Answer:
z/y
Step-by-step explanation:
the quotient of z and y
this does no require any work just understand the question
the quotient of z and y means z divide by y
z/y
Answer: 44
Step-by-step explanation:The way to calculate the number of coins that she had originally is to look at the difference in coins that changed hands. She sold 12 coins, but only bought 7 new ones. 12-7=5. Lucinda now has 5 coins less than what she started out with. So, she has 39 now, and then add 5 and the answer is 44 coins.
If x=16-4y then in your other equation 3x+4y=8 you can put that where x is to get:
3(16-4y)+4y=8
Then multiply brackets to get:
48-12y+4y=8
Simplify:
48-8y=8
Rearrange:
40=8y
Divide through by 8:
y=5
Then put y=5 back into x=16-4y to get x:
x=16-4(5)
x=16-20
x=-4
Answer:
The third (y=2x–5)
Step-by-step explanation:
y=2x–5
if we substitute then:
3=2(4)–5
3=8–5
Answer:
6 > x > -7
Step-by-step explanation:
-8 < x - 1 < 5
+1 + 1 + 1
_____________
-7 < x < 6
The above answer is written in reverse, which is the exact same result.
