Answer:
x=6/7
Step-by-step explanation:
7x÷2+5=8
divide by 2 on both sides:
7x/2+5=8(it's a fraction)
subtract 5 on both sides
7x÷2=3
multiply 2 on both sides
7x=6
divide by seven on both sides
x=6/7

Answer:
c = -1
Step-by-step explanation:
6 - (3 - c) = 2
6 - 3 + -(-c) = 2
3 + c = 2
c = 2 - 3
c = -1
Check:
6 -(3-(-1)) = 2
6 - (3+1) = 2
6 - 4 = 2
I assume by starting value, you mean y-intercept. The y-intercept is 15
To find this, we need to use slope intercept form and the given information to find it.
y = mx + b ----> plug in the known values
9 = -3/4(8) + b
9 = -6 + b
15 = b
Therefore, the starting value is 15.
509 rounded to the nearest hundred would be 500
