Answer: the correct answer is b x=11
Step-by-step explanation:
2x - 3x + 3x = 5x + 30 + 3
2x = 5x + 33
( 2x - 5x = 5x + 33 - 5x
(1/3)-3x = 33x (1/3) Here we divide it but since it is 1/3, it is the same as dividing 3 divided by 11
1x = 11
x=11
Answer:
the answer is 94.2
Step-by-step explanation:
Answer:
9.058 is less than 9.24
Step-by-step explanation:
there is 0 in the tenth digit and there is 2 in the tenths digit so therefor, 9.058 is less than 9.24
Hope this helps:)
Angles in a line = 180
180-165 = 15 degrees
15 + 45 + ? = 180
60 + ? = 180
? = 120
This is a geometric sequence because each term is twice the value of the previous term. So this is what would be called the common ratio, which in this case is 2. Any geometric sequence can be expressed as:
a(n)=ar^(n-1), a(n)=nth value, a=initial value, r=common ratio, n=term number
In this case we have r=2 and a=1 so
a(n)=2^(n-1) so on the sixth week he will run:
a(6)=2^5=32
He will run 32 blocks by the end of the sixth week.
Now if you wanted to know the total amount he runs in the six weeks, you need the sum of the terms and the sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r) where the variables have the same values so
s(n)=(1-2^n)/(1-2)
s(n)=2^n-1 so
s(6)=2^6-1
s(6)=64-1
s(6)=63 blocks
So he would run a total of 63 blocks in the six weeks.
