5% is .05 two decimals to the left
55 x .05 = 2.75
$2.75 is your sales tax
55+2.75=$57.75
Answer:
<h3>
9, 11, 13, 15</h3>
Step-by-step explanation:
{k - some integer}
2k+1 - the first odd integer (the least)
5(2k+1) - five times the least
5(2k+1)+3 -<u> three more than five times the least</u>
2k+1+2 = 2k+3 - the odd integer consecutive to 2k+1
2k+3+2 = 2k+5 - the next odd consecutive integer (third)
2k+5+2 = 2k+7 - the last odd consecutive integer (fourth)
2k+1+2k+3+2k+5+2k+7 - <u>the sum of four odd consecutive integers</u>
2k+1 + 2k+3 + 2k+5 + 2k+7 = 5(2k+1) + 3
8k + 16 = 10k + 5 + 3
- 10k -10k
-2k + 16 = 8
-16 - 16
-2k = -8
÷(-2) ÷(-2)
k = 4
2k+1 = 2•4+1 = 9
2k+3 = 2•4+3 = 11
2k+5 = 2•4+5 = 13
2k+7 = 2•4+7 = 15
Check: 9+11+13+15 = 48; 48-3 = 45; 45:5 = 9 = 2k+1
based on the number of mice that took part in the experiment, the total number of mice that had at least one effect is 20 mice.
<h3>how many mice had a health effect?</h3>
15 mice had at least 1 tumor while 4 mice had both a tumor and respiratory failure.
the number of mice with just a tumor is:
= 15 - 4
= 11 mice
the number of mice with respiratory failure alone is:
= 9 - 4
= 5 mice
the mice that had at least one symptom is:
= 11 + 5 + 4 mice with both
= 20 mice
question is:
what are the number of mice with at least one effect?

Answer:
The answer will always be negative
Step-by-step explanation:
The rule is if you multiply positive by positive it will equal positive.
If you multiply negative and negative it will equal positive.
But if you multiply negative and positive it will equal negative.
5x+4y=16 y=3/5x-3
y=mx+b <------ slope-intercept form
5x+4y=16
-5x -5x
============
4y=-5x+16
--------------
4
============
y= -5/4+4
Slope is -5/4
y-intercept is 4
y=3/5x-3
slope is 3/5
y intercept is -3
I can't do the graph but I'm sure you can figure it out!
Hope I helped.
