 To get the answer do this: 

2.5% of what is 2.21

2.5%x = 2.21

2.5/100x = 2.21

0.025x = 2.21

divide both sides by 0.025

0.025x/0.025 = 2.21/0.025

x = 88.4

The quotient of a number t and 4.2 is at most 15.​
frosja888 [35]

Answer:

t \leq 63

Step-by-step explanation:

Quotient of two numbers also means the result of the two numbers after division.

If the quotient of a number t and 4.2 is at most 15., this can be expressed using the inequality;

\dfrac{t}{4.2}\leq  15 <em>(note that at most 15 means that the highest value we can have is 15 after taking the quotient of the number hence the reason of the inequality sign.)</em>

<em></em>

On solving the inequality for the variable t

\dfrac{t}{4.2}\leq  15\\\\multiply \ both \ sides \ by \ 4.2\\\\\dfrac{t}{4.2}* 4.2\leq  15 * 4.2\\\\t \leq 63

<em>Hence t is at most 63</em>

The subtracton property of equality allows you to subtract the same amount from both sides of an equation without changing the truth of the equation.
