Answer: Work below.
3x+6 = 4x+3
6-3 = 4x - 3x
3 = x
or
3x+6 = 4x+3
3x - 4x = 3 - 6
-x = -3

The distance of 15 miles on a map is represented by 2 inches. If the distance between two cities on the map is 8 inches, write a proportion to determine the actual distance between them?
The actual distance between the two cities is 60 miles.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The distance of 15 miles on a map is represented by 2 inches.
This means,
2 inches = 15 miles
Divide both sides by 2.
1 inch = 7.5 miles
Multiply 8 on both sides.
8 inches = 8 x 7.5 miles
8 inches = 60 miles
Thus,
The actual distance is 60 miles.

Kenny is putting a brick border around his irregular shaped garden. Before installing the border, Kenny must
cut the bricks to fit the angles of the garden. Use the given measures to answer the question.
mzA=x
mZB=(5x-5)
m2C =(2x +20)
mZD=(3x-15)
mZE =(4x)
What are the angle measures of each vertex of the garden? Show your work.
Answer:
m<a=36
m<b=175
m<c=92
m<d=93
m<e=144
Step-by-step explanation:
since the shape has 5 sides we can determine the sum of the measure of interior angels with the equation 180×(n-2). replacing n with 5 would bring us to 180×3 equalling 540. since all the angels must add up to 540 we can combine them together to get it to 15x=540. simplify to get x=36. sub in x in the equations.

THE MEASURE OF TWO ADJACENT ANGLES OF THE PARALLELOGRAM ARE IN THE RATIO OF 3:2. FIND THE MEASURE OF EACH OF THE ANGLES OF THE PARALLELOGRAM
Answer:
The adjacent angles are: 72 and 108
Step-by-step explanation:
Given
Angle Ratio = 3 : 2
Required
Find the measure of each angle
Let the angles be [tex]x\ and\ y.[/tex]
Such that:
[tex]x + y = 180[/tex] --- adjacent angles of a parallelogram
and
[tex]x : y = 3 : 2[/tex] --- given
Convert to fraction
[tex]\frac{x}{y} = \frac{3}{2}[/tex]
Cross Multiply:
[tex]2x = 3y[/tex]
Make x the subject:
[tex]x = \frac{3}{2}y[/tex]
[tex]x + y = 180[/tex] becomes
[tex]\frac{3}{2}y + y = 180[/tex]
Take LCM
[tex]\frac{3y + 2y}{2}= 180[/tex]
[tex]\frac{5y}{2}= 180[/tex]
[tex]y = \frac{2}{5} * 180[/tex]
[tex]y = 0.4 * 180[/tex]
[tex]y = 72[/tex]
Recall that:
[tex]x = \frac{3}{2}y[/tex]
[tex]x = \frac{3}{2} * 72[/tex]
[tex]x = 1.5 * 72[/tex]
[tex]x = 108[/tex]
Hence, the adjacent angles are: 72 and 108

Doug earns $10.50 per hour working at a restaurant. On Friday he spent 1 3/4 hours cleaning, 2 1/3 hours doing paperwork, and 1 5/12 hours serving customers. What were Doug's earnings?A$46.97B$47.25C$53.00D$57.75
Answer:
$57.75
Step-by-step explanation:
The total hours spent working :
1 3/4 + 2 1/3 + 1 5/12
7/4 + 7/3 + 17/12
L.C.M = 12
(21 + 28 + 17) / 12
= 66 / 12
= 5 6/12
= 5 1/2
Hourly pay = $10. 50
Total earning :
Total hours * pay per hour
5.5 hours * $10.50
= $57.75
A building casts a 32m shadow when the sun is at an angle of 30 degrees to the vertical. How tall is the building to the nearest meter?
Answer:
16m tall
Step-by-step explanation:
Distance casted by the shadow = 32m = hypotenuse
Angle of elevation = 30 degrees
Required
Height of the building = opposite
Using the SOH CAH TOA identity
sin theta = opp/hyp
sin 30 = x/32
0.5 = x/32
x = 0.5 * 32
x = 16m
Hence the building is 16m tall

Lisa wants to get a new phone. An iPhone 12 is $800 while an iPhone 8 is $600. If the iPhone 12's price goes down by 10% each year and the iPhone 6's goes down by 5% each year, Which phone would be the cheapest for Lisa to get after three years?
Answer:
iPhone 12!!!!!!!!!!!!
Answer:
The iphone 8
Step-by-step explanation:
To find the nth term of a geometric sequence we have the following equation
ar^(n-1)
where a is the first term
r the is the common ratio
n is the term
we can see that the first term for the iphone 12 is 800, the common ratio is .9 (1-.1), and we need the third term
Therefore the price of an iphone 12 after 3 years is
800*.9^(3-1)
which is 648
The iphone 8's first ter is 600 and the common ratio is .95 (1-.05)
using the same equation
600*.95^(3-1)
which is 541.5
