An ATM machine issues $10 and $20 notes only. On a particular day 66 notes had been issued, for a total value of 8970. Two simultaneous equations that can be obtained from this information are: 1+1=66
10x +20y =970
(a) What do r and y represent in these equations?
(b) Solve the equations to work out how many of each kind of note were issued​

answer: it is 1: 47 pm

i think the answer is b.

step-by-step explanation:

not 100% sure though.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
