Answer:
x = -5
Step-by-step explanation:
-4(x+3)=8
(-4)(x)+(-4)(3)=8 (distribute)
-4x - 12 = 8
-4x - 12 + 12 = 8 + 12
-4x = 20
-4x/-4 = 20/-4 =
x = -5

Answer:
⅑
Step-by-step explanation:
Let m represents number of males, and f represents number of females taking the maths course.
Given that number of males (m) taking the maths course is 8 times as much as number of females (f), total number of students taking the maths course (T).
Thus we can represent the information above with the following:
m = no. of males
f = no. of females
T = Total
m = 8f
T = m + f
Thus,
Total = 8f + f = 9f
==>The fraction of the course that are females = No. of females (f) ÷ Total no. of students (T)
= f/9f
Fraction of females in simplified form would be ⅑
Answer:
x - z = -36
Step-by-step explanation:
Given:
x + y y + z
---------- = 32 and ---------- = 50
2 2
These lead to x + y = 64 and y + z = 100
Subtracting the second equation from the first yields:
x + y = 64
-( y + z = 100)
------------------------
x - z = -36
