Answer: 3/4</h3>
=========================================================
Explanation:
We'll use this formula
a & b/c = (a*c + b)/c
to convert from a mixed number to an improper fraction.
John's mixed number converts to
a & b/c = (a*c + b)/c
6 & 3/4 = (6*4 + 3)/4
6 & 3/4 = 27/4
Do the same for Kerry's string
a & b/c = (a*c + b)/c
7 & 1/2 = (7*2 + 1)/2
7 & 1/2 = 15/2
We'll subtract those results to find the difference between them.
15/2 - 27/4 = 30/4 - 27/4 = (30-27)/4 = 3/4 is the final answer
Kerry's string is 3/4 of an inch longer compared to John's string.
Answer:
¾
Step-by-step explanation:
Length of Kerry string = 7(½) = 15/2
Length of John string = 6(¾) = 27/4
15/2 - 27/4
30 - 27/4
3/4

Radius = Diameter/2
Answer:
-9
Step-by-step explanation:
The applicable exponent rule is ...
a^b·a^c = a^(b+c)
___
For the y factor, ...
y^-13 · y^4 = y^(-13+4) = y^-9 . . . . . exponent of -9
Let the two numbers be x and y.
Given,
x + y = 23
x = 23 - y
Also given,
y = 2x - 1
y= 2(23 -y) -1
y = 46 - 2y - 1
3y = 45
y = 15
x = 23 - y = 23 - 15 = 8
Hence, the two numbers are 15 and 8.
It’s B or D probably B that’s just a guess though
