Answer:
75 and 45
Step-by-step explanation:
woman's age= w
son's age= s
--------------
- w=s+30
- w-15=(s-15)*2 ⇒ w-15=2s-30 ⇒ w=2s- 15
comparing the two above:
- s+30=2s-15 ⇒ s= 45 ⇒ w= 75
Answer:
4/3
Step-by-step explanation:
<em>Z-</em><em>4</em><em>/</em><em>9</em><em>-</em><em>1</em><em>/</em><em>3</em><em>=</em><em>5</em><em>/</em><em>9</em>
<em>Z-</em><em>7</em><em>/</em><em>9</em><em>=</em><em>5</em><em>/</em><em>9</em>
<em>Z</em><em>=</em><em>5</em><em>/</em><em>9</em><em>+</em><em>7</em><em>/</em><em>9</em><em> </em>
<em>Z</em><em>=</em><em>4</em><em>/</em><em>3</em><em> </em><em>not</em><em> </em><em>sure</em><em> </em><em />
Answer:
Option A
Step-by-step explanation:
2001 can be divided by 3, 23, and 29 without remainders. This means that the three numbers are prime divisors of 2001.
2001/3 = 667
2001/23 = 87
2001/29 = 69
The sum of the prime divisors is 55.
3 + 23 + 29 = 55
Option A should be the correct answer.
Hope this helps.
