The number of students in 5th grade is 60, since 24% of 250 is 60.

Since 90 is 38% if 250, 38 is going to be the percent of all students in sixth grade.

20% of 250 is 50, so the percent of all students in seventh grade is 50.

Finally, 45 is 18% of 250, so 18 percent of all students are in eight grade.

Hope this helped :)

Answer:60,38%,50,18%

Step-by-step explanation:

For 5th graders you have to change the 24% into a decimal as 0.24 then times 250

The second one you have to divide 95 by 250 and it will give you your answer just do the same with each question if their is percent you multiply and if their is numbers of students you divide by 250

The three angles of a triangular flag are x, twice the complement of x, and one-half the supplement of x
Angelina_Jolie [31]
Let x be the first angle
y be the second angle
z be the third angle.

for the second angle, complementary angles are angles sum are 90 degrees
y = 2 ( 90 - x )
y = 180 - 2x
2x + y = 180
for the third angle, supplementary angles are angles sum are 180 degrees
z = 0.5( 180 - x )
z = 90 - 0.5x
0.5x + z = 90

then the sum of a triangle is 180
x + y + z = 180
so x = 60
y = 60
z = 60

When graphing inequalities on the number line, which of the following statements are true? Select all that apply.
Softa [21]

Answer:

The correct options are;

1) "Greater/Less than or equal to" means the circle on the number will be SOLID

2)"Greater/Less than" means the circle on the number will be open

3) If It is "greater than", the line will be colored to the RIGHT of the number & if it is "less than", the line will be colored to the LEFT of the number line

Step-by-step explanation:

When a linear inequality is graphed on a number line, and the value of the inequality is "less than" or "greater than" the limit displayed on the number line, the limit of the inequality is indicated by an open

When the the limiting value of the inequality is specified as "less than or equal to" or "greater than or equal to" the value displayed on the number line as a SOLID circle.

The region where the inequality is valued on the number line is the colored region.

Find a solution to the following system of equations. –2x + y = –3 –x + 2y = 3
kvv77 [185]
-2x + y = -3.....multiply by -2
-x + 2y = 3
-----------------
4x - 2y = 6 (result of multiplying by -2) 
-x + 2y = 3
----------------add
3x = 9
x = 9/3
x = 3

-2x + y = -3
-2(3) + y = -3
-6 + y = -3
y = -3 + 6
y = 3

solution is (3,3)
