-x+y+z=1
Step-by-step explanation:
1.) 16in is the answer and then 2.)21in 3.) 24in
10% = 0.1
10% of 5 = 10% x 5 = 0.1 x 5
therefore, the answer is $0.50
Allright to find this you have to put the equation into order again. The equation of a line is y=mx+c. M= Gradient. C = Y intercept. After you put it in order you just have to read it. If you need the answers comment ill find them...
Solution:
we are given wit a number 440.
we have been asked to write Write the value of the hundreds and the value of the tens in the number 440.
Here we can write

So value of the 100th place is 400.
Value of 10th place is 40
Here 
Hence the value of the number at 100th place is 10 times more than the value of number at 10th place.
