Given:
five times a number = 5x
decreased by 8 = 5x - 8
is at most 10 = maximum is 10 so less than or equal to 10
more than twice the number = greater than 2x.
2x < 5x - 8 <u><</u> 10
5x - 8 <u><</u> 10
5x - 8 > 2x
****
5x - 8 <u><</u> 10 if x = 3.60 then 2x < 5x-8 <u>< </u>10
+ 8 +8 2(3.6) < 5(3.6) - 8 <u><</u> 10
5x <u><</u> 18 7.2 < 10 <u><</u> 10
÷5 ÷5
x <u><</u> 3.60
5x - 8 > 2x x > 2.67; if x = 3
+8 + 8 2x < 5x - 8 <u>< </u>10
5x > 2x + 8 2(3) < 5(3) - 8 <u>< </u>10
-2x -2x 6 < 7 <u>< </u>10
3x > 8
÷3 ÷3
x > 2.67
Answer:
-23/18
Step-by-step explanation:
-7/9 = -70/90
-5/10 = -45/90
-70-45 = -115
-115/90
-23/18
EDIT: whoops, I subtracted 45 from 70 instead of adding them. it should be correct now.
hope this helps, goodluck with your schoolwork/homework.

<em>multiples of 7 = all form numbers n×7 ; n ∈ N</em>
<em>21 = 3×7</em>
<em>29 = prime number</em>
<em>27 = 3³</em>
<em>23 = prime number</em>

Answer:
20,250
Step-by-step explanation:
To find certain percentage of a number, we first convert the percentage into decimal and then multiply that decimal with the number.
<u>Converting Percentage to Decimal Rule:</u>
- Divide the percentage by 100
So, 30% would become:
30/100 = 0.3
Now, we multiply:
0.3 * 67,500 = 20,250
