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.

3x+8y=27 4x+3y=13 solve the simultaneous equation
dmitriy555 [2]

Step-by-step explanation:

3x+8y=27

3x=27-8y

x=27-8y/3

4(27-8y/3) + 3y=13

36-32/3y +3y =13

36-23/3y=13

36-13=23/3y

y=3

x=1

Find the value of X
geniusboy [140]
Here, angle (3x-1) is supplementary with 5x, so their sum would be equal to 180

3x - 1 + 5x = 180
8x = 180 + 1
x = 181/8
x = 22.625

Hope this helps!
