Answer:500
Step-by-step explanation:So first u mutiply by 100 then divide by 90
Answer: 2/3x
Step-by-step explanation:
First, you need to simplify your original line to point slope formula. Dividing the whole thing by 2 to get y by itself leaves you with
y = 3/2x - 1/2
Any perpendicular line has the opposite slope to the line it is perpendicular to, so you flip the slope to get 2/3x
#1 is true. The term they have in common is y with an invisible coefficient in-front of the second y term
#2 has zero like terms. 15 has no variable, and the other terms have different variables.
#3 has two like terms, that’s 9 and 8 which add to equal 17. The answer is 3x + 17 aka D.
#4 has two like terms, the numbers with the variable ‘n’. 4n + 7n = 11n. Your answer is 11n + 12 aka D
X=number of females
47-x=number of males
# of males is 2*(number of females)-7:
47-x= 2x-7
add x to both sides:
47=3x-7
add 7 to both sides:
54=3x
divide both sides by 3:
x= 18 females
47-18= 29 males
