Answer:
y-3
Problem:
What is the remainder when the dividend is xy-3, the divisor is y, and the quotient is x-1. ?
Step-by-step explanation:
Dividend=quotient×divisor+remainder
So we have
xy-3=(x-1)×(y)+remainder
xy-3=(xy-y)+remainder *distributive property
Now we just need to figure out what polynomial goes in for the remainder so this will be a true identity.
We need to get rid of minus y so we need plus y in the remainder.
We also need minus 3 in the remainder.
So the remainder is y-3.
Let's try it out:
xy-3=(xy-y)+remainder
xy-3=(xy-y)+(y-3)
xy-3=xy-3 is what we wanted so we are done here.

Answer:
30
Step-by-step explanation:
5(z+4)+5(2-z) (expand parentheses by distribution)
= z(5) + 4(5) + 2(5) -z(5)
= 5z + 20 + 10 -5z
= 30
Answer:
71.4699, 81.7301.
Step-by-step explanation:
So, the following are the scores: 74
90
84
78
61
65
62
67
73
75
76
95
71
98
80
The length of the score : 15
Then, let the size of the scores be n : 15.
Then, we have to find the mean.
The first step here would be to write out an equation.
$32 ÷ 8 = ?
The reason we are doing thirty-two divided by eight is because this equation will give us the cost of one pound of Cashew Nuts.
Now we solve the equation.
$32 ÷ 8 = 4
So, this means our answer is, The <span>cost of 1 pound of Cashew Nuts is only $4.</span>
