Dylan invested some money into his bank.
He agreed a simple interest rate of 3% per annum for a period of 2 years
At the end of the 2 years period the value of his investment increased by 72%
Work out the value Dylan initial investment was?
Answer:
the initial investment is $1,200
Step-by-step explanation:
The computation of the initial investment is shown below:
As we know that
Let us assume the investment be 100
So, the investment increased be 72
So,
Simple interest = Principal × rate of interest × time period
72 = Principal × 3% × 2 years
So, the principal is
= 72 ÷ 3% × 2
= $1,200
hence, the initial investment is $1,200
Write an expression equivalent to
-3 + 2/3y − 4 − 1/3 y
Answer:
1/3y-7
Step-by-step explanation:
For these kinds of problems you want to combine like terms. 2/3y and -1/3y are like terms, and when adding them together, or subtracting 1/3y from 2/3y, you get 1/3y. -3 and -4 are like terms, and adding them together gives you -7. The final expression can be written as 1/3y-7.
To write an equivalent expression, we need to simplify the given expression by combining like terms. Like terms are terms that have the same variable and exponent. We can use the distributive property to remove parentheses or other grouping signs to then combine like terms.
The given expression is -3 + 2/3y - 4 - 1/3y. We can see that there are no parentheses or grouping signs, so we can skip that step. We can also see that there are two like terms: 2/3y and -1/3y. We can combine them by adding their coefficients: 2/3 + (-1/3) = 1/3. So, we get:
-3 + 2/3y - 4 - 1/3y = -3 - 4 + (2/3 - 1/3)y = -7 + (1/3)y
This is the simplified expression that is equivalent to the given expression.

Step-by-step explanation:
what of the following us a solution to the system of equations
Answer:
(- 1, - 5 )
Step-by-step explanation:
Given the 2 equations
y = 3x - 2 → (1)
6 + y = - x → (2)
Substitute y = 3x - 2 into (2)
6 + 3x - 2 = - x
4 + 3x = - x ( add x to both sides )
4 + 4x = 0 ( subtract 4 from both sides )
4x = - 4 ( divide both sides by 4 )
x = - 1
Substitute x = - 1 into (1) for corresponding value of y
y = 3(- 1) - 2 = - 3 - 2 = - 5
solution is (- 1, - 5 )

Convert the equation into Standard Form.
x^2 + y^2 + 10x - 12y+45 = 0
Answer:
(x−5)^2+(y+6)^2=9
Step-by-step explanation:
Suppose that y varies directly with x
and y=
= 10 when x = 20. What is y
when x = 15?
Be sure to simplify your answer.
Answer:
[tex]10 \times 2 = 20 \\ 5 \times 3 = 15[/tex]
answer:10×2=20
5×3=15
Answer:
y = 7.5
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 10 when x = 20
10 = 20k ( divide both sides by 20 )
[tex]\frac{1}{2}[/tex] = k
y = [tex]\frac{1}{2}[/tex] x ← equation of variation
When x = 15 , then
y = [tex]\frac{1}{2}[/tex] × 15 = [tex]\frac{15}{2}[/tex] = 7.5
Wendy borrowed a 370-page book from the library. She has already read 20 pages. The book is due back to the library in 7 days. Write an inequality to find the number of pages per day Wendy must read in order to finish the book before it is due.
0 points
Answer:
n ≥ 50
Step-by-step explanation:
Total pages = 370
Read pages = 20
Number of days remaining = 7
Reading rate per day = n
7n + 20 ≥ 370
7n ≥ 370 - 20
7n ≥ 350
n ≥ 350/7
n ≥ 50 pages per day for the remaining 7 days

The perimeter of a rectangular painting is 364cm . If the length of the painting is 96cm, what is its width?
Answer:
The width would be 86cm
Step-by-step explanation:
Perimeter is (Width*2) +(Length*2)
Length is 96, multiply by 2 : 96*2 = 192
Subtract this from the total perimeter (364-192 = 172)
Divide this by 2 to get 1 width value (172/2 = 86)
86 cm

2) Byron made a scale model of his
favorite car. The car is 14 feet long.
Byron's model is 3.5 inches long. What
is the scale Byron used to make his
model car?
9514 1404 393
Answer:
1 : 48
Step-by-step explanation:
The scale is ...
3.5 in : 14 ft = 3.5 in : 168 in = 1 : 48
Answer:
Solution :-At first we need to convert ft into in
1 ft = 12 in
14 × 12 = 168 inches
Ratio = 3.5 : 168
Ratio = 1:48

Solve for x, rounding to the nearest hundredth.
70 - 2^3x = 35
Answer:
x=4.375
Step-by-step explanation:
Answer:
x= 1.71
Step-by-step explanation:
We need to isolate x in the equation, first subtract 70 from the left side, so the equation is, -[tex]2^{3x\\}[/tex]=-35. There is a negative sign in both equations so we cancel them out so our equation is [tex]2^{3x\\}[/tex]=35. Now we use log, so our equation now looks like {log(35)/log(2)}/3=x. When we do it out we get that x=1.70976, and when rounded we get, x-1.71.
