Susan said, "I multiplied 100 by 47, and then I removed one group of 47." Write an expression to represent how Susan solved 99x47. Then evaluate the expression.
Answer:
The expression of how Susan solved 99 × 47 is;
99 × 47 = 100 × 47 - 47
The evaluation of the expression is;
99 × 47 = 4653
Step-by-step explanation:
The question relates to the simplification of the multiplication of two numbers by the use of a combination multiplication of one of the numbers, 'x', with the nearest 10s or 100s of the other number, 'y', followed by the subtraction or addition operation of the product between the number 'x' and the difference between the specified 10s or 100s and 'y';
The given information on how Susan solved the equation 99 × 47 can be presented as follows;
99 × 47 = (100 - 1) × 47 = 100 × 47 - 47
The expression of how Susan solved 99 × 47 is therefore presented as follows;
99 × 47 = 100 × 47 - 47
The evaluation of the expression is therefore given as follows;
100 × 47 - 47 = 4700 - 47 = 4653.

Given:
The area model.
The area of the shape is 82 square units.
To find:
The correct equation for the given situation.
Solution:
We know that, area of a rectangle is
[tex]Area=Length \times Width[/tex]
The figure is divided into 3 rectangles. Using this formula, the area of each rectangle is
[tex]A_1=(x)\times (3x)=3x^2[/tex]
[tex]A_2=(x)\times (4)=4x[/tex]
[tex]A_3=(3)\times (3x)=9x[/tex]
Now, the total area is equation to 82 square units.
[tex]A_1+A_2+A_3=82[/tex]
[tex]3x^2+4x+9x=82[/tex]
[tex]3x^2+13x=82[/tex]
Since the required equation is [tex]3x^2+13x=82[/tex], therefore, the correct option is C.
What is the positive solution to this equation?
4x²+12x=135
Answer:
4.5

Which value for x makes the sentence true?
18x = 360
Answer:
X=20
Step-by-step explanation:
360/18=20
Answer:
x=20
Step-by-step explanation:
18x=360
divide both sides by 18x
[tex]\frac{18x}{18}[/tex]=[tex]\frac{360}{18}[/tex]
simplify
x=20

-1 2/3 divided by (-2 1/5)
Answer:0.75757575757
Answer:
Fraction Form
25/33
Decimal Form
0.75
Step-by-step explanation:
First, convert the mixed fraction into an improper fraction, so it would look like:
-5/3 / (-11/5)
Next, divide. Remember, when multiplying fractions all you do is flip the one in parantheses and make both of them positive, so it would look like:
5/3 x 5/11
Finally, multiply so you do the two top numbers which is 5 x 5= 25 and the two bottom numbers so 11 x 3 is 33. Then your final answer is 25/33
3n - 17 = -50
two step equations help please
Answer:
n = -11
Step-by-step explanation:
3n - 17 = -50
⇒ 3n = -33
⇒ n = -11
Answer:
n = -11
Step-by-step explanation:
3n - 17 + 17 = -50 + 17
3n = -33
3n/3=-33/3
n = -11

Reshawn is buying 3 books in a trilogy set for $24.81. He will save $6.69 by buying the trilogy set instead of buying individual books. If each book costs the same amount, how much does each of the 3 books cost when purchased individually? Show your work.
$10.50
Explanation:
Let x be the cost of the individual books. Then 24.81=3x−6.69
3x= 24.81+ 6.69 =31.50
x=31.50/3=10.50

Collin Buys a TV for £720 depreciate at a rate of 4% per year how much will it be worth in three years
Answer:
The worth of the TV after 3 years is £809.90208
Step-by-step explanation:
The answer to given question can be found from the anual depreciation formula and solving for the Future Value (F. V.) of the machine
The given parameters of the TV are;
The amount at which Collin buys the TV, P = £720
The rate at which the TV depreciates at, R = 4%
The number of years the depreciation is applied, T = 3 years
The amount the TV is worth after three years, 'A', is given as follows;
[tex]A = P \cdot \left(1 + \dfrac{R}{100} \right )^T[/tex]
By plugging in the known values, we have;
[tex]A = 720 \cdot \left(1 + \dfrac{4}{100} \right )^3 = 809.90208[/tex]
The amount the TV is worth after three years, A = £809.90208
Jane invests £1,200 in a bank account which
earns interest at the rate of 6% per annum.
Find the value of a) the investment after 5
years
Answer:
£1560
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year,
then, solving our equation
I = 1200 × 0.06 × 5 = 360
I = £ 360.00
The simple interest accumulated
on a principal of £ 1,200.00
at a rate of 6% per year
for 5 years is £ 360.00.
Write an equation.
Find the constant of proportionality and write an equation for the proportional relationship.
y = 10 and x = 8
Given:
y is proportional to x.
y=10 and x=8.
To find:
The constant of proportionality and the equation for the proportional relationship.
Solution:
y is proportional to x.
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
Where, k is the constant of proportionality.
Putting y=10 and x=8, we get
[tex]10=k(8)[/tex]
[tex]\dfrac{10}{8}=k[/tex]
[tex]\dfrac{5}{4}=k[/tex]
Putting [tex]k=\dfrac{5}{4}[/tex] in (i), we get
[tex]y=\dfrac{5}{4}x[/tex]
Therefore, the contestant of proportionality is [tex]k=\dfrac{5}{4}[/tex] and the equation for the proportional relationship is [tex]y=\dfrac{5}{4}x[/tex].
