The solution to the inequality -1.5(4x + 1) > 4.5 -2.5(x + 1) is x > 7/16.
How do we determine the value?Start by simplifying the expressions on both sides of the inequality:
-1.5(4x + 1) = -6x - 1.5
and
4.5 - 2.5(x + 1) = 4.5 - 2.5x - 2.5
Now that the expressions are simplified, substitute them back into the inequality:
-6x - 1.5 > 4.5 - 2.5x - 2.5
Solve for x by adding 2.5x to both sides and subtracting 4.5 from both sides:
-3.5x > 1
0.5x > 1
Finally, divide both sides by 0.5 to get:
x > 2
So the solution set is x > 2.

A suit sells for one hundred thirty-eight dollars. A store employee bought the suit, using his employee discount of forty-five percent. What was the amount of his discount?
Answer:
$62.10
Step-by-step explanation:
To calculate how much the employee's discount actually was, we just multiply the original price by the discount
Plug the prices in --> 138 x 45/100
Simplify 45/100 --> 9/20
138/1 x 9/20 = 1242/20
1242/20 = 62.1
62.1 = $62.10
and thus, the discount is $62.10
Answer:
$63.10

MATH PROBLEM!! PLEASE HELP!!
Explain your answer please
========================================
Work Shown:
Use law of cosines to find angle B
b^2 = a^2 + c^2 - 2*a*c*cos(B)
9^2 = 6^2 + 12^2 - 2*6*12*cos(B)
81 = 36 + 144 - 144*cos(B)
81 = 180 - 144*cos(B)
81 - 180 = -144*cos(B)
-99 = -144*cos(B)
-144*cos(B) = -99
cos(B) = (-99)/(-144)
cos(B) = 0.6875
B = arccos(0.6875)
B = 46.5674634422102
B = 47 when rounding to the nearest whole number
Make sure your calculator is in degree mode.
arccos is the same as inverse cosine often labeled [tex]\cos^{-1}[/tex] on calculators.
What is the closest perfect square greater than 54
Answer:
64
Step-by-step explanation:
Perfect squares are integers multiplied by themselves.
2 times 2 = 43 times 3 = 94 times 4 = 15The closest perfect squares to 54 are 49 (7^2) and 64 (8^2).
49 is less than 54, so that's ruled out.
Therefore, the closest perfect square to 54 that is greater than it is 64.

Find an
equation of the line through (1,8) and parallel to y = 4x + 3.
In slope intercept form
Answer:
The answer is
[tex]y = 4x + 4[/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The original line is y = 4x + 3
Comparing with the general equation above
Slope = 4
Since the lines are parallel their slope are also the same
Slope of parallel line = 4
The equation of the line using point (1,8) and slope 4 is
[tex] y - 8 = 4(x - 1) \\ y - 8 = 4x - 4 \\ y = 4x - 4 + 8[/tex]
We have the final answer as
[tex]y = 4x + 4[/tex]

"Now that you’ve created your hypotheses, it’s time to prove them. First, look at the sum of two rational numbers. Let’s say they are two rational numbers, x and y. Because they’re rational, they can be written as a ratio of integers. Let x = a/b and y = C/D, where a, b, c, and d are integers and b and d do not equal 0. The process for finding the sum x + y in terms of a, b, c, and d is shown." Question:Based on this sum and using the closure property of integers, what conclusion can you make about the sum of two rational numbers? Explain your answer.
Answer:
hello some parts of your question is missing attached below is the missing part
answer: the sum Given it can seen that according to the closure property of Rational numbers the addition of two rational numbers will sum up to a rational number provided that the rational numbers ≠ 0 and a set of rational number is closed under the closures property rule i.e x + y = y + x
Step-by-step explanation:
using the closure property and based on the sum given :
From the sum Given it can seen that according to the closure property of Rational numbers the addition of two rational numbers will sum up to a rational number provided that the rational numbers ≠ 0 and a set of rational number is closed under the closures property rule i.e x + y = y + x

Answer:

Step-by-step explanation:
the area of a triangle is
[tex]A=\frac{1}{2}(h)(b)[/tex]
so if we take as
[tex]from\:(x_1,y_1)\rightarrow(x_2,y_1)[/tex]
so the base is
[tex]b=x_2-x_1[/tex]
so the height is
[tex]from\:b\rightarrow(0,0)[/tex]
the distance is
[tex]h=y_1-0[/tex]
so the area is
[tex]A=\frac{1}{2}(y_1+0)(x_2-x_1)\\\\=\frac{1}{2}(y_1)(x_2-x_1)[/tex]
so the answer is B

Answer:
[tex]\frac{1}{72}[/tex]
Step-by-step explanation:
Using the rule of exponents
[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex] thus
[tex]2^{-3}[/tex] = [tex]\frac{1}{2^{3} }[/tex] = [tex]\frac{1}{8}[/tex]
[tex]3^{-2}[/tex] = [tex]\frac{1}{3^{2} }[/tex] = [tex]\frac{1}{9}[/tex]
Then
[tex]\frac{1}{8}[/tex] × [tex]\frac{1}{9}[/tex] = [tex]\frac{1}{72}[/tex]
Answer:
1/72.
Step-by-step explanation:
2^-3 = 1 / 2^3 = 1/8.
3^-2 = 1/3^2 = 1/9
So the answer is 1/8 * 1/9
= 1/72.

7.) Calculate the percentage growth rate for a country with a population of 7 million in a year in
which it had 100,000 births, 70,000 deaths, 30,000 immigrants and 40,000 emigrants.
Answer:. The growth rate is 0.3%
0.286% if a more accurate percentage is required.
Step-by-step explanation: Add Births and immigrants
100,000+30000= 130,000
Subtract deaths and emigrants
-70,000 -40,000
Net gain in population: 20,000
Divide 20000/7000000=0.002857142857
Round and change to percent:
0.286% or 0.3%
