Answer:
96 points
Step-by-step explanation:
Ratio problems can be solved like this:
Let x equal an unknown value.
Now, we can write an equation.
7x + 10x +12x = 232
We want to find 12x, so we have to find x first. We can simplify our equation to:
29x = 232
Now, divide both sides by 29.
x=8
We then solve for 12x by multiplying 8 and 12, and get 96 points.
Number 28 equals to 9 and number 34 equals to 8
Answer:
y= -x
Step-by-step explanation:
<u>Slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept
Slope
Substitute m= -1 into the equation:
y= -1x +c
y= -x +c
To find the value of c, substitute a pair of coordinates.
When x= -7, y= 7,
7= -(-7) +c
7= 7 +c
c= 7 -7
c= 0
Thus, the equation of the line is y= -x.
