Answer:
s + s + 6 = 44
2s = 38
2s + 6 = 44
Step-by-step explanation:
Given parameters:
Length of the board = 44inches
Unknown:
equation to find the shorter piece s = ?
Solution:
let the longer piece = L
Shorter piece = s
s + L = 44 ---- i
Now,
L = s + 6 ----- ii
put L = s + 6 into i;
s + s + 6 = 44
2s + 6 = 44
2s = 44 - 6
2s = 38
Answer:
60, 120 and 180.
Step-by-step explanation:
It maps onto itself every 60 degrees.
So as they are multiples of 60 it will map onto itself at 120 and 189 degrees also.
Answer:
m = -1, b = -4
Step-by-step explanation:
Since the line is already in slope-intercept form, we can clearly see the slope and y-intercept. The slope is -1, and the y-intercept is -4. To graph this line, you can first plot the y-intercept, (-4,0) and then plot another point by substituting a value of x into the equation. Hope this helps!
Answer:
Christian reads 3/8th of a book a week.
Step-by-step explanation:
In order to find this amount, we need to multiply both numbers by a factor that will get the weeks to equal 1. In order to get 2/3 to equal 1, we need to multiply by 3/2 (the reciprocal). Now knowing this, we can multiply the number of books by that same fraction to get the amount of books in one week.
1/4 * 3/2 = 3/8
