Answer:
z + 7
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
The sum of z and 7
<em>z + 7</em>
<em />
Answer: z + 7
<u>If needed solve:</u>
z + 7 - 7 = 0 - 7
<em>z = -7</em>
Step-by-step explanation:
step 1. x = .484848 . . . repeats
step 2. 100x = 48.48484848 . . . (multiply by 100)
step 3. subtract x from 100x : 99x = 48
step 4. x = 48/99 (now add the 2 back in)
step 5. answer: 2-48/99.
Answer:
Step-by-step explanation:
Since ABC is an equilateral triangle, thus AB=BC=AC=x, therefore
The perimeter of ΔABC=36
⇒AB+BC+AC=36
⇒x+x+x=36
⇒3x=36
⇒x=12
Thus, AB=BC=AC=12.
Now, Since ΔADC is isosceles triangle, therefore AD=DC=y.
Perimeter of ΔADC=40
⇒AD+DC+CA=40
⇒x+y+y=40
⇒12+2y=40
⇒2y=28
⇒y=14
Therefore, AD=DC=14
Thus, Length of sides of ΔABC are AB=BC=AC=12 and Length of sides of ΔADC are AD=DC=14.
Answer:
1/5 or 20%
Step-by-step explanation:
This problem can be easily solved by finding the probability of her picking one matching pair to leave in the suitcase (which results in pulling out exactly two matching pairs)
For the first sock, it does not matter what sock she picks.
For the second sock, there is only 1 out of the 5 socks left that would match the first one picked. Therefore, the probability that she pulls out exactly two matching pairs is 1/5 or 20%
Hey there
the answer is
