Question

read the instructions first and answer the questions​

Answer 1

Step-by-step explanation:

$d - p \geqslant 26$

$f + e \leqslant 8000$

$t + f > 420$

Answer 2

Step-by-step explanation:

1.Weight of Diana=d

Weight of Princess=p

The difference between the weight of Diana and the weight of Princess=d-p

Given that their difference at least 26

=d-p≥26

2.Total amount spends for food =f

Total amount spends on educational expenses=e

Total amount spends on both=f+e

Given that the total amount on both at most

Php.8000

=f+e≤8000

3.20 peso bill=t

50 peso bill=f

Total amount for both =t+f

given that the total amount is greater than

Php.420

=t+f>420

The above situations are related to linear equations in two variables.

and they are inequalities .

all situations having two variables.
