Answer:
To work this problem out you would do it as if it were just a simple equation
7x-19<16 (you would first have to add 19 to both sides)
7x<35 (then you would divide by 7 to get the variable by itself)
x<5 ( you answer would then be 5)
Step-by-step explanation:
Answer: 
Step-by-step explanation:
Find the x-coordinate of the vertex with this formula:

In this case:

Substituting values, we get:
Now we can substitute the coordinates of the vertex into the equation
and then solve for "c".
Then:

Answer:
$20.98
Step-by-step explanation:
2 hours means two of 8.74 which equals 17.48 plus that $3.5 in a day. So she gets $20.98 when she works for 2 hours.

Answer:
the Answer is 150x + 12100 ≤ 26500
Step-by-step explanation:
The max weight is 26500 so the weight would have to be the same or less than 26500 (≤)
There is already 12100 killograms on the sipping containter so that is why you have + 12100
and you have 150x because x is the number of 150-kilogram crates
and for as many crates you have to multiply by the weight.
