3/7x + 5 = 8
a: 7 2/3
b: 1 2/7
c: -7
d: 7

d

Step-by-step explanation:

3/7x+5=8

subtract 5 from both sides

3/7x=3

multiple 7/3 from both sides to cancel out 3/7 and get x alone

x= 7

D. 7

3/7x + 5 = 8

-5 -5

3/7x = 3

7•3/7x = 3•7

3x = 21

3x/3 = 21/3

x = 7

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
