If Lee starts with 100 pennies and adds groups of 10, the operation is addition. Since she does this 5 times, there is 5 different numbers Lee said.
100 + 10 = 110
110 + 10 = 120
120 + 10 = 130
130 + 10 = 140
140 + 10 = 150
Thus, all of the numbers she said were 110, 120, 130, 140, and 150.
Hope this helps! :)
Hi there!
<em><u>Answer:</u></em>
<em><u>t<1</u></em>
<em><u>*The answer must have a positive sign.*</u></em>
Step-by-step explanation:
First, you add by 3 from both sides of an equation.
And then, you add/subtract from left too right.
It change negative to positive sign.
<em><u>Final answer is t<1</u></em>
Hope this helps!

Answer:
Complementary
Step-by-step explanation:
Here the denominators are quadratics , so we need to factorise them first
1/(x²-5x) +3/(x²+2x-35)
factorising x²-5x ,
here GCF is x, so taking x out we have
x(x-5)
factorising x²+2x-35 using AC method,
we find factors of -35 that add up to give 2
(x-5)(x+7)
Since we have x-5 common in both denominators, so lcd of the rational expression will be product of x(x-5)(x+7)
lcd is x(x-5)(x+7)
