Step-by-step explanation:
5x - 7 = 13
5x = 13 + 7
5x = 20
x = 20 ÷ 4 = 5
10x - 14
10(5) - 14 = 50 - 14 = 36
Answer:
B: right
Step-by-step explanation:
9^2 + 12^2 = 15^2
(1, 8) and (7,1)
slope = (8-1)/(1-7) = -7/6
y = mx + b
b = y - mx
b = 8 - (-7/6)(1)
b = 8 + 7/6
b = 55/6
equation
y = -7/6(x) + 55/6
answer
<span>y=−7/6 x+55/6 </span>
Ratio of student to teacher = 17:3
Let the total number of students and faculty = x
Then
Number of students = 17X
Number of teachers =3X
So
17X+3X=740
20X = 740
X = 37
Then the number of students = 17*37
<span>
= 629</span>
Number of teachers = 3*37
<span>
=111 </span>
