Answer:
x = 40
Step-by-step explanation:
.80x + 30 = 1.20x + 14
-.80x = -.80x
30 = .4x + 14
-14 = -14
16 = .4x
16/.4 = .4/.4x
40 = x

Answer:
10. needs work
11. correct
12. correct
13. correct
Step-by-step explanation:
In general, it is a good idea to write a statement that answers the question asked. Simply solving an inequality for "x" rarely answers the question (unless it is a question that asks for the value of "x"). It is often best to try to use the wording that the question uses.
It is also a good idea to say what your variable represents.
__
10.The required relation is "cheaper than" so the "or equal to" case does not apply. The variable represents messages, so the solutions will be integers.
"Nadine can send and receive more than 33 messages so the unlimited plan is cheaper."
__
11."Becky can afford at most 8 fish."
__
12."Loretta must drive more than 260 miles farther to reach Pensacola."
__
13."Terri can spend at most 35 minutes listening to music."
_____
Additional comment
The wording of the question in problem 10 is unconventional, but we have elected to use it anyway in the above answer. We could write "The unlimited plan is cheaper if Nadine sends and receives a total of more than 33 messages."

You sit in the bleachers at a concert. The angle of depression from your horizontal sight to the stage is 24 degrees. If your seat is 45 feet above the stage level what is your actual distance d from the stage
Answer:
x=111ft
Step-by-step
sin 24 = 45/x
+ the parallel lines
45 +x+24
x= 45/sin 24
The actual distance of your from the stage is 111 feet.
What is angle of depression?The angle formed by the line of sight and the horizontal plane for an object below the horizontal is called angle of depression.
What is sine of an angle?The sine (sin) of an acute angle in a right angled triangle is the ratio between the side opposite the angle and the hypotenuse of the triangle.
According to the given question
We have
Angle of depression = 24degrees.
Let d be the actual distance of your from the stage.
Now in right angle triangle ABC
We have
AC = 45 feet
And, ∠ABC = 24 degrees
Now the Sine of an angle ∠ABC is given by
[tex]sin24 = \frac{AC}{AB}[/tex]
⇒[tex]sin24=\frac{45}{d}[/tex]
⇒ [tex]0.406=\frac{45}{d}[/tex]
⇒ [tex]d =\frac{45}{0.406}[/tex]
⇒[tex]d = 110.64 feet[/tex] or [tex]111feet[/tex]
Hence, the actual distance of your from the stage is 111 feet.

Solution to the system of equation y = 0.7x − 2 and 2x + y = 25 is (- 27, - 9).
What is a linear equation?A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Given are two equations y = 0.7x − 2 and 2x + y = 25.
Now let us write these equations in a similar manner.
y = 0.7x − 2 ⇒ - 0.7x + y = - 2...(i)
2x + y = 25...(ii)
Now subtracting eqn(i) from eqn(ii) to cancel out the term y we get
2.7x = - 27.
x = - 10 and substituting the value of x in any one of the equations we get
y = 0.7(-10) - 2.
y = - 7 - 2.
y = - 9.
So, one of the solutions to the system of equations is (- 27, - 9).

Hiro biked 52 miles in 4 hours. What was his speed in miles per hour?
Answer: 13 miles per hour
Step-by-step explanation: 52 divided by 4 to find unit rate
The speed of bike which covers 52 miles in 4 hours is 13 miles per hour.
What is speed?In unit time the distance covered by any object is called speed.
In mathematical term, Speed is express as S=D/T,
where S=speed, D=distance, T= time.
Given that,
The distance covered by bike in 4 hours = 52 miles.
To find the speed of the bike,
Use formula
Speed = distance / time
Since, distance is 52 miles and time is 4 hours,
Therefore, speed = 52 / 4 = 13 miles per hour
The required speed of bike is 13 miles per hour.

Answer:
150
Step-by-step explanation:
Using the unitary method,we can say that 150 liters of olive oil it will make.
What is unitary method?The unitary method is a technique in mathematics for solving a problem by finding the value of a single unit, I.e.,1,(by dividing) and then finding the necessary value by multiplying the single unit value.A method of solving a problem that involves first determining the value of a single unit,And then multiplying that value to determine the required value.According to the question,
40 pounds of olives to make 3 liters of olive oil.2000 pounds of olives will make 150 liters of olive oil. 3/40= 0.075 0.075 * 2000150hence,We may estimate that 150 liters of olive oil will be produced using the unitary approach.
