Hi there!
Combining th' like terms of the expressions.
(7y² - 3y) + (8y² - 8y)
7y² - 3y + 8y² - 8y
(7y² + 8y²) + (-3y - 8y)
15y² - 11y
Hence,
Option [ 1. ] - 15y² - 11y is Correct
~ Hope it helps!
Answer:
0.1
Step-by-step explanation:
0.5/4 = 0.125
0.125 Rounded to the nearest tenth, is 0.1
Therefore, the correct answer is 0.1
I hope this helps!
Let
a------------> first number
b------------> second number
we know that
a+b=-7--------> a=-7-b----------> equation 1
a-b=14--------> equation 2
<span>I substitute 1 in 2
</span>
(-7-b)-b=14-------------> -7-b-b=14----------> -7-2b=14-------> 2b=-7-14
2b=-21---------> b=-10.5
a=-7-b-------> a=-7-(-10.5)-----> a=-7+10.5------> a=3.5
the answer is
the two numbers are
a=3.5
and
b=-10.5
