Answer:
I am pretty sure the answer is C.
Step-by-step explanation:
Since the total amount of quarters and dimes Javier has is 24, we can use the variables d (representing the dimes) and q (representing the quarters) and come up with <u><em>d + q = 24 </em></u>for the first part.
for the second part, we know that every dime is worth 10 cents, or, .10 and every quarter is worth 25 cents , or .25 so for the second part, we can come up with the equation<u><em> .10d + .25q = $3.75 .</em></u>

Answer:
(d-2) <-1
Step-by-step explanation:
The number be d. d minus 2 means (d-2).
(d-2) is less than -1.
It means,
(d-2) <-1
It is the required inequality.
So,
Adding 1 both sides.
d-2+1 <-1+1
d-1<0
or
d<1
Hence, this is the required solution.
To factor binomials and trinomials in one variable, you look for the common factors in the terms
<h3>How to factor a binomial and trinomial?</h3>
Binomials are polynomials with two terms while trinomial have three terms.
For instance, we have:
- Binomial: x^2 - 4
- Trinomial = x^2 + 4x + 4
To factor x^2 - 4, we use the following steps:
x^2 - 4
Express 4 as 2^2
x^2 - 4 = x^2 - 2^2
Apply the difference of two squares
x^2 - 4 = (x - 2)(x + 2)
To factor x^2 + 4x + 4 we use the following steps:
x^2 + 4x + 4
Express 4x as 2x + 2x
x^2 + 4x + 4 = x^2 + 2x + 2x + 4
Factorize
x^2 + 4x + 4 = x(x + 2) + 2(x + 2)
Factor out x + 2
x^2 + 4x + 4 = (x + 2)x + 2)
Rewrite as:
x^2 + 4x + 4 = (x + 2)^2
