Answer:

3/2 0r B. 1 1/2

Step-by-step explanation:

Step 1: Cross-multiply.

4/2=3/x

4*x=(3)*(2)

4x=6

Step 2: Divide both sides by 4.

4x/4=6/4

x=3/2

Answer:

x=3/2

3/2 is an equivilant to B 1.5 or 1 1/2

What is the sum of the finite arithmetic series (-5)+0+5+10+ ......+65

Alex17521 [72]

If you want to solve this problem using formulas, there are two important formulas:

t1 = first term = -5

tn = nth term = last term = -5

n = numbr of terms

Sn = sum of the n terms

tn = t1 + (n - 1)d ---> 65 = -5 + (n - 1)(5)

65 = -5 + 5n - 5

65 = -10 + 5n

75 = 5n

n = 15

Sn = n(t1 + tn)/2 ---> Sn = 15(-5 + 65)/2

Sn = 450

So ur answer rounds up to 450
