Answer:
3/12
Step-by-step explanation:
OR:
14 is equivalent to 3/12 because 1 x 12 is the same as 4 x 3. They both equal 12. 28 is equivalent to 3/12 because 2 x 12 is the same as 8 x 3. They both equal 24.
Answer:
length 5cm, width 4cm, door width 2/5cm or. 4cm, length 10 ft, width 7.5 ft
equation of a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given
(1,-2) and slope of 1/3
y-(-2)=1/3(x-1)
general form is ax+by=c (or ax+by+c=0) where a,b,c are integers and a is positive
y-(-2)=1/3(x-1)
y+2=1/3(x-1)
times both sides by 3
3y+6=x-1
minus 3y both sides
6=x-3y-1
add 1 both sides
7=x-3y
x-3y=7
To get ax+by+c=0 form, subtract 7 from both sides to get
x-3y-7=0
The answer is $13
Explanation:
You would first have to find 25% of the original amount. To do so, you must multiply the decimal amount of the percentage (0.25) by the number. The product is 20, or $20. So now that you have found the amount that you have spent your money on shorts, now you must find 65% of 20 to find the sandal spending amount. 0.65 * 20 = 13, or $13. Therefore, you spent a total of $13 on the sandals.
Hope I helped and good luck!
