Devon became a waiter at a fancy restaurant. He makes $9 per hour. One night he made $150 in tips. How many hours did he work if he made a total of $226.50.
Answers
Answer:
9x + 150 = 226.50
Step-by-step explanation:
Devon makes $9 per hour. So, that signalizes "9x" (x representing the amount of hours he worked)
$150 represents how much he made one night, so you would add that to 9x. (9x + 150)
Finally, it gives you the total amount: 226.50
In conclusion, your equation should be: 9x + 150 = 226.50
Im trying to do IXL and I dont understand the way my teacher teaches (ironic right?)
the points (-9,-3) and (-2,r) fall on a line with a slope of 1/7. What is the value of r?
If its not right im gonna report you
Answers
Answer:
r = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to [tex]\frac{1}{7}[/tex]
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 9, - 3) and (x₂, y₂ ) = (- 2, r)
m = [tex]\frac{r+3}{-2+9}[/tex] , that is
[tex]\frac{r+3}{7}[/tex] = [tex]\frac{1}{7}[/tex] ( cross- multiply )
7(r + 3) = 7 ( divide both sides by 7 )
r + 3 = 1 ( subtract 3 from both sides )
r = - 2

During a road trip, Daysia keeps track of the time she spends driving, t, and the distance she drives, d. Which best describes the variable t and d ? Choose the correct answer.
a
The variable d, distance is the independent variable because it determines the amount of time spent driving, t.
b
The variable d, distance is the dependent variable because it depends on the amount of time spent driving, t.
c
The variable d is independent of variable t, and variable t is independent of variable d.
d
Both variables are dependent variables because they depend on the speed at which Daysia drives

3,560 crates
Answers
Answer: 356 crates

1 pound = 16 ounces
160 ounces = 10 pounds
if 1 crate is 10 pounds then 3560 pounds contains 3560/10 crates.
