Six times the sum of half a number x and 12 is 30

Mathematics
1 answer:
Assoli18 [71]1 year ago
7 0

Answer:

-14

Step-by-step explanation:

Translate the words to an equation

6(\frac{x}{2} + 12) = 30

Divide both sides by 6

\frac{x}{2} + 12 = 5

Multiply both sides by 2

x + 24 = 10

Subtract 24 from both sides

x = -14

Equation álgebra<br> 3x^2 = 12<br> a. +3<br> b. +2<br> C. +3.5<br> d. +1.5
Tom [10]

Answer:

x=-2,2

Step-by-step explanation:

Since this is a quadratic equation, -2 or 2 could be the possible answer

Steps

$3x^2=12$

$\mathrm{Divide\:both\:sides\:by\:}3$

$\frac{3x^2}{3}=\frac{12}{3}$

$\mathrm{Simplify}$

$x^2=4$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

$x=\sqrt{4},\:x=-\sqrt{4}$

Show Steps

$\sqrt{4}=2$

Show Steps

$-\sqrt{4}=-2$

$x=2,\:x=-2$
