Answer:
X=0.667
Step-by-step explanation:
3x-2=0
3x=2
X=2/3
X=0.667
So we're looking for the top half of a fraction. They all appear to equal to 5/10, which is 1/2. Whatever is 1/2 of the denominator (or twice the numerator) is our answer.
?/100; 1/2 of 100 is 50, that answer is 50/100.
3/?; 3 is 1/2 of the denominator, multiply by 2.
3/6.
2/?; multiply by 2. 2/4.
?/10; divide by 2, 5/10.
Hope this helps!
Xian = 56 stamps + 12 per month : 12m + 56
kai = 80 stamps + 8 per month : 8m + 80
when will they have same number of stamps ? set them equal.
m = number of months
12m + 56 = 8m + 80
12m - 8m = 80 - 56
4m = 24
m = 24/4
m = 6.....at 6 months, they will have the same number of stamps.
12m + 56 = 12(6) + 56 = 128
8m + 80 = 8(6) + 80 = 128
They will both have 128 stamps
