Simplify. 5 - 2(x - 3)

V125BC [204]

To solve this, we simply need to remember our rules about order of operations. They tell us that first, we should distribute the 2 with the rest of the parentheses.

5-2(x-3)
5-2x+6

Next, we should combine our like-terms.

5-2x+6
11-2x

Seeing as we do not know the value of the variable, the simplest form of the expression is 11-2x.

Answer:

5625 bald eagles

Step-by-step explanation:

Given

$y = 312.5x + 1562.5$

Required

Predict the numbers in 1998

First, we calculate the value of x

$x = 1998 - 1985$ ---- years since 1985

$x = 13$

So, we have:

$y = 312.5x + 1562.5$

$y = 312.5*13 + 1562.5$

$y = 4062.5 + 1562.5$

$y = 5625$
