Let the Addison's candy count be a and Ronny's be r.

Then a = r - 15. This is an equation.

If you had a second equation, you could replace a with the expression (r - 15), which in itself is not an equation.

Let Ronny's candy be x and Addison's candy be y. Then it would read y=x-15.

This is an equation because this is saying that Ronny's amount of candy minus 15 is equal to amount of candy that Addison has. Once there is a useful equal then it is equation.

Answer:

Step-by-step explanation:

Group like terms 6y-2y= 2-1-2

De las soluciones de la siguiente ecuación: x2 + 8x − 30 = 18? Cual es el numero de mayor valor Entre.

vekshin1

Answer:

The correct answer is "x = 4" and "x = -12".

Step-by-step explanation:

The given equation is:

⇒ $x^2+8x-30=18$

On subtracting "18" from both sides, we get

⇒ $x^2+8x-30-18=18-18$

⇒ $x^2+8x-48=0$

On applying factorization, we get

⇒ $x^2+12x-4x-48=0$

On taking common, we get

⇒ $x(x+12)-4(x+12)=0$

⇒ $(x-4)(x+12)=0$

⇒ $x-4=0$

$x=4$

or,

⇒ $x+12=0$

$x=-12$

Find the equivalent expression 9 ( 2a + 1

aivan3 [116]

Answer:

Equivalent expression of $9(2a+1)$ is, $18a+9$

Step-by-step explanation:

The distributive property says that:

$a \cdot (b+c) = a\cdot b + a\cdot c$

Given the expression: $9(2a+1)$

Apply the distributive property:

$9 \cdot (2a) +9 \cdot 1$

Simplify:

$18a+9$

Therefore, the equivalent expression of $9(2a+1)$ is, $18a+9$
