3 times x increased by 20 as a algebraic expression
Answers
Answer:
3x+20
Step-by-step explanation:
“3 times x” means 3x
and “increased by 20” means to add 20 to the equation.
if you were to solve this equation, the answer to the first step would be 6.666!
divide each side by 3. 3/3 is 1, and 20/3 is 6.666! therefore, the 1 cancels out and you get this number, which is the value of x.
now, for the second step, you would get 39.998, which is your overall answer! all you have to do is replace x with the answer from the previous step (6.666)

Tim buys a torch and a battery
The torch costs eleven times as much as the battery
Tim pays with a £10 note and gets £4.84 change
How much does the battery cost?
Answers
The cost of battery is £0.43.
Given,
In the question:
Tim buys a torch and a battery
The torch costs eleven times as much as the battery and
Tim pays with a £10 note and gets £4.84 change.
To find the how much does the battery cost?
Now, According to the question:
Let cost of battery = £ x
So, Cost of torch = £ 11x
Based on the given conditions :
=> x + 11x = £ 10 - £ 4.84
=> 12x = £ 5.16
=> x = £ 5.16/ 12
=> x = £ 0.43
Hence, The cost of battery is £0.43.

Answers
The fraction form of 8 1/6 is 49/8 as the definition of fraction says, "An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are divided".
What is fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are divided. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator. A fraction merely informs us of the number of parts that make up the whole. The slash that is written between the two numbers identifies a fraction. The numerator is the highest number, and the denominator is the lowest number. 1/2, for instance, is a fraction.
Here,
8 1/6=(6*8+1)/8

Answers
The width of the scale model given a height of 10 inches as in the task content is; 3.75 inches.
What is width of the scale model given a height of 10 inches?It follows from the task content that the width of the scale model is to be determined given a height of 10 inches.
According to the design, the lawnmower measures; 8 feet in height, 3 feet width, and 7 feet in length.
Hence, since 8 feet in height corresponds to 10 inches on the scale, the width on the scale can be determined by proportion as;
8/10 = 3/x
x = ( 10 × 3 ) / 8
x = 30/8
x = 3.75 inches.
Therefore, the width on the scale as required is; 3.75 inches.

Writing the equation form for each statement -
Let the variable be represented as y.
One third times the difference of thirty and a variable is three fourths1/3(30 - y) = 3/4
one third times the quantity 30 minus y equals three fourths1/3×30 - y = 3/4
one third times the quantity y minus 30 equals three fourths1/3×y - 30 = 3/4
one third times 30 minus y equals three fourths1/3(30 - y) = 3/4
one third times y minus 30 equals three fourths1/3(y - 30) = 3/4
Based on the interpretation of all the sentences in equation form, we find the statement 3 to be same as original statement. Solving the equation to get the value of y.
1/3(30 - y) = 3/4
10 - y/3 = 3/4
10 = 3/4 + y/3
10 = (3×4 + y×4)/12
10×12 = 12 + 4y

Answers
Torren will have $5169 in the account at the beginning of year 8. Option A is correct.
The following formula can be used to calculate the compound interest.
[tex]A(n) = P(1 + r)^{(t- 1)}[/tex]
where,
A(n) denotes the final sum.
P stands for the initial deposit.
r denotes the interest rate (in decimal).
t denotes the time (in year).
The compound interest will be C.I = A - P in this case.
We are given in the question;
The account's initial deposit is $4500, and the term is 8 years.
As a result,
A = 4500 and
t = 8
As we all know, interest is compounded once a year.
We shall divide the interest rate in percentage form by 100 to convert it to decimal form.
r = 2% = 2/100
⇒r = 0.02
The given equation is
[tex]A(n) = 4500(1 + 0.02)^{(n- 1)}[/tex]
Substituting the given values in the above equation, we will get,
[tex]A(n) = 4500(1 + 0.02)^{(8- 1)}[/tex]
[tex]A(n) = 4500(1 + 0.02)^{7}[/tex]
[tex]A(n) = 4500 \times 1.14868[/tex]
[tex]A(n) = 5169.06[/tex]

Area of irregular shape is 41.13m².
Define area.The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina. Area can be interpreted as the quantity of material with a specific thickness required to create a model of the shape or as the quantity of paint required to completely cover a surface in a single coat.

Company B charges an initial fee of $85 for the rental plus $2 per mile driven. Let AA represent the amount Company A would charge if Mia drives xx miles, and let BB represent the amount Company B would charge if Mia drives xx miles. Write an equation for each situation, in terms of x,x, and determine which company would be cheaper if Mia needs to drive 80 miles with the rented truck.
Answers
Answer:
(a.): Company A: 3x + 30; Company B: 2x+85
(b.) Company B is cheaper as it would cost $245 for Mia to drive 80 miles
Step-by-step explanation:
The equations we need are linear and we can think of them as such. x represents the slope (cost per mile) and the initial fee represents our y-intercept or constant (amount paid before Mia ever drives)
(a.): Thus, for company A, we have y = 3x + 30 and for company B we have y = 2x + 85.
(b.) Since we know that Mia needs to drive 80 miles, we plug this into x for both companies and find which one is lower
Company A: 3(80) + 30 = $270
Company B: 2(80) + 85 = $245
Company B's price would be lower for Mia's needs.
