Pls help! What's the answer?

Ivan

Answer:

The answer is b = 8a

Step-by-step explanation:

As, 0 x 8 = 0

2 1/2 = 5/2, 5/2 x 8 = 20

5 x 8 = 40

7 1/2 = 15/2, 15/2 x 8 = 60

10 x 8 = 80

13 1/2 = 27/2, 27/2 x 8 = 108

So all variables "a" when multiplied by 8 will give us the value in "b"

So b = 8a

Twice the product of 3and a number exceeds the sum of the number and 80 by 10.what is the number?

Hatshy [7]

First, create an equation with the criteria given.

If we let x be your number,
$2(3x) = 80 + x + 10$
( $2(3x)$ is twice the product of 3 and x, and if it exceeds $x+80$ by 10, then we add 10 to $x+80$ to make the two sides of the equation equal.)

Now, solve for $x$ .

$6x=90+x \\ 5x=90 \\ x=18$
