Answer:
C (if the sign after the digit 1,2,3,4 is not minus !!!)
Step-by-step explanation:
Answer: x=3
Step-by-step explanation: Hello! I hope you are having a great day :)
For this question, you will have to distribute in order to do that, you will need to multiply what's inside the parenthesis by 5. From there you get the equation 3 - 10x + 25= -2. So from this equation, we can then add the coefficients which becomes 28 - 10x = -2. We will then have to move the constant variable (28) over to the right-hand side and change the sign. Our new equation becomes -10x = -2 - 28. We then will calculate our new equation which becomes -10x = -30. Next we divide both sides by -10 in order to make -10x into just x. -30 divided by -10 equals 3. Therefore, our answer is x=3.
Hope this helps!
Solution for 1/3*-1/9y=3 equation:
<span>y in (-oo:+oo)
((-1*(1/3))/9)*y = 3 // - 3
((-1*(1/3))/9)*y-3 = 0
((-1/3)/9)*y-3 = 0
-1/27*y-3 = 0 // + 3
-1/27*y = 3 // : -1/27
y = 3/(-1/27)
y = -81
</span><span>y = -81</span>Solution for 2/3*1/5y=9 equation:
<span>y in (-oo:+oo)
((1*(2/3))/5)*y = 9 // - 9
((1*(2/3))/5)*y-9 = 0
((2/3)/5)*y-9 = 0
2/15*y-9 = 0 // + 9
2/15*y = 9 // : 2/15
y = 9/2/15
y = 135/2
y = 135/2

Answer:
b = -6
Step-by-step explanation:
14.4 = -2.4b (swap the sides of the equation)
-2.4b = 14.4 (divide both sides of the equation by -2.4)
b = -6
So you are first going to move the 7 to the other by adding it to 8. and 7 plus 8 equals 15. and then you are going to get Y by itself. and then you are going to divide 15 by 3 which equals 5. and thats your answer!!
