680 I think because if you add what happened to him and then minus it you get 170 but the injuries added together is 680 Im not sure if that's all that you need but I hope this helps XD

looks like the answer C. Thousands.
Answer:
240 students
Step-by-step explanation:
Grade 7 : Grade 8 = 5 : 3
Number of seventh grade students = 5x
Number of Eighth grade students = 3x
3x = 90
x = 90÷3
x = 30
Total students = 5x + 3x = 8x = 8 * 30 = 240
Answer:
hi! the slope formula is y2-y1 / x2-x1 ! so (-6,0) (2,-2)
your x1 is -6 and y1 is 0 and x2 is 2 and y2 is -2!
using the formula, -2-0/2--6 is 4
so your slope is 4!
the y intercept is solved by
the slope intercept formula y= mx+b
I hope you've memorized both formulas!
b is your y intercept so let's set the equation up!
pick a point it can be either point we'll do (-6,0)!
now y=mx + b
m is your slope and y is the y coordinate of the point (-6,0) that we chose!
b is what we will solve
so! 0=4(-6)+b
0= -24 + b
now it's basic algebra!
24= b
I hope this helps!
In conclusion, slope is 4 and y intercept is 24
memorize slope formula and slope intercept formula and you can do this!
