Answer:
1021
Step-by-step explanation:
1+1=2 and it needs to add up to 4 so you add in another 2 in the only place left for it to go which is in the tens place because the first and last number have to be the same and 0 has to go in the hundreds place.
The answer is umu( M + m )
Answer:
20
The range of a set of data is the highest number - the smallest number
32 - 12 = 20
The range is 20
<u>solu</u><u>tion</u>
<u>-4t</u> < <u>12</u> 3t-15<-3
-4 -4 3t<-3+15
t>-3 <u>3t</u><<u>12</u>
3 3
t<4
therefore the numbers that makes both equations right is -3<t<4
Answer:
The value of x = -0.46
Step-by-step explanation:
∵ 
÷ 
∴ 
* Subtract the power of the same bases
∴ 
* Let 
∴ 
∴ 4y² - 1 = -3y
∴ 4y² + 3y - 1 = 0 ⇒ factorize
∴ (4y - 1)(y + 1) = 0
∴ y + 1 = 0 ⇒ y = -1
∴ 4y - 1 = 0 ⇒ 4y = 1 ⇒ y = 1/4
∵ 
∴ y = -1 refused (
never gives -ve value)
∴ 
⇒ insert <em>ln</em> in both sides
∵ 
⇒ <em>ln</em>(e) = 1
∴ 3xln(e) = ln(1/4)
∴ 3x = ln(1/4)
∴ x = [ln(1/4)] ÷ 3 = -0.46
