-2x-2+x^2+x+180+-2x-2=180

Dominik [7]

Answer:

x= 4, -1

Step-by-step explanation:

-2x - 2 + x^2 + x + 180 - 2x - 2 = 180

add like terms and put in descending order

x^2 - 3x + 176 = 180

subtract 180 from both sides

x^2 - 3x - 4 = 0

factor out the equation

(x-4)(x+1)=0

solve for x

x-4=0 x+1=0

x=4 x=-1

Maggie needs to spend at least six hours each week practicing the piano. She has already practiced three and one fourth hours th

vfiekz [6]

Answer:

three and one fourth + 2x ≥ 6

Step-by-step explanation:

Let

x -----> the minimum number of hours he needs to practice on each of the two days

we know that

needs to spend at least seven hours each week practicing the drums

$3\frac{1}{4}+2x\geq 6\ hours$

Convert mixed number to an improper fraction

$3\frac{1}{4}\ hours=\frac{3*4+1}{4}=\frac{13}{4}\ hours$

substitute

$\frac{13}{4}+2x\geq 6\ hours$

Subtract 13/4 both sides

$2x\geq 6-\frac{13}{4}$

$2x\geq \frac{11}{4}$

Divide by 2 both sides

$x\geq \frac{11}{8}$

therefore

The minimum number of hours he needs to practice on each of the two days is $\frac{11}{8}\ hours$
