75=-5(3+6m) I need this​
alisha [4.7K]
Are you finding m? If so here is the answer:

75 = -5(3 + 6m)

Distribute:
75 = -15 - 30m

Add 15 to both sides:
75 = -15 - 30m
+15 +15
90 = -30m

Divide by -30 on both sides:
90/-30 = (-30m)/-30

You should get: m = -3

3. Solve the system using
anzhelika [568]

Answer:

D. Infinite solutions.

Step-by-step explanation:

Since they give us the equation for (y) we just implement that equation in place of (y) in the second equation

15x+3y=27 now becomes

15x+3(-5x+9)=27

Distribute the 3

15x-15x+27=27

15x and -15x cancel out

27=27

Infinite solutions since both sides are exactly equal.

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Snowcat [4.5K]

Answer:

  • multiplier and multiplicand
  • factors

Step-by-step explanation:

Different words are used in different contexts. When two numbers are multiplied, one can be identified as the <em>multiplier</em>, and the other the <em>multiplicand</em>.

When two or more numbers or expressions are multiplied, they are often generically referred to as <em>factors</em>. The term <em>factors</em> can also be used to mean <em>prime factors</em>, as when we seek to express a product in terms of its factors.

There are 10 less trumpets players then saxophone players. The number of saxophone players is 3 times the number of trumpet play
rjkz [21]

Let the number of saxophone players be s.

Then, the number of trumpet players will be s-10


If saxophone players are three times the number of trumpet players then we have the relation


s=3(s-10)


This is a linear equation in s. we expand bracket to obtain,


s=3s-30

We group like terms to get,

s-3s=-30


-2s=-30


This implies that

s=15

The number of trumpet players are;

15-10=5

Therefore there are 5 trumpet players.
