(50 3/4)-((2/5) x (50 3/4)

=30.45

=30.45/1

=30.45/1 x 100/100

=3045/100

=3045÷5/100÷5

Graph the function f(x) = -3/5x+8.

emmasim [6.3K]

Answer:

The y-intercept is at (0,8), so you can graph that point. Then the slope is -3/5. So the change in y coordinate divide the change in x coordinate is always -3/5. Thus 8-y/0-x=-3/5. You can choose any value for y and x as long as 8-y=-3. And 0-x=5. The point on the graph will just be (x,y) for the values you find.

Answer:

$w>48$ pounds

Step-by-step explanation:

The customer will be charged extra if the weight of their suitcase is above 48 pounds.

Let the weight of the suitcase = w (in pounds)

Therefore, w above (greater than) 48 pounds is written mathematically as:

$w>48$ pounds

This is the inequality that represents w, the weight of the suitcase in pounds, that will have an extra charge.

For each hour he babysits, Anderson earns $1 more than half of Carey’s hourly rate. Anderson earns $6 per hour. Which equation c

Illusion [34]

Answer: Our required equation would be $6=\dfrac{c}{2}+1$

Step-by-step explanation:

Since we have given that

Amount that Anderson earns per hour = $6

According to question, Anderson earns $1 more than half of Carey's hourly rate.

Let the hourly rate of Carey be 'c'.

So, it becomes,

$6=\dfrac{c}{2}+1$

And the value of c would be

$6=\dfrac{c}{2}+1\\\\6-1=\dfrac{c}{2}\\\\5=\dfrac{c}{2}\\\\c=\$10$

Hence, our required equation would be $6=\dfrac{c}{2}+1$

Simplify this expression.

amm1812

Answer: 0.88

Step-by-step explanation:

Okay -5.37 + 8.14 = 2.77 ( you can simply plug this into the calculator or you could switch the problem around so it’s 8.14 - 5.37, either way you’ll get 2.77)

And then you take 2.77 -1.89 = 0.88

So 0.88 is your answer
