Answer:

4x + 5y = 20

Step-by-step explanation:

4x + 5y = 20

5y = -4x + 20 (Subtract 4x to isolate 5y. Put the 4x in front of the 20)

y = $-\frac{4}{5}x$ + 4 (Divide all by 5 to isolate y)

And then it's done and in slope-intercept form

$-1< -\frac{4}{5} < 0$ or $-\frac{4}{5}$ is greater than -1 but less than 0

I hope this helped :)

Helpp i dont understand

Betina is 155 centimeters tall or 1 meter and 55 centimeters

1 meter = 100 centimeters
100 + 87 = 187 , Brian’s height in centimeters

Since Bonnie is 58 centimeters shorter we will subtract 187-58 which gives us 129 centimeters.

Betina is 26 centimeters taller than Bonnie so we add 26+129 =155

Therefore Betina is 155 centimeters tall or 1 meter and 55 centimeters.

Hope this helped! :)
