Answers

Answer 1

Hi!

Expression: 6(2)+3

Ethan is 3 years older than twice his brother's age.

6(2)+3

12+3

15

Ethan is 15.

Happy studying!
~SimpleGirl~

Answer 2

Start with Ethan being twice as old as his brother Adrian. If Adrian's age is represented by x, then we can use the expression 2x. Ethan is also three years older than twice that age though, so modify the expression to add three years.

2x + 3. Now substitute Adrian's age, 6, into x and solve.

2(6) + 3
12 + 3
15.
If Adrian is 6, then Ethan is 15.

Answers

To get the equivalent fractions, you simply have to multiply the fraction with another fraction that would equal to 1.

2/8 x 2/2 (this is equal to 1) = 4/16; 1/4

3/8 x 2/2 = 6/16; 9/24

4/8 x 2/2 = 8/16; 1/2

Christian is comparing two checking accounts. One has a monthly fee of $7 and a per-check fee of $0.20, and the other has a monthly fee of $8 and a per-check fee of $0.15. What is the minimum number of checks Christian needs to write for the second bank to be a better option? A. 22 B. 21 C. 19 D. 18

Answers

Answer:

Option B. 21

Step-by-step explanation:

Christian is comparing two checking accounts.

First account has monthly fee = $7.00

and a per check fee = $0.20

Second account has monthly fee = $8.00

and a per check fee = $0.15

Now make equation to compare both accounts

7 + 0.20x = 8 + 0.15x

7 = 8 + 0.15x - 0.20x

7 = 8 - 0.05x

7 - 8 = -.05x

-1 = - 0.05x

x = [tex]\frac{1}{0.05}[/tex]

x = 20

On 20th check first account and second account are charged equal.

on 21st check second account would be a better option.

There are 450 seats in the lower level of a concert hall with b balcony seats in upper level so far 170 tickets have been sold which Is 1/5 of the total number of seat in concert hall how many tickets sold are balcony seats

Answers

There are 400 balcony seats.

Let b be the number of balcony seats. There are 450 lower seats; this makes the total number of seats 450+b. We know that there were 170 tickets sold, and that this is 1/5 the total number of seats; therefore our equation is
1/5(450+b)=170

Use the distributive property with the 1/5:
1/5*450 + 1/5*b = 170
90 + 1/5b = 170

Subtract 90 from both sides:
90 + 1/5b - 90 = 170 - 90
1/5b = 80

We can also write 1/5b as b/5:
b/5 = 80

Multiply both sides by 5:
(b/5) * 5 = 80 * 5
b = 400

You can add the number of seats and can take its one fifth and equate it to 170 to get the number of total seats.

There are total 400 tickets sold for balcony seats.

How to calculate the number of seats from tickets' data?

Since the number of seats will be equal to that of tickets sold (assuming all seats will be covered), thus we can relate both the data.

How to find the total number of tickets sold for balcony seats?

It is givn that 170 is 1/5th of the total seats.

Since total seats = 450 seats of the lower level + b seats of the balcony

Thus, we have:

[tex]170 = \dfrac{450 + b}{5}\\\\450 + b = 170 \times 5\\\\b = 850 - 450 = 400[/tex]

Thus, there are total 400 balcony seats and thus same number of tickets will be sold for balcony seats.

Thus, There are total 400 tickets sold for balcony seats.

The points (10, 6) and (7, u) fall on a line with a slope of -4/3. what is the value of u?

u=

Answers

Answer:
u = 10

Explanation:
The slope of the lone can be calculated as follows:
slope = (y2-y1) / (x2-x1)

We are given:
slope = -4/3
point (10,6) representing (x1,y1)
point (7,u) representing (x2,y2)

Substitute with the givens in the above equation and solve for u as follows:
slope = (y2-y1) / (x2-x1)
-4/3 = (u-6) / (7-10)
-4/3 = (u-6) / -3
4/3 = (u-6) / 3
3*4 = 3*(u-6)
4 = u-6
u = 4+6
u = 10

The total earnings for hours 1 and 2 are given. Each regular-sized coffee costs the same price, and each large-sized coffee costs the same price. The system of equations can be used to represent the situation.

Answers

X represents Regular Sized Coffee.
y Represents Large Sized Coffee.
The intersection is (3,5).
The cost of 1 regular and 1 large size coffee is 8 dollars.
The total earnings for hour 3 are $63.

8 and 9 are coefficients for x so they represent the regular sized coffee.
6 and 11 are coefficients for y so they represent Large sized coffee.
To find the intersection you can graph the equations. as shown in the attachment.
x is 3 and y is 5. Add them together to get 8 dollars.
plugging in 3 for x and 5 for y gives you 63 dollars.
6x+9y = 6(3) + 9(5) = 63.

a quadrilateral is plotted on the coordinate plane. Each of its vertices undergoes the same transformation.Which rule below represents a transformation that does not preserve the length of the sides of the quadrilateral?

Answers

There are two main types of transformations:
a) Rigid Transformations
b) Non-Rigid Transformations

Rigid Transformations, as their name indicate, do not alter the size or shape. These include reflection, rotation and translation

Non-Rigid Transformations, do not preserve the size. The shape remains the same. This include Dilation.
The question asks to find a rule which do not preserve the lengths of the sides of the Quadrilateral. So one thing is for sure. The quadrilateral has undergone non-rigid transformation i.e Dilation. Dilation involves both contraction and expansion. So the rule which will either expand or contract the given quadrilateral will be the right choice to the given question.

Answer:

(X,Y) ——> (3x - 2, y - 3)

Step-by-step explanation:

Because it’s multiplying X by 3 meaning that is a dilation

Solve the quadratic equation by completing the square.
