Answer:
"statement 1: The number of boys at the school is 
of the number of girls." is true.
Step-by-step explanation:
Given:
Ratio of Number of boys to the number of girls = 4 : 5
Total number of students = 270
To find:
Number of boys in terms of number of girls = ?
Solution:
As per given statement,
Let, Number of boys = 
Let, Number of girls = 
Total number of students = Number of boys + Number of girls = 270
Therefore, number of boys = 4 
30 = 120
And, number of girls = 5 30 = 150
As per Statement 1:
Finding of the number of girls:
= Number of boys.
Finding 
of the total number of students:
= Number of boys.
Number of boys is equal to of total number of students.
So, "statement 1: The number of boys at the school is of the number of girls." is true.
The partial factorization of 2 x - 3 x - 10 is modeled with algebra tiles is that you will need 2 x tiles and 4 negative 1 tiles and 3 positive 1 tiles.
Answer:
about 137 degrees
Step-by-step explanation:
see attached picture
(3)(-5x+y=-3)
(5)(3x-8y=24)
-15x+3y=-9
15x-40y=120
3y=-9
-40y=120
-37y=111
Divide both sides by -37
y=-3
To solve for x. Choose one equation from the given and plug what you get in Y.
I'll choose, -5x+y=-3
So, -5x+(-3)=-3
-5x=0
Divide both sides by -5
x=0/-5
Hope, this helps.
