Let the 2 digit number be ab remembering that ab=10a+b
a=b-4...........equation 1
10a+b=3(a+b)+2........... equation 2
take a's value in equation 1 and plug it into equation 2
10(b-4)+b=3(b-4)+3b+2
5b=30
b=6 units digit
a=6-4=2 tens unit
number is 26

Josie read 246 pages of a book last month her older brother says he read about 3 to 4 times as many pages as Josie explain why 2
Lubov Fominskaja [6]

Answer:

2500 is not a reasonable estimate.

Step-by-step explanation:

We are given the following in the question:

Number of pages read by Josie = 246

Pages read by older brother = 3 to 4 times as many pages as Josie

If x represents the number of pages read by her brother, we can write:

3(\text{Pages read by Josie})\leq x \leq 4(\text{Pages read by Josie})

Putting values, we get,

3(246) \leq x \leq 4(246)\\738 \leq x \leq 984

Since, 2500 does not lie in this interval

738 \leq 2500 \nleq 984

Thus, 2500 is not a reasonable estimate for the number of pages that Josie's brother read.

Which mized numbers can you write for 24/7
IgorLugansk [536]
How many times does 24 go into 7?

7 × 1 = 7
7 × 2 = 14
7 × 3 = 21
7 × 4 = 28

7 goes into 24 only three times, leaving three remainder. So you would write it like this: 3 \frac{3}{7}. 7 goes into 24 three times, there is three left over as remainder, and the denominator from before is 7. Thus the answer.

I do hope this helped :))

Q5: Identify the graph of the equation and write an equation of the translated or rotated graph in general form.
MAVERICK [17]

Answer:

d.\:ellipse;\:3x^2+y^2+6x-6y+3=0.

Step-by-step explanation:

The given conic has equation;

3x^2+y^2=9

Divide through by 9.

\Rightarrow \frac{3x^2}{9}+\frac{y^2}{9}=\frac{9}{9}

\Rightarrow \frac{x^2}{3}+\frac{y^2}{9}=1.

This is an ellipse centered at the origin;

This ellipse has been translated so that the center is now at;

(-1,3)

The translated ellipse has equation;

\frac{(x+1)^2}{3}+\frac{(y-3)^2}{9}=1.

Clear the fraction;

3(x+1)^2+(y-3)^2=9.

Expand;

3(x^2+2x+1)+(y^2-6y+9)=9.

3x^2+6x+3+y^2-6y+9=9.

Write in general form;

3x^2+y^2+6x-6y+9-9+3=0.

3x^2+y^2+6x-6y+3=0.

The correct choice is D
