Answer:
Rhe first question answer is and the second question answer is c
The smaller number=x
the larger number=10x
we can suggest this equation:
10x-x=81
9x=81
x=81/9=9
The smaller number is 9
The larger number is : 10x=10(9)=90
Answer: the larger number is 90.
Remember some basic rules
and
![x^ \frac{m}{n}= \sqrt[n]{x^m}](https://tex.z-dn.net/?f=x%5E%20%5Cfrac%7Bm%7D%7Bn%7D%3D%20%5Csqrt%5Bn%5D%7Bx%5Em%7D%20%20)
so
1/2-2/7=
7/14-4/14=
3/14
![x^ \frac{3}{14}= \sqrt[14]{x^3}](https://tex.z-dn.net/?f=x%5E%20%5Cfrac%7B3%7D%7B14%7D%3D%20%5Csqrt%5B14%5D%7Bx%5E3%7D%20%20)
Answer:
The inequality 44x + 1230 ≥ 6000 can be used.
Step-by-step explanation:
Number of members = 44
Amount to raise = $6000
Amount already raised = $1230
Let,
x be the amount each member needs to raise.
44x + 1230 ≥ 6000
Therefore,
The inequality 44x + 1230 ≥ 6000 can be used.
