Answer:

Option A. -6.5

Step-by-step explanation:

$6.4r-5.9r=-3.25$

Solve for r

That means ---> isolate the variable r

Combine like terns left side of the equation

$0.5r=-3.25$

Divide by 0.5 both sides

$0.5r/0.5=-3.25/0.5$

$r=-6.5$

Answer:

f(x) = x

Step-by-step explanation:

note : slope is positive 1, so the x term must be positive

also note the graph intersects the curve at y = 0, which means that they y-intercept is zero .

if we substitute this into the general equation for a line

y = mx + b, where m = +1 and b = 0,

we get y = x

or f(x) = x (in function form)

Two consecutive even numbers are such that five times the smaller number , subtracted from eight times the bigger gives 58. Find

olga55 [171]

Answer:

$14\text{ and }16$

Step-by-step explanation:

Let the smaller number be $x$ . Since they are consecutive even numbers, the larger number can be represented by $x+2$ .

Therefore, we have the following equation:

$8(x+2)-5x=58,\\8x+16-5x=58,\\3x=42,\\x=\boxed{14}$

Thus, the larger number is $x+2=\boxed{16}$
