If and only if (iff) statements are true if only both statements are true of both are false, its double implied.
Here are the implications:
If two lines are parallel then their slopes are equal.
If the slopes of two lines are equal then they are parallel.
3. 3/10 and 5/10 4. 12/20 and 15/20 5.4/8 and 7/8 6. 8/12 and 5/12 7. 3/12 and 2/12. 8. 1/2>2/5 9.1/2 = 3/6 10. 3/4<5/6 11. 6/10=3/5
Answer: evaluate what exactly? What’s the problem??
You would have the square root symbol (called a radical) over the number 72. But if you mean to simplify it, you can keep in mind that 9 x 3 = 72 and the square root of 9 is 3, so then your answer would be
3(radical)3
Hope that's not too confusing!
Given parameters:
This is a word problem. To solve problems, it is best to interpret sentence by sentence;
Six more than a number doubled;
let the number = y ;
so we have 2(y + 6)
equal =
twice a number plus three;
let the number be Z;
2Z + 3
The complete expression is thus; 2(y + 6) = 2Z + 3
