Answer:
x = 9
Step-by-step explanation:
When doing these types of problems, the main goal is to get the variable by itself. Its kind of hard to explain with words so I will just use numbers.
15x + 14 = 149
(Subtract 14 on both sides. Remember, when you do something (Like subtracting, adding, etc.) on one side you have to do it to the other.)
15x + 14 = 149
-14 = -14
---------------------------
15x = 135
(Divide 15 on both sides. Since we need to use inverse operation to cancel the 15 out, we would divide 15 on both sides.)
15x/15 = 135/15
x = 9
Hope this helps :)
(8 teaspoons) / (4 cups) = 2 teaspoons per cup
(4 cups) / (8 teaspoons) = 1/2 cup per teaspoons
Answer 5r^
2
−17r+5
Step-by-step explanation:
Changes made to your input should not affect the solution:
(1): "r2" was replaced by "r^2". 1 more similar replacement(s).
STEP
1
:
Equation at the end of step 1
(((8•(r2))-12r)+4)-((3r2+5r)-1)
STEP
2
:
Equation at the end of step
2
:
((23r2 - 12r) + 4) - (3r2 + 5r - 1)
STEP
3
:
Trying to factor by splitting the middle term
3.1 Factoring 5r2-17r+5
The first term is, 5r2 its coefficient is 5 .
The middle term is, -17r its coefficient is -17 .
The last term, "the constant", is +5
Step-1 : Multiply the coefficient of the first term by the constant 5 • 5 = 25
Step-2 : Find two factors of 25 whose sum equals the coefficient of the middle term, which is -17 .
-25 + -1 = -26
-5 + -5 = -10
-1 + -25 = -26
1 + 25 = 26
5 + 5 = 10
25 + 1 = 26
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
5r^2 - 17r + 5
To be fully honest i am not fully educated in this and as a teenager myself i personally wouldnt have had done this at that age. However because it is phone sex and not real sex there is no chance of you getting STD or becoming pregnant so it it could be okay. on the other hand because you are only 15 and have GCSEs (depending on where you live) and exams coming up i wouldnt say it is the best use of your time.
if you both agree and enjoy , i dont see why you cant.
