Answer:
9, 11, 13
Step-by-step explanation:
Let n represent the smallest of the integers. Then n+4 is the largest of them. The given total is ...
n + 4(n+4) = 61
5n +16 = 61
5n = 45 . . . . . . subtract 16
n = 9 . . . . . . . . divide by 5
The smallest of the integers is 9, so the other two are 11 and 13.
Yes, they are equal because, (3x6) x 9= 162 and, 3x(6x9 = 162 as well! Hope it helps

Answer:
340 phones
Step-by-step explanation:
Make an expression
She repairs 10 phones each day, d.
Each day she repairs 10 phones, it is 10 phones off the total number (450) she has to repair, so we can subtract 10d from 450.
450-10d
We want to find how many she has left after 11 days, so we can substitute 11 in for d
450-10(11)
Multiply
450-110
340
She will still have 340 phones left to repair
