-- Remember how to find an average:
           -- Add up all the items on the list.
           -- Divide the sum by the number of items on the list.

-- John's first 3 test scores were 94, 98, and 98 .

-- His score on the 4th test will be 'F' .

-- His average after the fourth test will be

                                   (94 + 98 + 98 + F) / 4 .

-- He wants that average to be 96. 

                             96  =  (94 + 98 + 98 + F) / 4

There's your equation.

Please solve each algebraically : a) 5w= 30 b) 3x - 5 = 16 c) 10 - t = 17 d) n/5 = 18 e 4w -12 =2w + 3 THANK YOU!
alina1380 [7]

Answer:

w=6, x=7, t=7, n=90, w=15/2

Step-by-step explanation:

a) 5w = 30

30/5 = 6

w=6

b) 3x-5=16

Add 5 to each side.

3x+5=16+5

3x=21

21/3=7

x=7

c) 10-t=17

10-t=17

17-10-7

-t=-7

Negative and a negative is a positive.

t=7

d) n/5 = 18

n=18 * 5

n=90

e.) 4w-12=2w+3

4w=2w+3+12

4w=2w+15

4w−2w=15

2w=15

w= 15/2
