be y + 6 = x + 3
Step-by-step explanation:
Because they both have to be positive because the points are positive. Also the slope has to be 1 so x cannot have a number with it or else it changes the value.
I would say it is 1)y + 6 = x + 3 but I am not no genius

solve (2x-10)=(65-x) show your work plz!
Answer: x=25
Step-by-step explanation:
Simplifying
(2x + -10) = (65 + -1x)
Reorder the terms:
(-10 + 2x) = (65 + -1x)
Remove parenthesis around (-10 + 2x)
-10 + 2x = (65 + -1x)
Remove parenthesis around (65 + -1x)
-10 + 2x = 65 + -1x
Solving
-10 + 2x = 65 + -1x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'x' to each side of the equation.
-10 + 2x + x = 65 + -1x + x
Combine like terms: 2x + x = 3x
-10 + 3x = 65 + -1x + x
Combine like terms: -1x + x = 0
-10 + 3x = 65 + 0
-10 + 3x = 65
Add '10' to each side of the equation.
-10 + 10 + 3x = 65 + 10
Combine like terms: -10 + 10 = 0
0 + 3x = 65 + 10
3x = 65 + 10
Combine like terms: 65 + 10 = 75
3x = 75
Divide each side by '3'.
x = 25
Simplifying
x = 25

Tobin is solving the equation 3 (x minus 1.25) = 11.25. His work is shown below.
3 (x minus 1.25) = 11.25. 3 x minus 3.75 = 11.25. 3 x minus 3.75 + 3.75 = 11.25 + 3.75. 3 x = 15. 3 x times 3 = 45 times 3. x = 135.

Write an equation in standard form of the line that passes through the following
points, where a ≠0 and b ≠0.
Answer:
The equation =3 is equivalent to = 0 +3. From this form, we know the line has slope =0.
Step-by-step explanation:
Answer:
ax + by = c
Step-by-step explanation:
The standard form of the line is
ax + by = c; where a, b and c are numbers
Also a and b are coefficients are not zero so there are x and y terms.
It took everly 55 minutes to run a 10-kilometer race last weekend. If you know that 1 kilometer equals 0.621 mile, how many mintues did it take everly to run 1 mile during the race?
Answer:
8.9 minutes
Step-by-step explanation:
Converting Everly Kilometer race to miles
1 km = 0.621 miles
10 km =
10 × 0.621 miles
= 6.21 miles
Hence,
6.21 miles = 55 minutes
1 mile = x minutes
Cross Multiply
6.21 × x = 55 × 1
x = 55 minutes/6.21
x = 8.8566827697 minutes
Approximately = 8.9 minutes
