Answer:

15 dimes
5 quarters

Step-by-step explanation:

Let q represent the number of quarters Theresa has. Then the value of her coins is ...

0.25q + 0.10(20 -q) = 2.75

0.15q = 0.75 . . . . . . . . . subtract 2.00, collect terms

q = 0.75/0.15 = 5

Theresa has 5 quarters and 15 dimes.

How do I solve 5x - 4x^2

Sever21 [200]

Answer:

If you are asking,

5x - 4x^2=0

x(5-4x)=0

Either,

x=0

or,

5-4x=0

x=5/4

If factor,

5x - 4x^2

x(5-4x)

If difference,

5x - 4x^2

The same as they are not like terms.

$\huge\text{Hey there!}$

$\mathsf{2(4 - 1)^2 - 3 + 2(5)}$

$\mathsf{4 - 1 = \bf 3}$

$\mathsf{= 2(3^2) - 3 + 2(5)}$

$\mathsf{3^2}\\\mathsf{= 3\times3}\\\mathsf{= \bf 9}$

$\mathsf{= 2(9) - 3 + 2(5)}$

$\mathsf{2(9)}\\\mathsf{= \bf 18}$

$\mathsf{= 18 - 3 + 2(5)}$

$\mathsf{18 - 3}\\\mathsf{= \bf 15}$

$\mathsf{= 15 + 2(5)}$

$\mathsf{2(5)}\\\mathsf{= \bf 10}$

$\mathsf{= 15 + 10}\\\mathsf{= \bf 25}$

$\boxed{\boxed{\huge\text{Therefore, your ANSWER is: \textsf{25}}}}\huge\checkmark$
