Answer:
207
Step-by-step explanation:
ok so 72 photos in 8 minutes
So the easiest way would be to find how many photos are made per minute.
To do that you would divide 72 by 8 to get 9.
You need how many photos are made in 23 minutes.
To get that you times 23 by 9 to get 207.
207 photos are made in 23 minutes.

good luck my firesn
First calculate (-8x-15)=120
Then multiply - 11x120
=-1320
Answer:Let the two unknown numbers be x and y.
So, x-y=40 ........Equation 1
And 0.3(x)= 37.5/100 (y)
From equation 1, x=40+y
Now, multiply through by 100 in equation 2.
We have,
30x = 37.5 (y)
We can multiply through by 10 again,so that the number on the L.H.S becomes a whole number.
Therefore, we have
300x = 375 (y)
Put "x=40+y" in the equation above
That is, 300 (40+y) = 375 (y)
1200 + 300y = 375y
1200 = 375y - 300y
1200 = 75y
Divide both sides by 75 to get your y
Therefore, y =16
From equation 1, we had x= 40 + y
Therefore X = 40 + 16
X= 56
Therefore the two unknown numbers are 56 and 16 respectively.
