The second choice is correct
Answer:
y=1
Step-by-step explanation:
6=2y+4
2=2y
y=1
Answer:
306 calories
Step-by-step explanation:
By looking at the problem, we can conclude the number of chicken nuggets and the calories are directly related, when the amount of chicken nuggets go up, the calories also go up, proportionally. Because of this, we can set up an equation:
6 / 204 = 9 / x
Where x is the amount of calories in 9 chicken nuggets.
Now, we can simplify by cross multiplying:
6x = 1836
x = 306 calories
16 dimes = $1.60
<em>12 quarters</em><em> </em>= $3.00
Let x= measure of angle 1
Let y= measure of angle 2
This is solving a system of equations
3x=30+ 5y which can also be written
3x-5y=30, and
2x+2y=180
There are a few ways to solve this, like solving for x in one of the equations and plugging it in for x in the other equation, but here is another way:
2(3x-5y)=2*30
3(2x+2y)= 3*180
6x-10y=60
6x+6y=540, and now subtract to get rid of x
0-16y=-480
Y=30
Plug it back in to either equation and you get x=60
