Solve for the variable: p - 4.2 = 2. Show your work
Answer:
6.2
Step-by-step explanation:
P - 4.2 =2
we have to no separate the variables and constants
so , when we move 4.2 to the other side ( other side of 2) it will be something like this
p = 2+4.2
as you can wee when we moved 4.2 to the other side the operation changed from ,minuus to plus sign .
now just do what it says
formula :
=p-4.2=2
=p = 2+4.2
= 2+ 4.2= 6.2
so,
p=6.2
write the formula , I think no need to write explanation

A city has a population of 340,000 people. Suppose that each year the population grows by 5.25%. What will the population be after 15 years?
Answer:
Future population = 720800
Step-by-step explanation:
Below is the calculation of population after 15 years.
Given the present population = 340000
Growth in population = 5.25%
Use below formula to find the values:
Future population = Present population ( 1 + r)^n
Future population = 340000 ( 1 + 5.25%)^15
Future population = 340000 (2.15)
Future population = 720800
Find a point on the line and the line's slope.
y+4=-3/2(x+7)
Answer:
The slope is 3/2 and a point on the line is (-7,-4)
Step-by-step explanation:
Point slope form of a line is
y -y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y+4=-3/2(x+7)
y - -4 = 3/2 ( x - -7)
The slope is 3/2 and a point on the line is (-7,-4)

Macy's buys a coat from the manufacturer for $22.00. They markup the coat by 75%. Ms. Tonyes buys the coat and uses a 15% off coupon. How much does Ms. Tonyes pay for the coat before tax?
Answer:
Toney buys the coat for $ 14.8.
Step-by-step explanation:
Cost of coat =$ 22
Mark up by 75 %
discount = 10 %
Let toney pay $ R for the coat.
So, according to the question
R + 75 % R = 1.75 R
Now the cost is
1.75 R - 15 % of 1.75 R = 22
1.75 R - 0.2625 R = 22
R = 14.8
So, he buy the coat for $ 14.8.
Rewrite y +2> +(6x –9) to isolate the y-term.
Rewrite y +2>2(6x-
Helppppp
Given:
The inequality is:
[tex]y+2>\dfrac{1}{3}(6x+9)[/tex]
To find:
The inequality after isolating the y-term.
Solution:
We have,
[tex]y+2>\dfrac{1}{3}(6x+9)[/tex]
On simplification, we get
[tex]y+2>\dfrac{1}{3}(6x)+\dfrac{1}{3}(9)[/tex]
[tex]y+2>2x+3[/tex]
Subtracting 2 from both sides of the above inequality, we get
[tex]y+2-2>2x+3-2[/tex]
[tex]y>2x+1[/tex]
Therefore, the required inequality is [tex]y>2x+1[/tex].

The LCM of two numbers is 48. The number one in the ratio 2:3. Then Sum of the numbers is:
a) 16
b) 14
c) 32
d)28
Answer:
40
Step-by-step explanation:
Let the numbers be 2x and 3x
Then their L.C.M. = 6x
BUT also their LCM=48
6x=48
x=48/6
x=8
So,
First number=2x=2x8=16
Second number=3x=3x8=24
The numbers are 16 and 24.
Hence required sum =(16+24)=40
So none of the options are correct

Witch statement about a quadrilateral is true 1. A rhombus has exactly one pair of parallel sides. 2. A trapezoid has two pairs of parallel sides. 3. All rectangle are squares. 4. Some rhombus have four right angles
Answer:
Statement 4 is true.
Step-by-step explanation:
- Statement 1 is false because a rhombus has 4 equal sides with 2 pairs being parallel to each other.
- Statement 2 is false because a trapezoid usually has only 2 sides that are parallel while the other 2 are not parallel. Thus it has only a pair of parallel sides.
- A square must have all 4 sides equal. But rectangles don't have all 4 sides equal and so the statement is false.
- Rhombus has all 4 sides equal and where it has all interior angles as right angles, it is called a square. Thus, some rhombus have all 4 interior angles as right angles.

Use the Pythagorean theorem to classify the triangle
formed by the three fences. Which is true about the
numbers 5, 12, and 13?
Answer:
they are equal
Step-by-step explanation:
The triangle with sides 5, 12, 13 is a right triangle because
a^2+b^2 = c^2
5^2+12^2 = 13^2
25+144 = 169
169 = 169
