21/3 is 7 so there are 7 pens for every 1 ratio
7 x 1 = 7
21+7 = 28
The equation is written below,
30.16 = 17.56 + 5x
First, subtract 17.56 from both sides of the equation,
30.16 - 17.56 = 17.56 + 5x - 17.56
This will give us 12.6 = 5x
Then, divide both sides of the equation by 5.
12.6/5 = 5x/5
Simplifying,
2.52 = x
Thus, the value of x is 2.52.

Answer:
7
Step-by-step explanation:
That means 4.3 (2.7) = 7
The negative signs get removed because negative × negative = positive
Answer:
<em> All real numbers less than or equal to 7</em>
Step-by-step explanation:
we have
f(x)=-(x+3)^2+7
we know that
The function is a vertical parabola open downward
The vertex is the point ( -3,7 )
The vertex is a maximum
The range is the interval-----------> (-∞,7]
That means
All real numbers less than or equal to
