Answer:

90 couples or 180 ppl

Step-by-step explanation:

lets take "x" as the couples who remained at the party

we start out with 250:

250

but by the time it is 11pm, 70 people have left the party

since it is a couples party we need to divide by two to account for the couples

\frac{250-70}{2}=x

250-70=180

180/2=90

so 90 couples or 180 ppl

hope this helps

Relationship between the value of the given digits 6s in 660
expeople1 [14]
We have the given number = 660
Now, explain the relationship of 6s in the given number.
=> 6 = hundreds
=> 6 = tens
=> 0 = ones
This is also another form:
=> 6 = 600
=> 6 = 60,
now, notice that the first value of 6 in the leftmost side is 10 times higher than the next number 6.
=> 60 x 10 = 600.
Thus, 600 is 10 times greater than 60 and vice versa.

Look carefully at the triangle solve for x ​
luda_lava [24]

The 3 inside angles of a triangle need to equal 180 degrees. Looking at the larger outside triangle the top angle is 30 and the lower right angle is 60.

30 + 60 = 90

The lower left angle needs to be 180 - 90 = 90 degrees.

That angle is split into two angles with one given as 70.

This means X needs to be 90 - 70 = 20 degrees.

x = 20

F(x) = 3x + 2
Vinvika [58]

Answer:

g(f(x)) = 9x² + 12x + 5

Step-by-step explanation:

g(f(x))

= g(3x + 2) ← substitute x = 3x + 2 into g(x)

= (3x + 2)² + 1

to expand (3x + 2)² = (3x + 2)(3x + 2)

each term in the second factor is multiplied by each term in the first factor

3x(3x + 2) + 2(3x + 2) ← distribute both parenthesis

= 9x² + 6x + 6x + 4 ← collect like terms

= 9x² + 12x + 4

then

g(f(x)) = (3x + 2)² + 1 = 9x² + 12x + 4 + 1 = 9x² + 12x + 5
