D. X=3cm
Since the triangles are similar, just set up a proportion to solve for x.
4/8=x/6. Then just cross multiply and solve from there.
M 18 n n= {?}V give your answer in simplest form. N=9
We see all of them have 2 and 0.5
so therfor b+c=-2.5
so
remember
a(b+c)=ab+ac
so
8.6(-2-0.5)=8.6(-2)+8.6(-0.5)
last option
$20 a week for n weeks
$240 in total
20n=240
n = 240/20
n = 12
The answer is 12 but when you are writing this answer, be sure to show all your work.
Answer:
Step-by-step explanation:
1. 2.4 - rational
2. 74 - rational
3. 17.3333333… - rational
4. π -irrational
5. there is no number
6. –18 - rational
7. there is no number
8. 87.125 - rational
9. –30 - rational
10. –8.3 -rational
11. 58.25 -rational
12. 121 -rational
13. 4.5 -rational
14. 3 7/10 -rational
As you can see, most numbers are rational. But, when you come across pi or when you have a decimal that goes on forever without repeating (like some square roots), it tends to be irrational.
