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:

$y = 312.5x + 1562.5$

$y = 312.5*13 + 1562.5$

$y = 4062.5 + 1562.5$

$y = 5625$

29 — 6x=5(1 – 6x) Please show me the steps

Lady bird [3.3K]

Answer:

x= -1

Step-by-step explanation:

START 29 - 6x = 5(1 - 6x)

1. Distribute

29 - 6x = 5 - 30x

2. Isolate the variable

~ 2a. Add 30x to both sides

29 - 6x + 30x = 5 - 30x + 30x

~ 2b. Subtract 29 from both sides

29 - 29 - 6x + 30x = 5 - 29 - 30x + 30x

3. Simplify

24x = -24

4. Solve

x = -1

END
