So we'll assume the number is x.
So,
15+
= 9.
Now, we solve for x:
= 9-15
= -6
x = -6*2
x = -12
Check work:
15+
= 9
15+(-6) = 9
15-6 = 9
9 = 9
Hi!
I think that you misspelled the question, and you mean that Oliver bought "ten", not "yen" stamps- yen is the currency of Japan.
So we have 10 stamps of 77 cents each:
10*77=770 cents
He has to pay 770 cents, or since 100 cents are one dollar, 7 dollars and 70 cents.
A'B'C'D after the translation. Corresponding parts of congruent figures are congruent. Angle BCD corresponds to angle B'C'D', so angle BCD is congruent to angle B'C'D'
See attached. The graph confirms this.

Hope this helped!
Answer:
He could work 10 hours as a lifeguard, and 5 hours as a tutor
Step-by-step explanation:
If he makes $16 an hour as a lifeguard
and $18 an hour as a tutor,
He could work 10 times $16, to make $160 for 10 hours.
Now we subtract this from $250, this makes $90.
We know need to find out how many times 18 goes into 90, 5 times.
So we know that he could work 10 hours as a lifeguard and 5 hours as a tutor.
I hope this is right.
I hope this helps too, have a nice day!
