Step-by-step explanation:
The rules For fractions: Multiple Denominator to Denominator and Numerator to numerator!
Ok: For number 1
3/5*1/1= 3/5
Number 2
3/4*9/4=27/16= 1 11/16
Number 3
14/21=2/3*33/7=66/21= 3 3/21= 3 1/7
Number 4
6/18*9/42= 1/3*3/14= 3/42= 1/14
Number 5
22/15*45/4= 33/2=16 1/2
Number 6
3/28* 35/6= 105/168= 5/8
Number 7
2/7*35/12=60/84=5/6
Number 8
16/15*21/24=16/15* 7/8=112/120=14/15
Hope It helps!!!!
Answer:
- using the rule given: 2.5
- using an exponential rule: 7
Step-by-step explanation:
Evaluating the linear rule given, for n = 1, we have ...
a1 = 7(1/2)(1) -1 = 7/2 -1 = 5/2 = 2.5
_____
We suspect you may intend the exponential function ...
an = 7(1/2)^(n-1)
Then, for n = 1, we have ...
a1 = 7(1/2)^(1 -1) = 7(1) = 7 . . . . the first term is 7
_____
When writing an exponential expression in plain text, it requires the exponential operator, a caret (^). If the exponent contains any arithmetic, as this one does, it must be enclosed in parentheses.
Your answer would be 20.. the square root of 50 is 7.07106781187 x by 8
15 miles/2.5 mph=15/2.5=6 hours left
