Answer:
6)
a. x=35
b. x=4
c. x=30
Step-by-step explanation:
6a) 7/9=x/45
7/9×45=x
7×45/9=x
315/9=x
35=x
x=35
————————
b. 10/8=5/x
5/4=5/x
5/4x=5(the x is in the middle of the division sign here)
5x/4=5(the x is NOT in the middle of the division sign)
5x=5×4
5x=20
x=20/5
x=4
———————
c. x/34=15/17
x=15/17×34
x=15×34/17
x=510/17
x=30
hope that helped you. I can't answer number 7, I'm sorry
75*3=225+1=226=226/3
hope that helps

Answer:
x = ±sqrt(14)
Step-by-step explanation:
x^2 = 14
Take the square root of each side
sqrt(x^2) = ±sqrt(14)
x = ±sqrt(14)
Answer:
0.2637
Step-by-step explanation:
P(A) = 4 x (13/2) x 13^3/(52/5) = (rounded: 0.264) (Real answer: 0.2637)
