For the first problem you will add 4 to both sides so that n is alone ex:
n-4=-2
+4. +4

So the answer would be “add 4 to both sides”

And for the second question would be to add 4K to both sides I believe

Is it wise for a firm to employ a worker at $20 per hour when another worker does the same job for $10 per hour?
vekshin1
<span>For me,

It would be a rational decision if the first worker was more than twice as productive as the second worker.</span>

This can happen in real life, for example 2 workers are hired to do the same type of job but one worker graduated with honors, the company can give a higher pay to the worker with honors compared with the other one who graduated. 

It is up to the company on how much they would pay their workers as long as it is above the minimum wage. Though there might be hurt feelings among the workers if they each knew how much they are paid for, it is also better for the company to inform workers that they are paid this certain amount because of the following reasons (graduated w/ honors).

Find the missing base (b1) of the trapezoid. Dimensions are in CM.
Alenkinab [10]

Answer:

b1 = 9 cm

Step-by-step explanation:

The formula for area of a trapezoid is

A = 1/2 (b1+b2) *h

We know Area = 135 CM ^2, Height = 10 CM, b2 = 18 cm

Substituting these in

135 = 1/2 (b1+18) *10

Multiply 1/2*10

135 = 5 (b1+18)

Divide both side by 5

135/5 = 5/5 (b1+18)

27 = b1+18

Subtract 18 from each side

27-18 = b1+18-18

9 = b1

.) A florist wishes to make bouquets of mixed spring flowers. Each bouquet is to be made up of tulips at $10 a bunch and daffodi
LekaFEV [45]

We have the following:

1.

let x a tulips

let y daffodils

therefore:

\begin{gathered} x+y=15\rightarrow x=15-y \\ 10x+7y=(x+y)8\rightarrow10x+7y=120 \end{gathered}

solving:

\begin{gathered} 10\cdot(15-y)+7y=120 \\ 150-10y+7y=120 \\ 10y-7y=150-120 \\ 3y=30 \\ y=\frac{30}{3}=10 \end{gathered}

for x:

x=15-10=5

Therefore, the answer is 5 tulips and 10 daffodils

2.

let x a 30% silver

let y a 55% silver

\begin{gathered} x+y=800\rightarrow x=800-y \\ 30x+55y=40\cdot(x+y)\rightarrow30x+55y=32000 \end{gathered}

solving:

\begin{gathered} 30\cdot(800-y)+55y=32000 \\ 24000-30y+55y=32000 \\ 25y=32000-24000 \\ y=\frac{8000}{25} \\ y=320 \end{gathered}

for x:

x=800-320=480

Therefore, the answer is 480 pounds of 30% silver and 320 pounds of 55% silver
