Help me answer this thanks

Answer:

c = 15 meters

Step-by-step explanation:

This is solveable using the Pythagorean Theorem,

let's say a = 9 and b = 12,

a^2 + b^2 = c^2, so

9^2 + 12^2 = 225 then,

sqrt(225) = 15, so c = 15 m

Negative solution for Multi-step equations

nydimaria [60]

Answer:

$\frac{1}{2}(4x+6)+3x=7x+9$

$\frac{1}{2}(4x+8)+3x=7x+9$

Step-by-step explanation:

By putting the numbers in the given equation,

$\frac{1}{2}(4x+6)+3x=7x+9$

2x + 3 + 3x = 7x + 9

5x + 3 = 7x + 9

(5x + 3) - 7x = (7x + 9) - 7x

(5x - 7x) + 3 = 9

-2x + 3 = 9

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

-2x = 6

$-\frac{2x}{2}=\frac{6}{2}$

-x = 3

x = -3

Therefore, our equation is correct which has a negative result.

In place of 6 if we use 8, value of x will be negative again.

If a country's debt to GRD ratio is 84 the country is producing more than it is borrowing True or False

dolphi86 [110]

Answer:

True

Step-by-step explanation:

We know that the debt-to-GRD ratio is 84% and we also know that debt-to-GDP ratio of 100% means that a country's debt is equal to its gross domestic product. The higher the ratio, the less likely a country will be able to repay its debt.

For that reason if a country debt-to-GRD ratio is 84% then, the country is producing more than it's borrowing.
