Let the numbers be n, n+2, n+4
Sum equals too= 13+2(n+4), which is 2n+21
a) Equation--> n+n+2+n+4= 2n+21
b) Solution--> 3n+6= 2n+21
=> n= 15
c) Second number--> 17 (15+2)
Third number--> 19 (15+4)
d) 15+15+2+15+4=30+21
=> 51= 51
So, the equation is true.
And pls mark me brainliesttt :)))
Answer:
21. Line b.
22. Line a.
Step-by-step explanation:
Line b is the most steep because it goes up 5, the rest goes up only 1 and 3
Line a is the least steep because it only goes up 1, while the rest go up more
8.45 = 8 45/100 = 8 9/20 = 169/20
A. 8 3/8 = 67/8
B. 8 4/9 = 76/9
C. 8 3/5 = 43/5
D. 8 5/12 = 101/12
The common denominator of all those fractions is 360, so we can write them as:
8.45 = 3042/360
A. 8 3/8 = 3015/360
B. 8 4/9 = 3040/360
C. 8 3/5 = 3096/360
D. 8 5/12 = 3030/360
As a mixed numbers:
8.45 = 8 162/360
A. 8 3/8 = 8 135/360
B. 8 4/9 = 8 160/360
C. 8 3/5 = 8 216/360
D. 8 5/12 = 8 150/360
Now we can easily see that only 8 216/360 is greater than 8 162/360. It means the correct answer is C: From the given mixed numbers, only 8 3/5 is greater than 8.45.
