Solve the equation.

Mathematics
1 answer:
liq [111]3 years ago
8 0

Answer:

The answer is<em>  B. 4</em>

Step-by-step explanation:

To solve this you work out the right side first by multiplying 4*(-10.3)*2= -82.4 making the equation (-10.3)*2*x=-82.4. Multiply 2 *(-10.3)= -20.6. (-20.6)*x=-82.4. Then because (-20.6) is multipled by x to get -82.4, you must divide both sides by -20.6,  Making it <em>x=4</em>

If 2a/4=b/4 and b≠0, what does 5b equal in terms of a?
dedylja [7]

Step-by-step explanation:

you must have made a typo here.

none of the answer options are correct for the given problem.

let me just show you what you told me, and how I can solve at least this :

2a/4 = b/4

this simply means (multiply both sides by 4) :

2a = b

so, 5b is then (multiplying both sides by 5) :

5×2a = 5b

10a = 5b

but again, "10a" is not among the offered answers.

so, I don't know if you made a mistake with the basic problem or with the answer options.

Answer:

24.08

Step-by-step explanation:

We use the Pythagorean theorem and we get (16)^2 + (18)^2 = (x)^2

256 + 324 = x^2

x^2 = 580

x is about 24.08.
