Answer:
y = 1/2
Step-by-step explanation:
Step 1: Solve for y
2y + 3 = 4y + 2
2y + 3 - 2 - 2y = 4y + 2 - 2 - 2y
1 / 2 = 2y / 2
1/2 = y
Answer: y = 1/2
Step-by-step explanation:
2y + 3 = 4y + 2
-2y + 3 = 2
-2y = -1
2y = 1
y = 1/2
y = 0.5
You buy a watch for $60. Your friend buys the same watch a month later. It is now sold at a discount of 15%. What is the new sale price?
Answer:
$9.00
Step-by-step explanation:
~~~~Hey there~~~~
1. Since it was 15% discount, that means you have to solve 15% of 60, which is equivalent to 0.15 x 60.
2. Since the product of 0.15 and 60 is 9, then 9 is your answer.
3. Your final answer is $9.00
Hope this helped!

Answer:
56
Step-by-step explanation:
You would first do 60 divide by 15 and get 4. Then you subtract 4 from 60 and get 56 as your answer.
A shoreline is eroding at a rate of 1/3 foot per 3 months. How many feet are eroding per year?
The number of feet the shoreline is eroding per year is 1 ⅓ feet.
How many feet are eroding per year?
Rate of shoreline eroding per 3 months = 1/3 foot
Number of 3 months in a year = 12 months / 3 months
= 4
Number of feets of the shoreline eroding per year = Rate of shoreline eroding per 3 months × Number of 3 months in a year
= 1/3 × 4
= 4/3 feet per year
Therefore, the shoreline erodes 1⅓ feet per year
Solve -8(2z-3) Equivalent to -16z-3
Answer:
-16z + 24
Step-by-step explanation:
Apply the Distributive Property of Multiplication:
-8(2z-3) = -16z + 24
Answer:
-27
Step-by-step explanation:
-8 ( 2z - 3 ) = -16z - 3
distribute -8
-16z + 24 = -16z - 3
add 16z on right side
z + 24 = - 3
subtract 24 on left side
z = -27

Translate six minutes less then bobs time in a algebraic expression
Answer:
B-6
Step-by-step explanation:
If (B) represents Bob's time, six minutes less than Bob's time is B-6=T where (T) represents the time six minutes less than Bob's time.
The phrase 'six minutes less than Bob's time' can be translated into the algebraic expression 'B - 6', where 'B' represents Bob's time.
Explanation:The given phrase 'six minutes less than Bob's time' can be written as an algebraic expression. Algebraic expressions are mathematical phrases containing numbers, variables (like 'Bob's time'), and operations. In this case, we can symbolize 'Bob’s time' as a variable, let’s choose 'B'. Then 'six minutes less than Bob's time' translates to 'B - 6' in an algebraic expression. That’s because 'less than' implies subtraction and it always means you subtract from the number or variable stated after the expression, in this case, 'Bob's time' or 'B'.

Find the value of x to the nearest tenth.
Answer:
16. The answer is 16.5
17. The answer is Sin33.1°
18. The answer is 38.2
Step-by-step explanation:
In rounding up figures, number 1 to 4 is rounded up to 0 while numbers 5 to 9 is rounded up to 1.
16. Two sides in the right angle triangle are involved, the opposite side and the adjacent side, hence we use the tangent.
Tan36°=12/x
Cross multiply
x(tan 36°)= 12
Divide both sides by tan36°
x= 12/tan36°
16.516583
Rounded to the nearest tenth, we have 1 as the digit hundredth, which will be rounded up to 0.
Added to the tenth digit, still remains 5.
Answer therefore is 16.5
17. Two affected sides here is the opposite side and hypothenus sid, hence we use the sine.
sin x=12/22
= 33.055°
The digit hundredth is 5, which is rounded up to 1. Added to the tenth digit, we have 0+1=1
Answer is 33.1
18. Two affected sides are the opposite side and hypothenus side, we also use the sine.
Sin58°=x/45
Make x the subject
x=45/sin58°
38.162
6 is the digit hundredth, and it is rounded up to 1. Adding 1 to 1, the tenth digit in the figure above, we have our answer as

the first term of an arithmetic sequence is -27. the common difference of the sequence is 6. What is the sum of the first 30 terms
Answer:
1800
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = - 27 and d = 6, thus
[tex]S_{30}[/tex] = [tex]\frac{30}{2}[/tex] [ (2 × - 27) + (29 × 6) ]
= 15( - 54 + 174)
= 15(120)
= 1800
The sum of the first 30 terms of the arithmetic sequence, is 1800.
In an arithmetic sequence, the sum of the first n terms can be calculated using the formula:
Sum = n/2 × (2a + (n-1)d), where:
n is the number of termsa is the first termd is the common differenceGiven:
First term (a) = -27Common difference (d) = 6Number of terms (n) = 30Plugging in these values, we get:
Sum = 30/2 × (2(-27) + (30-1) × 6)
Calculating step-by-step:
Calculate the first part: 30/2 = 15Calculate inside the parentheses: 2(-27) + (30-1)6 = -54 + 29*629 × 6 = 174-54 + 174 = 120Final calculation: 15 × 120 = 1800Therefore, the sum of the first 30 terms of the arithmetic sequence is 1800.

2. Ben is 8 and Ishaan is 2
3. Ben is 12 and Ishaan is 3
4. Ben is 16 and Ishaan is 4

1. Ben is 7 and Ishaan is 4
2. Ben is 11 and Ishaan is 5
3. Ben is 15 and Ishaan is 6
4. Ben is 19 and Ishaan is 7
Ben is currently 12 years older than Ishaan. To find the difference, take Ben's age and subtract Ishaan's age.
1. 7 - 4 = 3
2. 11 - 5 = 6
3. 15 - 6 = 9
4. 19 - 7 = 12

At the mission museum Mrs. Perez visited over break, there is a pond like the one below that has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 10 m. The inner edge of the sidewalk is a circle with a radius of 8 m.
(a) Write and simplify an expression for the exact area of the sidewalk. (4 points possible)
(b) Find the approximate area of the sidewalk. Use 3.14 to approximate π. (3 points possible)
Answer:
The formula for area of a circle is : A = PI x r^2
A) find the are of the two circles, subtract the two to find the area of the side walk:
Outside circle: A = PI x 10^2
Area = 100PI
Inner circle: A = PI x 8^2
Area = 64PI
Area of sidewalk:
100PI - 64 PI = 36PI

A certain forest covers an area of 8.25%. Suppose that each year this area decreases by 4800km^2. What will the area be after 5 years?
Solution:
The decreasing function is given as:
[tex]y = a(1-r)^t[/tex]
Where,
y is future value
a is initial value
r is decreasing rate
t is number of years
From given,
a = 4800
t = 5
[tex]r = 8.25 \% = \frac{8.25}{100} = 0.0825[/tex]
Therefore,
[tex]y = 4800(1 - 0.0825)^5\\\\y = 4800 \times 0.9175^5\\\\y = 4800 \times 0.6501\\\\y = 3120.841[/tex]
Thus the area after 5 years is 3120.841 square kilometer

Two lines intersect to form the angles shown.
Which statements are true?
Select each correct answer.
m<1=100 degrees
m<3=80 degrees
m<2= 80 degrees
m<3=m<1
Answer:
m∠3=80 degrees
m∠3=m∠1
Step-by-step explanation:
When two lines intersect, the opposite angles are equal. They are called vertical angles. That means for this problem:
m∠1 = m∠3 *Last option is true
m∠2 = 100° *Third option is false
A straight line is always 180°. When it is cut up, the sum of the angles is 180°. They are called suppementary angles. These are supplementary:
100° + m∠3 → m∠3 = 80° *Second option is true
m∠1 + 100° → m∠1 = 80° *First option is false
m∠1 + m∠2 → One or the other is 100° and 80°
m∠2 + m∠3 → One or the other is 100° and 80°

First, we need to figure out how much you want to borrow. You said you wanted to spend $5,000, and you will put $500 down. Based on that, we can estimate your taxes to be $340. Put those numbers to see how much money you will need for your loan.
Answer: You will need $4,160 for the loan.
The money that will need for the loan is $4160.
What is down payment?A down payment is a sum of money the buyer pays at the outset of a large transactions. The down payment represents a portion of the total purchase price, and the buyer will often take out a loan to finance the remainder.
For the given situation,
The total amount wanted to spend = $5000
Down payment = $500
Tax amount = $340
Money that will need for the loan can be calculated as
⇒ [tex]5000-(500+340)[/tex]
⇒ [tex]5000-840[/tex]
⇒ [tex]4160[/tex]
