Answer:
a.) 
b.) 
c.) $
Step-by-step explanation:
a.) If she earns $7 'per' hour, this multiplication. After a week, we need to see how many hours she worked to earn $91, so this goes behind the equal sign. Let <em>h</em> be the unknown number of hours:

Solve for h. Divide both sides by 7:

Sylvia worked 13 hours at a rate of $7 an hour.
b.) She can work at most 15 hours a week. At 'most' can also mean less than or equal to. Let <em>h</em> be hours:

Sylvia can work less than or equal to 15 hours per week.
c.) If Sylvia can work 15 hours, plug in this value for <em>h</em> into an equation when she earns $7 per hour. Let the product of the hours and money equal <em>t</em> for total:

The most money Sylvia can earn in a week is $105.

Answer:
3 kg = 105.82 ounces
Step-by-step explanation:
We have,
1 ounce = 28.35 g
and
1 kg = 2.21 lb
If we want to the value of 3 kg to ounces. The direct relation between kilogram to ounce is as follows :
1 kg = 35.274 ounces
It means,
3 kg = 105.82 ounces
So, the value of 3 kg is equal to 105.82 ounces.

Answer:

Step-by-step explanation:

(a) Rename h(x) as y

(b) Solve for x :

(d) Switch x and y

(e) Rename y as the inverse function

The graphs of inverse functions are reflections of each other across the line y = x.
In the diagram, the graph of h⁻¹(x) is the reflection of h(x) about the line y = x.
