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:
Well here is how i wpould solve it:
x
- -7 . = 9
2
x
- + 7 = 9 + 7
2
x
- = 16
2
x * 2 = 16 * 2
x = 32
REMEMBER: alsways do one thing to one side of the equation, as well as the other!
