He has 16 kg 300 grams of apples left with him.

How do you do number 15 thxxx

vampirchik [111]

The simpliest way to do this is to turn both fractions into decimals

7/10 goes to 0.7 and 2/5 goes to 0.4

then the equation would be 0.7x + 20 = 0.4

hope I've helped!

Write the following using index notation

olasank [31]

Answer:

a=2^2

b=3^5

c=4^3x5^2

d=7^2x9^4

Step-by-step explanation:

All you have to do is write the number that is already there and power it by number of times it is repeated.

If there are two different numbers in a question (like c and d) you should start with the smaller number and then follow with the larger on with a x/times symbol between them.
