Answer:
<h2>11x - 5</h2><h2> or</h2><h2>
x = -5 / 11</h2>
Step-by-step explanation:
3 (2x - 5) + 20 + 5x
= 6x - 15 + 20 + 5x
= 6x + 5x = 15 - 20
= 11x - 5
or if you are looking for x:
then x = -5 / 11
11 meters because if you do 14.3-5.8=8.5 then it said he went up so now you do 8.5+3.2=11.7 but instead of rounding up she rounded down (I think that’s the answer)
To solve equations like this we need to do inverse operations.
First we need to build an equation: 9+3x=21
We pass the nine to the other side, subtracting the 9 to 21, that leaves us with 3x=12
After that we just divide 12 by 3, wich gives us x=4, or, as it says in the question: n=4
Now let's double check:
N=4, since 3*4=12 and 12+9=21
Hope it is helpful :)
Answer:
Step-by-step explanation:
Okay This is what is happening...
$955 total - $435 painting= $520 doll profit
First, subtract the painting Danika sold from the total. This will give you the amount she earned from the doll collection. Then, divide by the dollar amount to give the amount of dolls sold.
$520 doll profit divided by $20 = $26 fir each doll
or
Equation: 955=435-20d
Variable: d= number of dolls sold
Solve Equation: 955=435-20d
-435=-435
955-435=435-435-20d
520=20d
/20=/20 (I used "/" as my divide sign you can use the other one)
520/20=20/20
26=d
Final Answer: 26=dolls sold
