Answer:
Lin is between 150 and 160 cm
Step-by-step explanation:
The height is represented by the inequality :
h > 150 and h < 160
h > 150 - - (1)
h < 160 - - - (2)
Combining the two :
h > 150 means 150 is less than h but h is not upto 160
Thus, we have ;
150 < h < 160
This means height, h occurs between the range ; 150 cm and 160 cm

there are 16 ounces in 1 pound. Juan is mailing a package that weighs 96 ounces. He wants to know the weights of the package in pounds
Answer:
Divide, 16.
Step-by-step explanation:
So, lets look at the unit scale.
For every 16 ounces, there are 1 pound.
To convert ounces to pounds, the number must be divide by 16, since there are 16 ounces in one pound.
The first fill in box answer is division.
Next we must ifnd the actual amount of pounds.
We know that the box weights 96 ounces.
Now lets divide this by ounces per pound, and see what we get:
96/16
=
6
So the box weighs 6 pounds.
This is the answer to the second fill in question.
Hope this helps!

Step-by-step explanation:
3 to the power 2x+3 is subtracted by 9 which is equal to 2 times 9 to the power x+1 and is subtrcted by 6
Answer:
x = -0.5
Step-by-step explanation:
Here we have the sentence:
"3 to the power 2x+3 is subtracted by 9 which is equal to 2 times 9 to the power x+1 and is subtracted by 6"
The first part:
"3 to the power 2x+3 is subtracted by 9..."
This can be written as:
[tex]3^{2x + 3} - 9[/tex]
"... is equal to 2 times 9 to the power x+1 and is subtracted by 6"
[tex]3^{2x + 3} - 9 = 2*9^{x + 1} - 6[/tex]
Let's solve this for x.
First, we can add 9 in both sides:
[tex]3^{2x + 3} = 2*9^{x + 1} - 6 + 9 = 2*9^{x + 1} + 3[/tex]
We also know the relations:
[tex]a^n*a^b = a^{n + b}[/tex]
and
[tex](a^n)^m = a^{n*m}[/tex]
We can write the left part as:
[tex]3^{2x + 3} = 3^{2x}*3^3 = (3^2)^x*3^3 = 9^x*27[/tex]
And the right side as:
[tex]2*9^{x + 1} + 3 = 2*9^x*9 + 3 = 18*9^x + 3[/tex]
Then the equation becomes:
[tex]27*9^x = 18*9^x + 3[/tex]
Now let's move both terms with 9^x to the left side:
[tex]27*9^x - 18*9^x = 3\\[/tex]
[tex](27 - 18)*9^x = 3[/tex]
[tex]9*9^x = 3[/tex]
[tex]9^x = 3/9 = 1/3[/tex]
Now remember that:
Ln(a^b) = b*Ln(a)
Then if we apply the Ln( ) function to both sides, we get:
[tex]Ln(9^x) = Ln(1/3)[/tex]
[tex]x*Ln(9) = Ln(1/3)[/tex]
[tex]x = \frac{Ln(1/3)}{Ln(9)} = -0.5[/tex]

Someone PLEASEEEE HELPPPP
Answer:
x = 18√3
Step-by-step explanation:
From the picture attached,
In a right triangle,
Measure of one angle = 30°
Measure of adjacent side of the angle = 9 units
We have to find the measure of Hypotenuse from the given properties.
By cosine rule,
cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{\sqrt{3}}{2} =\frac{9}{x}[/tex]
[tex]x=18\sqrt{3}[/tex]
Therefore, measure of Hypotenuse is 18√3 units.

What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have the following inequality -
x < - 2
Given is -
x < - 2
Now, it can be seen that -
- 3 < - 2
Therefore, only x = -3 is less than -2.

5x+7y=3914. I'm not quite sure how to write the x and y! First answer will get Brainliest, thanks!
Answer:
hanges made to your input should not affect the solution:
(1): Dot was discarded near "4.".
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
5*x+7*y-(3914)=0

Equation of a Straight Line
1.1 Solve 5x+7y-3914 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 5x+7y-3914 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 3914/7 so this line "cuts" the y axis at y=559.14286
y-intercept = 3914/7 = 559.14286
Calculate the X-Intercept :
When y = 0 the value of x is 3914/5 Our line therefore "cuts" the x axis at x=782.80000
x-intercept = 3914/5 = 782.80000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 559.143 and for x=2.000, the value of y is 557.714. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 557.714 - 559.143 = -1.429 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -1.429/2.000 = -0.714
Geometric figure: Straight Line
Slope = -1.429/2.000 = -0.714
x-intercept = 3914/5 = 782.80000
y-intercept = 3914/7 = 559.14286
Step-by-step explanation:
Answer:
y= -5/7x+3914/7
Step-by-step explanation:
Slope form is y=mx+b
5x+7y=3914
7y = -5x+3914 minus the 5x from each side
7y=-5x+3914 divide 7 from each side --> y= -5/7x+3914/7
So, 5x+7y=3914 is in ax+by=c (standard form) the "a" in "ax" can't be negative either.

Students from the local high school are selling tickets to the town's annual carnival. Adult
admission is $5.00 and child admission is $2.50. Two hours after the carnival opened its first
day, 440 tickets had been sold totaling $1900. How many adults and how many children
entered the carnival during the first two hours it was open?
Answer:
320 adults and 120 children
Step-by-step explanation:
First set up two sets of equations. One will equal the total amount of money sold and the other will equal the total amount of tickets sold.
5a + 2.5c = 1900 where a is the # of adult tickets sold and c is the # of children tickets sold
a + c = 440
Now solve for either a or c in the second equation. I chose to solve for a. a=440-c
Use that to substitue into the other equation.
5 (440-c) +2.5c = 1900
2200-5c +2.5c = 1900
-5c+2.5c = -300
-2.5c=-300
c=120
Now plug 120 into the equation a+c=440 and solve for a
