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 $\frac{11}{8}\ hours$

5v + 7f =28.70 if f is 2.85

adell [148]

Hey!

First, let's write the problem.
$5v+7\left(2.85\right)=28.7$
Multiply $7$ with $2.85$ .
$5v+19.95=28.7$
Subtract $19.95$ from both sides.
$5v+19.95-19.95=28.7-19.95$
$5v=8.75$
Divide both sides by $5$ .
$\frac{5v}{5}=\frac{8.75}{5}$
$v=1.75$

Let me know if you have any questions regarding this problem!
Thanks!
