(4y-y)x(9+4x+3y)
Subtract the terms 3yx(9+4x+3y).
Add the terms 3yx(4x+3y+9).
Apply the distributive property
3yx4x+3yx3y+3yx9.
Multiply the terms 12xy+3yx3y+3yx9.
Multiply the terms 12xy+9ysq+3yx9.
Solution = 12xy+9ysq+27y..............
(Note I put sq because my phone don’t allow 2 on a y)

Step-by-step explanation:

(4y-y)(9+4x+3y)

36y+16xy+12y^2-9y-4xy-3y^2

collect like terms

36y-9y+16xy-4xy+12y^2-3y^2

=27y +12xy+9y^2

Ally and Beck went fishing and caught a total of 75 fish. At home,
tigry1 [53]

Answer:

<em>Beck actually caught 45 fish</em>

Step-by-step explanation:

<u>System of Equations</u>

We call the following variables:

x = number of fish Ally caught

y = number of fish Beck caught

They caught a total of 75 fish, thus:

x + y = 75      [1]

If Ally had caught twice as much fish as she actually did, and Beck had caught three times as many fish as he actually did, then Ally would have caught 75 fewer fish than Beck, thus:

3y = 2x + 75      [2]

From [1]:

x = 75 - y      [3]

Substituting in [2]:

3y = 2(75 - y) + 75

Operating:

3y = 150 - 2y + 75

Simplifying:

5y = 225

Dividing by 5:

y = 45

Beck actually caught 45 fish

Nata [24]

Answer:

90,747

Step-by-step explanation:

Clair delivery=79 per day

Total delivery per year=79×365 days

Reagan delivery=2490 per month

Total delivery per year=2490×12 months

=29,880

Anthony delivery= 616 per week

Total delivery per year =616×52 weeks

Total delivery altogether in a year=28,835+29,880+32,032

=90,747
