I'll just solve the entire equation, yeah?

Let's solve your equation step-by-step.<span><span>8+9z</span>=−6
</span>Step 1: Simplify both sides of the equation. <span><span>9z+8</span>=−6
</span>Step 2: Subtract 8 from both sides. <span><span><span>9z+8</span>−8</span>=<span>−6−8 </span></span><span>9z=−14
</span>Step 3: Divide both sides by 9. <span><span>9z/9</span>=<span>−14/9 </span></span>z=-14/9
Answer:<span>z=<span>−14/9</span></span>

a total of 408 tickets were sold for the school play. They were either adult tickets or student tickets. The number of students
Mama L [17]
<span>Given Situation:
=> There are 408 total of ticket sold for a school play
=> 3 times of the tickets are sold to students compare to the adults
=> So the ratio of the given situation is 1 : 3
=> Now, 1 + 3 = 4
Since, we need 4 parts, let’s divide 408 by 4
=> 408 / 4 = 102 – the number of tickets for adults
=> 102 x 3 = 306 – the number of tickets for students
=> 102 : 306</span>

Which expression can be used to model the phrase “ the sum of three and a number”?
olga nikolaevna [1]

Answer:

x + 3

Step-by-step explanation:

A 'sum' means addition, 'a number' is represented by a variable, in this case, I chose 'x'.  I could have picked any variable I wanted.

The sum of three and a number means:  three plus some number, which is

 3 + x       in math language.     We write variables before constants, so it gets

                  rewritten as x + 3
