Child=x
Adult=y
y=3x
5.2x+9.9y=767.8
5.2x+9.9(3x)=767.8
5.2x+29.7x=767.8
34.9x=767.8
x=22
Answer:
the answer is D, because 30/2 is 15.
Answer:
???
Step-by-step explanation:
6 times 364
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 8 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute (6, - 6) into the partial equation
- 6 = - 3 + c ⇒ c = - 6 + 3 = - 3
y = -
x - 3 ← equation of line k
I'm guessing you have to simplify this?
You distribute 4 to whatever is in the parenthesis.
So
4•y=4y
4•6=24
And of course there's the 5y that stays the same.
You get 4y+24+5y
Which simplifies to 9y+24 because you can group the 4y and 5y together.
In the end, you get 9y+24.
