3(x-2)=X+7 <br> How can I solve this please

Hunter-Best [27]

3(x-2)=x+7

or, 3x-6=x+7

or, 3x-x=7+6

or, 2x=13

or, x=13/2

or, x= 6.5

Therefore, x=6.5

Hope it helps! :)

Joes electric made 19 customer calls last week and 25 this week. How many calls must be made next week in order to maintain an a

Mkey [24]

Answer:

At least 16 calls must be made.

Step-by-step explanation:

It is given that Joes electric made 19 customer calls last week and 25 this week.

Let x calls be made next week in a order to maintain an average of at least 20 calls per week for three week period.

$Average=\dfrac{\text{Sum of observations}}{\text{Number of observations}}$

$Average=\dfrac{19+25+x}{3}$

$Average=\dfrac{44+x}{3}$

Average at least 20.

$Average\geq 20$

$\dfrac{44+x}{3}\geq 20$

$44+x\geq 60$

$x\geq 60-44$

$x\geq 16$

Hence, at least 16 calls must be made.

Answer:

Step-by-step explanation:

Put x as -3.

2(-3) - 2

= -8

2(-3)² + 14(-3) + 5

= -19

Divide both terms.

-8/-19 = 8/19
