Inequalities- ! tricia receives a $5 allowance every week. she also earns $6.50 for every hour that she baby-sits. next week she wants to earn at least $21.25 to buy a present. write an inequality to math this equation.

6.50x + 5 = 21.25 is the answer

Step-by-step explanation:

x=2.5

m = 6.57 and n = -2

Step-by-step explanation:

To answer this question, one will have to covert the thickness of a dollar to standard notation and then compare the two values.

4.3 × 10-3 = 4.3/1000

= 0.0043

Now, compare

0.07 =compared to 0.0043

0.07- 0.0043

= 0.0657

0.0657 = 6.57 x 10^-2

A quarter is thicker than a dollar by 6.57 x 10^-2 1

m × 10n 2

Comparing 1 and 2

m = 6.57 and n = -2
