Answer:
Step-by-step explanation:
Use the formula Sum = (a + L)*n/2
The tricky part is n. That's the number of terms between 1 and 99 inclusive.
n = 99 -1 + 1 = 99
n = 99
a = 1
L = 99
Sum = (1 + 99)*99 / 2
Sum = (100)*99/2
Sum = 4950

Answer:
-5x + y = -27
Step-by-step explanation:
Equation: y+8 = -5(x+3)
Standard form is (ax + by = c)
We have to get x and y and their coefficients over to the left side of the equation, and all the single numbers to the right side.
y + 8 = -5 (x + 3)
y + 8 = -5x -15
y = -5x - 27
THE ANSWER IS :
-5x + y = -27
