10 is 8% of a, and 5 is 4% of b. c equals b/a. What is the value of c?? step by step explanation pls...
klio [65]

Answer:

c = 1

Step-by-step explanation:

"10 is 8% of a":     0.08a = 10, or <u>a = (10/0.08)</u>

"5 is 4% of b":      0.04b =  5, or <u>b = (5/0.04)</u>

"c equals b/a":       c = (b/a)

----

What is the value of c?

c = (b/a)

c = ((5/0.04)/(10/0.08))

c = (5/0.04)*(0.08/10)

c = (5/10)*(0.08/0.04)

c = (1/2)*(2)

<u>c = 1</u>

X + 2(y-6) = 0
Karo-lina-s [1.5K]
2x - z = 4
6x - 5z = 18
3z - 2w = -18
If u want me to solve them it’s
1. X = -2y + 12
2. x = 10 - 4/3y | for y, y = 15/2 - 3/4x
3. x = 2+ 1/2z | for z , z = -4 + 2x
4. x = 3 + 5/6z | for z , z = - 18/5 + 6/5x
5. W = -3/2x + 13/2 | for x , x = -2/3w + 13/3
6. x = -5w + 13 | w = -1/5x + 13/5

Answer:

x^2+14x+49    ( it could be polynomial because it has 3 terms and each term has a whole number and a coefficient)

Step-by-step explanation:

(x+7)^2

(x+7)(x+7)

x^2+7x+7x+49

x^2+14x+49

I am not sure it's a polynomial or not
