<span>1. Find the sum. -5 + ( -1 ) + 6 + 4
</span> -5 + ( -1 ) + 6 + 4
= -5 -1 + 10
= 4
answer <span>B: 4
</span><span>2. Add -10 + ( -5 ) + 15
</span><span> -10 + ( -5 ) + 15
= -10 - 5 + 15
= -15 + 15
= 0
answer
</span><span>B: 0</span>
Answer:
- n + q = 25
- 0.05n + 0.25q = 4.05
Step-by-step explanation:
<em>Two equations</em> are required to represent this problem as posed.
1. An equation for the number of coins:
n + q = 25
2. An equation for the value of the coins:
0.05n + 0.25q = 4.05
You can make a ratio of red to overall colors and then that will give you the fraction, you might have to simplify it
You must remember that a polynomial is written like so...
ax^2 + bx + c
In this case...
a = 1
b = 10
c = 21
To factor you must find two numbers who both add up to b (10) AND multiply to c (21)
3 + 7 = 10
3 * 7 = 21
so...
(x + 3 )(x + 7)
