Show how to make ten to solve 13-7. Write in a number sentence. _-_-_-_-_=_
ser-zykov [4K]

Answer: The answer is 6.

The number sentence is

3-3=0

10-4=6

So, 13-7=6

Step-by-step explanation:

To solve 13-7, by making ten

First break 13 and write 13=10+3

Then break 7 as 7=3+4

Now to subtract 7 from 13,

Step 1. Subtract 3 (a part of 7), from 3(a part of 13) or cross 3 circles, then we have left 10-4

13-7=10+3-(3+4)=10+3-3-4=10-4

Step 2. Subtract 4 from 10 or cross 4 circles out of 10, we get 6.

The answer is 6.

Fofino [41]

Answer:

m/(1 - .8)

Step-by-step explanation:

She read 80% of her emails, which is .8 of the total.  So her unread emails would be 100% - 80% = 1 - .8

that means me can be written as:

m = (1 - .8)t

where t is the total

If we solve for t, we get:

t = m/(1 - .8)
